SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	9 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ​ BASIS OF PRESENTATION ​ The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of AptarGroup, Inc. and our subsidiaries. The terms “AptarGroup”, “Aptar”, “Company”, “we”, “us” or “our” as used herein refer to AptarGroup, Inc. and our subsidiaries. All significant intercompany accounts and transactions have been eliminated. Certain previously reported amounts have been reclassified to conform to the current period presentation. In the opinion of management, the unaudited Condensed Consolidated Financial Statements (the “Condensed Consolidated Financial Statements”) include all normal recurring adjustments necessary for a fair statement of consolidated financial position, results of operations, comprehensive income, changes in equity and cash flows for the interim periods presented. The accompanying Condensed Consolidated Financial Statements have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations, although we believe that the disclosures made are adequate to make the information presented not misleading. Also, certain financial position data included herein was derived from the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 but does not include all disclosures required by U.S. GAAP. Accordingly, these Condensed Consolidated Financial Statements and related notes should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2019. The results of operations of any interim period are not necessarily indicative of the results that may be expected for the year. Beginning July 1, 2018, we have applied highly inflationary accounting for our Argentinian subsidiaries pursuant to U.S. GAAP. We have changed the functional currency from the Argentinian peso to the U.S. dollar. We remeasure our peso denominated assets and liabilities using the official rate. In September 2019, the President of Argentina reinstituted exchange controls restricting foreign currency purchases in an attempt to stabilize Argentina’s financial markets. As a result of these currency controls, a legal mechanism known as the Blue Chip Swap emerged in Argentina for reporting entities to transfer U.S. dollars. The Blue Chip Swap rate has diverged significantly from Argentina’s “official rate” due to the economic environment. During the second quarter of 2020, we transferred U.S. dollars into Argentina through the Blue Chip Swap method and we recognized a gain of $1.0 million. This gain helped to offset foreign currency losses due to our Argentinian peso exposure and devaluation against the U.S. dollar. For the nine months ended September 30, 2020, our Argentinian operations contributed less than 2.0% of consolidated net assets and revenues. There are many uncertainties regarding the current COVID-19 pandemic, including the scope of scientific and health issues, the anticipated duration of the pandemic and the extent of local and worldwide social, political and economic disruption it may cause. The pandemic has impacted certain markets within our business, operations and financial results during the nine months ended September 30, 2020 including an overall reduction to net sales within those markets. No impairments were recorded as of September 30, 2020. While the disruption is currently expected to be temporary, there is uncertainty around the duration. Due to significant uncertainty surrounding the situation, future results could change and therefore our results could be materially impacted. ​ ADOPTION OF RECENT ACCOUNTING STANDARDS ​ Changes to U.S. GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Updates (“ASUs”) to the FASB’s Accounting Standards Codification. Effective January 1, 2020, we adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, issued by the FASB in June 2016, as well as the clarifying amendments subsequently issued. We applied the guidance using a modified retrospective approach and accordingly recognized an amount of $1.4 million as the cumulative adjustment to opening retained earnings in the first quarter of 2020. This is based on management's best estimates of specific losses on individual exposures particularly on current trade receivables, as well as the time value of money and reasonable and supportable information that is available at the reporting date about past events, current conditions and forecasts of future economic conditions. On an ongoing basis, we will contemplate forward-looking economic conditions in recording lifetime expected credit losses for our financial assets measured at cost, such as our trade receivables and certain other assets. In January 2017, the FASB issued ASU 2017-04, which provides guidance to simplify how an entity is required to test goodwill for impairm ent by eliminating Step 2 from the goodwill impairment test. As a result, impairment charges are required for the amount by which a reporting unit’s carrying amount exceeds its fair value up to the amount of its allocated goodwill. We adopted the standard on January 1, 2020 and did not record any impairment charges. In August 2018, the FASB issued ASU 2018-15 to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement) by providing guidance for determining when the arrangement includes a software license. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The amendments also require the entity (customer) to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. We adopted the standard on January 1, 2020 and no material impacts were noted. In August 2018, the FASB issued ASU 2018-13, which amends disclosure requirements for fair value measurements. The new standard modifies disclosure requirements including removing requirements to disclose the valuation process for Level 3 measurements and adding requirements to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 measurements. We adopted the standard on January 1, 2020 and no material impacts were noted. Other accounting standards that have been issued by the FASB or other standards-setting bodies did not have a material impact on our Condensed Consolidated Financial Statements. INCOME TAXES ​ We compute taxes on income in accordance with the tax rules and regulations of the many taxing authorities where the income is earned. The income tax rates imposed by these taxing authorities may vary substantially. Taxable income may differ from pre-tax income for financial accounting purposes. To the extent that these differences create temporary differences between the tax basis of an asset or liability and our reported amount in the financial statements, an appropriate provision for deferred income taxes is made. We maintain our assertion that the cash and distributable reserves at our non-U.S. affiliates are indefinitely reinvested. Under current U.S. tax laws, all of our non-U.S. earnings are subject to U.S. taxation. We will provide for the necessary withholding and local income taxes when management decides that an affiliate should make a distribution. These decisions are made taking into consideration the financial requirements of the non-U.S. affiliates and the global cash management goals of the Company. We provide a liability for the amount of unrecognized tax benefits from uncertain tax positions. This liability is provided whenever we determine that a tax benefit will not meet a more-likely-than-not threshold for recognition. The Company is subject to taxation and files income tax returns in the U.S. federal jurisdiction and many state and foreign jurisdictions. The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner inconsistent with its expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. The resolution of each of these audits is not expected to be material to our Condensed Consolidated Financial Statements.

