Designation:D549108(Reapproved 2014)Standard Classification forRecycled Post-Consumer Polyethylene Film Sources forMolding and Extrusion Materials1This standard is issued under the fixed designation D5491;the number immediately following the designation indicates the year oforiginal adoption or,in the 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 derived 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.1.2 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,redemptionbags,bubblepackagingfilm,andcommercial/industrial liners/bags and overwrap.Other post-consumer PE films shall be added to this classification whensuch material streams are defined.1.3 It is not the function of this classification to provide datafor specific product design or process-performance purposes.1.4 The supplier shall provide a written certification witheach 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 thestandard.The values given in parentheses are for informationonly.NOTE1There is no known ISO equivalent to this standard.2.Referenced Documents2.1 ASTM Standards:2D883 Terminology Relating to PlasticsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD7209 Guide for Waste Reduction,Resource Recovery,andUse of Recycled Polymeric Materials and Products3.Terminology3.1 DefinitionsThe definitions used in this classificationare in accordance with Terminology D883 and Guide D7209.3.2 Definitions of Terms Specific to This Standard:3.2.1 bubble packaging film,nclear or tinted LDPE orLLDPE film with little or no print,used to cushion or to protectsurfaces,or both.3.2.2 commercial/industrial liners/bag,nclear LDPE,LLDPE,or MDPE film with light or no print,used for theshipment of industrial parts,mattresses or textile products,drynonputrescible foods,nonhazardous chemicals,etc.3.2.3 commercial overwrap,nclear LDPE,LLDPE,orMDPE film with light or no print,used to cover finishedproducts such as carpeting,furniture,yarn,and other interme-diate or retail items during shipment to the distribution outlet orfinal consumer.3.2.4 dry-cleaning film,nclear or pigmented film madefrom LDPE,LLDPE,or their blends,with light or no print,used as the outer protective wrap by dry-cleaning establish-ments.3.2.5 grocery sacks,npigmented or unpigmented blendsof polyethylene with or without print,used to carry groceriesfrom a food market.3.2.6 merchandise bags,npigmented LDPE,LLDPE,MDPE,HDPE,or a combination of these resin types,withprint,used to carry dry goods from a retailer.3.2.7 nominal density,nthe density of the unpigmentedpolyethylene resin.The nominal density differs from theapparent density of the material due to the addition of fillers orpigments to the resin.3.2.8 recycle bags,nblue tinted LLDPE or LDPE filmwith light or no print,used to transport items to a recyclingfacility.3.2.9 redemption bags,nclear or tinted LLDPE or LDPEfilm with little or no print,used to transport beverage bottles1This classification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.15 on ThermoplasticMaterials.Current edition approved Dec.1,2014.Published December 2014.Originallyapproved in 1993.Last previous edition approved in 2008 as D5491-08.DOI:10.1520/D5491-08R14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 and cans to a recycler in a“bottle bill”state where beveragecontainers require a refundable deposit upon purchase.3.2.10 shrink wrap,npigmented or unpigmented filmmade from LDPE,LLDPE,or their blends,clear or pigmented,with light or no print,that is typically used to unitize an itemor items for stability.3.2.11 source,nthe original end use of the PE materialsdescribed in this specification.3.2.12 stretch wrap,nclear or tinted LLDPE film,with noprint,used to unitize an item or items for stability.4.Si
