Notes to Financial Statements
Nature of Operations [Text Block]	1. The Company Alpha Pro Tech, Ltd. (“Alpha Pro Tech” or the “Company”) is in the business of protecting people, products and environments. The Company accomplishes this by developing, manufacturing and marketing a line of building supply products for the new home and re-roofing markets; a line of disposable protective apparel for the cleanroom, the industrial markets and the pharmaceutical markets; and a line of infection control products for the medical and dental markets. The Building Supply segment consists of construction weatherization products, such as housewrap and synthetic roof underlayment, as well as other woven material. The Disposable Protective Apparel segment consists of a complete line of disposable protective garments (shoecovers, bouffant caps, coveralls, gowns, frocks and lab coats), face masks and face shields. Previously, face masks and face shields were included in a separate business segment called Infection Control. All of our disposable protective apparel products, including face masks and face shields, are sold through similar distribution channels, are single-use and disposable, have the purpose of protecting people, products and environments, and have to be produced in Food and Drug Administration (“FDA”) approved facilities, regardless of the market served. Based on these similarities, the Infection Control segment was combined with the Disposable Protective Apparel segment during the first 2019. The Company’s products are sold under the “Alpha Pro Tech” brand name, and under private label, and are predominantly sold in the United States of America (“U.S.”).

Based on these similarities, we determined that it would be best to consolidate the Infection Control segment into the Disposable Protective Apparel segment beginning with the first 2019. Segment data excludes charges allocated to the principal executive office and other unallocated corporate overhead expenses and income tax.
