1.1 本文件规定了特定来源的消费后聚乙烯（PE）薄膜的分类。它还确定了有助于确定膜回收到成型和挤压材料中的可接受性的特征。本分类的目的和目的都不是指定回收材料在特定应用中的适用性。 1.2 该分类规定将材料来源列为识别的辅助工具。源分离也提高了材料的有用性。来源是消费后PE膜，来自收缩包装、干洗膜、商品袋、杂货袋、拉伸包装、回收袋、赎回袋、气泡包装膜、商业/工业衬垫/袋和外包装。 定义此类材料流时，应将其他消费后PE膜添加到此分类中。 1.3 该分类的功能不是为特定产品设计或过程性能目的提供数据。 1.4 供应商应在每次装运时提供书面证明，说明材料来源于本分类中所述的消费后PE膜来源。 1.5 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 注1: 没有已知的ISO等效于本标准。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 该分类确定了PE膜的来源。源分离也提高了材料的有用性。来源是消费后PE膜，来自收缩包装、干洗膜、商品袋、杂货袋、拉伸包装、回收袋、赎回袋、气泡包装膜、商业/工业衬垫/袋和商业外包装。 4.2 这种分类有助于描述用作回收原料的消费后薄膜。 4.3 本分类的目的和目的都不是指定回收材料在特定应用中的适用性。

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. ====== 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.
