ASTM International Committee D20 on Plastics has revised standard D2103, “Standard Specification for Polyethylene Film and Sheeting,” to D2103-10. This specification covers the classification of polyethylene film and sheeting. Recycled polyethylene film or resin may be used as feedstock, and the film or sheeting may contain additives for surface property improvement, pigments, or stabilizers, or a combination of these, but they must conform to the requirements specified.
