Cooking pouches, often referred to as ‘soft cans’, are advanced flexible packaging materials designed for the autoclaving of food products. These packages can withstand high temperature processes and are typically used for ready-to-eat or semi-finished food products that need to be preserved for long periods of time and sold at room temperature. By placing the food in the bag and vacuum sealing, and then high temperature cooking and sterilisation, the shelf life of the food can be effectively extended without the addition of preservatives, and at the same time maintain the original colour, aroma, taste and nutritional value of the food.
Features
- High-temperature resistance: the core feature of the cooking bags is excellent high-temperature resistance, able to withstand a long period of cooking and sterilisation at temperatures from 100°C to 135°C without rupture, deformation or infiltration.
- High Barrier: In order to ensure the freshness and extend the shelf life of the food, the cooking pouches are made of multi-layer composite structure, such as nylon (PA), aluminium foil (AL), polyester (PET), polypropylene (CPP), etc. The combination of these materials can provide excellent barrier to oxygen, water vapour and aroma.
- strong toughness and puncture resistance: in the packaging and transport process, cooking bags need to be able to resist the impact of external forces, to prevent breakage, but also requires that the heating process is not easy to be the sharp parts of the food, such as bone puncture.
- Safe and harmless: all materials must comply with food safety standards, do not contain harmful substances, to ensure that the high temperature treatment will not produce harmful substances migrate into the food.
- Good sealing performance: Ensure that the bags can still maintain good sealing after high temperature treatment to prevent microbial re-contamination.
Applications
- food industry: widely used in meat products (such as ham, sausage), soy products, seafood, soups, vegetables, fruits, ready-to-eat rice, instant noodles, etc., especially suitable for those products with high requirements for freshness.
- medical supplies: certain medical supplies, such as sterilised medical devices, medicines, etc., may also be sterilised and encapsulated using similar steaming packaging technology.
- munitions: army field rations and other food products that require long-term preservation and easy to carry are also often used for steaming packaging bags.
- emergency relief food: disaster emergency food packaging, because of the need for long-term storage and rapid start, so this kind of packaging is very suitable.
