Manufacturing method of environment-friendly paper-plastic packaging bag

Abstract

The invention relates to a manufacturing method of an environment-friendly paper-plastic packaging bag. The manufacturing method of the environment-friendly paper-plastic packaging bag mainly comprises the following steps of material preparation, blow molding operation, printing operation, composite treatment, bag manufacturing operation, slitting operation and other multiple processes. Paper-plastic bag slitting equipment used comprises a bottom plate, a slitting device, a roll feeding device, a conveying device and an abutting device. The manufacturing method of the environment-friendly paper-plastic packaging bag provided by the invention can solve the following problems existing in existing paper-plastic packaging bag slitting: a, when a traditional paper-plastic packaging bag is slit,a cutter is generally used for cutting the traditional paper-plastic packaging bag manually, cutting deviation often occurs when the paper-plastic packaging bag is cut manually, the production quality of the paper-plastic packaging bag is influenced, raw materials are wasted, workers are prone to fatigue in the cutting process, and the phenomenon that the workers are prone to being scratched occurs; and b, when existing paper-plastic packaging bag slitting equipment is used for slitting paper-plastic packaging bags, only single packaging bag can be cut out, and the slitting efficiency of thepaper-plastic packaging bags is reduced; and the slitting efficiency and the slitting quality of the paper-plastic packaging bags can be improved.

Description

technical field [0001] The invention relates to the technical field of packaging bag production, in particular to a manufacturing method of an environmentally friendly paper-plastic packaging bag. Background technique [0002] Existing packaging bags have been widely used in many fields. Traditional packaging bags are mainly made of plastic packaging bags. With the enhancement of people's awareness of environmental protection, more and more paper packaging bags appear in people's lives to reduce plastic packaging. The amount used to protect the environment, but the packaging performance of pure paper packaging is poor, and some functional plastics are needed to compound it to solve this problem. Paper-plastic packaging bags have also emerged at the historic moment. One-in-one composite paper bag is composed of plastic layer and paper layer. The two are usually bonded by molten plastic thermal lamination to form a paper-plastic packaging bag roll. After the paper-plastic pack...

[0002] Existing packaging bags have been widely used in many fields. Traditional packaging bags are mainly made of plastic packaging bags. With the enhancement of people's awareness of environmental protection, more and more paper packaging bags appear in people's lives to reduce plastic packaging. The amount used to protect the environment, but the packaging performance of pure paper packaging is poor, and some functional plastics are needed to compound it to solve this problem. Paper-plastic packaging bags have also emerged at the historic moment. One-in-one composite paper bag is composed of plastic layer and paper layer. The two are usually bonded by molten plastic thermal lamination to form a paper-plastic packaging bag roll. After the paper-plastic packaging bag roll is formed, it needs to be cut into individual paper. plastic bag

[0003] However, the following problems exist in the cutting of existing paper-plastic packaging bags: a. When cutting traditional paper-plastic packaging bags, it is usually cut by using a knife manually. Cutting deviations often occur, which affects the production quality of paper-plastic packaging bags, wastes raw materials, and workers are prone to fatigue during cutting, making manual scratches prone to occur; When the packaging bag is cut, only a single packaging bag can be cut out, which reduces the cutting efficiency of the paper-plastic packaging bag and can improve the cutting efficiency and quality of the paper-plastic packaging bag
