What is the difference between biodegradable plastic bags and recycled plastic bags? Which
Biodegradable plastic bags are those that completely degrade to carbon dioxide, methane gas, water, acidified carbonates, etc. in a special scenario or in a natural environment that is not harmful to the environment. As a new type of fiber material, biodegradable plastic bags include many different types, and the key technology is in continuous development trend.
What is the difference between biodegradable plastic bags and recycled plastic bags?
In terms of raw materials, biodegradable plastic bags can come from both petrochemical raw materials, but also from biomass fuel raw materials.
From the degradation principle, biodegradable plastic bags contain microbial degradation, photodegradation, air oxidation degradation these.
From the degradation of the actual effect, biodegradable plastic bags can be divided into "full" degradation and "part" of the degradation.
The key effect of degradable plastic bags is to reduce the utilization rate of non-degradable plastic products to the environment can not produce "white waste", in addition can also give the environment a stronger sustainable development concept of opportunities to improve the quality of the environment and reduce the environmental development trend of work pressure, improve the development trend of life.
Biodegradable plastic bags have their advantages in performance, applicability, degradability, and safety factor. In performance, biodegradable plastic bags can do or in some special industries beyond the performance of traditional plastic; in application, biodegradable plastic bags have similar application performance and environmental health performance with similar traditional plastic; in degradability, biodegradable plastic bags in the application, can be in the course of environmental (special microbial strains, temperature, environmental humidity) faster degradation, and become easy to be used by the environment Debris or non-toxic vapor, reducing the harm to the environment; in the safety factor, biodegradable plastic bags degradation process or residual chemicals caused by the environment is not harmful, not easy to endanger the survival of people and other microorganisms. And at this stage to replace the traditional plastic of the greater obstacle, but also biodegradable plastic defects make its product cost higher than similar traditional plastic or recycled plastic. Therefore, in packaging, agricultural land film and other applications for a short period of time, can not be acquired to separate out, the performance requirements are not high, the residue composition of the provisions of high, biodegradable plastic bags have the advantage of replacing the main use.
Recycled plastic bags is the plastic raw materials regained after the production and processing of waste plastics according to the preparation of treatment, melting granulation, modified materials and other physical or organic chemical solutions.
The greater advantage of recycled plastic bags is that the price is more cost-effective than brand-new materials and biodegradable plastic bags, and can be based on different performance must be produced and processed only a certain level of plastic characteristics, and the production of matching goods.
In the event that the recycling system is not too frequent, the recycled plastic bag can maintain similar performance to the conventional plastic bag, or can maintain smooth performance depending on how the recycled pellets are mixed with the new material. However, after several cycles of the recycling system, the performance of the recycled plastic degrades significantly or reaches a level where it cannot be used.
In addition, it is difficult to maintain stable sanitary performance of recycled plastic bags under the premise of ensuring reasonableness. Therefore, recycled plastic bags are rarely used in the recycling system, and the environmental health performance of the industry is not too high.
Compared to recycled plastic bags, biodegradable plastic bags have outstanding advantages in terms of performance and environmental protection, and today, biodegradable plastic bags have also become an important windfall in the market!
Renewable plastic bags are highly sought after in Austria
Berndorf, a small town adjacent to the Austrian capital of Vienna, for the recent launch of an environmental campaign called "I shop in Berndorf" (Ishopin Berndorf) and the attention.
What is the difference between biodegradable plastic bags and recycled plastic bags? Which plastic bags should we use?
Despite its small size and population, Berndorf is remembered by domestic and international visitors for its environmentally friendly shopping. In Berndorf, people use the "Berndorf plastic bag", named after the city, to do their shopping. These shopping bags are made of renewable woven plastic and can be recycled many times.
According to local media reports, Berndorf shopping bags, also known as CB*star plastic bags, developed exclusively by Starlinger, a well-known Austrian plastic bag manufacturer.
Starlinger said, CB*star renewable plastic woven bags can be sold, and all consumers in Berndorf unanimously approved, but also thanks to the "Ishopin Berndorf" the initiator of the campaign Sandra Kreger.
As the owner of an Italian delicatessen in Berndorf, Sandra Kreger was the first to use the new plastic woven bags and received good feedback from the market. So the idea of helping Starlinger to promote this plastic bag citywide in Berndorf came to Kreger's mind.
"CB*star plastic bags are very light, but of high quality, capable of carrying up to 25 kg and can be used again and again. It is the ideal environmentally friendly shopping bag." Kreger said so.
In China, many companies in the plastics industry have also invested a lot of money in the development of biodegradable plastic bags, in order to meet the new market demand. Among them, the company Cardid has developed biodegradable polymer materials made of plastic products belong to biodegradable plastic.
