Problems solved by technology

[0003] At present, the existing woven bags usually have the following defects in the production and processing process: 1. When applying glue to the woven cloth, the glue application effect is poor and the application is uneven, resulting in inconsistent thickness of the glue solution and prone to missing coating; 2. In the process of pressing the woven cloth and the sticker, there are a lot of air bubbles between the woven cloth and the sticker due to incomplete pressing; this affects the use of the later woven bag

Abstract

The invention provides a preparation process of a composite plastic bag. The composite plastic bag is prepared through cooperation among a clamping frame, a pressing device, a gluing device and a gluecoating device. The process can solve the problems for an existing woven bag during a production and processing that 1 the glue coating effect is poor when the woven bag is subjected glue coating, coating is uneven, the thickness of a glue solution is inconsistent, and the coating leakage phenomenon is prone to occur; and 2, a large quantity of air bubbles exist between woven fabric and a stickerin a process of woven fabric and sticker pressing due to incomplete pressing, and the use of the later woven bag is affected.

Description

technical field [0001] The invention relates to the technical field of woven bags, in particular to a preparation process of a composite plastic bag. Background technique [0002] Woven bag, also known as snakeskin bag, is a kind of plastic bag used for packaging products, and its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. Plastic woven bags are composed of polypropylene bags and polyethylene bags according to the main materials; according to the sewing method, they are divided into seamed bottom bags and seamed bottom bags. At present, woven bags are widely used as packaging materials for fertilizers, chemical products and other items. Since the development of woven bags, the products have developed rapidly and have formed a series of products with various varieties and complete specifications and sizes. [0003] At present, the existing woven bags usually have the following defects in the production and processin...
