• ASTM D3981 – 09A(2016) Standard Specification for Polyethylene Films Made from Medium-Density Polyethylene for General Use and Packaging Applications
• ASTM D3892 – 15(2020) Standard Practice for Packaging/Packing of Plastics
• ASTM D7568 – 17 Standard Specification for Polyethylene-Based Structural-Grade Plastic Lumber for Outdoor Applications
• ASTM D4801 – 08(2016) Standard Specification for Polyethylene Sheeting in Thickness of 0.25 mm (0.010 in.) and Greater

• 1.1 This specification covers unpigmented, unsupported, low-density polyethylene and linear low-density polyethylene films (hereafter referred to as film or films) with densities ranging from 0.910-0.925 g/cm ³ per Specification D4976.

  NOTE 1:  The density of a film will not necessarily be equal to the density of a molded plaque from the same resin.

  NOTE 2:  Blends of ethylene/vinyl acetate (EVA) with low-density polyethylene may have densities up to 0.929 g/cm ³.

  1.2 This specification is applicable to homopolymer polyethylene, but is not restricted to it. It is applicable to films made from polyethylene copolymers, and also applicable to films made from blends of homopolymers and copolymers, including ethylene/vinyl acetate copolymers.

  1.3 The thickness of the films covered by this specification is 101.6 μm or less (0.004 in. or less), inclusive. The maximum width of the sheet or layflat is 3.30 m (130 in.).

  1.4 This specification does not cover oriented heat-shrinkable films.

  1.5 This specification allows for the use of recycled polyethylene film or resin as feedstock, in whole or in part, as long as all of the requirements of this specification are met and as long as any specific requirements as governed by the producer and end user are also met. (See Note 3.)

  NOTE 3:  Guide D7209 describes terminology and definitions related to recycled plastics.
