Embodiment 1

[0017] The production process of the plastic woven bag includes the steps of material preparation-drawing-weaving-film covering-cutting-printing-sewing-packing,

[0018] The preparation of materials is to prepare 60 parts of polypropylene, 50 parts of polyethylene, 1 part of polyethylene wax, 5 parts of glyceryl stearate, 1 part of pp impact resistance agent, 22 parts of filler, 0.5 parts of light stabilizer, antioxidant Put 0.3 parts into a dry mixer according to the proportion and stir, and dry for 20 minutes at a temperature of 20°C, then raise the temperature to 50°C, and dry for another 20 minutes. The filler is composed of kaolin, diatomaceous earth, talcum powder and mica The powder is mixed according to the ratio of 3:5:1:1.

[0019] In the wire drawing, the dried material enters the extruder, and is heated to 150°C through the seven-stage twin-screw of the barrel, so that it is well plasticized and transported to the mold for extrusion molding. After being cooled and ...

Abstract

The invention discloses a plastic woven bag production process, and belongs to the technical field of woven bags. The problem that woven bags produced in the prior art are poor in heat resistance andweather resistance, poor in toughness and rigidity, and high in cost is solved. The production process comprises the steps of material preparation, wire drawing, weaving, film covering, cutting, printing, sewing and packaging in sequence, wherein the material preparation comprises putting raw materials into a drying stirrer according to a ratio, stirring the materials, drying the materials at 20-35 DEG C for 20-30 min, then raising the temperature to 50-60 DEG C, and drying the materials for 20-30 min; and the raw materials comprise polypropylene, polyethylene, polyethylene wax, glyceryl stearate, a pp anti-impact agent, a filler, a light stabilizer and an antioxidant, and the raw materials comprise polypropylene, polyethylene, polyethylene wax, glyceryl stearate, a PP anti-impact agent, afiller, a light stabilizer and an antioxidant. The process can be used for producing plastic woven bags.

Description

technical field [0001] The invention relates to a production process of a plastic woven bag, which belongs to the technical field of woven bags. Background technique [0002] Plastic woven bags are widely used in the field of life and production because of their lightness, thinness, firmness, waterproof, non-mildew, and low price. The existing plastic woven bags are mainly made of polypropylene and polyethylene resin, and filled with Agents and various additives are extruded and drawn into flat filaments, and then woven and bagged. This type of traditional plastic woven bag has poor heat resistance and weather resistance and short service life; in addition, its filler is generally calcium carbonate, although calcium carbonate can comprehensively improve the stability and fluidity of plastic woven bags, but its The toughness and rigidity are poor, and the surface of the woven bag is dull. Contents of the invention [0003] The purpose of the present invention is to overco...
