| 中文摘要: |
| 以低密度聚乙烯（LDPE）和线性低密度聚乙烯（LLDPE）（质量比为80∶20）作为基础物质，添加不同比例的分子筛，吹制保鲜膜，研究了保鲜膜的力学性能和摩擦性能。研究表明：随着分子筛含量的增加，薄膜的拉伸强度、伸长率、耐戳穿强度和撕裂强度均出现一定程度的下降；加入分子筛之后，保鲜膜的摩擦系数上升。 |
| 英文摘要: |
| Low density polyethylene (LDPE) and linear low density polyethylene were used as basic materials, and different weight molecular sieve was added into them to make fresh-keeping films. The mechanical and friction performance of the films was studied. The results showed that with the increase of molecular sieve content, the tensile strength, elongation, puncture resistance strength, and tear strength decrease, but the coefficient of friction increase. |
