The utility model relates to the technical field of composite film, in particular to a composite film with two-dimensional code and a vacuum compression bag with two-dimensional code. The composite film with two-dimensional code comprises a surface layer and an inner layer; the surface layer is provided with a transparent two-dimensional code region; the inner surface of the two-dimensional code region of the surface layer is printed with two-dimensional code layer and a substrate layer covering two-dimensional code layer in turn; the inner layer is covered with the substrate layer and compounded with the inner surface of the surface layer to form a composite film. In this scheme, the surface layer is an external layer, and the two-dimensional code region of the surface layer is a transparent region, so the two-dimensional code pattern in the two-dimensional code layer can be easily recognized from the outside; the two-dimensional code layer is covered with a substrate layer, which makes the outline of the two-dimensional code pattern more obvious and easier to be recognized; and the two-dimensional code layer is simultaneously recognized by the surface layer and the inner layer. The overlay protection can avoid the problem that the two-dimensional codes can not be identified because of the friction loss, and the composite film with two-dimensional codes in the present embodiment has simple structure, no complex processing technology, low production cost and strong practicability.
【技术实现步骤摘要】
带二维码的复合膜和带二维码的真空压缩袋
本技术涉及复合膜
,特别是涉及一种带二维码的复合膜和带二维码的真空压缩袋。
技术介绍
包装袋作为人们生活的必需品,常被用于收纳各种物品。随着社会的发展,现今的大部分的包装袋已经不再单纯只具备收纳功能了,人们将各种信息印刷在包装袋上,使得包装袋能够携带信息,不仅具备收纳物品功能,同时还可以实现广告宣传、防伪溯源、分类标识和信息传递等功能。二维码是近几年来广为流行的一种编码,相比于条形码能够携带更多的信息,并且具有占用面积小的优点,常用于印刷在包装袋上以承载更多信息。同时,为了防止出现二维码被摩擦而造成难以识别的问题,曾提出过一种包装袋,包括塑料表层、涂布在塑料表层下表面的标识附着层、印刷在标识附着层下表面的二维码标识层、喷涂在二维码标识层下表面的支撑层、塑料底层、条码标识层和保护层,然而这种带二维码的包装袋的结构复杂,因此制作成本较高。
技术实现思路
基于此,有必要针对目前带二维码的包装袋的结构复杂,因此制作成本较高的问题,提供一种带二维码的复合膜和带二维码的真空压缩袋。为解决上述技术问题,本技术采用了下述技术方案:一种带二维码 ...
