摘要
以LDPE/LLDPE为基体材料,添加A型纳米活性分子筛,考察其对包装膜物理性能、力学性能和透气、透湿性能的影响。结果表明:保鲜包装膜的拉伸和热封性能下降,撕裂性能上升;保鲜膜的透明性有所下降。保鲜膜的透气和透湿性能大幅提高,非常利于果蔬的保鲜。
A type-A nano-active molecular sieve was added into LDPE/LLDPE to prepare fresh-keeping films. The physical properties , mechanical properties , and permeating properties were examined. It was showed that the tensile strength and heat seal properties of the films were decreased , yet the tear strength increased. The transparence of the films dropped a little. The air-permeating and water-permeating properties distinctly increased, which was good to fresh-keeping.
