一种CPP薄膜及其生产工艺
摘要：
本发明涉及薄膜生产技术领域，尤其是一种CPP薄膜，包括电晕处理层、中间层和热封层，电晕处理层和热封层均由聚丙烯材料制作而成；中间层为均聚物制成，且中间层上设有多个透气孔；透气孔的直径为0.002～0.012mm。本方案的CPP薄膜的透气性好。
摘要（英）：

The invention relates to the technical field of thin film production, especially relates to a CPP thin film which comprises a electric corona treatment layer, a middle layer and a heat sealing layer.The electric corona treatment layer and the heat sealing layer are prepared by polypropylene materials; the middle layer is prepared by homopolymer and a plurality of air holes are formed on the middle layer; diameter of the air hole is 0.002 to 0.012mm. The CPP thin film provided by the invention has good air permeability.
