What is the difference between degradable plastic bags and recycled plastic bags?
Degradable plastic bags refer to the complete degradation of carbon dioxide, methane, water, mineralized inorganic salts and other environmentally harmless substances under certain circumstances or in the natural environment. As a new type of polymer material, degradable plastic bags include many types, and the technical route is also under continuous development.
From the perspective of raw materials, biodegradable plastic bags can be derived from petrochemical raw materials or biomass materials.
From the perspective of degradation mechanism, degradable plastic bags include biodegradation, photodegradation, oxidative degradation, etc.
From the perspective of degradation effects, degradable plastic bags can be divided into "full" degradation and "partial" degradation.
The main function of degradable plastic bags is to reduce the indispensable "white pollution" caused by the use of non-degradable plastic products, and it can also give the environment better opportunities for sustainable development, improve the quality of the environment, and reduce the environment. The pressure of development benefits human development.
Degradable plastic bags have their advantages in performance, practicality, degradability and safety. In terms of performance, biodegradable plastic bags can reach or exceed the performance of traditional plastics in certain specific areas; in terms of practicality, biodegradable plastic bags have similar application performance and hygienic performance to similar traditional plastics; in terms of degradability, they can After the degradable plastic bag is used, it can be degraded quickly in the natural environment (specific microorganisms, temperature, humidity), and become fragments or non-toxic gases that are easily used by the environment, reducing the impact on the environment; in terms of safety, it can be The substances produced or left over from the degradation process of degradable plastic bags are harmless to the environment and will not affect the survival of humans and other organisms. At present, the biggest obstacle to replacing traditional plastics is also the disadvantage of biodegradable plastics in that their production costs are higher than similar traditional plastics or recycled plastics. Therefore, in applications such as packaging, agricultural film, etc., which have a short use time, are difficult to recycle and separate, have low performance requirements, and have high impurity content requirements, degradable plastic bags have more alternative advantages.
Recycled plastic bags refer to plastic raw materials obtained after processing waste plastics through physical or chemical methods such as pretreatment, melt granulation, and modification. The biggest advantage of recycled plastic bags is that they are cheaper than new materials and biodegradable plastic bags. According to different performance requirements, only certain attributes of plastic can be processed and corresponding products can be manufactured. In the case of not too many cycles, recycled plastic bags can maintain similar performance to traditional plastic bags, or they can maintain stable performance by mixing recycled materials with new materials. However, after many cycles, the performance of recycled plastics drops greatly, or to an unusable level. In addition, it is difficult for recycled plastic bags to maintain good hygiene performance under the premise of ensuring economy. Therefore, recycled plastic bags are suitable for areas where the number of cycles is small and the hygiene performance is not high.
By comparison, Shandong Haotaijia Environmental Protection Technology Co., Ltd., a professional flexible packaging manufacturer, believes that biodegradable plastic bags have more stable performance and lower recycling costs, and they are more suitable for applications such as packaging and agricultural films that have a short use time and are difficult to recycle and separate. It has the advantage of substitution; because recycled plastic bags have lower prices and production costs, they are more advantageous in application scenarios that are easy to sort and recycle, such as household appliances, building materials, and electrical appliances. The two complement each other. White pollution mainly comes from the packaging field, and biodegradable plastic bags have more room to play. With policy promotion and cost reduction, the future of biodegradable plastic bags has a bright future.
Shandong Haotaijia Environmental Protection Technology Co., Ltd. focuses on the production and sales of packaging bags of various materials. At the same time, "green production" is also one of the business philosophy of Shandong Haotaijia Environmental Protection Technology Co., Ltd.
