Problems solved by technology

Common plastic bottles currently used generally use polyester, polyethylene, and polypropylene materials. Polyester has the advantages of high strength, good wear resistance, and light weight, but it has poor melt strength, slow crystallization speed, and poor dimensional stability. Meet the needs of rapid prototyping; polyethylene has the advantages of good toughness and high and low temperature resistance, but its disadvantage is that it is easy to deform; polypropylene material has the advantages of high surface strength, strong chemical stability, heat resistance and no deformation, but its disadvantage is toughness Poor, poor oxidation resistance, not wear-resistant
[0003] Secondly, in daily life, pathogenic substances such as bacteria and mold are ubiquitous, threatening human health at all times, and the common plastic bottle materials currently used are easy to nourish bacteria, resulting in the production of mineral water bottles that are easy to carry bacteria. Humans use plastic bottles with bacteria to hold mineral water, which will infiltrate the harmful components in the plastic components and the bacteria carried into the human body, and in serious cases, infection will occur
At the same time, with the widespread use of plastic bottles, the recycling of plastic bottles has become an urgent problem to be solved. The material of ordinary plastic bottles is difficult to degrade, which is easy to cause white pollution and cause damage to soil and crops.
