Dampness resisting plastic bag and preparation method thereof

Abstract

The invention discloses a dampness resisting plastic bag and a preparation method thereof, and belongs to the field of plastic. The dampness resisting plastic bag comprises an insulation layer and a dampness absorbing layer, the dampness absorbing layer is arranged on the inner side of the insulation layer and comprises, by weight, 70-85 parts of low density polyethylene, 30-40 parts of polypropylene, 22-24 parts of polycarbonate resin, 8-10 parts of tea leaves, 4-6 parts of ceiba fibers, 5-7 parts of manila hemp fibers, 2-4 parts of nano molybdenum disulfide, 3-5 parts of nano titanium oxide,1-3 parts of a plasticizer, 2-4 parts of an antibacterial agent and 1-3 parts of an optical stabilizer. The dampness resisting plastic bag has the advantages that external moisture can be isolated, moisture entering the plastic bag can be timely absorbed to avoid food deterioration and prevent items from being mildewed.

Description

technical field [0001] The invention belongs to the field of plastics, and in particular relates to a moisture-proof plastic bag and a preparation method thereof. Background technique [0002] Plastic bags can be used for the inner and outer packaging of various small items (accessories, hardware, toys). Plastic bags made of food-grade raw materials can store various small foods, tea, seafood, etc., moisture-proof, anti-odor, waterproof, insect-proof, and prevent things from scattering; plastic bags can also be used for packaging clothing and other daily necessities, and are widely used . The anti-static plastic bag can be produced by adding anti-static masterbatch in the blown film production, which is generally used in the electronics industry. However, the moisture-proof effect of the current plastic-sealed bag is not good. When the air humidity is high, the plastic-sealed bag is sealed again after opening the plastic-sealed bag, and water droplets are easy to accumulat...

AI Technical Summary

Problems solved by technology

However, the current plastic-sealed bag has poor moisture-proof effect. When the air humidity is high, the plastic-sealed bag will be sealed again after opening the plastic-sealed bag, and water droplets will easily accumulate in the plastic-sealed bag, which will affect the quality of food or articles in the plastic-sealed bag.
