Abstract

The invention provides a composite plastic woven bag, and belongs to the technical field of plastic woven bag processing. The composite plastic woven bag consists of a water absorbing layer, a woven layer and a protection layer in sequence from inside to outside, wherein the water absorbing layer is prepared from the following raw materials in parts by weight: 55 to 75 parts of polyurethane particles, 20 to 30 parts of polyethylene and 7 to 15 parts of banana fiber; the woven layer is prepared from the following raw materials in parts by weight: 60 to 70 parts of polypropylene particles, 20 to30 parts of polyethylene and 5 to 10 parts of coolmax fiber. The composite plastic woven bag plays a better role in preventing moisture and insulating air for the external environment, the inside ofthe woven bag is kept in a dry, low-oxygen and high-carbon-dioxide state, water and moisture are prevented effectively, air and oxygen are insulated, deterioration of stored materials can be delayed,and the storage time of the materials is prolonged.

Description

technical field [0001] The invention relates to the technical field of plastic woven bags, in particular to a composite plastic woven bag. 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 making plastic woven bags. However, the polypropylene material is impervious to water and air, and it is easy to accumulate moisture during the storage process of the material, causing the material to become moldy and rancid, and the quality is reduced; and polypropylene is easy to age and degrade, lose its original transparency, and the surface turns yellow and fades. [0003] The safety of storage of water-containing materials such as grain is not only re...
