Description

一种全降解的保温环保速运包装袋
技术领域
本实用新型属于包装用品技术领域，具体涉及一种可全降解的速运包装袋。
背景技术
保温环保速运包装袋，以全生物基新型可塑性材料，通过多种成型技术制造，避开了传统的以木材基、石油基等非环保材料的使用，普及使用本发明有效减少木材和石油化工材料的消耗，防止自然生态系统失衡及化工材料对环境的污染和破坏。
聚乳酸(PLA)是一种新型的生物降解材料，使用可再生的植物资源(如玉米)所提出的淀粉原料制成。淀粉原料经由发酵过程制成乳酸，再通过化学合成转换成聚乳酸。其具有良好的生物可降解性，使用后能被自然界中微生物完全降解，最终生成二氧化碳和水，不污染环境，这对保护环境非常有利，是公认的环境友好材料。
包装袋根据包装物的不同，在结构设计上也有区别，食品的保存和运输一直是有着较高的标准，因此针对食品的包装一直是业内关注的课题。
实用新型内容
本实用新型的目的是提供一种全降解的保温环保速运包装袋，产品原料简单，结构上具有较好的缓冲和保温作用。
本实用新型解决上述问题所采用的技术方案为：一种全降解的保温环保速运包装袋，包括袋体，该袋体的一侧开口作为放料或取料口，所述袋体包括面层、里层，面层和里层之间形成夹层，所述面层的外表面设有淋膜层，夹层内填充保温纤维，袋体的开口边缘连接有封条，所述封条具有连接宽边，该连接宽边与袋体开口的边缘热压连接；所述面层和里层分别是一片式PLA无纺布，面层和里层叠合构成袋体，袋体的两侧边再对合热压连接形成袋体封闭的两侧边。
优选地，所述面层的外表面为20-60g/平方米淋膜层。
优选地，所述保温纤维为4D～10D的PLA短纤维。
上述热压连接具体为超声波热压缝合的连接。
本申请的封条采用PLA和PBAT的复合材料进行制作，强度上满足了使用要求，同时实现了随袋体一起降解
与现有技术相比，本实用新型的优点在于：提供了一种全降解的保温包装袋，该袋体采用可降解的PLA无纺布作为袋体，不仅更加环保而且更加安全，能够适用于食品的包装，且袋体具有夹层结构，并在夹层中填充PLA纤维作为保温纤维，隔尘、隔温有助于延长食品的保质期，且填充纤维对包装物有缓冲保护作用。
附图说明
图1为本实用新型实施例包装袋(表面无淋膜层)的示意图；
图2为本实用新型实施例包装袋的另一视图；
图3为本实用新型实施例包装袋开口部位的局部放大图(面层外面涂有淋膜层)。
具体实施方式
以下结合附图实施例对本实用新型作进一步详细描述。
如图1-3所示，本实施例中的全降解的保温环保速运包装袋，包括袋体，该袋体的一侧开口作为放料或取料口，袋体包括面层1、里层2，面层1和里层2之间形成夹层，夹层内填充保温纤维(图中未示出)，袋体的开口边缘连接有封条3，封条3具有连接宽边301，该连接宽边301与袋体开口的边缘热压连接。面层1和里层2分别是一片式PLA无纺布，面层1和里层2叠合构成袋体，袋体的两侧边再对合热压连接形成袋体封闭的两侧边。
面层的外表面为20-60g/平方米的淋膜层4，淋膜层便于印刷图案，也可起到防水的作用。
PLA无纺布的制作原料以及夹层内填充的保温纤维为4D的PLA短纤维，纤维长度30-120mm。
上述结构的速运包装袋，原料可降解，且具有保温防潮的特性，适用于食品运输包装领域。
除上述实施例外，本实用新型还包括有其他实施方式，凡采用等同变换或者等效替换方式形成的技术方案，均应落入本实用新型权利要求的保护范围之内。
