‌The main problems that may be encountered during the use of high-temperature cooking retort bags include delamination and bag breakage

Delamination problem ‌

Material problem‌: The material of the high-temperature cooking bag is composed of a multi-layer composite film. If the material quality is not good, especially the bonding between the inner layer and the outer layer is not tight, it is easy to cause delamination problems‌

Manufacturing process problem‌: Improper control of parameters such as temperature and pressure during the manufacturing process may cause delamination. For example, problems such as inappropriate temperature and insufficient pressure will affect the quality of the bag‌

Temperature and pressure problems during cooking‌: During the high-temperature cooking process, if the temperature and pressure exceed the tolerance range of the high-temperature cooking bag, it will also cause delamination‌

Breakage problem ‌Bag design problem‌: If the design is unreasonable, such as the bag is too small and the bottom is not firm enough, it is easy to break the bag during the cooking process‌

Food material problem‌: Some foods with a harder texture (such as nuts, bones) or foods that are easy to produce gas will put pressure on the bag during the cooking process, causing the bag to break‌

Temperature and pressure issues during cooking: If the temperature and pressure during cooking exceed the tolerance of the high-temperature cooking bag, it will also cause the bag to rupture. ‌ 1

Countermeasures ‌ Material selection: Select high-quality, tightly bonded high-temperature resistant materials to ensure that each layer has good adhesion. ‌ 1

Process control: Strictly control the manufacturing process to ensure that parameters such as temperature, pressure, and speed are within the appropriate range. ‌ 1

Design optimization: According to the characteristics of different foods, the shape and size of the high-temperature cooking bag are reasonably designed to enable it to withstand extrusion pressure and temperature changes. ‌

Strengthen testing: Strictly test the products produced to ensure the quality of each batch of products. ‌
