Abstract

The invention relates to the technical field of packaging bag processing, and discloses a production and processing technology of a paper-plastic packaging bag. The production and processing technology needs to use a compounding device, and comprises the following steps that (1) material preparation is performed; (2) blow molding is performed, wherein plastic raw materials are added into a blow molding machine for blow molding to prepare a thin film, namely, a plastic layer; (3) printing is performed; (4) compounding is performed, wherein the plastic layer obtained after printing is compounded on raw-material paper through the compounding device, an adhesive of a glue coating roller is scraped through a scraper, the glue coating roller is used for perform glue coating on the raw-materialpaper, and then the plastic layer is pressed on the raw-material paper through a hot pressing roller for compounding to obtain a composite paper-plastic layer; (5) bag making is performed, wherein thecomposite paper-plastic layer firstly undergoes heat-seal edge sealing treatment, and then cold pressing shaping is performed on the sealed edge; and (6) slitting is performed, wherein the compositepaper-plastic layer is cut along the sealed edge to obtain the single paper-plastic packaging bag. According to the production and processing technology, the problem that in the prior art, glue coating is not uniform, and long-term use is performed, so that the adhesive becomes hard, and then the compounding effect is relatively poor can be solved.

Description

technical field [0001] The invention relates to the technical field of packaging bag processing, in particular to a production and processing technology of a paper-plastic packaging bag. Background technique [0002] Traditional packaging bags are mostly made of plastic. With the enhancement of people's awareness of environmental protection, more and more paper packaging is used to reduce the amount of plastic and protect the environment; but the packaging performance of pure paper packaging is poor, such as no heat seal Performance, can not be bagged, is not conducive to large-scale mechanized production, poor anti-oil pollution, etc., it is necessary to compound some functional plastics with it to solve this problem, and paper-plastic packaging bags came into being. The paper-plastic packaging bag, also known as the three-in-one composite paper bag, is composed of a plastic layer and a paper layer. The two are usually bonded by molten plastic thermal lamination. In the pro...
