Production process of degradable paper-plastic packaging bag

Abstract

The invention relates to a production process of a degradable paper-plastic packaging bag. The production process mainly comprises the following steps of material preparation, blow molding operation,printing operation, composite treatment, bag making operation, slitting operation and other various procedures. A paper-plastic bag composite device comprises a bottom plate, a roll feeding device, acleaning device, a glue spraying device, an unwinding device, an abutting device and a winding device. The production process can solve the following problems existing during compounding of an existing degradable paper-plastic packaging bag that a, during compounding of a traditional paper-plastic packaging bag, due to the fact that glue spraying is not uniform, the utilization rate of the glue isreduced, the compounding quality of the paper-plastic packaging bag is poor, raw materials of the paper-plastic packaging bag are wasted, and the production efficiency of the paper-plastic packagingbag is affected; and b, during compounding of the existing paper-plastic packaging bag, compounding deviation often occurs, the compounding quality of the paper-plastic packaging bag is reduced, the production quality of the paper-plastic packaging bag is further affected, and the compounding efficiency and quality of the paper-plastic packaging bag can be improved.

Description

technical field [0001] The invention relates to the technical field of packaging product production, in particular to a production process for degradable paper-plastic packaging bags. 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. Degradable paper-plastic packaging bags came into being. Degradable paper-plastic packaging bags The bag is also called a three-in-one composite paper bag, which is composed of a plastic layer and a paper layer.
