本标准规定了聚偏二氯乙烯(PVDC)、丙烯酸(AC)、改性聚乙烯醇(PVOH)互相搭配涂布在双向拉伸聚丙烯(BOPP)基膜上制得的涂布薄膜(简称 BOPP双面涂布膜)的分类、要求、试验方法、检验规则、标志、包装、运输和贮存。
本标准适用于以透明双向拉伸聚丙烯薄膜或白色发泡双向拉伸聚丙烯薄膜为基材膜,一面涂布丙烯酸(AC)、另一面涂布聚偏二氯乙烯(PVDC)或改性聚乙烯醇(PVOH)中的一种而制得的 BOPP双面涂布薄膜。
本标准不适用于与食品直接接触的涂布不同涂料的双向拉伸聚丙烯双面涂布膜。

Scope

This standard specifies the coating film (abbreviated as abbreviation) that polyvinylidene chloride (PVDC), acrylic acid (AC), and modified polyvinyl alcohol (PVOH) are coated on a biaxially oriented polypropylene (BOPP) base film. BOPP double-sided coated film) classification, requirements, test methods, inspection rules, signs, packaging, transportation and storage. This standard applies to transparent biaxially oriented polypropylene film or white foamed biaxially oriented polypropylene film as the base film, one side is coated with acrylic (AC), the other side is coated with polyvinylidene chloride (PVDC) or modified BOPP double-sided coated film made of one of polyvinyl alcohol (PVOH). This standard does not apply to biaxially oriented polypropylene double-sided coated films that are in direct contact with food and coated with different coatings.
