The advantages of biodegradable plastics are.
1、Reducing carbon emission
Compared with ordinary plastic, one of the main advantages of using biodegradable plastic to make degradable plastic bags is the reduction of carbon emissions generated during the manufacturing process and the least amount of carbon emissions generated during the composting process.
2、Less energy consumption
Although it seems that the cost of investing in biodegradable plastic products is slightly higher at the moment, in the long run, ordinary plastics require reprocessing of fossil fuels to make polymers, while biodegradable plastics require less energy requirements, thus enabling less pollution and environmental impact.
3、Plastic packaging product solutions
The products made of biodegradable plastics, especially in the field of packaging, can replace most of the ordinary plastic products, and the products are more upscale and more in line with the general trend of environmental protection.
Then the disadvantages of biodegradable plastics are.
1, biodegradable plastic needs certain conditions to decompose, which means that biodegradable plastic mixed with other waste to the landfill, its decomposition time may be extended.
2, biodegradable plastic products have a shelf life, after the shelf life physical properties will be degraded. For example, the shelf life of the biodegradable bags produced by Wuxi Pure Yu Environmental Protection is 1 year, more than 1 year, there is a possibility of yellowing color, side seal solidity decline, easy to tear, etc..
3, biodegradable plastic products are stored under certain conditions, it is recommended to store in a dry, sealed, cool place; avoid humidity, high temperature, direct sunlight and ultraviolet radiation, otherwise the bag will have deterioration, accelerated degradation and other phenomena.
Therefore, although there are shortcomings of biodegradable plastic, but in peoples awareness of environmental safety, the advantages of biodegradable plastic completely overshadow the disadvantages, compared with ordinary plastic products, making it a better choice.
