Standard Classification for Recycled Post-Consumer Polyethylene Film Sources for Molding and Extrusion Materials
2014
3
ASTM Vol.08.03 (2022)
This document provides for the classification of post-consumer polyethylene (PE) film derived from specific sources. It also identifies characteristics useful in determining the acceptability of the film for recycling into molding and extrusion materials. It is neither the intent nor the purpose of this classification to specify the suitability of the recycled material for specific applications. This classification provides that the source of the material be listed as an aid in identification. The separation by source also improves the usefulness of the material. Sources are post-consumer PE films from shrink wrap, dry cleaning film, merchandise bags, grocery sacks, stretch wrap, recycle bags, redemption bags, bubble packaging film, and commercial/industrial liners/bags and overwrap. Other post-consumer PE films shall be added to this classification when such material streams are defined. It is not the function of this classification to provide data for specific product design or process-performance purposes.
