Environment-friendly packaging bag with good toughness

Abstract

The invention discloses an environment-friendly packaging bag with good toughness. The bag body of the packaging bag is made of a material film; the material film is obtained by mixing first master batch particles with second master batch particles; the first master batch particles contain the following components in parts by weight: 40-65 parts of polyolefin plastic, 5-8 parts of chitosan, 3.5-4.5 parts of methylisothiazolinone, 2-3 parts of bamboo charcoal micro powder, 4-6 parts of methyl phenyl polyborosiloxane, 2.0-2.5 parts of polysebacic polyanhydride, 5.5-7.5 parts of N-phenyl maleimide, 5-7 parts of hexamethoxymethyl melamine resin, 8-10 parts of diethyl malonate, 6-8 parts of decabromodiphenyl ether, 6-8 parts of dibasic lead phosphite, 0.1-0.2 parts of coupling agent, 4-6 partsof 3-hydroxybenzoic acid and 1-2 parts of lauryl sulfate. The packaging bag disclosed by the invention has the advantages that the packaging bag can be quickly degraded in the buried state; the packaging bag has good strength, optical performance and toughness at the same time; the air permeability and the moisture permeability of the packaging bag are reduced; and convenience is brought to the packaging of various articles, use by staff and the preparation.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to an environment-friendly packaging bag with good toughness. Background technique [0002] Plastic packaging bag is a kind of packaging bag that uses plastic as raw material to produce various supplies in daily life. It is widely used in daily life and industrial production, but the convenience at this time brings long-term harm. Commonly used plastic packaging bags are mostly made of polyethylene film, which is non-toxic, so it can be used to hold food. There is also a kind of film made of polyvinyl chloride, polyvinyl chloride itself is non-toxic, but the additives added according to the purpose of the film are often harmful substances to the human body and have certain toxicity. Therefore, this kind of film and the plastic bag made of this film are not suitable for holding food. In particular, ultra-thin plastic packaging bags are easily damaged, and most of them are di...

Problems solved by technology

[0004] If the existing degradable plastic packaging bags are buried in garbage or soil, the degradation effect is not obvious, and the existing degradable plastic packaging bags have increased air permeability and poor tensile strength, which are not conducive to degradable plastics. The use of packaging bags restricts the development of degradable plastic packaging bags. Therefore, we propose an environmentally friendly packaging bag with good toughness to solve the above problems