Revenue from Contract with Customer [Abstract]
REVENUE	NOTE 2 – REVENUE At contract inception, we assess the goods and services promised in our contracts with customers and identify a performance obligation for each promise to transfer a good or service (or bundle of goods or services) that is distinct. To identify the performance obligations, we consider all the goods or services promised in the contract, whether explicitly stated or implied based on customary business practices. For a contract that has more than one performance obligation, we allocate the total contract consideration to each distinct performance obligation on a relative standalone selling price basis. Revenue is recognized when (or as) the performance obligations are satisfied (i.e., when the customer obtains control of the good or service). The majority of our revenues are derived from product and tooling sales; however, we also receive revenues from service, license, exclusivity and royalty arrangements, which collectively are not material to the quarterly and year-to-date results. Revenue by segment and geography for the three and nine months ended September 30, 2020 and 2019 is as follows: For the Three Months Ended September 30, 2020 Segment Europe Domestic Latin Asia Total Beauty + Home 165,701 109,175 37,921 24,434 337,231 Pharma 206,376 92,932 4,846 11,604 315,758 Food + Beverage 29,688 60,439 6,668 9,369 106,164 Total 401,765 262,546 49,435 45,407 759,153 ​ For the Three Months Ended September 30, 2019 Segment Europe Domestic Latin Asia Total Beauty + Home $ 188,542 $ 75,931 $ 40,261 $ 23,448 $ 328,182 Pharma 174,252 78,259 6,366 10,374 269,251 Food + Beverage 28,718 57,307 8,058 9,762 103,845 Total $ 391,512 $ 211,497 $ 54,685 $ 43,584 $ 701,278 ​ ​ For the Nine Months Ended September 30, 2020 Segment Europe Domestic Latin Asia Total Beauty + Home $ 505,063 $ 285,369 $ 103,995 $ 67,150 $ 961,577 Pharma 598,319 264,995 18,412 32,487 914,213 Food + Beverage 86,298 172,507 21,191 24,225 304,221 Total $ 1,189,680 $ 722,871 $ 143,598 $ 123,862 $ 2,180,011 ​ ​ ​ For the Nine Months Ended September 30, 2019 Segment Europe Domestic Latin Asia Total Beauty + Home $ 607,316 $ 236,883 $ 124,352 $ 69,370 $ 1,037,921 Pharma 549,080 226,073 21,100 27,638 823,891 Food + Beverage 92,015 177,587 25,153 31,832 326,587 Total $ 1,248,411 $ 640,543 $ 170,605 $ 128,840 $ 2,188,399 ​ We perform our obligations under a contract with a customer by transferring goods and/or services in exchange for consideration from the customer. The timing of performance will sometimes differ from the timing of the receipt of the associated consideration from the customer, thus resulting in the recognition of a contract asset or a contract liability. We recognize a contract asset when we transfer control of goods or services to a customer prior to invoicing for the related performance obligation. The contract asset is transferred to accounts receivable when the product is shipped or services are performed and invoiced to the customer. We recognize a contract liability if the customer's payment of consideration precedes the entity's performance. The opening and closing balances of our contract asset and contract liabilities are as follows: ​ Balance as of December 31, 2019 Balance as of September 30, 2020 Increase/ Contract asset (current) $ 16,245 $ 15,914 $ (331) Contract asset (long-term) $ — $ — $ — Contract liability (current) $ 79,305 $ 66,782 $ (12,523) Contract liability (long-term) $ 9,779 $ 22,035 $ 12,256 ​ The differences in the opening and closing balances of our contract asset and contract liabilities are primarily the result of timing differences between our performance and the customer’s payment. The total amount of revenue recognized during the current year against contract liabilities is $59.6 million, including $39.1 million relating to contract liabilities at the beginning of the year. Determining the Transaction Price In most cases, the transaction price for each performance obligation is stated in the contract. In determining the variable amounts of consideration within the transaction price (such as volume-based customer rebates), we include an estimate of the expected amount of consideration as revenue. We apply the expected value method based on all of the information (historical, current, and forecast) that is reasonably available and identify reasonable estimates based on this information. We apply the method consistently throughout the contract when estimating the effect of an uncertainty on the amount of variable consideration to which we will be entitled. Product Sales We primarily manufacture and sell drug delivery, dispensing, sealing and active packaging solutions. The amount of consideration is typically fixed for such customers. At the time of delivery, the customer is invoiced the agreed-upon price. Revenue from product sales is typically recognized upon manufacture or shipment, when control of the goods transfers to the customer. To determine when the control transfers, we typically assess, among other things, the shipping terms of the contract, shipping being one of the indicators of transfer of control. A majority of product sales are sold free on board (“FOB”) shipping point. For FOB shipping point shipments, control of the goods transfers to the customer at the time of shipment of the goods. Therefore, our performance obligation is satisfied at the time of shipment. We have elected to account for shipping and handling costs that occur after the customer has obtained control of a good as fulfillment costs rather than as a promised service. We do not have any material significant payment terms as payment is typically received shortly after the point of sale. There also exist instances where we manufacture highly customized products that have no alternative use to us and for which we have an enforceable right to payment for performance completed to date. For these products, we transfer control and recognize revenue over time by measuring progress towards completion using the Output Method based on the number of products produced. As we normally make our products to a customer’s order, the time between production and shipment of our products is typically within a few weeks. As a part of our customary business practice, we offer a standard warranty that the products will materially comply with the technical specifications and will be free from material defects. Because such warranties are not sold separately, do not provide for any service beyond a guarantee of a product’s initial specifications, and are not required by law, there is no revenue deferral for these types of warranties. Tooling Sales We also build, or contract to build molds and other tools (collectively defined as “tooling”) necessary to produce our products. As with product sales, we recognize revenue when control of the tool transfers to the customer. If the tooling is highly customized with no alternative use to us and we have an enforceable right to payment for performance completed to date, we transfer control and recognize revenue over time by measuring progress towards completion using the Input Method based on costs incurred relative to total estimated costs to completion. Otherwise, revenue for the tooling is recognized at the point in time when the customer approves the tool. We do not have any material significant payment terms as payment is typically either received during the mold-build process or shortly after completion. In certain instances, we offer extended warranties on tools sold to our customers above and beyond the normal standard warranties. We normally receive payment at the inception of the contract and recognize revenue over the term of the contract. At December 31, 2019, $515 thousand of unearned revenue associated with outstanding contracts was reported in Accounts Payable, Accrued and Other Liabilities. At September 30, 2020, the unearned amount was $487 thousand. We expect to recognize approximately $55 thousand of the unearned amount during the remainder of 2020, $131 thousand in 2021, and $301 thousand thereafter. Credit Risk We are exposed to credit losses primarily through our product sales, tooling sales and services to our customers. We assess each customer’s ability to pay for the products we sell by conducting a credit review. The credit review considers our expected billing exposure and timing for payment and the customer’s established credit rating or our assessment of the customer’s creditworthiness based on our analysis of their financial statements when a credit rating is not available. We also consider contract terms and conditions, country and political risks, and business strategy in our evaluation. A credit limit is established for each customer based on the outcome of this review. We monitor our ongoing credit exposure through active review of customer balances against contract terms and due dates. Our activities include timely account reconciliation, dispute resolution and payment confirmation. We may employ collection agencies and legal counsel to pursue recovery of defaulted receivables. At September 30, 2020, we reported $593 million of accounts receivable, net of CECL of $7.4 million. Changes in the allowance were not material for the nine months ended September 30, 2020. Current uncertainty in credit and market conditions due to the COVID-19 pandemic may slow our collection efforts if customers experience significant difficulty accessing credit and paying their obligations, which may lead to higher than normal accounts receivable and increased CECL charges.

INCOME TAXES	INCOME TAXES The tax provision for interim periods is determined using the estimated annual effective consolidated tax rate, based on the current estimate of full-year earnings and related estimated full year-taxes, adjusted for the impact of discrete quarterly items. The effective tax rate for the three months ended September 30, 2020 and 2019, respectively, was 28.5% and 31.0% . The reported effective tax rate for the three months ended September 30, 2020 was favorably impacted by additional excess tax benefits from employee stock-based compensation of $1.4 million and benefits reflecting changes in the U.S. global intangible low taxed income ("U.S. GILTI") tax for the current year of $1.5 million. The effective tax rate for the nine months ended September 30, 2020 and 2019 was 29.4% . The nine month effective tax rates reflect a favorable impact from the excess tax benefits from employee stock-based compensation of $8.7 million and $13.6 million, respectively, offset by the unfavorable impact from losses in jurisdictions where the tax benefit is not recognized and other discrete items of $5.1 million and $10.9 million, respectively.

