Lithium Battery PVC Heat Shrink Flat FilmPVC电池热缩平膜
PVC calendered heat shrink flat film is the basic substrate for the lithium battery PACK industry. It can be slitted, printed and rewound by factories. It is the upstream raw material for sleeve manufacturers, widely used for outer wrapping of battery packs and the insulation coating of power and energy-storage batteries.PVC 压延热缩平膜是锂电池 PACK 行业基础基材，工厂可分切、印刷、复卷，是套管厂上游原料；广泛用于电池组外包、动力电池与储能电池外层包覆。
Core selling points核心卖点
