摘　　要：介绍了废聚乙烯塑料膜及制品的循环再生利用技术。原料采用100%废聚乙烯塑料膜,不需二次造粒、熔粒,直接一次熔融制成新塑料膜;突破了传统工艺在废聚乙烯塑料再生利用过程中只能添加10%废料,而且必须经过造粒、熔粒二次熔融才能成膜的技术难题。The recycling utilization technology of waste polyethylene plastic and products is introduced. Waste polyethylene plastic is adopted as 100% ,without secondary granulation and melt tablets, the new plastic film is directly prepared. The technical problem which exists in the traditional recycling process of waste polyethylene plastic is resolved, in which it needs 10% of waste plastic added only,and the new plastic film is so prepared after such technical difficulties are to be overcome as granulation, melt tablets of the second melting.

关 键 词：废聚乙烯塑料膜 一次熔融 再生利用 新工艺