DERIVATIVE INSTRUMENTS AND HEDG

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIESWe maintain a foreign exchange risk management policy designed to establish a framework to protect the value of our non-functional denominated transactions from adverse changes in exchange rates. Sales of our products can be denominated in a currency different from the currency in which the related costs to produce the product are denominated. Changes in exchange rates on such inter-country sales or intercompany loans can impact our results of operations. Our policy is not to engage in speculative foreign currency hedging activities, but to minimize our net foreign currency transaction exposure, defined as firm commitments and transactions recorded and denominated in currencies other than the functional currency. We may use foreign currency forward exchange contracts, options and cross currency swaps to economically hedge these risks. For derivative instruments designated as hedges, we formally document the nature and relationships between the hedging instruments and the hedged items, as well as the risk management objectives, strategies for undertaking the various hedge transactions, and the method of assessing hedge effectiveness at inception. Quarterly thereafter, we formally assess whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the fair value or cash flows of the hedged item. Additionally, in order to designate any derivative instrument as a hedge of an anticipated transaction, the significant characteristics and expected terms of any anticipated transaction must be specifically identified, and it must be probable that the anticipated transaction will occur. All derivative financial instruments used as hedges are recorded at fair value in the Condensed Consolidated Balance Sheets. See Note 11 - Fair Value for additional details. Cash Flow Hedge For derivative instruments that are designated and qualify as cash flow hedges, the changes in fair values are recorded in accumulated other comprehensive loss and included in changes in derivative gain/loss. The changes in the fair values of derivatives designated as cash flow hedges are reclassified from accumulated other comprehensive loss to net income when the underlying hedged item is recognized in earnings. Cash flows from the settlement of derivative contracts designated as cash flow hedges offset cash flows from the underlying hedged items and are included in operating activities in the Condensed Consolidated Statements of Cash Flows. During 2017, our wholly-owned UK subsidiary borrowed $280 million in term loan borrowings under a new credit facility. In order to mitigate the currency risk of U.S. dollar debt on a euro functional currency entity and to mitigate the risk of variability in interest rates, we entered into a cross currency swap in the notional amount of $280 million to effectively hedge the foreign exchange and interest rate exposure on the $280 million term loan. This EUR/USD swap agreement fixed our U.S. dollar floating-rate debt to 1.36% euro fixed-rate debt. Related to this hedge, approximately $1.1 million of loss is included in accumulated other comprehensive loss at September 30, 2020. The amount expected to be recognized into earnings during the next 12 months related to the interest component of our cross currency swap based on prevailing foreign exchange and interest rates at September 30, 2020 is a gain of $0.1 million. The amount expected to be recognized into earnings during the next 12 months related to the foreign exchange component of our cross currency swap is dependent on fluctuations in currency exchange rates. As of September 30, 2020, the fair values of the cross currency swap were a $3.2 million liability. The swap contract expires on July 20, 2022. Hedge of Net Investments in Foreign Operations A significant number of our operations are located outside of the United States. Because of this, movements in exchange rates may have a significant impact on the translation of the financial condition and results of operations of our foreign subsidiaries. A strengthening U.S. dollar relative to foreign currencies has a dilutive translation effect on our financial condition and results of operations. Conversely, a weakening U.S. dollar has an additive effect. In some cases, we maintain debt in these subsidiaries to offset the net asset exposure. We do not otherwise actively manage this risk using derivative financial instruments. In the event we plan on a full or partial liquidation of any of our foreign subsidiaries where our net investment is likely to be monetized, we will consider hedging the currency exposure associated with such a transaction. Other As of September 30, 2020, we have recorded the fair value of foreign currency forward exchange contracts of $0.1 million in prepaid and other and $0.4 million in accounts payable, accrued and other liabilities on the balance sheet. All forward exchange contracts outstanding as of September 30, 2020 had an aggregate notional contract amount of $43.2 million. ​ Fair Value of Derivative Instruments in the Condensed Consolidated Balance Sheets as of September 30, 2020 and December 31, 2019 ​ ​ September 30, 2020 December 31, 2019 ​ Balance Sheet Location Derivatives Designated as Hedging Instruments Derivatives not Designated as Hedging Instruments Derivatives Designated as Hedging Instruments Derivatives not Designated as Hedging Instruments Derivative Assets ​ ​ ​ ​ ​ Foreign Exchange Contracts Prepaid and other $ — $ 73 — $ 206 Cross Currency Swap Contract (1) Prepaid and other — — 2,552 — ​ ​ $ — $ 73 $ 2,552 $ 206 ​ ​ ​ ​ ​ ​ Derivative Liabilities ​ ​ ​ ​ ​ Foreign Exchange Contracts Accounts payable, accrued and other liabilities $ — $ 426 $ — $ 401 Cross Currency Swap Contract (1) Accounts payable, accrued and other liabilities 3,227 — — — ​ ​ $ 3,227 $ 426 $ — $ 401 __________________________ (1) This cross currency swap contract is composed of both an interest component and a foreign exchange component. ​ ​ The Effect of Cash Flow Hedge Accounting on Accumulated Other Comprehensive Income (Loss) for the Three Months Ended September 30, 2020 and 2019 ​ Derivatives in Cash Flow Hedging Amount of Gain (Loss) Location of (Loss) Amount of Gain (Loss) Total Amount of Affected Income Statement Line Item ​ 2020 2019 ​ 2020 2019 Cross currency swap contract: ​ ​ ​ ​ ​ ​ Interest component $ (1) $ 1,586 Interest expense $ 146 $ 1,309 $ (8,851) Foreign exchange component (6,099) 6,491 Miscellaneous, net (6,099) 6,491 (1,040) ​ $ (6,100) $ 8,077 ​ $ (5,953) $ 7,800 ​ ​ The Effect of Cash Flow Hedge Accounting on Accumulated Other Comprehensive Income (Loss) for the Nine Months Ended September 30, 2020 and 2019 Derivatives in Cash Flow Hedging Amount of Gain (Loss) Location of (Loss) Amount of Gain (Loss) Total Amount of Affected Income Statement Line Item ​ 2020 2019 ​ 2020 2019 Cross currency swap contract: ​ ​ ​ ​ ​ ​ Interest component $ 2,037 $ 4,058 Interest expense $ 1,434 $ 4,315 $ (25,973) Foreign exchange component (6,379) 8,084 Miscellaneous, net (6,379) 8,084 (3,375) ​ $ (4,342) $ 12,142 ​ $ (4,945) $ 12,399 ​ ​ ​ The Effect of Derivatives Not Designated as Hedging Instruments on the Condensed Consolidated Statements of Income for the Three Months Ended September 30, 2020 and 2019 Derivatives Not Designated Location of (Loss) Gain Recognized Amount of (Loss) Gain ​ ​ 2020 2019 Foreign Exchange Contracts Other (Expense) Income: $ (994) $ (15) ​ ​ $ (994) $ (15) ​ ​ The Effect of Derivatives Not Designated as Hedging Instruments on the Condensed Consolidated Statements of Income for the Nine Months Ended September 30, 2020 and 2019 ​ Derivatives Not Designated Location of (Loss) Gain Recognized Amount of (Loss) Gain ​ ​ 2020 2019 Foreign Exchange Contracts Other (Expense) Income: $ (187) $ (529) ​ ​ $ (187) $ (529) ​ ​ ​ ​ Gross Amounts not Offset in the Statement of Financial Position ​ ​ Gross Amount Gross Amounts Offset in the Statement of Financial Position Net Amounts Presented in the Statement of Financial Position Financial Instruments Cash Collateral Received Net Amount Description ​ ​ ​ ​ ​ ​ September 30, 2020 Derivative Assets $ 73 — $ 73 — — $ 73 Total Assets $ 73 — $ 73 — — $ 73 ​ ​ ​ ​ ​ ​ ​ Derivative Liabilities $ 3,653 — $ 3,653 — — $ 3,653 Total Liabilities $ 3,653 — $ 3,653 — — $ 3,653 ​ ​ ​ ​ ​ ​ ​ December 31, 2019 Derivative Assets $ 2,758 — $ 2,758 — — $ 2,758 Total Assets $ 2,758 — $ 2,758 — — $ 2,758 ​ ​ ​ ​ ​ ​ ​ Derivative Liabilities $ 401 — $ 401 — — $ 401 Total Liabilities $ 401 — $ 401 — — $ 401

