The country has vigorously developed the environmental protection industry, and the strongest plastic restriction order in history has been promulgated by the country and society's determination to environmental protection. In this context, biodegradable plastic bags are increasingly welcomed for its degradable characteristics. But it is also because of this characteristic that some people ask questions. Can biodegradable plastic bags have a shelf life? After a long storage time, will the firmness be affected?
At present, the most common and most widely used biodegradable plastic bag is PLA. It is a new type of biodegradable material that uses renewable plant resources (such as corn) starch raw materials. It has good biodegradableness and can be completely degraded by microorganisms in nature after use. It finally generates carbon dioxide and water. It does not pollute the environment. This is very beneficial to protect the environment and is recognized as an environmentally friendly material.
Data show that under the influence of temperature higher than 55 ° C or oxygen and microbial, waste for 6-12 months to degrade carbon dioxide and water. These carbon dioxide and water are reused by plants to generate starch in photosynthesis.
The focus is that the degradation conditions need to be degraded under the action of 55 degrees or oxygen -rich and microorganisms. Therefore, pay attention to the storage conditions, store degradable plastic bags in dry and ventilated places to avoid direct sunlight. Decomposed.
However, because the nature of the biodegradable plastic bag itself, after 6-12 months in the ordinary environment, the strength and flexibility will also degenerate. Therefore, there is still such contradictions in degradable plastic bags. Degradable and long -term storage cannot exist together. Purchasing the degradable plastic bag in appropriate amount is currently a better solution.
