2、he case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This document provides for the classification of post-consumer polyethylene(PE)film derive
3、d from specificsources.It also identifies characteristics useful in determiningthe acceptability of the film for recycling into molding andextrusion materials.It is neither the intent nor the purpose ofthis classification to specify the suitability of the recycledmaterial for specific applications.1
4、.2 This classification provides that the source of the mate-rial be listed as an aid in identification.The separation bysource also improves the usefulness of the material.Sourcesare post-consumer PE films from shrink wrap,dry cleaningfilm,merchandise bags,grocery sacks,stretch wrap,recyclebags,rede
