Biomass Degradable 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 if 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 bag: The biochemical process in which the organic matter in the plastic bag is completely or partially converted into water, carbon dioxide/methane, energy and new biomass under the action of microorganisms.

Biodegradable Compostable Bag

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.

Biodegradable or compostable plastic bags are converted into water and carbon dioxide due to biodegradation, and disappear from the environment, achieving a true environmental protection effect.

Photodegradation: Plastics that are degraded by natural light can only be partially or completely damaged.

Thermal Oxygen Degradation: Plastics that are degraded by heat or oxidation can only be partially or completely damaged by corrosion.

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 materials. The commonly used biodegradable or compostable materials are PLA and PBAT. Biodegradable Bags are in 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.
