Aluminum foil is produced by rolling aluminum slabs cast from molten aluminum in a rolling mill to the desired thickness less than 0.2 mm . It provides a complete barrier to light,oxygen, moisture and bacteria. For this reason, foil is used extensively in food packaging and pharmaceutical packaging. It is also used to make aseptic packaging that enables storage of perishable goods without refrigeration.
Aluminium Foil’s Amazing Properties:
Cost effective
Barrier to moisture, oxygen and other gases, odours, light, fats and grease
Excellent corrosion resistance
Non-toxic; inert to most foods, drugs and cosmetics
Imparts no detectable taste or odour to foodstuffs
Hygienic: foil is sterilized during annealing and does not harbour or promote bacterial growth
Non absorptive
Withstands a wide range of temperatures from deep freeze to the oven
Excellent thermal properties
Excellent heat conductivity and heat dissipation
Good electrical conductivity
High surface reflectivity
Good burst and tear strength yet lightweight and durable
Excellent formability with dead fold properties
High decorative appeal, excellent surface for printing, coating and laminating
Compatible with other laminating material
Recyclable
