About Aluminium Foil
Aluminium foil used in food service and
packaging industries is virtually a wide range of alloys made by pure aluminium
mixed with small amounts of other metals, which are added to acquire the
desired performances of various applications or to reduce the thickness yet
retain the strength and durability of aluminium foil. It is a very thin sheet ranging
from 0.006mm to the upper ISO defined limit of 0.2mm.
Even very thin, it provides a complete
barrier to light, oxygen, grease, moisture, odor and
contamination. Once food being wrapped or packed with aluminium foil rolls or
containers, it can be preserved fresh for a long time without deterioration. Aluminium
foil’s superior malleability allows it to be cast into different shapes and
thickness without losing its barrier integrity.
It is sterile and hygienic due
to the high temperature in annealing process. Plain aluminium foil is safe and
corrosion resistant in direct contact with most foodstuffs. It can be lacquered
with different coatings to enhance its corrosion resistance and visual
attraction.
Aluminium foil is the most versatile
material for food processing, for it withstands the extremes of temperatures ranging
from freezing cold to baking hot, and thus it offers a superb one-stop solution
by processing the food directly from freezers to (microwave) ovens to table
serving.
It is 100% recyclable and
environmentally friendly. Both aluminium foil scrap and used aluminium foil
products can be recycled endlessly to make brand new products with minimum loss
of the material’s original properties. Containers made of aluminium foil are
light-weighted but robust enough to hold a large quantity of food. They can be
stacked neatly to save space and cost in transportation.
The metallic gloss in aluminium foil itself can promote the visual appeal of its content. It can be further decorated with embossing, lacquers or prints. It is favored by designers for its compatibility with most of the printing technologies. The customized logos or user instructions can be printed onto its surface for brand promotion or safe utilization.
