Why Are Food Cooking Bags Vacuum Bags?

- Jan 15, 2019-

Food cooking bags are packaging bags that can withstand high temperature steaming and cooking. They have good temperature resistance, are not afraid of high temperature, and do not deform or release harmful gases and substances at high temperature.

This is because if there is gas in the bag, when the cooking bag is heated, the gas will expand under the promotion of heat, and then burst the bag, which will destroy the sealing effect and taste of food.

When food cooking bags are pumped into vacuum bags, there is no gas in them. No matter how much the outside temperature is heated, they will not destroy the packaging bags due to the expansion and contraction of heat, thus protecting the quality and taste of food in food cooking bags.
