Production technology of plastic weaving bag with damp prompting function and recycling method thereof

Abstract

The invention provides a production technology of a plastic weaving bag with a damp prompting function and a recycling method thereof. The plastic weaving bag with the damp prompting function sequentially comprises an inner weaving bag, a damp prompting outer layer and a transparent waterproof layer from interior to exterior. The production technology comprises the following steps of S1, preparingof allochroic silicagel; S2, blending and drying; S4, preparing of the damp prompting outer layer: adding polypropylene particles, EVA (ethyl vinyl acetate), a transparent agent and light-blue allochroic silicagel particles into a co-extrusion blow molding film machine, heating, melting, and performing blow molding to form a cylindrical damp prompting outer layer; S4, weaving; S5, manufacturing of the bag. The production technology of the plastic weaving bag with the damp prompting function and the recycling method thereof aim at providing a novel weaving bag with the advantages that the dampstate of objects in the weaving bag and the damp part of the weaving bag can be visually judged; the weaving bag can be recycled; the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of processing plastic woven bags, in particular to a production process and a recovery method of a plastic woven bag with a moisture indication. Background technique [0002] Plastic woven bags are made of polypropylene as the main raw material, which are extruded, drawn, and then weaved, woven, and bag-made. Polypropylene is a translucent, semi-crystalline thermoplastic with high strength, good insulation, low water absorption, high heat-forming temperature, low density, and high crystallinity. It is the main raw material for woven bags. Woven bags are widely used to hold chemicals, grain, flour, cement and other products. Existing plastic woven bags only play the role of dressing. When the items in the woven bag are damp and deteriorated, it is impossible to judge from the outside of the woven bag. You can only open the woven bag to judge whether the item is damp through the contents of the woven bag. Fo...

AI Technical Summary

Problems solved by technology

Existing plastic woven bags only play the role of dressing. When the items in the woven bag are damp and deteriorated, it is impossible to judge from the outside of the woven bag. You can only open the woven bag to judge whether the item is damp by opening the woven bag. For the wet parts of the goods, there are some goods that are not damp at the top but damp at the bottom. Opening the woven bag can only judge the degree of dampness of the upper part of the bag, but cannot judge the degree of dampness of the goods in the lower part of the woven bag
