Abstract
本实用新型公开了一种耐热包装膜，其由外向内包括透明塑料层、印刷层和隔阻层，所述隔阻层包括环烯烃共聚物层和热封层，所述热封层为低密度聚乙烯层。与现有技术相比，本实用新型的隔阻层为环烯烃共聚物层和热封层复合，增强包装膜的耐热性和热稳定性，使包装膜的隔阻性能好；同时，由于隔阻层中与印刷层接触的为环烯烃共聚物层，不必再增加粘接层，减少生产成本。
Description
技术领域
本实用新型涉及复合膜技术领域，具体涉及一种可包装食品的耐热包装膜。
背景技术
目前，市场上大多数食品的包装膜结构为层状结构，由外至内依次为透明塑料层、印刷层、粘接层和隔阻层，隔阻层为聚乙烯和聚丙烯复合层。这种包装膜由于隔阻层为聚乙烯和聚丙烯材料，其耐热性及稳定性还存在一定的缺陷。另外，由于隔阻层为聚乙烯和聚丙烯复合层，因此，必须增加粘接层来增强包装膜的耐热性和稳定定，增加了包装膜的层状结构，增加了成本。
实用新型内容
本实用新型的目的在于克服上述现有技术的缺陷，提供一种耐热包装膜，该耐热包装膜具有较高的耐热性及热稳定性，阻隔性能好，可用于食品包装。
为实现上述目的，本实用新型采用如下技术方案：
耐热包装膜，由外向内包括透明塑料层、印刷层和隔阻层，所述隔阻层包括环烯烃共聚物层和热封层。
优选地，所述热封层为低密度聚乙烯层。
与现有技术相比，本实用新型的有益效果是：
隔阻层为环烯烃共聚物层和热封层复合，增强包装膜的耐热性和热稳定性，使包装膜的隔阻性能好；同时，由于隔阻层中与印刷层接触的为环烯烃共聚物层，不必再增加粘接层，减少生产成本。
附图说明
图1为本实用新型较佳实施例的结构示意图。
具体实施方式
下面结合附图和具体实施例子对本实用新型的耐热包装膜作进一步详细说明。
如图1所示，本实用新型的耐热包装膜为层状结构，可以采用现有普通的流延膜生产工艺制成，由外至内依次包括透明塑料层1、印刷层2和隔阻层，所述隔阻层包括环烯烃共聚物层31和热封层32。所述热封层32优选为低密度聚乙烯层。透明塑料层1的厚度为18～28um，印刷层2的厚度为15～20um，环烯烃共聚物层31的厚度为25～35um，热封层32的厚度为30～40um。
上述实施例仅为本实用新型的优选实施方式，不能以此来限定本实用新型的保护范围，本领域的技术人员在本实用新型的基础上所做的任何非实质性的变化及替换均属于本实用新型的保护范围。
Claims (2)
1.耐热包装膜，由外向内包括透明塑料层、印刷层和隔阻层，其特征在于：所述隔阻层包括环烯烃共聚物层和热封层。
2.如权利要求1所述的耐热包装膜，其特征在于：所述热封层为低密度聚乙烯层。
