摘要
尼龙薄膜具有优异的力学性能、透明性好、气体阻隔性高等优点,被广泛应用于食品包装、日用品包装等领域。对比测试了直线易撕裂尼龙薄膜和普通尼龙薄膜的力学性能,并采用一种简便的方法对直线易撕裂尼龙薄膜及其复合膜的直线撕裂性能进行评估。结果表明,直线易撕裂尼龙薄膜具有优异的直线撕裂性能和力学性能。
Nylon film had been widely used in the field of food packing and commodity packaging,due to its excellent mechanical properties, good transparency and high gas barrier property. The mechanical properties of straight-line easy-tear nylon film and ordinary nylon film were compared. In addition,a simple and convenient method was used to investigate the linear tear properties of straight-line easy-tear nylon film and its laminated film. The results show that the straight-line easy-tear nylon film has excellent linear tear property and mechanical property.
