Some development applications of fully biodegradable packaging bags

2022-05-26 10:11:32

Biodegradable packaging bags refer to a type of plastic that is dissolved by the effects of natural microorganisms such as germs, Aspergillus flavus (bacteria) and algae. The idealized biodegradable plastic is a kind of polymer material with high-quality performance indicators, the waste can be completely dissolved by the microorganisms in the natural environment, and finally inorganically transformed into a component of the carbon cycle system in nature. "Paper" is a typical biodegradable raw material, while "generated plastic" is a typical polymer material. Therefore, biodegradable plastic is a polymer material that combines the characteristics of two raw materials, "paper" and "generated plastic".


Fully biodegradable material

Biodegradable packaging bags should have two levels. On the one hand, they are made of natural stone and can be used repeatedly; (Or the damage to the natural environment is relatively small compared to other raw materials). The general packaging bag is difficult to dissolve after being thrown away in the natural environment, and even a small part of it will form harmful chemicals after being dissolved.


Biodegradable packaging bags are consumables in daily life, and it is necessary for our country to consume a lot of plastic shopping bags every year. Plastic shopping bags provide customers with a fast and convenient way. In addition, due to excessive use and untimely purchase and processing, it also leads to serious energy consumption and air pollution. In particular, thin plastic shopping bags are very easy to damage, and most of them are thrown away casually, becoming the key source of "white garbage". At this stage, more and more countries and regions have already restricted the production, production, sale and application of plastic shopping bags. In order to implement the construction of ecological civilization, the basic construction of a conservation-oriented society and the development of a green and environment-friendly society, strong countermeasures are taken from the root cause, and the company is urged to produce durable and easy-to-buy plastic shopping bags, and correctly guide and motivate the people to use plastic bags reasonably. Shopping bags, promote the development and utilization of resources, maintain ecological and environmental protection, and further promote energy conservation and consumption reduction.


Clothing packaging biodegradable bags are well known to everyone, but if we analyze them in depth, it is very likely that many people only know that they are environmental protection packaging bags. In the case of choosing a distributor of fully dissolving plastic bags, it is very likely that you can only have a rough grasp and look forward to the future. Below, the practical advantages and applications of fully dissolving plastic bags in the technical profession will be explained.


Garment packaging biodegradable bags use tapioca starch as the key material, which can be dissolved into carbon dioxide and water in the geographical environment, reducing the dissolution time of plastics and reasonably reducing air pollution.


1. Environmental protection: The application of fully dissolving plastic bags can greatly reduce the problem that ordinary plastic bags cannot be decomposed and form a flood of white garbage.


2. High-quality characteristics: The fully dissolving plastic bag uses tapioca starch as the key material, its dissolving ability is better than other raw materials, its service life is longer than that of paper bags, and its cost is lower than that of paper bags.


3. Most of the exquisiteness: Fully dissolving plastic bags and general plastics have the same function except for the different ingredients and raw materials. They can be exquisitely packaged and printed, of moderate size, and can pack many commodities.


4. Recycling and reuse: The fully dissolving plastic bag has the characteristics of softness, wear resistance, folding and good layering, and the recycling time is long.


Polylactic acid (PLA) is the key production material for garment packaging biodegradable bags. It is a new type of biodegradable raw material, suitable for various production and processing methods such as extrusion, injection molding, film drawing, spinning, etc. It is fast, so it can also be used in food packaging, clothing packaging, clothing packaging, Chinese fast food lunch boxes, non-proof cloth, industrial production and civilian type cloth, agricultural machinery textiles, 3D printing and other fields.