FAIR VALUE

FAIR VALUE	9 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Authoritative guidelines require the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows: • Level 1: Unadjusted quoted prices in active markets for identical assets and liabilities. • Level 2: Observable inputs other than those included in Level 1. For example, quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets. • Level 3: Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability. As of September 30, 2020, the fair values of our financial assets and liabilities were categorized as follows: ​ Total Level 1 Level 2 Level 3 Assets ​ ​ ​ ​ Foreign exchange contracts (1) $ 73 $ — $ 73 $ — Total assets at fair value $ 73 $ — $ 73 $ — Liabilities ​ ​ ​ ​ Foreign exchange contracts (1) $ 426 $ — $ 426 $ — Cross currency swap contract (1) 3,227 — 3,227 — Contingent consideration obligation 26,280 — — 26,280 Total liabilities at fair value $ 29,933 $ — $ 3,653 $ 26,280 ​ As of December 31, 2019, the fair values of our financial assets and liabilities were categorized as follows: ​ Total Level 1 Level 2 Level 3 Assets ​ ​ ​ ​ Foreign exchange contracts (1) $ 206 $ — $ 206 $ — Cross currency swap contract (1) 2,552 — 2,552 — Total assets at fair value $ 2,758 $ — $ 2,758 $ — Liabilities ​ ​ ​ ​ Foreign exchange contracts (1) $ 401 $ — $ 401 $ — Contingent consideration obligation 5,930 — — 5,930 Total liabilities at fair value $ 6,331 $ — $ 401 $ 5,930 ________________________________________________ (1) Market approach valuation technique based on observable market transactions of spot and forward rates. ​ The carrying amounts of our other current financial instruments such as cash and equivalents, accounts and notes receivable, notes payable and current maturities of long-term obligations approximate fair value due to the short-term maturity of the instruments. We consider our long-term obligations a Level 2 liability and utilize the market approach valuation technique based on interest rates that are currently available to us for issuance of debt with similar terms and maturities. The estimated fair value of our long-term obligations was $1.1 billion as of September 30, 2020 and $1.1 billion as of December 31, 2019. As discussed in Note 17 - Acquisitions, we have a contingent consideration obligation to the selling equity holders of Fusion in connection with the Fusion Acquisition (as defined herein) based on 2022 cumulative performance targets, a contingent consideration obligation to the selling equity holders of Noble in connection with the Noble Acquisition (as defined herein) based on 2024 cumulative performance targets and a contingent consideration obligation to the selling equity holder of Gateway in connection with the Gateway Acquisition (as defined herein) based on 2020 and 2022 performance targets. We consider these obligations Level 3 liabilities and have estimated the aggregate fair value for these contingent consideration arrangements to be $22.1 million and $4.2 million for the Fusion Acquisition and the Noble Acquisition, respectively, as of September 30, 2020. During the quarter ended September 30, 2020, $1.3 million of the Gateway contingent consideration accrual was paid out in full satisfaction of the remaining earn out consideration and no related liability is outstanding as all required payments have been made for both performance targets. As of December 31, 2019 the aggregate fair value for these contingent consideration arrangements was $2.9 million and $3.0 million for the Noble Acquisition and the Gateway Acquisition, respectively.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The Company, in the normal course of business, is subject to a number of lawsuits and claims both actual and potential in nature. While management believes the resolution of these claims and lawsuits will not have a material adverse effect on our financial position, results of operations or cash flows, claims and legal proceedings are subject to inherent uncertainties, and unfavorable outcomes could occur and could include amounts in excess of any accruals which management has established. Were such unfavorable final outcomes to occur, it is possible that they could have a material adverse effect on our financial position, results of operations and cash flows. Under our Certificate of Incorporation, we have agreed to indemnify our officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have a directors and officers liability insurance policy that covers a portion of our exposure. As a result of our insurance policy coverage, we believe the estimated fair value of these indemnification agreements is minimal. We have no liabilities recorded for these agreements as of September 30, 2020 and December 31, 2019. A fire caused damage to our facility in Annecy, France in June 2016. We are insured for the damages caused by the fire, including business interruption insurance. For the nine months ended September 30, 2020, we did not receive any insurance proceeds, and have no insurance receivable as of September 30, 2020. During the nine months ended September 30, 2020 and 2019, profitability was not impacted. The final settlement continues to be negotiated. In many cases, our insurance coverage exceeds the amount of our recognized losses. However, no gain contingencies were recognized during the nine months ended September 30, 2020 as our ability to realize those gains remains uncertain. An environmental investigation, undertaken to assess areas of possible contamination, was completed at our facility in Jundiaí, São Paulo, Brazil. The facility is primarily an internal supplier of anodized aluminum components for certain of our dispensing systems. The testing indicated that soil and groundwater in certain areas of the facility were impacted above acceptable levels established by local regulations. In March 2017, we reported the findings to the relevant environmental authority, the Environmental Company of the State of São Paulo – CETESB. Based upon our best estimate, we recorded a reserve of $1.5 million (operating expense) in the first quarter of 2017 related to this contingency. During 2019, we paid approximately $0.6 million. For the nine months ended September 30, 2020, we paid approximately $0.1 million. As of September 30, 2020, our outstanding reserve is $0.4 million. The ultimate loss associated with this environmental contingency is subject to the investigation and ongoing review of the CETESB. We will continue to evaluate the range of likely costs as the investigation proceeds and we have further clarity on the nature and extent of remediation that will be required. We note that the contamination, or any failure to complete any required remediation in a timely manner, could potentially result in fines or penalties. In March 2017, the Supreme Court of Brazil issued a decision that a certain state value added tax should not be included in the calculation of federal gross receipts taxes. The decision reduces our gross receipts tax in Brazil prospectively and, potentially, retrospectively. During the first quarter of 2019, we received a favorable court decision of $2.7 million for the retrospective right to recover part of our claim. This amount is recorded in cost of sales as a favorable impact of $1.7 million and $1.0 million was recognized as interest income. In June 2020, we received a favorable court decision of $0.7 million for the retrospective right to recover part of our claim. This amount is recorded in cost of sales as a favorable impact of $0.7 million. If the Supreme Court grants full retrospective recovery, we estimate remaining potential recoveries of approximately $1.5 million to $7.5 million, including interest, depending on the future decisions of the Supreme Court of Brazil. Due to uncertainties around our remaining court recovery claims, we have not recorded any further amounts relating to the retrospective nature of this matter. In December 2019, tax authorities in Brazil notified us of a tax assessment of approximately $6.1 million, including interest and penalties of $2.3 million and $0.8 million, respectively, relating to differences in tax classification codes used for import duties for the period from January 2015 to August 2018. We are vigorously contesting the assessment, including interest and penalties, and have filed an administrative defense appeal in December 2019. In June 2020, an unfavorable decision was issued on the first administrative defense appeal. We filed a second administrative defense appeal in August 2020. We still believe we have a strong defense. Due to uncertainty in the amount of assessment and the timing of our appeal, no liability is recorded as of September 30, 2020.

