First explain the retort pouch. The cooking bag vacuum bag is a kind of plastic packaging bag that can be heated. It is mainly made of three-layer composite material. It has the functions of preventing light, moisture, air leakage, temperature resistance, shading, and fragrance. It is a high-temperature cooking vacuum bag.

The third type: high temperature resistant type, the cooking temperature is 135℃, and the sterilization is about 15 minutes

The characteristics of the boiled bag: it can withstand the sterilization treatment at a temperature not higher than 105 ℃, does not delaminate, does not leak the bag, has good oil resistance, has good printability, and prints beautifully. The heat sealing strength is very good, the puncture resistance is good, and the impact resistance is also high.

Boiled bags are sterilized by water, and there are two types of sterilization for boiled bags:

The first type: low-temperature sterilization, sterilization at a temperature of 100 ℃ for about 30 minutes.
