Description

一种高阻隔纸塑复合包装膜
技术领域
本发明属于纸塑复合包装膜技术领域，具体是涉及一种高阻隔纸塑复合包装膜。
背景技术
纸塑复合包装膜通常由塑胶与纸张复合而成，在软包装材质中应用较多，但由于纸张的特殊表面，在垂直包装设备上，特别是折叠衣领处有很高的摩擦系数，导致纸塑复合包装膜的阻隔性被降低较多，一般纸塑复合包装膜的透过性在包装前后会升高3-5倍。现有的纸塑复合包装膜主要是通过VMPET或铝箔作为纸塑复合包装膜的阻隔层，但在包装较大的摩擦力作用下，纸塑复合包装膜会出现微观的拉裂形变，而纸塑复合包装膜的阻隔性就可以因微观的形变而受到显著的影响，如VMPET、铝箔的微裂痕都会使纸塑复合包装膜的透湿、透氧参数升高。
发明内容
为了解决上述技术问题，本发明提供一种高阻隔纸塑复合包装膜。
为了实现本发明的目的，本发明采用了以下技术方案：
一种高阻隔纸塑复合包装膜，包括复合在纸层上的镀铝流延聚丙烯薄膜层，所述镀铝流延聚丙烯薄膜层分为复合在一起的电晕层、中间层、热封层，所述电晕层表面镀有铝层，所述电晕层、中间层、热封层的层厚比为(2.8～3.2):(20.5～21.5):(5.7～6.3)；所述电晕层包括环烯共聚物，所述中间层包括含有成核剂的均聚聚丙烯，所述热封层包括质量比为(0.9～1.1):(0.9～1.1)的三元共聚聚丙烯料一、三元共聚聚丙烯料二；所述三元共聚聚丙烯料一融指8g/10min，所述三元共聚聚丙烯料二融指7g/10min。
优选，所述三元共聚聚丙烯料一与三元共聚聚丙烯料二的质量比为1:1。
优选，所述环烯共聚物为日本宝理公司生产的牌号为8007F-500的产品；所述均聚聚丙烯为为博禄化工公司生产的牌号为HD915CF的产品；所述三元共聚聚丙烯料一为燕山石化公司生产的牌号为C5908的产品；所述三元共聚聚丙烯料二为湖石化学公司生产的牌号为SFC750M的产品或为新加坡聚烯烃公司生产的牌号为FL7641的产品。
本发明的有益效果在于：
(1)本发明纸塑复合包装膜具有高阻隔性能，成功解决了纸塑复合包装膜过包装设备后阻隔性下降的问题，本发明纸塑复合包装膜的阻隔性能稳定，适合各类填充包装形式。
本发明纸塑复合包装膜中电晕层、中间层、热封层中各原料类型的选择、原料配比以及各层之间的厚度差异，均是保证纸塑复合包装膜高阻隔性能的重要部分。
所述电晕层中环烯共聚物使得纸塑复合包装膜刚性、屈服强度、杨氏模量均得到提高；另外使得电晕层对铝具有很好的附着力，可以提高并保持电晕层的表面张力值，使得在镀铝工序中铝原子蒸汽在电晕层表面分布均匀致密，从而进一步提高纸塑复合包装膜的高阻隔性能。
所述中间层的均聚聚丙烯可以辅助提高纸塑复合包装膜的屈服强度，其中成核剂可以提高均聚聚丙烯的结晶度使得镀铝流延聚丙烯薄膜层的抗拉伸性能增强，有效避免了镀铝流延聚丙烯薄膜层因拉伸形变而造成的纸塑复合包装膜阻隔性能的降低。
本发明中镀铝流延聚丙烯薄膜层虽也有拉伸，但是相比于传统纸塑复合包装膜中VMPET阻隔层拉伸回复比例不同，本发明的镀铝流延聚丙烯薄膜层使整个纸塑复合包装膜不会形成氧气、水蒸气的直通缝隙，阻隔性能可以保持稳定。
(2)本发明提供的优选技术方案可以使得纸塑复合包装膜的阻隔性能达到最佳状态，且生产成本最低化。
