With its light weight, small size, fast thermal conductivity, short sterilization time, and good maintenance, the color and fragrance of the content gradually replaced some iron cans and glass tanks, but due to the many performance of the packaging materials The impact of the process is greater, so there is a potential risk of breaking bags.
Reason one: substrate problem
The cooking bag is heated with the product, which determines that the surface materials of the cooking bag have very good stability after cooking, especially the stability of the size after the cooking is cooled. After the cooler is cooled, the lying layer will cause the phenomenon of breaking bags.
Responses:
The cooking bags are generally used in PET, NY, AL, RCPP and other substrates with better high temperature resistance. Pay attention to the shelf life of various substrate materials. In particular, the shelf life of RCPP should be paid. The performance of the bag plays a core role. If the quality of the RCPP is poor or the shelf life is over, it will be largely crispy when cooled and cooled.
Reason two: The impact of bag making process
The temperature, pressure and speed of the hot knife are the three major elements of the bag -making process. To make a good sealing bag, the three are reasonable. Thermal seal is the result of the common role of heat and force. On the one hand, the sealing surface in the melting state, the large molecules spread, penetrate, and wrap each other to achieve closed sealing; on the other hand The pressure of the knife tool enables the upper and lower layers of film to integrate with each other, and it can maintain a certain strength after cooling.
Responses:
Due to the high requirements of the use environment, the boiled bags generally need a strong heat sealed strength, which requires the combination of the structure and the inner material of the cooking bag to reasonably set the temperature and pressure. The sealing at the junction with the bag body is because of the shrinking of the material, the transfer level will become the focus of moisture and heat offensive. The number of thermal seals is largely affected by the heat sealed strength. The number of horizontal seals and vertical seals can be well guaranteed to ensure that each edge of each seal has a good heat sealed strength when making bags.