Equity [Abstract]
STOCK REPURCHASE PROGRAM	STOCK REPURCHASE PROGRAM On April 18, 2019, we announced a share repurchase authorization of up to $350 million of common stock. This authorization replaces previous authorizations and has no expiration date. We may repurchase shares through the open market, privately negotiated transactions or other programs, subject to market conditions. During the three and nine months ended September 30, 2020, we did not repurchase any shares. During the three and nine months ended September 30, 2019, we repurchased approximately 300 thousand shares and 493 thousand shares for approximately $35.8 million and $54.9 million, respectively. As of September 30, 2020, there was $278.5 million of authorized share repurchases available to us.

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION	9 Months Ended

Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION We issue restricted stock units (“RSUs”), which consist of time-based and performance-based awards, to employees under stock awards plans approved by stockholders. In addition, RSUs are issued to non-employee directors under a Restricted Stock Unit Award Agreement for Directors pursuant to the Company’s 2018 Equity Incentive Plan. RSUs granted to employees vest according to a specified performance period and/or vesting period. Time-based RSUs generally vest over three years. Performance-based RSUs vest at the end of the specified performance period, generally three years, assuming required performance or market vesting conditions are met. Performance-based RSUs have one of two vesting conditions: (1) based on our internal financial performance metrics and (2) based on our total shareholder return (“TSR”) relative to total shareholder returns of an industrial peer group. At the time of vesting, the vested shares of common stock are issued in the employee’s name. In addition, RSU awards are generally net settled (shares are withheld to cover the employee tax obligation). RSUs granted to directors are only time-based and generally vest over one year. The fair value of both time-based RSUs and performance-based RSUs pertaining to internal performance metrics is determined using the closing price of our common stock on the grant date. The fair value of performance-based RSUs pertaining to TSR is estimated using a Monte Carlo simulation. Inputs and assumptions used to calculate the fair value are shown in the table below. The fair value of these RSUs is expensed over the vesting period using the straight-line method or using the graded vesting method when an employee becomes eligible to retain the award at retirement. ​ Nine Months Ended September 30, 2020 2019 Fair value per stock award $ 94.98 $ 134.97 Grant date stock price $ 83.93 $ 104.51 Assumptions: ​ ​ Aptar's stock price expected volatility 23.80 % 16.50 % Expected average volatility of peer companies 48.50 % 31.90 % Correlation assumption 63.50 % 37.40 % Risk-free interest rate 0.31 % 2.19 % Dividend yield assumption 1.72 % 1.30 % ​ A summary of RSU activity as of September 30, 2020 and changes during the nine month period then ended is presented below: ​ Time-Based RSUs Performance-Based RSUs ​ Units Weighted Average Units Weighted Average Nonvested at January 1, 2020 480,729 $ 95.45 181,680 $ 117.26 Granted 232,802 86.05 417,313 93.08 Vested (130,654) 85.62 — — Forfeited (5,692) 99.08 (6,714) 108.10 Nonvested at September 30, 2020 577,185 $ 92.33 592,279 $ 100.29 ​ Included in the September 30, 2020 time-based RSUs are 12,379 units granted to non-employee directors and 11,490 units vested related to non-employee directors. Compensation expense recorded attributable to RSUs for the first nine months of 2020 and 2019 was approximately $24.5 million and $13.7 million, respectively. The actual tax benefit realized for the tax deduction from RSUs was approximately $4.5 million in the nine months ended September 30, 2020. The fair value of units vested during the nine months ended September 30, 2020 and 2019 was $11.2 million and $4.1 million, respectively. The intrinsic value of units vested during the nine months ended September 30, 2020 and 2019 was $13.5 million and $4.9 million, respectively. As of September 30, 2020, there was $51.1 million of total unrecognized compensation cost relating to RSU awards which is expected to be recognized over a weighted-average period of 2.0 years. Historically we issued stock options to our employees and non-employee directors. Beginning in 2019, we no longer issue stock options. Stock options were awarded with the exercise price equal to the market price on the date of grant and generally vest over three years and expire 10 years after grant. Compensation expense attributable to employee stock options for the first nine months of 2020 was approximately $1.7 million ($1.3 million after tax). Approximately $1.4 million of the compensation expense was recorded in selling, research & development and administrative expenses and the balance was recorded in cost of sales. Compensation expense attributable to stock options for the first nine months of 2019 was approximately $4.4 million ($3.6 million after tax). Approximately $3.7 million of the compensation expense was recorded in selling, research & development and administrative expenses and the balance was recorded in cost of sales. The reduction in stock option expense is due to our move to RSUs as discussed above. For stock option grants, we used historical data to estimate expected life and volatility. A summary of option activity under our stock plans during the nine months ended September 30, 2020 is presented below:​ ​ Stock Awards Plans Director Stock Option Plans ​ Options Weighted Average Options Weighted Average Outstanding, January 1, 2020 5,044,180 $ 68.32 135,251 $ 58.45 Granted — — — — Exercised (785,478) 59.98 (34,151) 51.75 Forfeited or expired (14,200) 76.07 — — Outstanding at September 30, 2020 4,244,502 $ 69.91 101,100 $ 60.71 Exercisable at September 30, 2020 4,089,846 $ 69.11 101,100 $ 60.71 Weighted-Average Remaining Contractual Term (Years): ​ ​ ​ ​ Outstanding at September 30, 2020 4.9 ​ 2.9 ​ Exercisable at September 30, 2020 4.8 ​ 2.9 ​ Aggregate Intrinsic Value: ​ ​ ​ ​ Outstanding at September 30, 2020 $ 183,753 ​ $ 5,306 ​ Exercisable at September 30, 2020 $ 179,771 ​ $ 5,306 ​ Intrinsic Value of Options Exercised During the Nine Months Ended: ​ ​ ​ ​ September 30, 2020 $ 44,086 ​ $ 2,183 ​ September 30, 2019 $ 76,797 ​ $ 722 ​ ​ The grant date fair value of options vested during the nine months ended September 30, 2020 and 2019 was $7.6 million and $12.2 million, respectively.

