When products need to be moisture-proof and waterproof, aluminum foil bags are usually used.
In fact, aluminum foil can also be made into high-temperature aluminum foil cooking bags, so why can aluminum foil withstand high-temperature cooking? Is cooking on aluminum foil safe?
The Advantage of Cooking with Aluminum Foil
First, the aluminum foil bag has good sealing performance and good barrier properties. The number of pinholes in aluminum foil is small. However, if it has pinholes, its barrier properties will be greatly reduced, gas and light will quickly and directly penetrate, and the product will deteriorate and be damaged.
Second, the aluminum foil bag is food-safe, with high cleanliness, no oil stains and dust, and strong external tension. A simple method is that distilled water should be fully moisturized on the surface of the aluminum foil bag. If the surface oil of aluminum foil is severe, it will affect the composite fastness of aluminum foil and other materials, especially after the packaging bag is cooked at high temperature, delamination and peeling will occur.
The aluminum foil has a soft texture and is easy to crack. It must have good resistance. The aluminum foil should be stored in a dry state and should not be left for too long. It should be used as soon as possible to avoid aluminum foil absorbing oxidation.
Aluminum foil is a metal. Soft aluminum foil is used in cooking packaging bags. It has excellent moisture resistance, gas resistance and light resistance. At the same time, it is completely impervious to moisture, air, and light. Extremely high heat resistance and oil resistance, aluminum foil material is a necessary material for high temperature cooking bags.
The Material of Cooking with Aluminum Foil
The aluminum foil used to make the cooking bag is mostly composed of three layers of materials. The typical cooking bag structure is: the outer layer is a polyester film for reinforcement; the middle layer is aluminum foil for light, moisture and air leakage protection; the inner layer Polyolefin film (such as polypropylene film) for heat sealing and food contact.
As a powerful aluminum foil manufacuturer, we have many years of experience in the production of cooking aluminum foil, which are exported to all parts of the world.
