PLA fully degradable plastic bags, how much do you know?

  The plastic restriction order from Since its implementation in 2008, the annual growth of plastic products has decreased from 20% to less than 3%, but pollution remains severe, and the increase in plastic consumption has largely offset the actual achievements of plastic restriction. The previous plastic restriction order was mainly through price leverage and cultural promotion to reduce the use of plastic products, but it still couldn't stop the extensive use of heavily polluting plastic bags. What's out this time is the prohibiting the use of ， PLA fully degradable plastic bags have become the choice to solve the problem of white pollution, becoming a substitute for traditional plastic bags. So about PLA fully degradable plastic bags, how much do you know? Today, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will take you closer to PLA fully degradable plastic bags.

  Its material, PLA fully degradable plastic bag What is PLA, and what is it composed of?

  PLA is a polymer (polylactic acid) composed of small lactic acid units. Lactic acid is an organic acid that plays an important role in our daily lives. The yogurt we usually drink or anything with glucose can be converted into lactic acid, and the lactic acid for PLA consumables comes from corn, made from starch raw materials extracted from corn.

Currently PLA is the most common degradable plastic bag material one of with a unique characteristic : material one of, its raw materials come from nature. "

• PLA fully degradable plastic bags-- What does PLA degradation speed depend on?
• 

  The biodegradation process and its duration depend largely on the environment. For example, heat, humidity, and microorganisms are factors influencing PLA fully degradable plastic bags three necessary factors for degradation speed. PLA degrades fastest in high-temperature environments with abundant microorganisms. Burying PLA fully degradable plastic bags deep in the soil, can show signs of decay within 6 months. While PLA fully degradable plastic bags at room temperature and pressure, it takes longer to degrade. In an ordinary room, PLA fully degradable plastic bag degradation will last for a long time. Sunlight does not accelerate biodegradation (except for heat), UV light will only cause the material to lose color and become pale, which is the same effect as most plastics.

  PLA is one of the most common degradable plastics, a polymer obtained by polymerizing lactic acid as the main raw material. The PLA production process is pollution-free, and the product is biodegradable. After use, PLA can be composted, degrading into carbon dioxide and water at temperatures above 55°C or under the action of oxygen and microorganisms, achieving material circulation in nature without impacting the environment. Currently, the production of polylactic acid mainly uses the lactide ring-opening polymerization process, where lactic acid is first dehydrated to form oligomers, then depolymerized to form lactide, and then ring-opening polymerized to obtain polylactic acid. PLA also has reliable biocompatibility, biodegradability, good mechanical properties, and easy processability, widely used in packaging, textile industry, agricultural film, and biomedical polymer industries. The disadvantage of PLA is that the degradation conditions are relatively strict. However, since PLA has a relatively low cost in bio- fully degradable plastic bag material it has a relatively low cost, PLA consumption ranks among the top.
