However, the customer group is most concerned about the safety of three-dimensional packaging bags, so the sealing of vertical bags became a very serious problem.

In the market, the sealing of flexible plastic bags such as three dimensional bags is generally presented in the following forms: zipper seal, thermostatic heat seal.

Zipper seal:

A vertical zipper bag specially designed for the food industry can be used to package cereal, pasta, confectionery, dried fruit and other products.
