Aluminum Foil Composite Liner Roll Stock - Moisture Barrier Laminate
An aluminium foil composite liner is the barrier layer your product actually depends on. Laminated from foil, film and paper and converted to sit inside the pack, it blocks moisture, oxygen and light so contents stay crisp, aromatic and free-flowing from filling line to end use.
We supply this liner as roll stock, cut sheets or pre-formed inserts, printed or plain, with structure and thickness specified against your product rather than sold off the shelf.
Key Features
- Barrier by specification — foil layer blocks moisture, oxygen and light; structure matched to your shelf-life target
- Supplied to your line — roll stock, cut sheets or pre-formed inserts, slit to your width
- Printed or plain — brand print, handling marks or unprinted barrier stock
- Food-grade material options — Food-contact compliant materials; declarations and certificates provided on request.
- Low minimum order — from 500 pieces, with trial runs often possible.
- Free samples — 3-5 working days

High-barrier foil liner — typical industry reference
The figures below are typical industry reference values for this product category. They are not measured values for your order. The final construction is specified together with your engineers against your pack format, your printing and your packing line.
| Basic construction | Liner base paper + laminating adhesive + aluminium foil + ink |
| Base paper grammage | Typically 50–90 g/m² |
| Aluminium foil thickness | Typically 0.006–0.009 mm |
| Roll width | Typically ~114 mm; other widths slit to your packing line |
| Laminating adhesive | Wet laminating adhesive (acrylic emulsion) or dry laminating adhesive (polyurethane / polyester / acrylic with hardener and thinner) |
| Converting route | Laminating → printing → embossing → slitting |
| Supply format | Rolls, slit to width, wound on a core |
Typical converting route
- Laminating — base paper bonded to aluminium foil, wet or dry; wound into a log and then slit into rolls.
- Printing — brand colour, text and handling marks on the paper side.
- Embossing — pattern embossing, including the gold and red metallized look used on premium packs.
- Slitting — to the width your packing line takes, with controlled tension and a flat roll face.
Measured properties that decide whether it runs
- Moisture and curl control — the base paper takes on and gives off moisture; that is the main cause of curl, winding creases and web breaks.
- Solvent residue — ink and adhesive solvents have to be driven off. The reference test method is headspace gas chromatography–mass spectrometry (HS-GC/MS).
- Ink heat resistance — the printed layer has to survive the heat it meets on the packing line.
- Runnability — slit width, roll face flatness and roll hardness decide how the liner feeds and forms on the machine.
- Width and grammage — width measured with a tool accurate to at least 0.1 mm; grammage weighed on a balance accurate to 0.001 g; D65 brightness read on a whiteness meter.
Standards and compliance
The category's former national standard was withdrawn in 2025 and no direct replacement has been issued. This product is therefore made to our internal control standard together with the applicable food-contact regulations. Food-contact declarations and a solvent-residue (HS-GC/MS) test report are provided on request.
