Why aluminium foil works
Foil is a near-perfect barrier: at normal packaging gauges it blocks light, oxygen, moisture and aroma, which is why it protects food and medicines so well. It is also non-toxic, heat resistant, easy to fold and fully recyclable.
Different jobs need different foil. A pharmaceutical blister needs strength and pinhole-free quality; a food container needs stiffness for forming; a household roll needs softness and a clean finish. The alloy and temper are chosen to match.
Foil alloys and their uses
| Alloy | Character | Typical uses |
|---|---|---|
| 1235 | High purity, very soft, excellent for thin gauges | Flexible packaging laminates, cable wrap, tape |
| 8011 | Stronger than 1xxx foil, good formability | Food containers, household foil, bottle closures, pharma |
| 8079 | Excellent ductility and puncture resistance | Pharmaceutical blisters, retort pouches, flexible packaging |
| 1100 / 3003 | Stiffer foil for forming | Semi-rigid containers, fin stock, insulation facings |
Where foil is used

Foil questions
What is the difference between 8011 and 1235 foil?
1235 is a purer, softer alloy ideal for very thin laminating foil. 8011 contains iron and silicon, which make it stronger and better for containers, closures and household rolls.
Which foil is used for pharmaceutical blisters?
8079 and 8011 in soft temper are widely used because they combine barrier properties with good formability.
How should I specify foil?
Give the alloy, temper, thickness in microns, width, core size, roll diameter or weight, and the surface finish required.
