Soft foil

Soft foil

Aluminum foil has a high sealing, very low air permeability, oxygen permeability. Combined with its own metal radiation, plasticity, widely used in life. It is basically divided into: aluminum paper, aluminum plastic, Tetra Pak (seven layers), heat seal, milk cover and so on. Especially in the fields of medicine, high-end food, cosmetics, cigarette cardboard and so on is a very practical basic material.

The thickness selection of soft foil is usually between 0.006mm and 0.2mm, and the different thickness of soft foil has different advantages and characteristics in different applications.

First of all, 0.006mm to 0.01mm thickness of soft aluminum foil is mainly used in food packaging, pharmaceutical packaging and other fields, these thin aluminum foil can effectively protect food and drugs from oxygen, moisture and bacteria, extend the shelf life of products, to ensure the safety and freshness of food and drugs.

Secondly, 0.01mm to 0.1mm thickness of soft aluminum foil can be used for the packaging of electronic products, these thickness of aluminum foil has good electrical conductivity and shielding performance, can effectively prevent static accumulation and electromagnetic interference, protect the stability and reliability of electronic products.

In addition, 0.1mm to 0.2mm thickness of soft aluminum foil is usually used in construction, automotive and other fields of thermal insulation, sound insulation materials, these thicker aluminum foil can effectively resist high temperature, high pressure and external noise, to maintain the indoor environment comfort and quiet.

In general, the thickness of the soft foil depends on the specific application needs, choosing the appropriate thickness can play the functional advantages of the soft foil, improve the performance and quality of the product.
