Abstract

本实用新型提供了一种防水透气高强度复合包 装制品,以聚丙烯为表层,聚乙烯为次层,无防布为中 层,聚乙烯为内层。在制品上有防水透气微孔。具有 透气、防水、抗撕裂、无毒、易热封、成本低、用途广等 优点,可用于食品和多种物品的包装。

Description

本实用新型涉及的是一种防水透气高强度复合包装制品。
目前国内外使用的包装制品为纸/塑、塑/塑复合材料,防水不透气,透气不防水,或不抗撕裂,功能单一。
本实用新型提供了一种既防水又透气、高强度、易热合、无遗漏可用于食品和多种物品包装的制品。
本实用新型中有依次连接的聚丙烯(BOPP)表层,聚乙烯(PE)次层,无纺布中层,聚乙烯(PE)内层(参见图1)。表层具有抗撕裂和防水作用,次层具有粘合作用,中层具有防漏回弹作用,内层具有热封作用。
上述包装制品各层结构厚度为:
表 层 15μ-30μ
次 层 15μ-30μ
中 层 50μ-100μ
内 层 15μ-30μ
上述包装制品中有透气无遗漏的微孔(参见图1)。
上述包装制品中微孔孔径及孔距如下:
孔 径 0.001mm-0.1mm
孔 距 1mm-20mm
本实用新型防水透气包装制品具有如下效能:
1.透气量可任易调节
2.水滴不易进入,不易污染
3.抗撕裂强度高
4.无毒、无异味、卫生安全、可用于食品和多种物品包装,
5.热封牢固平整,
6.粉末不易遗漏,具有过滤功能,
7.能缓冲水滴进入和碰压冲击,
8.工艺简单,成本低、用途广。
下面结合附图介绍本实用新型实施例
图1为本实用新型结构示意图。
参见图1,本实用新型中有20μBOPP的表层1,20μPE的次层2,30g/m2无纺布中层3,20μPE内层4。根据透气量大小确定相应微孔5的数量,本实施例中的孔距为5×6mm,孔径为0.01mm。
本实施例中的包装制品可用于干燥剂,抗氧剂、保鲜剂、发热剂等多种物品的包装。
