Problems solved by technology

During the preparation process of packaging materials, a lot of waste gas, waste water and waste residue will also be generated. In addition, many of the prepared packaging materials are not environmentally friendly. Many packaging materials themselves have a large pollution to the environment and are not easy to decompose.

Abstract

The invention discloses a stretch-resistant composite packaging material and a preparation method thereof. The stretch-resistant composite packaging material is prepared by using low-density polyethylene, sodium carboxymethyl starch and butyl methacrylate as the main components and adding propylene glycol alginate, a hexamethoxymethyl melamine resin, microcrystalline cellulose, beta-cyclodextrin, dicyclohexylamine nitrite, anilinomethyl triethoxy silane, isoborneol acrylate, rosin sodium soap, activated carbon, zinc stearate, nano titanium dioxide, a plasticizer and a coupling agent. The preparation method comprises the following steps: thermostatic water bath treatment, centrifugal separation, vacuum drying, grinding refinement, microwave treatment, compounding, plasticizing, melt extrusion, hot pressing and the like. The composite packaging material has the advantages of favorable stretch resistance, favorable flexing resistance and low flammability, can satisfy the industrial requirements, and has favorable application prospects.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a stretch-resistant composite packaging material and a preparation method thereof. Background technique [0002] Packaging materials refer to the materials used to make packaging containers, packaging decoration, packaging printing, packaging and transportation to meet product packaging requirements, including metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, Main packaging materials such as chemical fibers and composite materials, and auxiliary materials such as coatings, adhesives, strapping tapes, decorations, and printing materials. Among the main packaging materials, paper packaging materials, plastic packaging materials, metal packaging materials and glass packaging materials are the most widely used categories. [0003] With the rapid development of the economy, the environmental pollution caused by industrialization is also increasing. Du...
