Fully biodegradable plastic bag materials refer to a type of plastic that is degraded by the action of microorganisms naturally present in nature, such as bacteria, molds (fungi), and algae. Ideally, a fully biodegradable plastic bag is made of a polymer material with excellent performance properties; after disposal, it can be completely decomposed by environmental microorganisms, ultimately becoming mineralized and becoming a component of the carbon cycle in nature. “Paper” is a typical biodegradable material, while “synthetic plastic” is a typical polymer material. Therefore, fully biodegradable plastic bags combine the properties of both “paper” and “synthetic plastic” materials.

Fully biodegradable plastic bag materials, also known as biodegradable plastics, refer to plastics that degrade under the action of naturally occurring microorganisms in natural environments such as soil and /or sand, and/or under specific conditions such as composting, anaerobic digestion, or in aqueous culture, and ultimately completely degrade into carbon dioxide (CO2) or/and methane (CH4), water (H2O), mineral inorganic salts of the contained elements, and new biomass.

Plastics are high molecular weight compounds (macromolecules) polymerized from monomers through addition or condensation reactions with moderate resistance to deformation, between fibers and rubber, composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, pigments and other additives.

The main component of plastics is resin. Resin refers to a high molecular weight compound that has not yet been mixed with various additives. The term resin was originally derived from lipids secreted by plants and animals, such as rosin and shellac. Resins account for approximately 40% to 100% of the total weight of plastics. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are essentially composed of synthetic resins and contain no or few additives, such as organic glass and polystyrene.

Fully biodegradable plastic bags and ordinary plastic bags differ in

1. Different materials

Fully biodegradable plastic bags (also known as environmentally friendly plastic bags) use materials such as PLA, PHAs, PBA, PBS, etc. Non-degradable traditional ordinary plastic bags are made of PE and other plastic materials.

2. Different production standards

Fully biodegradable plastic bags must meet the national standard GB/T21661-2008 and have reached environmental protection standards. Traditional non-degradable ordinary plastic bags do not need to comply with this standard.

  3、 Different decomposition times

Fully biodegradable plastic bags generally decompose within one year, while Olympic environmentally friendly plastic bags can even start to decompose after 72 days. Non-degradable ordinary traditional plastic bags take 200 years to degrade.

Advantages of using fully biodegradable plastic bags

1. Environmental protection: Using fully biodegradable plastic bags can greatly reduce the problem of white pollution caused by the inability of traditional ordinary plastic bags to decompose.

2. Excellent performance: Fully biodegradable plastic bags use starch as the main raw material, have better degradation ability than other materials, longer lifespan than paper bags, and lower cost than paper bags.

3. Exquisite and versatile: Fully biodegradable plastic bags and ordinary plastic bags are the same in function except for the different component materials. They can be beautifully printed, moderately sized, and can package many products.

4. Recycling: Fully biodegradable plastic bags have the characteristics of softness, wear resistance, foldability, and good texture, and have a long recycling period. 。
