Abstract

The invention relates to a production process of plastic woven bags. The process comprises the steps of raw material proportioning, raw material mixing, filament drawing, fabric weaving, printing, kerf cutting, examining and packaging. The production process has the advantages that heat stabilizer and light stabilizer are added to raw materials to prevent high temperature creep and aging of the plastic woven bags, packing materials with an appropriate amount are added to make the tensile strength of ribbon-like filaments stronger, the main ingredient of the packing materials is calcium carbonate, the stiffness of the ribbon-like filaments is improved, the temperature of the cooling water is appropriate, thin films are soft when the thin films are taken out of the water, the thin films areeasy to flatten , and the width of the adopted ribbon-like filaments is higher, so that the surfaces of the woven bags are more flatten, the production efficiency of a circular weaving machine is improved, and integrated sewing and packaging of a packaging machine are adopted to improve the production efficiency.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a production process of a plastic woven bag. Background technique [0002] With the rapid development of society and technology, plastic woven bags have played an irreplaceable role in people's lives, but the common plastic woven bags on the market can meet the performance to a certain extent, but some plastic woven bags stretch The strength and stiffness are low, and it is prone to creep when encountering high temperature, and it is prone to aging phenomenon under light conditions.
