Aluminium foil is a very thin aluminium sheet with a gauge below 200 µm, down to 4 µm. It provides a complete barrier to light, gas, moisture and bacteria. As the thickness of aluminium foil decreases, the number of pinholes in the aluminium foil characteristically increases.

Aluminium foil is typically less than 150 µm in thickness. Foils are available in gauges as low as 6.3 µm. Heavier foil gauges (> 17 µm) provide an absolute barrier to gases and liquids. A typical water vapour transmission rate (WVTR) for 9 µm foil is 0.3 g/m 2 per 24 hours at 38 °C and 90% RH.

Aluminum foil has long been used as a barrier layer in flexible packaging. The production of aluminum foil begins with a series of cold roll steps where the thickness of an aluminum ingot is reduced in half with each step. In the final step below 60 μm, the foil is doubled over and sprayed with oil (for release).

QuotationWe are moving into a low carbon economy. New business models, IT innovation, decentralized governance, and energy efficiency are some of the key words that are re-defining our societies. Aluminium is playing a fundamental role to drive this transformation. Aluminium has a broad range of unique properties that contributes to build a new society based on low carbon products, lighter cars, energy efficient-buildings and recycling.
Today, aluminium is the second most widely used metal in the world. This is because aluminium has a unique combination of attractive properties and effects that can be summarized as follows:
※ Low weight
※ High strength
※ Superior malleability
※ Easy machining
※ Excellent corrosion resistance
※ Easy to mill, drill, cut, punch, bend, weld, bond, tape.
Corrosion free and durable: Aluminium develops a natural oxide layer, protecting it against corrosion and making it virtually maintenance free. This makes aluminium the ideal material for packaging, building and vehicles and transport.
Light yet strong: Despite its relatively low weight, aluminium has a remarkable strength to weight ratio. As an alloy, aluminium offers similar performance to advanced steels and titanium.
Energy saving: Aluminium’s unique properties allow for significant energy savings in many applications; for example in vehicles and buildings. In addition, recycled aluminium is highly energy efficient, using only 5% of the energy of primary production.
High versatility: Aluminium is not only light; it has a low melting point and is highly ductile. This makes it easy to work with, shape and join adding to its versatility.
Total barrier: Aluminium can be rolled extremely thinly – less than 100th of a millimetre – while remaining completely impermeable to light, odour and contamination. This makes it the ideal material for packing food, pharmaceuticals and other sensitive products.
