Situation, trend and policy interpretation of PLA degradable plasticsSituation, trend and policy interpretation of PLA degradable plastics
Corn starch - based biodegradable materials related topics.
Let's start with the plastic limit decree: in 2020, the National Development and Reform Commission announced an opinion on further strengthening the treatment of plastic pollution, which has been read more than 100,000 times. Here are a few things to keep in mind:
The import of waste plastics will be banned.
Prohibit or restrict the use of some plastic products
Non-degradable plastic bag
Disposable plastic tableware
Hotels, hotels disposable plastic supplies
Express plastic package
By the end of 2020, the production and sale of disposable foamed plastic tableware and disposable plastic cotton swabs will be banned. The production of daily chemical products containing plastic microbeads is prohibited.
What materials are being promoted and promoted?
Promotion and Application of Degradable packaging film (bag)
In shopping malls, supermarkets, pharmacies, bookstores and other places, the use of environment-friendly cloth bags, paper bags and other non-plastic products and biodegradable shopping bags will be promoted. Self-service and intelligent delivery devices will be encouraged to facilitate people's lives.
Promote the use of fresh products degradable packaging film (bag). We will establish a centralized system for purchasing and selling shopping bags in market s. Promote the use of straw mulch meal boxes and other bio-based products and biodegradable plastic bags that meet the performance and food safety requirements in the field of food and take-out. In key areas covered with film, combined with agronomic measures to promote the large-scale degradable plastic film.
It is known to all that the harm of white garbage (refers to disposable plastic materials that cannot be degraded) is obvious to all. The main harm of white pollution lies in visual pollution and potential harm. In cities, tourist areas, water bodies and roads scattered waste plastic packaging to people's visual stimulation, affect the overall beauty of the city, scenic spots, damage the city appearance, landscape, resulting in "visual... .
Polylactic acid (PLA) is a biodegradable resin used in packaging fruits, vegetables, baked goods and other materials. Polylactic acid is usually called corn plastic. It is made of L-lactic acid produced from corn cassava through polycondensation, pyrolysis, purification, polymerization and other technological processes, and is a new biodegradable material of AVIC. It is a technological and environmental protection product concerned with development. Widely used in electronic products shell, auto parts, medical equipment, auxiliary fiber, agricultural plastic film, food packaging, disposable tableware and other fields. With unlimited development space and future, it is a new material to be promoted vigorously in the new era.
PLA PLA sheet extrusion line is suitable for the production of PLA and modified materials. PLA is derived from plant resources and can be extruded directly in English. The extrusion equipment is equipped with a solution metering pump for quantitative extrusion. The speed and pressure control make the thickness of the sheet more uniform, the roller drives independently and the linear speed is synchronous. Equipped with multiple extruders, it can produce two or more layers of degradable materials.
