Biodegradable bag

…

Material composition

Mainly made of biodegradable polymers, such as polylactic acid (PLA), which comes from renewable resources such as corn starch; Polyadipic acid/polybutylene terephthalate (PBAT); And starch based materials, etc.

Degradation principle

In specific natural environments such as soil, composting environments, water bodies, etc., the polymer molecular chains of bags are gradually decomposed into small molecule compounds through the action of microorganisms such as bacteria, fungi, etc., and ultimately converted into carbon dioxide, water, biomass, etc.

advantage

Environmental friendliness: Compared with traditional plastic bags, under appropriate conditions, it can effectively reduce environmental pollution and reduce the accumulation of plastic waste.

Resource sustainability: Many of its raw materials come from renewable resources, which helps promote the sustainable use of resources.

Usage scenarios

Packaging field: It can be used for food packaging, such as packaging of fruits, vegetables, bread, etc., to reduce the impact of packaging waste on the environment while ensuring food hygiene.

Daily shopping: used as a shopping bag to replace some traditional plastic bags.

limitations

Degradation condition limitations: Although biodegradable, certain environmental conditions are required for effective degradation. For example, in environments with low temperatures or a lack of microorganisms (such as some arid areas or anaerobic environments inside landfills), the degradation rate may be very slow or even difficult to degrade.

Cost issue: Production costs are usually higher than traditional plastic bags, which may result in a lack of competitiveness in terms of price, affecting their market promotion and popularity.
