Aluminum Foil

Aluminum foil is solid rolled aluminum at foil gauge, ordered by alloy, temper, thickness, width, reel geometry, surface, pinhole and converting requirements; it must not be confused with metallized polymer film.

Specifications and dimensions

Thickness in micrometres, width and reel length or mass with applicable tolerances
Core inside diameter, maximum outside diameter, winding direction and splice allowance
One-side bright or two-side matte presentation, wetting, surface energy, pinhole and cleanliness controls

Standards and supply condition

ASTM B479 for annealed aluminum and aluminum-alloy foil for flexible barrier applications where applicable
EN 546 series for aluminum and aluminum-alloy foil products

Manufacturing and processing

Rolling stock is cold rolled through successive reductions and may be double rolled at final gauge.
Annealing, separation, slitting, surface treatment, inspection and clean packing prepare foil for converting.

Typical applications

Moisture and oxygen barrier laminates
Pharmaceutical and food packaging
Cable shielding, insulation and industrial barrier bags

Quality and acceptance controls

Verify the registered alloy and complete temper designation against the certificate and ordered product standard.
Check dimensions, applicable tolerance table, flatness or straightness, surface class, edge and permitted defects.
Control film, interleaving, dryness, contact materials, handling and export packing to prevent staining and damage.

Include in your RFQ

Registered alloy and complete temper designation
Governing product specification and unit system
Dimensions, tolerances, quantity and grain-direction requirement
Surface class, finish, film, edge and processing requirement
Mechanical, conductivity, ultrasonic or other test and certificate requirements
Packing, moisture protection, destination and delivery term

Selection limits

Barrier performance belongs to the complete laminate and seal design, not foil thickness alone.
Metallized film has a deposited metal layer and is not interchangeable with solid rolled foil.
