Aluminium Foil for Beer Labels
Beer label foil is a thin, fully annealed 8011 aluminium foil, typically 9 – 12 µm, that is laminated to paper, printed and embossed to make the shiny neck foils and labels on beer bottles. It must be clean enough to print and lacquer, soft enough to wrap a bottle neck without springing back, and strong enough to survive high-speed labelling, pasteurisation and ice buckets. This guide covers the alloy, properties, quality requirements and how to specify it.

Why beer labels use aluminium foil
Foil neck labels and collars give premium beers their recognisable metallic finish. The foil also helps in practical ways: it conforms closely to the curved neck and crown, resists condensation in coolers, and keeps its appearance through pasteurisation and chilled storage.
Label foil is almost always used as a laminate rather than on its own. The foil is bonded to a wet-strength label paper, then lacquered, printed, embossed and cut into labels on the label converter's lines. The paper gives stiffness for magazine feeding on the labeller and a surface for the glue; the foil provides the look and conformability.
In markets with returnable bottles, labels must also come off cleanly in the hot caustic bottle washer. Paper and adhesive are selected for fast wash-off, and the foil laminate must not break up into fragments that clog the washer. This is one reason brewers specify the whole label construction, not just the foil.
8011 alloy and chemical composition
8011 is an aluminium-iron-silicon alloy. The iron and silicon form fine intermetallic particles that strengthen the foil and refine the grain, so 8011 foil is stronger and stiffer than pure-aluminium foil of the same gauge. That helps the laminate run on the press and labeller. 1235 is used where the lowest pinhole count at very thin gauge matters more than strength.
| Element | 8011 (wt %) | 1235 (wt %) |
|---|---|---|
| Silicon (Si) | 0.50 – 0.9 | Si + Fe ≤ 0.65 |
| Iron (Fe) | 0.6 – 1.0 | (see Si) |
| Copper (Cu) | ≤ 0.10 | ≤ 0.05 |
| Manganese (Mn) | ≤ 0.20 | ≤ 0.05 |
| Magnesium (Mg) | ≤ 0.05 | ≤ 0.05 |
| Chromium (Cr) | ≤ 0.05 | — |
| Zinc (Zn) | ≤ 0.10 | ≤ 0.10 |
| Titanium (Ti) | ≤ 0.08 | ≤ 0.06 |
| Others, each / total | 0.05 / 0.15 | 0.03 / — |
| Aluminium (Al) | Remainder | ≥ 99.35 |
Registered Aluminum Association limits. Label foil can be made from direct-chill cast and hot-rolled stock or from continuously cast strip; both routes are used, with hot-rolled stock usually giving a more uniform surface for decorative work.
Mechanical and surface properties
| Property | Typical for 9 – 12 µm 8011-O label foil | Why it matters |
|---|---|---|
| Tensile strength | About 80 – 100 MPa | Prevents web breaks during lamination and printing |
| Elongation | Around 2 – 4 % at these gauges | Thin foil elongation is low by nature; laminating to paper protects it |
| Surface wettability | Class A brush test (EN 546-4) | Clean, oil-free surface lets lacquer, ink and adhesive wet and bond evenly |
| Pinholes | Low count agreed in the specification | Pinholes show as light specks and can cause lacquer or print defects |
| Surface | One bright and one matt side, or both bright | The bright side normally faces outward for maximum shine |
| Thickness tolerance | Typically within about ±5 – 8 % of nominal | Even gauge keeps lamination and embossing uniform |
Values are typical industry ranges for orientation. Properties are guaranteed by the agreed specification and the mill certificate, which reports actual results for the lot.

From foil coil to finished label
- LaminationFoil is bonded to wet-strength label paper with a water-based or solvent-free adhesive.
- Lacquering and printingA primer or coloured lacquer is applied, followed by gravure, flexo or offset printing; gold and silver effects often come from tinted lacquers on bright foil.
- EmbossingPatterns or brand marks are embossed; O-temper foil takes fine embossing without cracking.
- CuttingSheets or reels are die-cut or guillotine-cut into neck, collar and body labels.
- LabellingLabels are glued onto wet, cold bottles at high speed, wrapping around the neck and crown.
Problems in the field usually trace back to foil surface or gauge: poor wettability causes lacquer to crawl or adhesion to fail, gauge variation shows up as uneven embossing, and coil set or edge waves cause wrinkles at lamination.
Trends: down-gauging, metallised paper and recyclability
Label converters and brewers keep pushing for thinner foil to cut cost and material use. Gauges have moved from around 12 µm towards 10 µm and below, which demands cleaner metal and tighter process control to keep pinholes and breaks in check.
Vacuum-metallised paper competes strongly in neck labels because it is cheaper and washes off and recycles with paper. Foil laminates retain an advantage in appearance, deep embossing and conformability, so many premium brands continue to use them. Whichever is chosen, the label must suit the bottle-washing and recycling route of the market.

Beer label aluminium (aluminum) foil: FAQs
What alloy is used for beer label foil?
8011 in the fully annealed O temper is the standard choice; 1235-O is used where very low pinhole counts at thin gauge are the priority.
How thick is beer label foil?
Typically about 9 – 12 µm before lamination. The trend is toward thinner gauges of around 10 µm and below.
Why is beer label foil laminated to paper?
Paper gives the stiffness needed for label magazines, a surface for the glue and protection for the thin foil, while the foil provides the metallic finish and conformability around the neck.
What does wettability class A mean?
It is the cleanest grade in the EN 546-4 brush test, showing the surface is free of rolling oil so lacquer, ink and adhesive spread and bond evenly.
Do foil labels come off in returnable bottle washers?
They can, if the paper and adhesive are designed for caustic wash-off. Specify the wash-off requirement so the whole label construction is chosen to suit it.
