Packaging bag capable of being conveniently recovered

Abstract

The invention has the design goal of providing a packaging bag capable of being conveniently recovered. The packaging bag comprises a front piece, a back piece and sewing threads, wherein each of the front piece and the back piece is nonwoven fabric made of pp (polypropylene); a transparent pp thin film is connected onto each of the inner surface and the outer surface of the front piece and the back piece; the sewing threads are pp threads. The packaging bag has the advantages that the front piece and the back piece are sewed into a bag body through the sewing threads; the front piece and the back piece in the technical scheme are nonwoven fabric made of pp materials; the transparent pp thin film is connected onto the inner surface and the outer surface of the front piece and the back piece, so that on one hand, vapor and grease can be well blocked; a dampproof effect and an air-tight effect are ensured; in addition, the sewing threads are also pp threads, so that after being used and recovered, the whole bag body does not need to be dismounted for separated recovery; the direct integral recovery can be realized; the required technical scheme can be well realized.

Description

technical field [0001] The present invention relates to a packing bag, more specifically relates to a packing bag which is easy to recycle. Background technique [0002] As a tool, packaging bags are widely used in production and life. Among them, there is a paper kraft bag in the prior art, which is widely used in various fields for packaging cement, flour or other chemical products. . [0003] Among them, the invention patent with the application number CN95233065.2 in the prior art discloses a technical solution: it relates to a titanium dioxide packaging bag powered by compressed air. Its characteristics are: the inner kraft paper bag of square tube is connected with the outer paper-plastic composite bag through the adhesive layer, and the length of each side of the inner kraft paper bag is 2-3mm larger than that of the outer paper-plastic composite bag. The top surface and the ground of the inner kraft paper bag are respectively provided with a kraft paper reinforceme...

AI Technical Summary

Problems solved by technology

[0004] The packaging bag in the above technical solution also uses kraft paper like most of the kraft paper bags in the existing market. However, the paper will produce a large amount of industrial waste water in the processing project, causing great pollution, and will have a great impact on the environment. The most important The most important thing is that a packaging bag is composed of multiple materials, which will have a great impact on subsequent recycling. Recyclers have to disassemble the packaging bags according to different materials, and then process them uniformly, which is undoubtedly very cumbersome
