Description

一种高强度聚乙烯薄膜
技术领域
本发明涉及印刷包装技术领域，具体为一种高强度聚乙烯薄膜。
背景技术
PE薄膜，即聚乙烯薄膜，是指用聚乙烯生产的薄膜。聚乙烯为典型的热塑性塑料，是无臭、无味、无毒的可燃性白色粉末。成型加工的PE树脂均是经挤出造粒的蜡状颗粒料，外观呈乳白色。其分子量在1万-l00万范围内。分子量越高，其物理力学性能越好，越接近工程材料的要求水平。但分子量越高，其加工的难度也随之增大。聚乙烯熔点为100-130℃，其耐低温性能优良。在-60℃下仍可保持良好的力学性能，但使用温度在80-110℃。
聚乙烯化学稳定性较好，但是在大气、阳光和氧的作用下，会发生老化，变色、龟裂、变脆或粉化，丧失其力学性能。聚乙烯无臭，无毒，手感似蜡，具有优良的耐低温性能，化学稳定性好，能耐大多数酸碱的侵蚀，而且质轻，无毒，具有优越的介电性能。但是市场上的聚乙烯薄膜，因为工艺及组分的因素，在使用时存在很多的不足，普遍存在机械强度不够、易腐蚀、易损坏、抗压强度不高的的缺点，使用效果欠佳。
