Description

一种复合型纸袋
技术领域
本发明涉及纸制品加工技术领域，具体涉及一种复合型纸袋。
背景技术
现在，人们在超市、菜市场等场所购物时，已经习惯于使用一次性塑料薄膜袋，但随着世界环境越来越差，人们环保意识的增强，已经充分认识到一次性塑料薄膜袋对环境的污染，各国都在纷纷禁止使用一次性塑料薄膜袋购物，采用能多次使用的布袋或用环保材料制成的购物袋。纸制袋就是其中的一种，但纸制袋有一个最大的不足就是强度差，使用时经常出现破裂，人们为了加强纸制袋的强度，一般都采用复合纸为原料，即在纸张的单面或双面涂塑料膜或镀铝箔。
而随着纸袋的市场的发展，对纸袋的要求也越来越高，纸袋的结构也各式各样，但对纸袋的抗拉强度、防潮性能、耐磨性能等综合性能仍是纸袋的测试标准。另一方面，这种产品也只能一次性使用，当使用后废弃时，因其上涂有塑料膜或铝箔，在自然界很难降解，回收再利用也有难度，对环境同时造成一定的污染。
因此，针对上述问题，本发明提出了一种新的技术方案。
发明内容
本发明的目的是提供一种能重复使用、具有防潮、耐磨性能，同时抗拉强度高的复合型纸袋。
本发明是通过以下技术方案来实现的：
一种复合型纸袋，包括纸袋本体、外膜、内膜和纸袋底部，所述纸袋本体与纸袋底部相连，所述纸袋本体内侧设有内膜，所这纸袋本体外侧设有外膜，所述纸袋本体上设有折叠线，所述折叠线下方设有提手孔，所述提手孔外围设有加强层。
进一步地，所述纸袋本体和纸袋底部为一体结构。
进一步地，所述内膜为聚乙烯材料。
进一步地，所述外膜为有机硅树脂材料制成。
进一步地，所述纸袋底部设有硬质木架。
本发明的有益效果是：本发明所提出的纸袋，设计合理，结构新颖，具有良好的防潮、耐磨性能，同时抗拉强度高，提高了纸袋的使用寿命，使用方法，可用于各种场合，减少了相关包装袋的使用，从而有效降低了对环境的污染。
附图说明
图1为本发明的结构示意图。
其中：1、纸袋本体，2、纸袋底部，3、内膜，4、外膜，5、折叠线，6、提手孔，7、加强层。
具体实施方式
下面结合附图说明对本发明做进一步地说明。
如图1所示一种复合型纸袋，包括纸袋本体1、外膜4、内膜3和纸袋底部2，纸袋本体1与纸袋底部2相连，纸袋本体1内侧设有内膜3，所这纸袋本体1外侧设有外膜4，纸袋本体1上设有折叠线5，折叠线5下方设有提手孔6，提手孔6外围设有加强层7。纸袋本体1和纸袋底部2为一体结构，内膜3为聚乙烯材料，外膜4为有机硅树脂材料制成，纸袋底部2设有硬质木架。
本发明所提出的纸袋，设计合理，结构新颖，具有良好的防潮、耐磨性能，同时抗拉强度高，提高了纸袋的使用寿命，使用方法，可用于各种场合，减少了相关包装袋的使用，从而有效降低了对环境的污染。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
