Is Degradable Plastic Bag Equal Is Degradable PlastTo Biodegradable Plastic Bag?

Jan. 18, 2021

With the introduction of the first plastic ban, more and more attention has been paid to the environmental pollution caused by plastic bags. Recently, after a lapse of twelve years, plastic restrictions have come back. 24 provinces across the country have successively issued "plastic restrictions" ". In addition to prohibiting and restricting the use of plastic products, various localities have also proposed to accelerate the promotion of the application of alternative products and models. So what kind of plastic bag can be used instead? Biodegradable plastic bags are a good choice, because the use of biodegradable plastic bags will not only provide us with convenience, but also will not pollute the environment. At present, biodegradable plastic bags are not popular yet. Understand, what kind of bag is a degradable plastic bag? Is degradable plastic bag equal to biodegradable plastic bag? The following Biodegradable Bag Manufacturers will come to give everyone a popular science.

Compostable Plastic Bag

Compostable Plastic Bag

There are currently three so-called environmentally friendly plastic bags: degradable plastic bags, biodegradable plastic bags, and compostable plastic bags. Everyone thinks that biodegradability means biodegradation. In fact, it is not. Only when it can be decomposed into carbon dioxide and water can it protect the environment.

Degradable plastic bag: The polymer in the plastic bag is partially or completely damaged due to ultraviolet radiation, oxidation corrosion, and biological corrosion, which means performance changes, fading, cracking, and fragmentation.

Biodegradable Plastic Bags: The biochemical process in which organic matter in plastic bags is completely or partially converted into water, carbon dioxide/methane, energy and new biomass under the action of microorganisms.

Compostable plastic bags: Plastic bags can be biodegraded under the special conditions of high-temperature soils, and usually require industrial composting to achieve better degradation.

The biodegradable plastic bag can be biodegradable or compostable. It is converted into water and carbon dioxide due to biodegradation, and disappears from the environment, achieving a true environmental protection effect

To buy a biodegradable or Compostable Plastic Bag, you need to check whether the bag is issued with a plastic bag label specified by the country. According to the label, determine the production raw materials. The commonly used biodegradable or compostable raw materials are PLA and PBAT. It can be degraded into water and carbon dioxide in 180 days under the conditions of nature and soil or industrial compost, which belongs to the organic cycle and is harmless to the human body and the natural environment.
