Description
技术领域
本发明属于物流包装材料技术领域，尤其涉及一种物流用高弹性紧固热粘膜。
背景技术
纸质材料与塑料薄膜构成的半透明物流用包装容器，既有助于消费者直观了解包装内容物的属性，具有良好的视觉展示效果，又有助于简化包装，减少包装废弃物的排放量。
然而，目前市面上这种包装结构，其塑料薄膜都是先通过涂胶（即涂或预涂）再与纸质材料进行边缘热压粘合，其弊端在于：1、生产过程存在溶剂挥发和残留隐患，既不利于环保，又对工人的身心健康产生威胁。2、因涂胶薄膜挺度大、韧性不足，导致包装容器无法根据包装内容物的体积进行折叠紧固，存在内容物在包装容器中晃动风险。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种物流用高弹性紧固热粘膜。
为了实现上述的目的，本发明提供以下技术方案：
一种物流用高弹性紧固热粘膜，包括外层、芯层和热粘层，
所述外层材料是由改性聚乙烯和爽滑剂组成；
所述芯层材料是由聚乙烯组成；
所述热粘层材料是由乙烯-醋酸乙烯共聚物、热塑性弹性体和氢化苯乙烯-丁二烯嵌段共聚物组成。
进一步的，所述外层材料中按质量百分比改性聚乙烯为95-97%，爽滑剂为3-5%。
更进一步的，所述改性聚乙烯由以下重量份的原料制成：低密度聚乙烯75-80份、麻纤维10-15份、青霉素菌渣8-12份、马来酸酐接枝聚乙烯4-5份、聚乙烯蜡2-3份、白油0.5-0.8份、三乙醇胺3-4份。
更进一步的，所述改性聚乙烯的制备方法为：将青霉素菌渣烘干后与三乙醇胺混合后密封熟化12-24小时，之后再与其他原料混合送入高混机中搅拌混匀，完成后再送入双螺杆挤出机中，控制挤出温度为140-170℃，主机转速25Hz，喂料速度15Hz，挤出造粒得到。进一步的，所述芯层材料的聚乙烯为低密度聚乙烯和/或茂金属聚乙烯。
优选的，所述低密度聚乙烯的密度为0.91-0.93g/cm3，熔融指数为1.85-2.0g/10min。
优选的，所述热粘层材料中乙烯-醋酸乙烯共聚物的密度为0.92-0.95g/cm3，熔融指数为1.9-2.2g/10min。
进一步的，所述热粘层材料中乙烯-醋酸乙烯共聚物的醋酸乙烯含量为15-25%。
优选的，所述热粘层材料中热塑性弹性体的密度为0.85-0.89g/cm3，熔融指数为2.0-3.0g/10min。
进一步的，所述热粘薄膜采用三层共挤流延法一次成型制造得到，具体步骤为：将外层、芯层和热粘层材料配方经计量后，分别混合均匀加入料斗，进入挤出机中，通过共挤复合模头形成三层薄膜挤出，经风刀和冷却辊作用是内部结晶均匀，在牵引过程中经电晕处理，达到标准后对薄膜边角进行切边修整，最后通过收卷机收卷即得。
本发明的优点是：
1、本发明采用三层共挤流延法制造，一次成型，成本低、能耗小。
2、能够与纸质材料直接热压粘合，无需涂胶，无环保及职业健康隐患。
3、薄膜具有高弹性、高韧性，能够通过折叠实现紧固包装内容物的目的。
4、本发明使用改性聚乙烯作为薄膜外层材料，向其中加入了麻纤维、青霉素等生物质材料，通过高混机令生物质材料均匀分散于低密度聚乙烯后，外层材料所受外界应力会通过聚乙烯基体传递给具有较高拉伸强度的生物质材料，使改性后的聚乙烯具有更优秀的力学性能，以满足通过折叠实现紧固包装内容物的性能需求，同时生物质材料还能够实现废弃物的资源化利用，并有助于提高热粘薄膜的降解能力，实现力学性能和环保的同步提升。
