技术领域
本发明涉及一种高柔性的环保型收缩膜。
背景技术
在PE膜的使用过程中,由于收缩膜广泛地与空气、阳光等接触,其不可避免地会出现老化等问题,老化问题将直接影响着收缩膜的使用寿命。而为了避免饮料包装后,在运输使用过程中收缩膜的破裂,还需要提高PE热收缩膜的高韧性、柔软性。此外,由于PE收缩膜的大量使用,造成了对环境的污染,因此,在提高PE收缩膜使用性能的同时,还需要提高其环保性能。
发明内容
本发明的目的是为了克服以上的不足,提供一种柔软性高、韧性好、环保的一种高柔性的环保型收缩膜。
本发明的目的通过以下技术方案来实现一种高柔性的环保型收缩膜,一种高柔性的环保型收缩膜由以下重量份原料组份:
聚丙烯5-15份、聚乙烯15-20份、线性低密度聚乙烯30-40份、高密度聚乙烯1-5份、热塑淀粉60-80份、邻苯二甲酸二丁酯5-10份、聚乙烯蜡1-5份、抗氧剂 168 0.5-1份、氢化蓖麻油1-2份。
本发明的进一步改进在于:该膜可为单层或通过挤压机进行多层挤压而成。
本发明与现有技术相比具有以下优点:成分中的聚丙烯,提高了整体的柔软性;聚乙烯与线性低密度聚乙烯相比,材质软,柔软性好,具有高绝缘性;而线性低密度聚乙烯提高了表面光泽好,具有低温韧性、高模量、抗弯曲和耐应力开裂性,低温下抗冲击强度高;高密度聚乙烯提高了整体的耐高温、耐低温、耐蒸汽渗透性及抗环境应力开裂性;热塑淀粉作为主要成分,既可以进行热塑加工,又能快速、完全地在自然环境中降解,作为一种新型的全生物降解材料,能进行堆肥和重复利用,良好的热收缩性能,可以轻松地进行收缩套标的制作,符合环保理念,大大降低了收缩膜对环境造成的污染;邻苯二甲酸二丁酯是增塑剂,与热塑淀粉同时使用,提高了稳定性;聚乙烯蜡作为润滑剂醇提高了抗静电性和膜的柔软性;抗氧剂 168的添加,起到了提高稳定性、耐久性的作用;氢化蓖麻油提高了固化速率;综上,本发明具有透明度高、拉伸强度高,耐候性好,抗撕裂强度高、柔软性好、环保的优点。
