Temper Codes Explained

High Quality Aluminum Foil for Packaging, Cable & Battery

Temper tells you how hard or soft the foil is. It also reveals how much the metal was worked after the final anneal.

TemperDescriptionFeelBest For
O (Soft)Fully annealedVery pliableWrapping food, deep drawing
H14Strain-hardened, quarter hardSlightly stiffMedium-duty packaging
H18Strain-hardened, full hardRigid, springyRigid containers, fins
H22Partially annealed after hardeningSoft with some strengthLidding, semi-rigid trays
H24Similar to H22, slightly harderFirm but formableBottle caps, shallow draws

Soft temper (O) is what you feel in kitchen rolls. Hard temper (H18) holds shape in baking pans.


Thickness Breakdown

Foil thickness is measured in microns (μm) or millimeters (mm). Some buyers still use gauge, but metric is standard in China.

CategoryThickness RangeMicron EquivalentTypical Products
Ultra-light0.006–0.009 mm6–9 μmChocolate wrapping, capacitor film
Light0.010–0.019 mm10–19 μmHousehold rolls, flexible pouches
Standard0.020–0.039 mm20–39 μmContainer lids, insulation layers
Heavy0.040–0.099 mm40–99 μmDeep trays, industrial gaskets
Extra-heavy0.100–0.200 mm100–200 μmRigid pans, structural honeycomb

Anything below 0.2 mm is generally called foil. Above that, the industry shifts to “aluminum sheet.”

Maximum coil weight depends on the mill. Common ranges are 500 kg to 8000 kg per coil. Some large mills handle up to 15 metric tons.


Aluminum Foil Supplier China Quality Checks Before Shipment

Reliable suppliers run multiple tests. Buyers should ask for these reports.

  • Thickness gauge: Laser or micrometer scan across the full width
  • Tensile test: Measures strength and elongation
  • Erichsen cupping: Tests deep-draw capability
  • Pinhole count: Counts light leaks per square meter
  • Surface inspection: Camera systems detect scratches and stains
  • Chemical analysis: Confirms alloy composition
  • Oil residue test: Ensures clean surface for lamination
  • Wettability test: Checks surface energy for coating adhesion

How to Choose the Right Supplier

Not every factory fits every buyer. Consider these points.

  • Experience: How many years in foil production?
  • Equipment: Does the mill have modern cold rolling mills?
  • Certifications: ISO, FDA, SGS, REACH, RoHS?
  • Export history: Do they ship to your country regularly?
  • Sample policy: Will they send free samples for testing?
  • Payment terms: T/T, L/C, or D/P?
  • After-sales support: How do they handle quality claims?

Visit the factory if possible. Video audits are a good second choice.


Frequently Asked Questions

What is the most common alloy for household foil?

Alloy 8011 dominates. It balances cost, softness, and tear resistance. Some premium brands use 1235 for higher purity.

Which temper should I pick for deep-drawn containers?

Choose O temper (soft annealed). It stretches without tearing. H22 is acceptable for shallow draws.

Can I order foil thinner than 6 microns?

Yes, but only from specialized mills. Capacitor foil can reach 4–5 microns. Battery foil is now produced at 8 microns. Thinner foil costs more and has higher pinhole risk.

Is Chinese aluminum foil food-safe?

Reputable mills use food-grade alloys and annealing processes. Look for FDA, EU 10/2011, or GB 4806 compliance certificates. Always verify with lab tests if unsure.

What is the difference between 8011 and 8079?

Both are 8xxx series. 8079 has slightly different iron and silicon levels. It offers better barrier properties in thin gauges. Flexible packaging makers prefer 8079. Household product makers prefer 8011.

How do I prevent foil from cracking during stamping?

Use soft temper (O). Keep the foil warm. Apply proper lubrication. Check die clearance. Choose an alloy with good elongation, such as 8011 or 3003.

Can foil be recycled?

Yes. Aluminum recycles indefinitely. Clean household foil goes into standard recycling streams. Laminated or heavily soiled foil may need special handling.

What surface treatments improve printing adhesion?

Corona treatment or chemical priming raises surface energy. Matte finishes also accept ink better than bright finishes. Ask your supplier for dyne level test reports.

Do you supply colored foil?

Yes. Anodized colors and painted coatings are both available. Gold, red, blue, and black are popular for food service and gift packaging. Custom Pantone matching is possible at volume.

What is the typical shelf life of aluminum foil?

Pure foil does not expire. It does not rust or degrade. However, printed or laminated products may have a 12–24 month shelf life due to adhesives or inks. Store in dry conditions away from acids.
