Significant Accounting Policies [Text Block]	( 1 Summary of Significant Accounting Policies UFP Technologies, Inc. (“the Company”) is an innovative designer and custom converter of foams, plastics, composites and natural fiber products principally serving the medical, automotive, aerospace and defense, consumer, electronics and industrial markets. The Company was incorporated in the State of Delaware in 1993. (a) Principles of Consolidation The consolidated financial statements include the accounts and results of operations of UFP Technologies, Inc., its wholly-owned subsidiaries, Moulded Fibre Technology, Inc., Simco Industries, Inc. Dielectrics, Inc. and Stephenson & Lawyer, Inc. and its wholly-owned subsidiary, Patterson Properties Corporation. All significant intercompany balances and transactions have been eliminated in consolidation. The Company has evaluated all subsequent events through the date of this filing. (b) Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, including allowance for doubtful accounts and the net realizable value of inventory, and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (c) Fair Value Measurement The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value for assets and liabilities, which are required to be recorded at fair value, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurement or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions, and credit risk. The Company has not (d) Fair Value of Financial Instruments Cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other liabilities are stated at carrying amounts that approximate fair value because of the short maturity of those instruments. The carrying amount of the Company’s long-term debt approximates fair value as the interest rate on the debt approximates the Company’s current incremental borrowing rate. (e) Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three December 31, 2018 not December 31, 2017, The Company maintains its cash in bank deposit accounts, money market funds, and certificates of deposit that at times exceed federally insured limits. The Company periodically reviews the financial stability of institutions holding its accounts and does not December 31, 2018, $3.8 (f) Accounts Receivable The Company periodically reviews the collectability of its accounts receivable. Provisions are recorded for accounts that are potentially uncollectable. Determining adequate reserves for accounts receivable requires management’s judgment. Conditions impacting the realizability of the Company’s receivables could cause actual asset write-offs to be materially different than the reserved balances as of December 31, 2018. (g) Inventories Inventories include material, labor, and manufacturing overhead and are valued at the lower of cost or net realizable value. Cost is determined using the first first The Company periodically reviews the realizability of its inventory for potential excess or obsolescence. Determining the net realizable value of inventory requires management’s judgment. Conditions impacting the realizability of the Company’s inventory could cause actual asset write-offs to be materially different than the Company’s current estimates as of December 31, 2018. (h) Property, Plant, and Equipment Property, plant, and equipment are stated at cost and are depreciated or amortized using the straight-line method over the estimated useful lives of the assets or the related lease term, if shorter. Estimated useful lives of property, plant, and equipment are as follows: Leasehold improvements Shorter of estimated useful life or remaining lease term Buildings and improvements (in years) 20 - 40 Machinery & Equipment 7 - 15 Furniture, fixtures, computers & software 3 - 7 Property, plant, and equipment amounts are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not No December 31, 2018 (i) Goodwill Goodwill is tested for impairment annually and will be tested for impairment between annual tests if an event occurs or circumstances change that would indicate that the carrying amount may one December 31, 2018, one · The reporting unit’s estimated financials and five · The projected terminal value which reflects the total present value of projected cash flows beyond the last period in the DCF. This value reflects a growth rate for the reporting unit, which is approximately the same growth rate of expected inflation into perpetuity. · The discount rate determined using a Weighted Average Cost of Capital method (“WACC”), which considered market and industry data as well as Company-specific risk factors. · Selection of guideline public companies which are similar in size and market capitalization to each other and to the Company.

Forfeitures are expensed as they occur. The Company issues share-based awards through several plans that are described in detail in Note 12. Years Ended December 31, 2018 2017 2016 Share-based compensation expense $ 1,212 $ 1,068 $ 1,056 The compensation expense for stock options granted during the three December 31, 2018, Years Ended December 31, 2018 2017 2016 Expected volatility 27.7 % 27.4% - 29.1% 29.7 % Expected dividends None None None Risk-free interest rate 2.7 % 1.56% - 1.84% 0.9 % Exercise price $ 31.20 $27.05 – $28.70 $ 22.02 Expected term (in years) 6.0 2.7 to 5.8 5.0 Weighted-average grant-date fair value $ 10.15 5.59 - $8.51 $ 6.11 The stock volatility for each grant is determined based on a review of the experience of the weighted average of historical daily price changes of the Company’s common stock over the expected option term, and the risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected term of the option. The expected term is estimated based on historical option exercise activity. The total income tax benefit recognized in the consolidated statements of income for share-based compensation arrangements was approximately $544,000, $525,000 $318,000 December 31, 2018, 2017 2016, (m) Deferred Rent The Company accounts for escalating rental payments on a straight-line basis over the term of the lease.

(o) Income Taxes The Company’s income taxes are accounted for under the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax expense or benefit results from the net change during the year in deferred tax assets and liabilities.

Fair Value Disclosures [Text Block]	( 17 Fair Value of Financial Instruments Financial instruments recorded at fair value in the consolidated balance sheets, or disclosed at fair value in the footnotes, are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels defined by ASC 820, Fair Value Measurements and Disclosures Level 1 Valued based on unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 Valued based on either directly or indirectly observable prices for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Level 3 Valued based on management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. The following table presents the fair value and hierarchy levels, for financial assets that are measured at fair value on a recurring basis (in thousands): Level 2 December 31, Assets: Derivative financial instruments $ 64 Derivative financial instruments consist of an interest rate swap for which fair value is determined through the use of a pricing model that utilizes verifiable inputs such as market interest rates that are observable at commonly quoted intervals for the full term of the swap agreement. The Company has financial instruments, such as accounts receivable, accounts payable, and accrued expenses, that are stated at carrying amounts that approximate fair value because of the short maturity of those instruments. The carrying amount of the Company’s long-term debt approximates fair value as the interest rate on the debt approximates the estimated borrowing rate currently available to the Company.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	(a) Principles of Consolidation The consolidated financial statements include the accounts and results of operations of UFP Technologies, Inc., its wholly-owned subsidiaries, Moulded Fibre Technology, Inc., Simco Industries, Inc. Dielectrics, Inc. and Stephenson & Lawyer, Inc. and its wholly-owned subsidiary, Patterson Properties Corporation. All significant intercompany balances and transactions have been eliminated in consolidation. The Company has evaluated all subsequent events through the date of this filing.
Use of Estimates, Policy [Policy Text Block]	(b) Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, including allowance for doubtful accounts and the net realizable value of inventory, and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value Measurement, Policy [Policy Text Block]	(c) Fair Value Measurement The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value for assets and liabilities, which are required to be recorded at fair value, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurement or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions, and credit risk. The Company has not

The carrying amount of the Company’s long-term debt approximates fair value as the interest rate on the debt approximates the Company’s current incremental borrowing rate.

Trade and Other Accounts Receivable, Policy [Policy Text Block]	(f) Accounts Receivable The Company periodically reviews the collectability of its accounts receivable. Provisions are recorded for accounts that are potentially uncollectable. Determining adequate reserves for accounts receivable requires management’s judgment.