EARNINGS PER SHARE

EARNINGS PER SHARE	9 Months Ended
	Sep. 30, 2020
Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE Basic net income per share is calculated by dividing net income attributable to Aptar by the weighted-average number of common shares outstanding during the period. Diluted net income per share is calculated by dividing the net income attributable to Aptar by the weighted-average number of common and common equivalent shares outstanding during the applicable period. The difference between basic and diluted earnings per share is attributable to stock-based compensation awards. Stock-based compensation awards for which total employee proceeds exceed the average market price over the applicable period would have an antidilutive effect on earnings per share, and accordingly, are excluded from the calculation of diluted earnings per share. The reconciliation of basic and diluted earnings per share for the three and nine months ended September 30, 2020 and 2019 is as follows: ​ ​ ​ Three Months Ended ​ September 30, 2020 September 30, 2019 ​ Diluted Basic Diluted Basic Consolidated operations ​ ​ ​ ​ Income available to common stockholders $ 63,716 $ 63,716 $ 56,750 $ 56,750 ​ ​ ​ ​ ​ Average equivalent shares ​ ​ ​ ​ Shares of common stock 64,562 64,562 64,010 64,010 Effect of dilutive stock-based compensation ​ ​ ​ ​ Stock options 1,809 — 2,367 — Restricted stock 551 — 325 — Total average equivalent shares 66,922 64,562 66,702 64,010 Net income per share $ 0.95 $ 0.99 $ 0.85 $ 0.89 ​ ​ Nine Months Ended ​ September 30, 2020 September 30, 2019 ​ Diluted Basic Diluted Basic Consolidated operations ​ ​ ​ ​ Income available to common stockholders $ 160,808 $ 160,808 $ 193,669 $ 193,669 ​ ​ ​ ​ ​ Average equivalent shares ​ ​ ​ ​ Shares of common stock 64,278 64,278 63,485 63,485 Effect of dilutive stock-based compensation ​ ​ ​ ​ Stock options 1,770 — 2,425 — Restricted stock 435 — 253 — Total average equivalent shares 66,483 64,278 66,163 63,485 Net income per share $ 2.42 $ 2.50 $ 2.93 $ 3.05

