Aluminum bag is a high-grade printing and packaging material, and it has the advantages of good insulation, airtight body and water vapor, and is not easy to be attacked by bacteria and insects. Mainly used for food-grade packaging.
Aluminum bag is one of the food grade packaging materials, which can be used to guarantee various meat products, such as beef, lamb, chicken legs, duck wings, milk powder and other meat products. Perhaps your question is coming, can the aluminum pouch heated?
The more common ones are beef, lamb, and milk packed in aluminum foil bags. In fact, after our multi-layer compound, they can be heated. Its high temperature resistance can reach 135 ℃. Can be steamed or boiled. There is no need to worry about the problem of bag explosion. Do you want to know that aluminum foil bags are poisonous?
The aluminum foil bag is actually not a separate aluminum foil. We call it the aluminum foil bag because an aluminum foil film is added in the middle of the bag. In fact, the inner layer and the outer layer are made of plastic. The inner layer material generally uses nylon or polyethylene or CPP. They are all internationally recognized safe materials that can directly contact food. Therefore, you can rest assured that they are not poisonous. ,
Aluminium foil, also used as aluminum foil or tin foil, is a thin sheet with a thickness of 0.1mm or less processed by an aluminum foil rolling machine. It is mainly used for cooking in the kitchen, holding food, or for making something that can be easily cleaned. Of materials. Thousands of tons of aluminum foil are used around the world to protect and package food, cosmetics and chemicals. But we use the type and aluminum foil bag made of plastic composite, instead of single-layer aluminum foil paper. How high temperature can aluminum foil bags withstand?
The maximum temperature that the aluminum foil bag can withstand depends on the contents of the bag and the inner layer material. The general aluminum foil can withstand 135℃. So under normal circumstances, there is no problem in heating general food or milk.
Then we look at the precautions for heating aluminum foil bags
The surface cleanliness of the aluminum foil should be high, without oil stains and dust, and the surface tension should be high, which should reach more than 72mN/m. A simple method is to use distilled water to test, the distilled water should be fully wetted on the aluminum foil surface. If the oil stain on the surface of the aluminum foil is serious, it will affect the composite fastness of the aluminum foil and other materials, especially after the packaging bag is cooked at high temperature, delamination and peeling will occur.

1. The surface cleanliness of the aluminum foil should be high, without oil stains and dust, and the surface tension should be high, which should reach more than 72mN/m.

If the oil stain on the surface of the aluminum foil is serious, it will affect the composite fastness of the aluminum foil and other materials, especially after the packaging bag is cooked at high temperature, delamination and peeling will occur.
2. The number of pinholes of aluminum foil should be less. Aluminum foil should be the best barrier material, but if it has pinholes, its barrier properties will be greatly reduced, gas and light will quickly penetrate directly, and the contents will soon deteriorate. In general, the thicker the aluminum foil, the fewer the number of pinholes. For example, the thickness of a 7μm aluminum foil should be less than 200 holes per square meter: 9μm thick aluminum foil, the number of pinholes should be less than 100 holes Square meters. No matter how thick the aluminum foil is, the diameter of the pinhole should not be greater than 20 μm.
3. The aluminum foil bag is soft in texture, and has a good effect of moisture resistance, heat insulation and light protection. It can be kept at room temperature for more than 6 months after cooking at high temperature or killing the game. Generally, we require the cooking temperature of the aluminum foil bag to be 135 degrees Celsius, and cook for 30 minutes.
