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.

Soft aluminum foil and metal packaging are two common packaging materials, they have certain differences in material, structure, use and so on. Soft aluminum foil is a form of packaging that processes aluminum foil materials into flexible packaging bags with a specific process, while metal packaging usually refers to packaging containers such as hard metal cans or boxes.

First of all, in terms of material, the soft aluminum foil foil as the main material, through printing, laminating, composite and other processes made of flexible packaging bags, with light weight, moisture-proof, fresh-keeping and other advantages; The metal packaging is usually made of steel, iron, aluminum and other metal materials, the surface is treated or coated, with strong pressure resistance and oxidation resistance.

Secondly, in terms of structure, the common structure of soft foil includes aluminum foil/plastic composite material or aluminum foil/paper composite material, which has good sealing and barrier property, and is suitable for food, medicine and other fields; Metal packaging is usually a tank or box made of metal processing, and it may be necessary to add anti-corrosion layers or gaskets inside.

In addition, in terms of use, soft aluminum foil is mainly used in the packaging of food, beverage, medicine, cosmetics and other fields, and has been widely used in today's life; Metal packaging is more used in canned food, liquid beverages, chemicals and other fields, can provide better protection and preservation effect.

In summary, there are certain differences between soft aluminum foil and metal packaging in terms of material, structure, use and so on. Soft aluminum foil is favored by consumers for its characteristics of lightweight, soft, moisture-proof, fresh-keeping, etc., while metal packaging has unique advantages in specific fields because of its characteristics of pressure resistance, oxidation resistance, corrosion resistance, etc. With the continuous progress of packaging technology and changes in market demand, soft foil and metal packaging will continue to play their respective roles in the future, providing more options for the protection and promotion of products.