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION We are organized into three reporting segments. Our Beauty + Home segment sells to the personal care, beauty and home care markets. Our Pharma segment serves customers in the prescription drug, consumer health care, injectables and active packaging markets. Our Food + Beverage segment sells to the food and beverage markets. The accounting policies of the segments are the same as those described in Part II, Item 8, Note 1 - Summary of Significant Accounting Policies in our Annual Report on Form 10-K for the year ended December 31, 2019. We evaluate performance of our business units and allocate resources based upon Adjusted EBITDA.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS Business Combinations On April 1, 2020, we completed our acquisition (the “Fusion Acquisition”) of 100% of the equity interests of Fusion Packaging, Inc. (“Fusion”) for a purchase price of approximately $163.8 million (net of $1.0 million of cash acquired), which was funded by a draw on our revolving credit facility and cash on hand. Fusion, based in Dallas, TX, is a global leader in the design, engineering and distribution of luxury packaging for the beauty industry. As part of the Fusion Acquisition, we are also obligated to pay to the selling equity holders of Fusion certain contingent consideration based on 2022 cumulative financial performance metrics as defined in the purchase agreement. Based on a projection as of the acquisition date, we estimated the aggregate fair value for this contingent consideration arrangement to be $19.1 million utilizing a Black-Scholes valuation model. As of September 30, 2020, we have estimated the aggregate fair value for this contingent consideration arrangement to be $22.1 million. As of the acquisition date, $2.8 million was held in restricted cash pending the finalization of a working capital adjustment and indemnity escrow. During the third quarter of 2020, $2.0 million related to the working capital escrow was released from restriction, resulting in a refund from seller of $294 thousand and a corresponding decrease to our purchase price and associated goodwill balance. Fusion contributed net sales of $37.9 million and pretax loss of $1.5 million since acquisition for the period ended September 30, 2020 which have been included in the Condensed Consolidated Financial Statements within our Beauty + Home segment. Included in pretax loss is $5.7 million of fair value adjustment amortization for inventory sold during 2020 and contingent consideration liability adjustments. On October 31, 2019, we completed our acquisition (the “Noble Acquisition”) of 100% of the equity interests of Noble International Holdings, Inc., Genia Medical, Inc. and JBCB Holdings, LLC (collectively referred to as “Noble”). Noble, based in Orlando, FL, is a leading provider in developing patient-centric advanced drug delivery system training devices including autoinjector, prefilled syringe, onbody and respiratory devices for the world’s leading biopharmaceutical companies and original equipment manufacturers. The purchase price was approximately $62.3 million (net of $1.6 million of cash acquired) and was funded by cash on hand. As part of the Noble Acquisition, we are also obligated to pay to the selling equity holders of Noble certain contingent consideration based on 2024 cumulative financial performance metrics defined in the purchase agreement. Based on projection as of the acquisition date, we estimated the aggregate fair value for this contingent consideration arrangement to be $2.9 million utilizing the Black-Scholes valuation model. As of September 30, 2020, we have estimated the aggregate fair value for this contingent consideration arrangement to be $4.2 million. As of December 31, 2019, $5 million was held in restricted cash pending the finalization of a working capital adjustment and indemnity escrow. During the first quarter of 2020, $1.0 million related to the working capital escrow was released from restriction, resulting in an additional $463 thousand payment due to the seller and a corresponding increase to our purchase price and associated goodwill balance. The results of Noble’s operations have been included in the Condensed Consolidated Financial Statements within our Pharma segment since the date of acquisition. On June 5, 2019, we completed our acquisition (the “Nanopharm Acquisition”) of all of the outstanding capital stock of Nanopharm Ltd. (“Nanopharm”). Nanopharm, located in Newport, UK, is a science-driven, leading provider of orally inhaled and nasal drug product design and development services. The purchase price was approximately $38.1 million (net of $1.8 million of cash acquired) and was funded by cash on hand. The results of Nanopharm’s operations have been included in the Condensed Consolidated Financial Statements within our Pharma segment since the date of acquisition. On May 31, 2019, we completed our acquisition (the “Gateway Acquisition”) of all of the outstanding equity interests of Gateway Analytical LLC (“Gateway”). Gateway, located in Gibsonia, PA, provides industry-leading particulate detection and predictive analytical services to customers developing injectable medicines. The purchase price was approximately $7.0 million and was funded by cash on hand. As part of the Gateway Acquisition, we are also obligated to pay to the selling equity holder of Gateway certain contingent consideration based on 2020 and 2022 performance targets defined in the purchase agreement. Based on projections as of the acquisition date, we estimated the aggregate fair value for this contingent consideration arrangement to be $3.0 million. During the second quarter 2020, $1.5 million of the contingent consideration accrual was paid as a result of the business meeting their first performance target. During the third quarter 2020, an additional $1.3 million was paid out in full satisfaction of the remaining earn out consideration and a gain of $235 thousand was realized. The results of Gateway’s operations have been included in the Condensed Consolidated Financial Statements within our Pharma segment since the date of acquisition. The following table summarizes the assets acquired and liabilities assumed as of the acquisition date at estimated fair value. ​ 2020 2019 Assets ​ ​ Cash and equivalents $ 1,010 $ 3,427 Accounts receivable 4,380 3,504 Inventories 386 — Prepaid and other 1,090 2,478 Property, plant and equipment 2,885 4,267 Goodwill 99,644 59,143 Intangible assets 79,900 52,980 Operating lease right-of-use assets 4,744 — Other miscellaneous assets 65 430 Liabilities ​ ​ Accounts payable, accrued and other liabilities 5,641 5,388 Deferred income taxes — 2,592 Operating lease liabilities 4,207 — Deferred and other non-current liabilities 322 1,598 Net assets acquired $ 183,934 $ 116,651 ​ The following table is a summary of the fair value estimates of the acquired identifiable intangible assets and weighted-average useful lives as of the acquisition date: ​ 2020 2019 ​ Weighted-Average Useful Life (in Years) Estimated Fair Value of Assets Weighted-Average Useful Life (in Years) Estimated Fair Value of Assets Acquired technology 4 $ 4,600 8 $ 9,160 Customer relationships 13 62,300 11 39,379 Trademarks and trade names 4 10,300 4 2,457 License agreements and other 0.25 2,700 1 1,984 Total ​ $ 79,900 ​ $ 52,980 ​ Goodwill in the amount of $99.6 million was recorded related to the Fusion Acquisition which is included in the Beauty + Home segment and $59.1 million was recorded related to the 2019 acquisitions, all of which are included in the Pharma segment. Goodwill is calculated as the excess of the consideration transferred over the net assets acquired and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Goodwill largely consists of unique relationships, brand equity and proprietary technology that has been established creating niches such as turnkey solutions for the beauty market related to the Fusion Acquisition, analytical services for drug developers related to the Nanopharm Acquisition and Gateway Acquisition and patient onboarding related to the Noble Acquisition, as well as the abilities of the acquired companies to maintain their competitive advantage from a technical viewpoint. Goodwill will not be amortized, but will be tested for impairment at least annually. For the Fusion Acquisition, goodwill of $82.3 million will be deductible for tax purposes. For the 2019 acquisitions, goodwill of $31.1 million will be deductible for tax purposes. The unaudited pro forma results presented below include the effects of the Fusion Acquisition as if it had occurred as of January 1, 2019. The unaudited pro forma results reflect certain adjustments related to the acquisition, such as intangible asset amortization, fair value adjustments for inventory and financing costs related to the change in our debt structure. The pro forma results do not include any synergies or other expected benefits of the acquisition. Accordingly, the unaudited pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the acquisition been completed on the date indicated. ​ ​ Three Months Ended September 30, 2020 Nine Months Ended ​ 2020 2019 2020 2019 Net Sales $ 759,153 $ 719,008 $ 2,187,974 $ 2,244,834 Net Income Attributable to AptarGroup Inc. 63,724 57,191 160,077 196,195 Net Income per common share — basic 0.99 0.89 2.49 3.09 Net Income per common share — diluted 0.95 0.86 2.41 2.97 ​ Asset Acquisition On August 2, 2019, we completed our asset acquisition (the “Bapco Acquisition”) of the remaining 80% ownership interest in the capital stock of Bapco Closures Holdings Limited (“Bapco”), for $3.8 million (net of $2.9 million of cash acquired). The 20% ownership investment previously held in Bapco is now included within the intangible assets acquired. Bapco, located in Leeds, UK, provides innovative closures sealing technology that provides package integrity and tamper evidence. The results of Bapco’s operations have been included in the Condensed Consolidated Financial Statements within our Food + Beverage segment since the date of acquisition.

Equity Method Investments and Joint Ventures [Abstract]
INVESTMENT IN EQUITY SECURITIES	INVESTMENT IN EQUITY SECURITIES Our investment in equity securities consisted of the following: ​ ​ September 30, December 31, Equity Method Investments: ​ ​ BTY $ 31,921 $ 119 Sonmol 5,195 — Kali Care 3,611 3,881 Desotec GmbH 904 858 ​ Other Investments 5,365 3,538 ​ $ 46,995 $ 8,396 ​ Equity method investments Sonmol On April 1, 2020, we invested $5 million to acquire 30% of the equity interests in Healthcare, Inc., Shanghai Sonmol Internet Technology Co., Ltd. and its subsidiary, Shanghai Sonmol Medical Equipment Co., Ltd. (collectively referred to as “Sonmol”), a pharmaceutical and leading Chinese digital respiratory therapeutics company that provides connected devices for asthma control and develops digital therapies and services platforms targeting chronic respiratory illnesses and other diseases. BTY On January 1, 2020, we acquired 49% of the equity interests in 3 related companies: Suzhou Hsing Kwang, Suqian Hsing Kwang and Suzhou BTY (collectively referred to as “BTY”) for an approximate purchase price of $32 million. We have a call option to acquire an additional 26% to 31% of BTY’s equity interests following the initial lock-up period of 5 years based on a predetermined formula. Subsequent to the second lock-up period, which ends 3 years subsequent to the initial lock-up period, we have a call option to acquire the remaining equity interests of BTY based on a predetermined formula. Additionally, the selling shareholders of BTY have a put option for the remaining equity interest to be acquired by Aptar based on a predetermined formula. The BTY entities are leading Chinese manufacturers of high quality, decorative metal components, metal-plastic sub-assemblies, and complete color cosmetics packaging solutions for the beauty industry. Kali Care During 2017, we invested $5 million to acquire 20% of the equity interests in Kali Care, a technology company that provides digital monitoring systems for medical devices. Desotec GmbH During 2009, we invested €574 thousand to acquire 23% of the equity interests in Desotec GmbH, a leading manufacturer of special assembly machines for bulk processing for the pharmaceutical, beauty and home and food and beverages markets. Other investments During August 2019, we invested an aggregate amount of $3.5 million in two preferred equity investments in sustainability companies Loop and Purecycle Technologies (“Purecycle”) that are accounted for at cost less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer. In July and September 2020, we invested an additional $1.3 million in these two equity investments and also received $333 thousand of equity in Purecycle in exchange for our resource dedication for technological partnership and support. There were no indications of impairment nor were there any changes from observable price changes noted in the nine months ended September 30, 2020 related to these investments.

