What is the typical lifespan of biodegradable grass film?

The service life of biodegradable grass film is affected by various factors, usually ranging from a few months to a year, as follows:

-Material composition: A biodegradable grass film mainly composed of polylactic acid (PLA), polybutylene adipate terephthalate (PBAT), etc. It can degrade quickly in natural environments and may have a relatively short service life, generally 6-10 months. And some grass films made from biodegradable materials with special additives or modified technology may have their service life extended to 8-12 months or even longer. For example, adding an appropriate amount of nanoclay to PBAT can improve the mechanical properties and water resistance of the film, thereby extending its service life.

-Environmental factors such as temperature, humidity, and light have a significant impact on the service life of biodegradable grass film. In high temperature and high humidity environments, the degradation rate of biodegradable grass film will accelerate, and its service life may be shortened to 6-8 months. On the contrary, in a low-temperature and dry environment, its degradation rate will slow down, and its service life may be extended to 10-12 months. In addition, long-term exposure to sunlight can accelerate the aging and degradation of the film, and if there are shading measures in the usage environment, the service life of the film will be relatively longer.

-Usage: If the biodegradable grass film is subjected to frequent stretching, friction, or contact with sharp objects during use, it may be damaged, thereby affecting its service life. The correct usage method, such as avoiding excessive stretching, preventing scratches, etc., can bring the service life of the film to a normal level; On the contrary, improper use may cause serious damage to the membrane within a few months and render it unusable.

-Production process: Degradable grass film with advanced production technology and strict quality control, uniform molecular structure, stable performance, and relatively long service life. For example, films produced using advanced blow molding technology have uniform thickness, good mechanical properties, and can better resist damage from external factors, with a service life of up to 8-12 months. Improper process control during production can lead to defects in the film, such as uneven thickness and bubbles, which may make it more susceptible to damage during use and shorten its lifespan to 6-10 months.
