Now the price gap between ordinary plastic bags and degradable plastic bags is generally about 2-3 times because many people think that replacing ordinary pe plastic bags with degradable plastic bags will raise our living costs, which is not cost-effective.
Indeed, from an economic point of view, it is not yet time for degradable plastic bags to replace ordinary PE plastic bags, but from the perspective of environmental protection and the long-term development of human beings, this step can only be accelerated without waiting.
The white pollution caused by ordinary pe plastic bags has brought huge problems to humans, animals, and the natural environment for all to see. Eliminating white pollution is also the common goal of all mankind.
How to achieve this goal? In addition to the plastic restriction orders of various governments, it is important to have alternative products. The degradable plastic bag came into being. It is mainly made of PLA (polylactic acid) and PBAT (copolymer of butylene terephthalate and butylene terephthalate). PLA is a blend of two materials. Blending with PBAT improves the toughness of PLA and shows the complementarity of the two, but the simple blending of the two is incompatible. Capacitance. Through a series of technological processes such as film blowing, the products produced are relatively stable and suitable for packaging in various industries.
To improve people's quality of life, the environment must follow up. Degradable plastic bags can be degraded into water and carbon dioxide in 180 days under industrial composting conditions, which is a key step in solving white pollution.