Restructuring and Related Activities [Abstract]
RESTRUCTURING INITIATIVES	RESTRUCTURING INITIATIVES In late 2017, we began a business transformation to drive profitable sales growth, increase operational excellence, enhance our approach to innovation and improve organizational effectiveness. The primary focus of the plan is the Beauty + Home segment; however, certain global general and administrative functions are also being addressed. For the three and nine months ended September 30, 2020, we recognized $3.4 million and $15.6 million of restructuring costs related to this plan, respectively. For the three and nine months ended September 30, 2019, we recognized $6.0 million and $17.3 million of restructuring costs related to this plan, respectively. Using current exchange rates, we estimate total implementation costs of approximately $125 million for these initiatives, including costs that have been recognized to date. The cumulative expense incurred as of September 30, 2020 was $102.1 million. We also anticipate making capital investments related to the transformation plan of approximately $50 million, of which $47 million has been incurred to date. As of September 30, 2020 we have recorded the following activity associated with the business transformation: ​ Beginning Net Charges for the Nine Months Ended 9/30/2020 Cash Paid Interest and Ending Reserve at 9/30/2020 Employee severance $ 7,090 $ 10,210 $ (6,157) $ 161 $ 11,304 Professional fees and other costs 3,609 5,375 (5,359) 4 3,629 Totals $ 10,699 $ 15,585 $ (11,516) $ 165 $ 14,933

Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION ​ The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of AptarGroup, Inc. and our subsidiaries. The terms “AptarGroup”, “Aptar”, “Company”, “we”, “us” or “our” as used herein refer to AptarGroup, Inc. and our subsidiaries. All significant intercompany accounts and transactions have been eliminated. Certain previously reported amounts have been reclassified to conform to the current period presentation. In the opinion of management, the unaudited Condensed Consolidated Financial Statements (the “Condensed Consolidated Financial Statements”) include all normal recurring adjustments necessary for a fair statement of consolidated financial position, results of operations, comprehensive income, changes in equity and cash flows for the interim periods presented. The accompanying Condensed Consolidated Financial Statements have been prepared by the Company, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations, although we believe that the disclosures made are adequate to make the information presented not misleading. Also, certain financial position data included herein was derived from the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 but does not include all disclosures required by U.S. GAAP. Accordingly, these Condensed Consolidated Financial Statements and related notes should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2019. The results of operations of any interim period are not necessarily indicative of the results that may be expected for the year. Beginning July 1, 2018, we have applied highly inflationary accounting for our Argentinian subsidiaries pursuant to U.S. GAAP. We have changed the functional currency from the Argentinian peso to the U.S. dollar. We remeasure our peso denominated assets and liabilities using the official rate. In September 2019, the President of Argentina reinstituted exchange controls restricting foreign currency purchases in an attempt to stabilize Argentina’s financial markets. As a result of these currency controls, a legal mechanism known as the Blue Chip Swap emerged in Argentina for reporting entities to transfer U.S. dollars. The Blue Chip Swap rate has diverged significantly from Argentina’s “official rate” due to the economic environment. During the second quarter of 2020, we transferred U.S. dollars into Argentina through the Blue Chip Swap method and we recognized a gain of $1.0 million. This gain helped to offset foreign currency losses due to our Argentinian peso exposure and devaluation against the U.S. dollar. For the nine months ended September 30, 2020, our Argentinian operations contributed less than 2.0% of consolidated net assets and revenues. There are many uncertainties regarding the current COVID-19 pandemic, including the scope of scientific and health issues, the anticipated duration of the pandemic and the extent of local and worldwide social, political and economic disruption it may cause. The pandemic has impacted certain markets within our business, operations and financial results during the nine months ended September 30, 2020 including an overall reduction to net sales within those markets. No impairments were recorded as of September 30, 2020. While the disruption is currently expected to be temporary, there is uncertainty around the duration. Due to significant uncertainty surrounding the situation, future results could change and therefore our results could be materially impacted.
ADOPTION OF RECENT ACCOUNTING PRONOUNCEMENTS	ADOPTION OF RECENT ACCOUNTING STANDARDS ​ Changes to U.S. GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Updates (“ASUs”) to the FASB’s Accounting Standards Codification. Effective January 1, 2020, we adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, issued by the FASB in June 2016, as well as the clarifying amendments subsequently issued. We applied the guidance using a modified retrospective approach and accordingly recognized an amount of $1.4 million as the cumulative adjustment to opening retained earnings in the first quarter of 2020. This is based on management's best estimates of specific losses on individual exposures particularly on current trade receivables, as well as the time value of money and reasonable and supportable information that is available at the reporting date about past events, current conditions and forecasts of future economic conditions. On an ongoing basis, we will contemplate forward-looking economic conditions in recording lifetime expected credit losses for our financial assets measured at cost, such as our trade receivables and certain other assets. In January 2017, the FASB issued ASU 2017-04, which provides guidance to simplify how an entity is required to test goodwill for impairm ent by eliminating Step 2 from the goodwill impairment test. As a result, impairment charges are required for the amount by which a reporting unit’s carrying amount exceeds its fair value up to the amount of its allocated goodwill. We adopted the standard on January 1, 2020 and did not record any impairment charges. In August 2018, the FASB issued ASU 2018-15 to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement) by providing guidance for determining when the arrangement includes a software license. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the amendments require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The amendments also require the entity (customer) to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. We adopted the standard on January 1, 2020 and no material impacts were noted. In August 2018, the FASB issued ASU 2018-13, which amends disclosure requirements for fair value measurements. The new standard modifies disclosure requirements including removing requirements to disclose the valuation process for Level 3 measurements and adding requirements to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 measurements. We adopted the standard on January 1, 2020 and no material impacts were noted. Other accounting standards that have been issued by the FASB or other standards-setting bodies did not have a material impact on our Condensed Consolidated Financial Statements.
INCOME TAXES	INCOME TAXES ​ We compute taxes on income in accordance with the tax rules and regulations of the many taxing authorities where the income is earned. The income tax rates imposed by these taxing authorities may vary substantially. Taxable income may differ from pre-tax income for financial accounting purposes. To the extent that these differences create temporary differences between the tax basis of an asset or liability and our reported amount in the financial statements, an appropriate provision for deferred income taxes is made. We maintain our assertion that the cash and distributable reserves at our non-U.S. affiliates are indefinitely reinvested. Under current U.S. tax laws, all of our non-U.S. earnings are subject to U.S. taxation. We will provide for the necessary withholding and local income taxes when management decides that an affiliate should make a distribution. These decisions are made taking into consideration the financial requirements of the non-U.S. affiliates and the global cash management goals of the Company. We provide a liability for the amount of unrecognized tax benefits from uncertain tax positions. This liability is provided whenever we determine that a tax benefit will not meet a more-likely-than-not threshold for recognition. The Company is subject to taxation and files income tax returns in the U.S. federal jurisdiction and many state and foreign jurisdictions. The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner inconsistent with its expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. The resolution of each of these audits is not expected to be material to our Condensed Consolidated Financial Statements.
