In the field of food, boiled bags and cooking bags are the first choice for
all kinds of cooked foods. So what is the difference between boiled bags and
cooking bags? Packaging analyzes the differences between the two from the
aspects of materials, sterilization methods, characteristics and applicable
food.
Material difference
The boiled bags and cooking bags are made of composite. The common
materials for boiled bags include NY/CPE, NY/CPP, PET/CPE, PET/CPP, PET/PET/CPP,
and so on. The material of the boiled packaging bag must have good chemical
stability, and should not have any chemical reactions with the food food. In
addition, the thermal seal should choose the material with higher thermal seal
strength, and the crystals and impurities that cannot affect the use can be
ensured to ensure water to ensure water to ensure water. The bags are not
damaged during the cooking process.
The materials for cooking packaging are usually NY/CPP, PET/CPP, NY/NY/CPP,
PET/PET/CPP, PET/AL/CPP, PET/AL/NY/CPP, etc., which have a representative
cooking bag structure The outer layer is a polyester film, which is used for
enhanced; the middle layer is aluminum foil, used as light -proof, humidifying
and leak -proof gas;
Sterilization
The sterilization method of boiled bags is divided into low -temperature
sterilization and Basal sterilization. Low -temperature sterilization is about
30 minutes of sterilization in a 100 -degree environment; Basal sterilization is
about 30 minutes of sterilization in 85 degrees. The characteristics of heat are
handled with appropriate temperature or appropriate insulation time to kill
them.
The sterilization method of cooking bags is general sterilization, high
temperature sterilization and high temperature resistance. General
sterilization, the cooking temperature is 100 ~ 200 ° C, sterilized for 30
minutes; high temperature type, the cooking temperature is 121 degrees Celsius,
sterilized for 45 minutes; the high temperature resistance, the cooking
temperature is 135 degrees Celsius, and sterilized for 15 minutes.
Features and use
The boiled bag can withstand no more than 105 degrees Celsius temperature
sterilization treatment. The oil resistance and thermal sealing strength are
good, it is easy to print, and the impact resistance is high. Suitable for foods
such as sausages, rice dumplings.
The cooking bag has the characteristics of moisture -proof, shielding,
temperature resistance, and incense. It is suitable for cooked foods, such as
meat, ham, etc.
