Abstract

The invention discloses a plastic packaging bag for packaging a fruit. The plastic packaging bag is prepared from the following raw materials in parts by weight: 40 to 70 parts of linear low density polyethylene, 20 to 40 parts of polyvinyl chloride, 15 to 25 parts of diaminotoluene, 15 to 20 parts of carbon fiber, 8 to 12 parts of titanium stearate, 10 to 20 parts of corn starch, 1 to 2 parts oftoughening agent, 20 to 30 parts of silicon carbide, 15 to 18 parts of polyethylene, 2 to 4 parts of lubricating agent, 3 to 4 parts of initiator, 0.1 to 1 part of toner and 1 to 3 parts of tetrabutyltitanate. The packaging bag provided by the invention is durable, has high toughness, can be used for loading a heavy object, is high in stability, moreover, adopts a filling material which is low inprice, is low in production cost and is relatively more easily accepted by the market.

Description

technical field [0001] The invention relates to a plastic packaging bag, in particular to a plastic packaging bag for packing fruits. Background technique [0002] Composite packaging plastic bags use synthetic resin or natural resin as the basic raw material, add (or not add) various plastic additives, reinforcing materials and fillers, and process them into molding or cross-linking curing molding under a certain temperature and pressure. solid materials or products. Plastic refers to a material that uses resin (or direct polymerization of monomers during processing) as the main component, plasticizers, fillers, lubricants, colorants and other additives as auxiliary components, and can be flow-formed during processing. It is a synthetic polymer compound that can change its shape freely. However, the existing plastic packaging bags have various disadvantages, especially the existing plastic bags have relatively large odor, insufficient strength and toughness. Contents of...
