What Are The Classifications Of Degradable Plastic Bags?
2023-04-08
Degradable Plastic Bags refer to plastic bags that have certain degradable properties and can be decomposed, degraded or biodegraded relatively quickly in the natural environment. Compared with traditional plastic bags, degradable plastic bags can be decomposed by microorganisms into natural substances such as water and carbon dioxide after being affected by the natural environment, thereby reducing environmental pollution.
At present, the common Biodegradable mailing bags on the market mainly include starch-based degradable plastic bags, polylactic acid degradable plastic bags, PBS degradable plastic bags, etc. Although these degradable plastic bags are different in degradability, they all have good degradability and can effectively reduce environmental pollution. It should be noted that although degradable plastic bags have degradable properties, they also need to be decomposed under the correct conditions. If these bags are discarded or dumped randomly, they may stay in conditions that are not conducive to decomposition for a long time and still cause pollution to the environment. Therefore, proper disposal and recycling of biodegradable plastic bags is also very important. What are the classifications of Biodegradable Polymailers? 1. Photodegradable plastic bags, in which a photosensitizer is added to the plastic to gradually decompose the plastic under sunlight. It belongs to an earlier generation of degradable plastics, and its disadvantage is that the degradation time is difficult to predict due to sunlight and climate changes, so the degradation time cannot be controlled. 2. Biodegradable plastic bags can be completely decomposed into plastics of low molecular weight compounds under the action of microorganisms. It is characterized by convenient storage and transportation, as long as it is kept dry, it does not need to be protected from light, and has a wide range of applications. It can be used not only in agricultural mulch and packaging bags, but also in the field of medicine. With the development of modern biotechnology, more and more attention has been paid to biodegradable plastics, which have become a new generation of research and development hotspots. 3. Photo/biodegradable plastic bags, a type of plastic that combines photodegradation and microorganisms, it has the characteristics of photodegradation and microbial degradation of plastics. 4. Water-degradable plastic bags, adding water-absorbing substances to the plastic, can be dissolved in water after use. They are mainly used in medical and sanitary appliances (such as medical gloves), which are convenient for destruction and disinfection. Now biodegradable plastic bags are recommended by most experts and enterprises, becoming the next outlet of the packaging industry.
