In recent years, due to the implementation of environmental protection policies, people have begun to pay attention to the use of environmentally friendly products, such as biodegradable shopping bags, PLA degradable disposable straws, etc. This also includes the use of fully biodegradable ziplock bags (hereinafter referred to as fully biodegradable ziplock bags).

Are fully biodegradable ziplock bags and plastic ziplock bags the same?

Answer: They are 2 completely different bags.

Plastic ziplock bags are generally made of polyethylene PE as raw material and processed through film blowing, printing, cutting and other steps. After use, plastic ziplock bags cannot degrade by themselves in landfills. They can exist in the environment for decades or even centuries, becoming "white garbage", thereby polluting the environment and affecting people's lives and health. Degradable ziplock bags are generally made of polylactic acid PLA and polyadipic acid PBAT. Polylactic acid (PLA) is a new biodegradable material made from renewable plant resources such as corn. Degradable ziplock bags made of polylactic acid (PLA) and other materials have good biodegradability properties. They are completely decomposed by natural microorganisms after use and degrade into carbon dioxide and water by themselves within 180 days. They do not pollute the environment and are very helpful for environmental protection.

Because of the degradation characteristics of fully degradable ziplock bags, let’s talk about its storage issues. Avoid direct sunlight and pay attention to maintaining dry and ventilated storage conditions in the warehouse. After the finished fully degradable ziplock bag is stored for 12 months, the strength and softness of the fully degradable ziplock bag will decrease to a certain extent, and the original normal use function will be lost. Therefore, the production plan is generally based on the usage of 2-3 units, so as to maintain a good use experience.
