Biodegradable packaging film

Biodegradable packaging film refers to a class of plastic films that can be broken down into harmless substances such as water and carbon dioxide under natural conditions by the action of microorganisms (e.g., bacteria, fungi). These materials were originally designed to reduce the long-term environmental pollution problems caused by traditional plastic products, especially problems such as marine litter. They are usually made of natural polymers or synthetic polymers and are able to decompose rapidly under certain conditions.

Features

1. Environmentally friendly: the most significant feature is its good biodegradability, which can be digested and absorbed by microorganisms in nature after use, and will not cause environmental pollution.
2. Safety: It has no negative impact on human health and can be used for packaging of food contact products.
3. Functionality: In addition to the basic physical and chemical properties of ordinary plastic film, it can also be adjusted according to the needs of air permeability, waterproof and other functional characteristics.
4. Adaptability: It is suitable for a variety of processing methods, including traditional plastic molding processes such as blow molding and injection molding.
5. Cost-effective: although initial production costs may be higher than traditional plastics, in the long run they are more economical overall due to reduced waste disposal costs and potential environmental remediation costs.

Applications

1. food industry: used in the field of fruit and vegetable preservation bags, snack packaging, disposable tableware, etc., both to ensure food safety and reduce plastic waste.
2. Medicine and health care: as a pharmaceutical packaging material, to ensure the effectiveness and safety of drugs.
3. Agricultural cover: made into mulch or greenhouse cover material, help to improve crop yield and reduce soil pollution.
4. Daily necessities packaging: such as personal care products, cosmetics and other small items of packaging, beautiful and practical and easy to recycle.
5. Express logistics: develop fast-degradable express bags specifically for e-commerce to alleviate the increasingly serious problem of express waste.
