Straw is a renewable biological resource with a crude fiber content of 30% -40%, and contains lignin, etc, added to plastics can significantly improve the tensile strength and bending strength of plastic materials. Downstream products can be produced by traditional plastic processing methods such as injection molding, blow molding, suction molding, and extrusion.
There are currently three types of so-called environmentally friendly plastic bags: degradable plastic bags, biodegradable plastic bags, and compostable plastic bags. Everyone thinks that degradability is biodegradation. In fact, it can only be decomposed into carbon dioxide and water to protect the environment.
Biodegradable Bag: The polymers in the plastic bags cause local or complete damage due to ultraviolet radiation, oxidative corrosion, and biological corrosion, which means changes in performance, discoloration, cracking, and fragmentation.
Compostable Bag: The organic matter in the plastic bag is completely or partially converted into water, carbon dioxide / methane, energy and the biochemical process of new biomass under the action of microorganisms.
Composting bags: Plastic bags can be biodegraded under the special conditions of high temperature soil, and usually need to be degraded in industrial composting.
The plastic bags are biodegradable or compostable, they are converted into water and carbon dioxide due to biodegradation, and they disappear from the environment to achieve 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 due to corrosion.
When purchasing biodegradable or compostable plastic bags, you need to check whether the bags are issued with the nationally prescribed plastic bag logo, and judge the production raw materials according to the logo. It can be degraded into water and carbon dioxide in 180 days under the conditions of nature and soil or industrial compost. It belongs to the organic cycle and is harmless to the human body and the natural environment.
Our Biodegradable Bag Manufacturers are committed to developing biodegradable plastics of various environmentally friendly materials that meet the needs of various markets. They are mainly used in biodegradable bags, environmentally friendly packaging bags, injection molded products, and hard packaging!
