Aluminum foil for induction is a special aluminium foil material with the function of electromagnetic induction heating. It is commonly used to seal the lids of bottles, jars or other containers for sterile, airtight packaging.
In addition, aluminium foil for sensing also has the advantages of easy operation, high efficiency and environmental protection.
Based on the principle of induction heating. When placed in an induction heating device, induction foil absorbs energy from a high-frequency electromagnetic field and converts it into heat, which heats up rapidly. When sealing the container, the aluminum foil for induction can be tightly combined with the mouth of the container through heat sealing and pressure, thus forming a complete seal, avoiding the entry of external air and bacteria.

1 series (pure aluminum), 3 series (aluminium alloy with high Mn content), 8 series (aluminum alloy containing iron, silicon, tin and other elements), etc.
Generally speaking, aluminum alloys containing elements such as iron and silicon can improve the induction heating effect of aluminum foil, so that sealed packaging can be achieved faster. However, too high iron content may affect the flexibility and ductility of aluminium foil, so a balance needs to be considered when selecting an aluminium alloy.
It is widely used in the fields of food, medicine, cosmetics, etc., because it can provide sterile airtight packaging, thereby extending the shelf life and stability of the product.
