This standard replaces GB 10457-1989 “Cling wrap polyethylene film for keeping fresh of food”. Compared with GB 10457-1989, the main changes of this standard are as follows. - CHANGE the standard name from the “Cling wrap polyethylene film for keeping fresh of food” to the “Plastic cling wrap film for keeping fresh of food”; - EXTEND the scope of standard from the cling wrap polyethylene film for keeping fresh of food to the other plastic cling wrap film for keeping fresh of food; - ADD the technical requirements for raw materials; - CHANGE the length deviation to the roll weight deviation; - CHANGE the gas transmission to gas transmission deviation; - CHANGE the moisture transmission to moisture transmission deviation; - ADD the nominal value of the marking volume, gas transmission, and moisture transmission; - ADD the requirements for the marking material. This standard was proposed by the China Light Industry Federation. This standard shall be under the jurisdiction of the National Plastic Product Standardization Technical Committee. The drafting organizations of this standard. Institute of Light Industry Plastics Processing and Application, Shenzhen Wandajie Plastic Products Co., Ltd., Shenzhen Junhao Plastic Products Co., Ltd., National Quality Supervision and Inspection Center for Plastics (Beijing). The main drafters of this standard. Chen Jiaqi, Weng Yunxuan, Chen Qian, Xu Lidan, Wei Wenchang, Su Junming. This Standard replaces the standard previously issued as follows. - GB 10457-1989. Plastic cling wrap film for keeping fresh of food 1 Scope This standard specifies the terms and definitions, product classification, identification, requirements, test methods, inspection rules and marking, packaging, transportation and storage of plastic cling wrap film for keeping fresh of food. This standard applies to the plastic cling wrap film for keeping fresh of food which is produced using the polyethylene, polyvinyl chloride, polyvinylidene chloride and other resins as the main raw material through a single layer extrusion or multi-layer co-extrusion process (hereinafter referred to as wrap film). 2 Normative references The provisions in following documents become the provisions of this Standard through reference in this Standard. For the dated references, the subsequent amendments (excluding corrections) or revisions do not apply to this Standard; however, parties who reach an agreement based on this Standard are encouraged to study if the latest versions of these documents are applicable.
