Description

一种塑胶包装膜
技术领域
本发明属于塑胶领域，具体涉及一种塑胶包装膜。
背景技术
塑胶的定义(美国塑料工业协会)：主要由碳、氧、氢和氮及其他有机或无机元素所构成，成品为固体，在制造过程中是熔融状的液体，因此可以籍加热使其熔化、加压力使其流动、冷却使其固化，而形成各种形状，此庞大而变化多端的材料族群称为塑胶。
目前，部分物品在日光下曝晒的时间长，需要包装膜具有一定的耐用性，特别是防晒能力要好，而普通的塑胶包装膜透光性高，自身的防晒能力差，无法满足使用要求。
另外，现有的包装膜还存在一个问题，即其内外层容易脱开，导致包装膜出现损坏。
因此，提出一种塑胶包装膜是本发明所要研究的课题。
发明内容
本申请的主要目的在于提供一种塑胶包装膜，以解决现有包装膜防晒能力差、可靠性差等问题。
为实现前述申请目的，本申请采用的技术方案包括：一种塑胶包装膜，由外至内依次包括外防水层、粘结层以及内防水层，所述外防水层设于外侧，所述内防水层设于内侧，所述粘结层设置在外防水层和内防水层之间；所述外防水层为防水塑胶薄膜，且外防水层的外表面涂布有紫外线吸收层；所述粘结层由网纱和涂覆在网纱上的耐老化压敏粘结剂构成；所述内防水层为低密度聚乙烯薄膜，该低密度聚乙烯薄膜的内侧涂布有黑胶涂层。
进一步地，所述网纱为塑胶网纱。
进一步地，所述网纱为尼龙网纱。
进一步地，所述网纱为不锈钢网纱。
进一步地，所述外防水层。
进一步地，所述内防水层的内侧面还涂布有隔热层。
进一步地，所述黑胶涂层位于隔热层和低密度聚乙烯薄膜之间。
借由以上的技术方案，本申请的有益效果在于：本发明可靠性好、防晒能力佳、防水能力强，隔热效果明显，能够有效保护被包装的物品。
参照后文的说明和附图，详细公开了本申请的特定实施方式，指明了本申请的原理可以被采用的方式。应该理解，本申请的实施方式在范围上并不因而受到限制。在所附权利要求的精神和条款的范围内，本申请的实施方式包括许多改变、修改和等同。
针对一种实施方式描述和/或示出的特征可以以相同或类似的方式在一个或更多个其它实施方式中使用，与其它实施方式中的特征相组合，或替代其它实施方式中的特征。
应该强调，术语“包括/包含”在本文使用时指特征、整件、步骤或组件的存在，但并不排除一个或更多个其它特征、整件、步骤或组件的存在或附加。
附图说明
在此描述的附图仅用于解释目的，而不意图以任何方式来限制本申请公开的范围。另外，图中的各部件的形状和比例尺寸等仅为示意性的，用于帮助对本申请的理解，并不是具体限定本申请各部件的形状和比例尺寸。本领域的技术人员在本申请的教导下，可以根据具体情况选择各种可能的形状和比例尺寸来实施本申请。在附图中：

附图2为本实施例塑胶包装膜的爆炸示意图。
具体实施方式
实施例：一种塑胶包装膜
参见附图1-2，由外至内依次包括外防水层1、粘结层2以及内防水层3，所述外防水层1设于外侧，所述内防水层3设于内侧，所述粘结层2设置在外防水层1和内防水层3之间；所述外防水层1为防水塑胶薄膜，且外防水层1的外表面涂布有紫外线吸收层10；所述粘结层2由网纱20和涂覆在网纱20上的耐老化压敏粘结剂21构成；所述内防水层3为低密度聚乙烯薄膜，该低密度聚乙烯薄膜的内侧涂布有黑胶涂层30。
其中，所述网纱20可以为塑胶网纱、尼龙网纱或者不锈钢网纱。
另外，所述内防水层3的内侧面还涂布有隔热层31，所述黑胶涂层30位于隔热层31和低密度聚乙烯薄膜之间。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
