目的 通过对标，帮助企业找出执行标准与国际先进标准之间的差距，参与制定国际标准，填补国内包装薄膜材料及袋标准的空白，提升企业标准化工作能力和水平。方法 以包装薄膜材料和袋产品为例，查阅产品质量性能指标的国际先进标准，研制ISO 15988:2003，ISO 17555:2003，ISO 8367-1—1993，ISO 8367-2—1993对标技术方案。结果 双向拉伸PET聚酯薄膜有2家企业的2个产品对标;BOPP薄膜有2家企业的5个产品对标;纸袋有3家企业的3个产品对标。7家企业10个产品相应的全部或部分性能指标达到或优于对标技术方案中的指标。结论 通过比对发现，目前包装薄膜材料和袋产品标准内容相对完善，性能测试基本采用国际标准和国家标准的测试方法。企业对标结果显示，大部分产品均达到或优于对标方案要求，但因为包装薄膜材料和袋产品的应用范围广泛，针对产品包装要求的不同，技术指标要求会略有不同。

The work aims to help enterprises find out the gap between implementation standards and international advanced standards through benchmarking, participate in the formulation of international standards, fill the gaps in domestic packaging film materials and bag standards, and improve the standard working ability and level of enterprises. With packaging film materials and bag products as examples, international advanced standards on quality and performance indexes of products were reviewed to develop ISO 15988:2003, ISO 17555:2003, ISO 8367-1—1993, ISO 8367-2—1993 benchmarking technical schemes. Two-way stretch PET polyester film had 2 products from 2 enterprises for benchmarking; BOPP film had 5 products from 2 enterprises for benchmarking; and paper bag had 3 products from 3 enterprises for benchmarking. All or part of the corresponding performance indexes of 10 products from 7 enterprises reached or were superior to those in the standard technical scheme. Through comparison, it is found that standards relevant on packaging film materials and bag products are relatively complete, and the test methods adopted are basically from international and national standards. The results of benchmarking show that most of the products meet or exceed the requirements of benchmarking scheme. However, due to the wide application of packaging film materials and bag products, the requirements of technical indicators will be slightly different according to the different packaging requirements of products.
