Abstract: 本发明提供了一种封装组合物、组合物、封装胶膜、电子元器件及太阳能电池组件。该封装组合物包括聚烯烃树脂、聚乙二醇二甲基丙烯酸酯以及有机过氧化物，聚乙二醇二甲基丙烯酸酯的结构式为式(I)：其中，n为2～5的整数。极性的乙二醇二甲基丙烯酸酯和非极性的聚烯烃树脂热力学不相容，当聚烯烃树脂受热熔融后，乙二醇二甲基丙烯酸酯在聚烯烃树脂中分层并聚集。同时，通过固化在聚烯烃树脂基体中的原位形成一种三维网状结构的带有若干酯基和醚键的聚合物网络结构，该聚合物网络结构能够吸附聚烯烃树脂中残存的金属离子，从而降低金属离子的移动能力，进而提高聚烯烃树脂的干绝缘电阻，且上述组合物的组分简单、原料易得、成本较低。

Abstract: Disclosed herein is an intrusion resistant thermal laminating film having a first multilayer structure of a polyester polymer layer and an ethylene methyl acrylate copolymer layer adhered thereto. The first multilayer structure is exposed to UV radiation for an effective period. A first adhesive layer is on the first multilayer structure and is an ethylene vinyl acetate copolymer or an ethylene ethyl acrylate copolymer. The film also has a printed layer of a polyolefin or a polyvinyl chloride attached to the adhesive layer. The film has high clarity and is free of a primer. The printed layer cannot be separated from the first multilayer structure without destroying the film. The film exhibits no signs of orange peel.
