Preparation technology for environment-friendly high polymer material packaging bag

Abstract

The invention provides a preparation technology for an environment-friendly high polymer material packaging bag. The preparation technology comprises the following steps that a design drawing is drawn, a packaging bag printed object is prepared, surface treatment of the packaging bag printed object is performed, a plate roller is manufactured, a processing technology route is formulated, printingprocessing is performed, quality inspection is performed, compound treatment is performed, curing treatment is performed and bag making is performed. According to the preparation technology, through polyhydroxyalkanoate and fiber materials in the composition of the packaging bag printed object, the degradability of a packaging bag can be improved, meanwhile, the degradation period of the packagingbag is short, the packaging bag can react with water to be degraded when being covered or buried in the soil, so that the degradation efficiency of the packaging bag is improved, it is guaranteed that the degradation of the packaging bag is not affected by environmental factors, the pollution to the environment after the packaging bag is abandoned is reduced, the strength and the tension of the packaging bag can be improved through the compound treatment and the curing treatment, the quality problems of film curling, wrinkling, difficulty in bag making, peeling strength declination and bag making deformation of the packaging bag occurring in the subsequent bag making process are solved, and the quality of the packaging bag is improved.

Description

Technical field [0001] The invention relates to the field of packaging bags, in particular to a process for preparing environmentally friendly polymer material packaging bags. Background technique [0002] Packaging bags refer to bags used to pack various supplies, which make the goods convenient to transport and store in the production and circulation process. They are widely used in daily life and industrial production. The development of packaging bags has gone through four obvious stages: original packaging The bag stage, the big bag stage, the small bag stage, and now gradually enter a new stage of environmentally friendly (green) packaging bags. [0003] Most of the existing packaging bags are products made of polymer plastic materials. Polymer plastic materials are not easily degraded, and it takes hundreds of years to be completely decomposed. According to survey data, about 80% of used packaging bags In the end, it is transported to the garbage dumping area like general g...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing packaging bags are products made of polymer plastic materials. Polymer plastic materials are not easy to degrade, and it takes hundreds of years to be completely decomposed. According to survey statistics, about 80% of used packaging bags In the end, it is transported to the landfill area for treatment like general garbage. Only less than 7% of the packaging bags are recycled and recycled. The packaging bags that cannot be degraded for a long time are very polluting to the environment. After being exposed for about 3 months, the texture becomes thinner, and the strength decreases and then cracks into fragments. However, if the cracked fragments are covered or buried in the soil, they still cannot be completely reduced.
