This specification covers unpigmented, unsupported, sheet or tubular, medium-density polyethylene films intended for general uses and packaging applications. The film shall be made from homopolymer polyethylene, copolymer polyethylene commonly referred to as low-pressure polyethylene, or blends of homopolymers and copolymers that include ethylene/vinyl-acetate copolymers. The specimens shall be conditioned before testing in the standard laboratory temperature. Tests shall be conducted to determine the physical properties of the specimens which shall conform to the following physical requirements: secant modulus or stiffness; kinetic coefficient of friction; optical properties such as clarity, gloss, and haze; surface treatment level or wetting tension; impact resistance; tensile strength and elongation at break; heat sealability; and odor level.
