What is the difference between vacuum packaging bags and regular plastic bags?

Nowadays, product packaging can be made of various materials, but when it comes to plastic flexible packaging, there can be dozens of different types. Currently, the commonly used flexible packaging in the market is not only the various plastic bags we use in our daily lives, but also the vacuum packaging bags used for products sold in supermarkets and shopping malls. So, what are the differences between vacuum packaging bags and ordinary plastic bags?

2. Different performance

Vacuum packaging bags have good impermeability and high barrier properties. Whether it is oil or moisture, they will not leak out through the packaging bag, while ordinary packaging bags are prone to leakage.

3. Different prices

Due to their different materials, the price of vacuum packaging bags is higher than that of ordinary plastic bags.

4. Different processes

Due to different materials, vacuum packaging bags are generally produced using co extrusion or composite methods, while the production process for ordinary plastic bags is much simpler.
