Currently, supermarket advertising bags on the market each have their own characteristics—but have you ever wondered what materials they are made of?

Ordinary supermarket advertising bags are mainly made of polyolefins as the primary raw material, combined with other additives. The polyolefins used are primarily PE (polyethylene), also known as soft plastic. However, most enterprises add approximately 30% calcium carbonate to produce corresponding plastic supermarket advertising bags. As a result, these bags do not emit toxic gases when incinerated in landfills.

There are three main types of plastic supermarket advertising bags:

1. Ordinary Plastic Supermarket Advertising Bags: Made mainly of polyolefins and fillers, these bags are not degradable but can be recycled and reused.
2. Starch-Based Plastic Supermarket Advertising Bags: Primarily crafted from modified starch, with a small amount of other degradable materials added to enhance performance. A key advantage is that these bags are biodegradable.
3. Degradable Plastic Supermarket Advertising Bags: Produced using degradable materials, these bags offer complete degradability and are non-polluting to the environment.
