When a product requires multi-layered packaging, manufacturers normally use foil pouches. They are used as the innermost layers of packaging. It’s very important for foil pouches to be of top quality and extremely hygienic since they are in direct contact with the packaged product. Generally, foil pouches are made out of aluminum and protect the product from extreme temperatures. Additionally, foil pouches maintain a low rate of moisture vapor transmission.  

Usually foil pouches have 3-4 layers. The more the number of layers, the better the pouch quality is considered to be. Each additional layer adds to the strength of the pouch. It’s worth a mention here that foil pouches are different than metalized bags.

Foil pouches are extensively used for packaging of cereals. They are so designed that cereals retain their freshness for long periods. With other forms of packaging, cereals might get pest infested. Along with the safety against infestation, these pouches offer a sound storage option. They do not occupy much space and are easily portable.

These flexible pouches are also widely used as packaging for tea and coffee. They ensure the beverages stay fresh and retain their aroma. Foil pouch packaging is used in the non-food arena as well. Since they are hygienic and safe, they are often used for packing surgical instruments and medicines.
