Standard Specification for Plastic Films Made from Low-Density Polyethylene and Linear Low-Density Polyethylene for General Use and Packaging Applications
2016

ASTM Vol.08.02 (2022)
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/cm3 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/cm3. 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. 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.). This specification does not cover oriented heat-shrinkable films.
