易揭膜

今天逛超市的时候，看见类似这种的，或者养乐多瓶盖上的膜，我回去查了一下，看这种膜被称为易揭膜，也叫封口膜，是功能性专用膜，他和普通薄膜的区别：
1.原料配方易接膜
必须加 EVA、特殊共聚料、开口调节剂，专门控制热封强度，
2.封口性能
3.撕开方式
普通膜：破坏性撕开，把膜本身纤维扯断。
易接膜：界面剥离，从封口层之间轻轻分开，膜整体不烂。

I remember Charles also explained to me about easy-open film and sealing before. This makes the concept much clearer now. Appreciate the information.

Last year, we produced a sample lidding film for a retortable bowl, it's retortable and easy to peel.
But the customer disappeared after the sample test, I'm so upset.
