With the wide spread and application of PP non-woven fabric, more and more people give up PE plastic bags and begin to pay attention to PP non-woven fabric, which is a more environmentally friendly material. Although PP non-woven fabric has recyclable and decomposable characteristics, it is still a kind of plastic, and the exploitation of its raw materials still has a certain impact on nature. Some countries, such as India, have already listed PP non-woven fabric as part of the prohibition. To solve this problem, Zhejiang Yanpeng non-woven machinery Co., Ltd. launched another new product: PLA polylactide spunbond non-woven production line.
What is PLA?
Polylactic acid (PLA) is a new type of bio based and renewable biodegradable material, which is made of starch material proposed by renewable plant resources (such as corn, cassava, etc.). Glucose was obtained from starch by saccharification, and then high purity lactic acid was produced by fermentation of glucose and certain bacteria. Then polylactic acid with certain molecular weight was synthesized by chemical synthesis. It has good biodegradability, can be completely degraded by microorganisms in the nature under specific conditions after use, and finally generate carbon dioxide and water, not polluting the environment, which is very beneficial to the protection of the environment, is recognized as environmentally friendly materials.
What are the applications of PLA nonwovens?
Extrusion-grade resin is the main market application of PLA. It is mainly used in the packaging of fresh fruits and vegetables in large supermarkets. This type of packaging has become an important member of the European market chain; secondly, it is used for packaging of electronic products that promote safety, energy saving and environmental protection. on. In these applications, PLA's high transparency, high gloss, high rigidity and other advantages are vividly reflected, and it has become the dominant direction of PLA applications. In addition, the application of extrusion-grade resin in horticulture has also begun to gain attention, and has been applied in fields such as slope greening and sandstorm control. Spunbond non-woven fabrics have been used in PLA non-woven fabrics. Because of the implementation of China's plastic restriction order, this non-woven fabric is more popular in the production of shopping bags. In the two fields of blown film and laminating film, because of some characteristic defects of PLA itself, the application situation is still being further explored. Some successful application cases are the modified use of PLA.
Absolute environmental protection has become the main reason why PLA non-woven fabrics can be popular in the market. Under the tide of world environmental protection, this new type of product will definitely receive more people's acceptance and love.
