近年来,随着高性能树脂生产技术的改善和提高,应用在可挠性包装薄膜中,使改善其机械加工性、密封性、阻隔性、透明性、光泽度、强韧性、印刷性及回收再利用性成为可能。尤其是下列三种特殊树脂在可挠性包装薄膜领域的应用十分引人注目。它们是:环状链烯烃共聚物(CyclicOlefinCopolymers,简称COCs)、液态结晶聚合物(LiquidCrystalPolymers,简称LCPs)和苯乙烯-丁二烯共聚物(Styrene-ButadieneCopolymers,简称SBCs)。现介绍如下:
In recent years, with the improvement and improvement of the high-performance resin production technology, it is applied in a flexible packaging film to improve its machinability, sealability, barrier property, transparency, glossiness, toughness, printability and recovery Reuse is possible. In particular, the following three kinds of special resins in the field of flexible packaging film is very attractive. They are: Cyclic Olefin Copolymers (COCs), Liquid Crystalline Polymers (LCPs) and Styrene-Butadiene Copolymers (SBCs). Now introduced as follows:
