Description

一种抗压抑菌的药品包装用复合膜
技术领域
本发明涉及药用包装技术领域，尤其涉及一种抗压抑菌的药品包装用复合膜。
背景技术
药品作为一种特殊的商品与人们的身体健康和生命息息相关，如何完好地保持药品的性能，其包装起着决定性的作用。随着经济和技术的发展，医药工业迅猛发展，越来越多的药品生产企业通过了GMP认证，企业实力不断加强，药品包装业近年来也显示出勃勃生机。药品其主要作用是保护和改善人类健康，从而决定了药品包装的主要作用是在各种条件下长时间地保证药品的安全性、有效性和稳定性。近年来，因技术进步，人类对健康的关注和环保意识的增强，药品包装向着更安全、更全面和无污染的方向发展。世界药品包装正向多元化、包装材料多样化、着重安全、顺应环保的趋势发展。在材料的使用上，医药用包装趋于采用多层复合薄膜以增强强度。
国家知识产权局于2015年15月26日公布的一篇专利申请号为201310453567.X，名称：具有高阻隔性能的复合膜的专利，此专利提出如下技术方案：包括外表层、中间层、内层以及粘胶层。用该复合膜包装药品，在搬运药品的过程中，很可能因为挤压会对使复合膜内的药品损坏，同时一旦外表层破损，细菌很有可能进入复合膜内，从而会使复合膜内的药品受到污染。
目前市场上大多数药用复合膜的外层受到磨损或刮擦时，很容易破损，这样外界的污染物质很容易通过缝隙进入药品中，从而对药品造成污染；同时药品在搬运的过程中，很容易会对膜内的药品造成一定的挤压，从而使得药品受损。
发明内容
本发明要解决的技术问题是提供一种抗压性能好、抗菌效果良好且结构简单的药品包装用复合膜，本发明通过在第一聚乙烯层和第二聚乙烯层中填充有抗菌剂来实现抗菌效果；同时在玻璃纸层和铝箔层之间设置气泡层,并且在气泡中填充泡沫颗粒来实现减震抗压的效果。
为了解决上述技术问题,本发明提供了一种抗压抑菌的药品包装用复合膜，所述复合膜从外到内依次为第一聚乙烯层、玻璃纸层、气泡层、铝箔层、镀铝聚乙烯薄膜层及第二聚乙烯层，所述第一聚乙烯层与玻璃纸层之间、玻璃纸层与气泡层之间、气泡层与铝箔层之间、铝箔层与镀铝聚乙烯薄膜层之间、镀铝聚乙烯薄膜层与第二聚乙烯层之间均通过粘结剂粘合连接，所述气泡层中的气泡内均填充有纳米级泡沫颗粒，所述第一聚乙烯层及第二聚乙烯层中均添加有抗菌剂，且抗菌剂分别占第一聚乙烯层及第二聚乙烯层总含量的1％～3％。
进一步地，所述粘结剂为聚氨酯胶黏剂。
进一步地，所述抗菌剂为香草醛。
进一步地，所述泡沫颗粒为聚乙烯颗粒或橡胶颗粒。
进一步地，所述第一聚乙烯层和第二聚乙烯层的厚度范围为0.1～0.3mm；所述玻璃纸层的厚度范围为0.02～0.04mm；所述气泡层的厚度范围为0.03～0.06mm；所述铝箔层的厚度范围为0.02～0.06mm；所述镀铝聚乙烯薄膜层的厚度范围为0.02～0.03mm。
进一步地，所述粘结剂的厚度范围为0.004～0.01mm。
与现有技术相比，本发明所达到的有益效果：
(1)本发明中在玻璃纸层和铝箔层之间设置气泡层，且气泡内填充有纳米级泡沫颗粒，由于气泡层具有良好的减震抗压性能，在搬运过程中，可有效防止复合膜内药品受挤压而损坏的现象；当药品受到撞击时，气泡层中的气泡会压缩，当气泡碰到气泡内的纳米级泡沫颗粒时，气泡会反弹，起到缓冲作用，不至于气泡爆裂；本发明在第一聚乙烯层和第二聚乙烯层中填充有抗菌剂，一旦第一聚乙烯层发生破损，有害物质还是无法进入复合膜中去污染药品，从而延长了药品的保质期。
(2)本发明中的聚乙烯层具有耐磨性高、无毒、无臭且能耐大多数酸碱的侵蚀，因此，在运输的过程中可以有效保护复合膜内的药品；本发明中的玻璃纸层透明度很高，玻璃纸层表面不会产生静电，因此不会在其表面粘上灰尘，可保持复合膜表面的清洁。
(3)本发明中粘结剂为聚氨酯胶黏剂，该聚氨酯胶黏剂受热后排放的气体进入大气中，不会影响药品本身的药效，另一方面也不会对大气造成污染，聚氨酯胶黏剂属于绿色粘结剂。
(4)本发明中在气泡层和第二聚乙烯层之间设置铝箔层，一方面铝箔层可以隔绝外界的光、空气以及水蒸气，从而延长药品的保质期，另一方面还具有成本低、生产速度快和方便运输等优点。
综上所述，本发明中的复合膜具有良好的抗压性能，同时还能阻碍有害物质进入第二聚乙烯层中污染药品，具有极大的应用前景。
附图说明
以下结合附图及具体实施方式对本发明作进一步详细说明。
图1是本发明的剖视图；
附图标记说明：1、第一聚乙烯层，2、玻璃纸层，3、气泡层，4、铝箔层，5、镀铝聚乙烯薄膜层，6、第二聚乙烯层。
具体实施方式
以下实施例仅用于说明本发明，但不用来限制本发明的范围。
