A heat-sealable polymeric film includes a substrate layer of polymeric material having on a surface thereof a heat-sealable coating layer. The layer includes a copolyester having a degree of crystallinity of at least 5%, and is less than 8 μm in thickness. The copolyester consists essentially of repeat units of one or more aromatic dicarboxylic acids, one or more aliphatic dicarboxylic acids, and a stoichiometric amount of a glycol component consisting of one or more glycols selected from the group consisting of aliphatic glycols and cycloaliphatic glycols.
一种可热封的聚合薄膜包括一层聚合材料基材,在其表面有一层可热封的涂层。涂层包括结晶度至少为 5%、厚度小于 8 微米的共聚聚酯。该共聚聚酯主要由一种或多种芳香族二羧酸、一种或多种脂肪族二羧酸的重复单元和一定量的乙二醇组分组成,乙二醇组分包括从脂肪族乙二醇和环脂族乙二醇组成的组中选出的一种或多种乙二醇。
