Description

一种多层共挤聚烯烃热收缩膜材料
技术领域
本发明涉及塑料薄膜材料技术领域，具体涉及一种多层共挤聚烯烃热收缩膜材料。
背景技术
众所周知，矿物染料生产的某些合成材料不断污染着我们的环境，如由废弃塑料所引起的白色污染。大部分合成塑料在自然环境中很难降解，长期堆积会破坏土壤结构，污染地下水，危害海洋生物的生存。而天然有机高分子是生物可降解的可再生资源，可用来取代合成材料。天然生物材料废弃后被填入地下，这些材料在微生物的作用下会降解成水、二氧化碳和其他小分子，不会对环境造成任何污染。整个降解过程通常需要几个月或者几年，但是不会花费额外的成本。因此，天然生物降解材料被广泛用于食品、医药、纺织、造纸和汽车等行业中。生物降解材料在食品包装行业的应用有着广泛的前景。当前，许多生物降解材料已经被做成薄膜、纤维应用于食品包装行业。
传统食品包装一般使用塑料薄膜，但是塑料薄膜存在一些缺点，如在包装食品后，容易产生有害气体和异味，有的塑料薄膜对人体还有一定的毒性，并且，塑料膜性质稳定，使用后遗弃在环境中不易分解腐烂，长期存留，易引起环境污染等，而现在市场上开始盛行淀粉基或纤维素基的食品包装薄膜，但是其延展性较差，机械性能较差，容易发生断裂，造成其使用范围有限。
发明内容
本发明的目的是：提供一种多层共挤聚烯烃热收缩膜材料，以克服目前现有技术存在的上述不足。
为了实现上述目的，本发明提供如下的技术方案：
一种多层共挤聚烯烃热收缩膜材料，其特征在于：包括聚丙烯和聚乙烯两种主要塑料以及其它材料，所述聚丙烯的具体材料为聚丙烯6612、聚丙烯5606和聚丙烯ABPOF-7，所述聚乙烯的具体材料为聚乙烯2045、聚乙烯2645、聚乙烯 3BPO-7，个原料组分按质量份数比例如下：
聚丙烯6612 20-40份
聚丙烯5606 10-20份
聚丙烯ABPOF-7 10-5份
聚乙烯2045 40-60份
聚乙烯2645 10-15份
聚乙烯3BPO-7 5-10份。
进一步的，原料组分按质量份数比例如下：
聚丙烯6612 40份
聚丙烯5606 20份
聚丙烯ABPOF-7 8份
聚乙烯2045 35份
聚乙烯2645 10份
聚乙烯3BPO-7 6份。
进一步的，所述其他材料为抗氧化剂，所述抗氧化剂为抗氧化剂1010、抗氧化剂1076、抗氧剂1098中的一种。
进一步的，所述聚丙烯占总比为百分之三十四，所述聚乙烯占总比为百分之六十四。
本发明的有益效果为：发明所得包装薄膜材料遗弃后可自然降解，使天然资源得到科学利用的同时，减少了包装行业对于环境的污染，实现了可持续发展；所制备抗菌薄膜的机械强度高，且能够有效抑制细菌滋生进而提高对食品等的保鲜效果。
