The difference between high temperature cooking bags and vacuum bags
High temperature retort bags and vacuum bags are very common in the field of food packaging. Retort bags and vacuum bags are used to package various cooked foods and are very convenient to use. Today, BN PACK will tell you the difference between high temperature cooking bags and vacuum bags.
The high temperature cooking bag is a composite plastic film bag that can be heat treated. It has the advantages of both canned containers and boiling water resistant plastic bags. The food can be left intact in the bag, sterilized and heated at high temperature (usually at 120~135°C), and taken out to eat.
The retort pouch has been proven to be an ideal sales packaging container for more than ten years. It is suitable for the packaging of meat and soy products, is convenient, hygienic and practical, and can well maintain the original flavor of the food, which is favored by consumers.

Vacuum bags, also known as personal moisture-proof bags, aluminum foil bags, and aluminum-plastic composite bags, are generally made of PET/AL/CPE or PET/NY/AL/CPE. Among them, PET—good printing effect, NY—low oxygen permeability , AL - strong barrier, opaque, CPE - packaging inner layer. Glue: Water-soluble glue (more hygienic, environmentally friendly, no solvent residue) This product has good anti-static, oxygen barrier, shielding, moisture-proof, shading functions and excellent heat-sealing properties.

Vacuum bags are divided into food vacuum bags, pharmaceutical vacuum bags, electronic vacuum bags, high temperature vacuum bags, low temperature vacuum bags, powder vacuum bags, granular vacuum bags, solid vacuum bags, particle vacuum bags, VIP vacuum bags, STP vacuum bags, 25KG Vacuum bags, anti-virus vacuum bags, vacuum bags for family planning supplies, compressed food vacuum bags, sealed vacuum bags, other vacuum bags.
After the above introduction, do you have a clear understanding of cooking bags and vacuum bags? The material of the cooking bag: NY/PE, NY/AL/RCPP, KNY/PE can be used, suitable for: cooked food, high temperature sterilized food, such as: meat, ham, grilled fish, etc.
There are three types of retort bag sterilization: the first type: general sterilization, the cooking temperature is 100-200 °C, and the sterilization is about 30 minutes; the second type: high temperature type, the cooking temperature is 121 °C, and the sterilization is about 45 minutes; the third type : High temperature resistant type, the cooking temperature is 135℃, and the sterilization is about 15 minutes.
The retort bag is a kind of vacuum bag, which is a vacuum packaging bag that can withstand high temperature. Its material is different from the ordinary vacuum packaging bag, which is made of three-layer materials. Ester film is used for reinforcement; the middle layer is aluminum foil, which is used to prevent light, moisture and air leakage; the inner layer is polyolefin film (such as polypropylene film), which is used for heat sealing and food contact. The materials of ordinary vacuum packaging bags are usually PA/PE or PA/RCPP, PET/PE or PET/PA/PE, which do not have the characteristics of high temperature cooking.
