Biodegradable plastic bags bring good to people's lives!
Plastic is an important product that is indispensable in our daily life and industrial production. We usually use waste plastics, and most of them are incinerated, except for a very small amount of recycling. Plastic incineration produces a large amount of harmful gases, which not only causes serious pollution to the atmosphere, but also poses a harm to human health that cannot be underestimated. In order to solve the pollution problem of waste plastics, people have developed a new type of plastic, which is a degradable plastic.
There are two types of degradable plastics: photodegradable plastics and biodegradable plastics. Photodegradable plastics add photosensitizers to plastics to accelerate its aging under the ultraviolet rays of the sun to achieve the effect of decomposing plastics; biodegradable plastics graft the molecules of natural materials such as starch to the macromolecules that make up the plastic. The decomposition of starch by microorganisms in soil and water causes the long molecular chains of plastics to break into molecular chains that are easily decomposed and absorbed by microorganisms.
Degradable plastics not only have the same safety and reliability characteristics as ordinary plastics, but they can also solve various hazards such as non-perishable after being discarded or pollution caused by incineration, and become the development direction of the plastic industry.
Biodegradable plastic bags are environmentally friendly, generally do not cause secondary pollution, and have low cost. It has achieved harmless resource utilization, made the best use of materials, turned waste into treasure, and resource-based products have high value and a broad market.
Biodegradable plastic bags are completely degradable. Biodegradable plastics are articles made from plant straws that are friendly to the human body and the environment. They are different from the three synthetic plastics. After being discarded, they can be decomposed by themselves under the action of the biological environment. It is harmless to people or the environment and belongs to green packaging. Biodegradable plastic bags are a kind of disposable shopping bags that are "degradable and easily degradable". Degradable plastic bags can be divided into two types in terms of raw materials and decomposition factors: one is a plastic bag made of polyethylene plastic as the main ingredient and mixed with biodegradable agents such as starch, also called a biodegradable plastic bag. This kind of plastic bag is decomposed mainly by microorganisms. The other is a plastic bag mainly made of polyethylene plastic, blended with a photodegradant and mineral powder such as calcium carbonate, also called a photodegradable plastic bag. This plastic bag is decomposed under the action of sunlight.
We offer patented full biodegradable film and PVA bag, all products are made by casting equipment, It is different from traditional blow molding products, all blow molding products are non full biodegradable. We can produce pva films and bags in full transparent and various colors. and the PVA film is more smooth than the traditional blow molding products.
We also offer organic material full biodegradable film and bags with patented raw material and production Process.
