What is a biodegradable packaging bag?spout pouch serves Solution

A biodegradable plastic bag is a type of plastic bag that can completely degrade water, carbon dioxide, and other small molecules. The main source of this biodegradable material is polylactic acid (PLA) extracted from corn and cassava. Planet (PLA) is a new type of biological base material and a renewable biodegradable material. After fermenting glucose and producing high-purity lactic acid from certain strains, a certain molecular weight polylactic acid is synthesized through chemical synthesis methods, and then glucose is obtained through saccharification. This product has good biodegradability and can be fully degraded by natural microorganisms after use, producing carbon dioxide and water. It will not cause pollution to the environment after use. It is very beneficial for environmental protection and is considered an environmentally friendly material.

At present, the main biological material for biodegradable plastic bags is PLA+PBAT, which can be completely decomposed into water and carbon dioxide within 3-6 months under composting conditions (60-70 degrees Celsius). No pollution to the environment. Why add PBAT? PBAT is a copolymer of adipic acid, 1,4-butanediol, and terephthalic acid, which is a fully biodegradable chemically synthesized aliphatic and aromatic polymer. PBAT has excellent flexibility and can be used for film extrusion, blow molding, extrusion coating, and other molding processes. The blending of PLA and PBAT aims to improve the toughness, biodegradability, and formability of PLA.

2. Where are the manufacturers of biodegradable bags with good reputation?

In the field of biodegradable plastic bags, mature production lines have been formed for the production of biodegradable raw materials such as blow molding machines, printing machines, bag cutting machines, waste recycling granulators, and various fully biodegradable plastic bags. The products cover vest bags, garbage bags, hand held bags, clothing bags, hardware bags, cosmetics bags, food bags, card head bags, kraft paper/PLA composite bags, etc., with stable quality, high production efficiency, exquisite printing, moisture-proof, puncture proof, non-toxic, good sealing, good stretchability, good texture, and environmental protection.

3. What products can biodegradable packaging bags be used for?

Biodegradable plastic bags are widely used in industries such as shirts, knitwear, clothing, textiles, food, hardware, electronics, cosmetics, etc. Biodegradable plastic bags have many sealing designs, such as bone bonding, zippers, tape, etc., and biodegradable plastic bags are compounded with paper to fold the bottom organs. Nowadays, biodegradable plastic bags are entering various industries and styles are also diverse; In the future, biodegradable plastic bags will become an absolute product in the packaging industry.
