Will excessive heat and humidity accelerate the degradation of biodegradable film bags?

Yes, excessive heat and humidity can indeed accelerate the degradation process of biodegradable film bags.
Firstly, temperature is an important factor affecting the degradation rate of biodegradable film bags. Generally speaking, the higher the temperature, the faster the degradation rate of the film bag. This is because high temperature is conducive to the activity of microorganisms, which can accelerate the decomposition of polymers in film bags through the action of enzymes and proteins.
Secondly, humidity is also a key factor affecting the degradation rate. High humidity is beneficial for the reproduction of microorganisms, thereby promoting the degradation rate of film bags. In addition, humidity may also cause the material to absorb water and expand, further accelerating the decomposition process.
However, it should be noted that although high temperature and humidity can help accelerate degradation, excessive temperature or humidity may have adverse effects on the stability of certain biodegradable materials. Therefore, when handling and storing biodegradable film bags, appropriate temperature and humidity conditions should be controlled to ensure their effective degradation and environmental performance.
