Products application

Biodegradable Fresh Bag Modifier
One of the most significant applications of this biodegradable modifier is in the production of biodegradable fresh bags. These bags can be used to store food, vegetables, and other perishable items, reducing the need for plastic bags that often find their way into landfills and oceans. With the Biodegradable Fresh Bag Modifier, food can be kept fresh for longer, without harming the environment.
We can also provide other biodegradable materials suitable for the manufacture of plastic shopping bags, garbage bags, agricultural mulch, disposable tableware and so on.
