This specification covers unpigmented, unsupported, low-density polyethylene films (hereafter referred to as film or films) for general use and packaging applications. It is applicable to films made from polyethylene copolymers, and also applicable to films made from blends of homopolymers and copolymers, including ethylene/vinylacetate copolymers. The low-density polyethylene film shall be classified by Types 1, 2, and 3; Surfaces 1, 2, and 3; Classes 1, 2, 3, and 4; and Finishes 1, 2, 3, and 4. The film shall be made from an ethylene homopolymer, ethylene copolymers, or blends of homopolymers or copolymers, or homopolymer and copolymer, so that it meets the density and other film requirements specified. Tests shall be performed to conform to the specified properties of the material in accordance with the following test methods: conditioning; test conditions; thickness; yield; flatness; density; coefficient of friction; clarity; haze; wetting tension; impact resistance; tensile properties; heat sealability; and odor.
