Description

一种高阻隔抗菌聚丙烯薄膜
技术领域
本发明涉及包装材料领域，具体是一种高阻隔抗菌聚丙烯薄膜。
背景技术
聚丙烯薄膜是以代替玻璃纸为目的而发展起来的一种新型包装薄膜，它具有机械强度高、韧性好，透明度和光泽度较好等特点。其价格比玻璃纸低20％左右。所以在食品、药品、香烟、纺织品等包装中已取代或部分取代了玻璃纸。但不具备抗菌性和抗静电性，随着包装材料的应用，废弃塑料带来的“白色污染”也越来越严重，随着人们环保意识的增强，如何缓解白色污染已是人们日益关注的话题。。随着人们对产品外包装的美观效果和质量的要求越来越高，对CPP薄膜的高阻隔性也提出了进一步要求，而现有的CPP薄膜难以达到要求
