ASTM D5491-08(2022)

SIGNIFICANCE AND USE 4.1 This classification identifies sources of PE film. The separation by sources 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, commercial/industrial liners/bags, and commercial overwrap. 4.2 This classification is useful in characterizing post-consumer film to be used as a feedstock for recycling. 4.3 It is neither the intent nor the purpose of this classification to specify the suitability of the recycled material for specific applications. SCOPE 1.1 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. 1.2 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. 1.3 It is not the function of this classification to provide data for specific product design or process-performance purposes. 1.4 The supplier shall provide a written certification with each shipment stating that the material is derived from post-consumer PE film sources described within this classification. 1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. Note 1: There is no known ISO equivalent to this standard. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
