Water-based Coated Aluminized Paper

Water-based coated aluminised paper is a coated barrier base paper we supply in rolls or sheets to paper converters and food-packaging producers. A vacuum-metallising and transfer process deposits an extremely thin metallic aluminium layer — typically around 0.02–0.04 μm — onto the paper surface. That layer turns an everyday coated paper into a high-barrier stock that blocks oxygen, moisture vapour, other gases and light, while the sheet keeps the flexibility and converting behaviour a packaging line needs.

As a manufacturer, Bofeng offers this aluminised barrier paper across a range of base papers and metallic finishes. Tell us your converting process and the end use you supply, and we will match the base paper, grammage and gloss to your line.

What is water-based coated aluminised paper

Water-based coated aluminised paper — also referred to as aluminium barrier paper — is a coated paper carrying a metallic aluminium layer applied by vacuum and transfer technology. At roughly 0.02–0.04 μm the metal is a fraction of the thickness of foil lamination, so the paper stays light and flexible, slits and folds cleanly, and takes on a bright metallic surface. The base paper, grammage and gloss level are matched to the final use.

Key material properties

• Strong gas barrier. The aluminium layer resists oxygen, water vapour and other gases, which keeps contents fresh and extends shelf life — the property converters rely on in high-barrier food formats.
• Light and radiant-heat reflection. The bright metallic surface reflects light and radiant heat, protecting contents that are sensitive to light and adding a degree of insulation in brief-heat situations such as hot-food delivery.
• Low metal weight, converting-friendly. Because the layer is only about 0.02–0.04 μm, metal per square metre is a small fraction of foil-laminated paper; the sheet stays light and flexible and slits, folds and forms cleanly.
• Printability and gloss options. The aluminium surface accepts printing and is supplied in several metallic gloss levels, so the finish follows the package design.
• Broad base-paper range. The process runs on base papers and boards from light papers to heavier boards, so the barrier is graded to the package type.
• Food-contact suitability. Food-contact-suitable grades meet international food-contact safety requirements; supporting compliance documentation is available offline on request.

Supply forms and custom converting

• Rolls or sheets.
• Multiple aluminised gloss options.
• Multiple base-paper options (white or coloured papers and boards).
• Custom widths, grammage and printing on request.

Coated and barrier grades are coated or laminated on our own lines and supplied in rolls or sheets. For water-based coated aluminized paper, width, sheet size and roll length follow the line the paper feeds.

Slitting, rewinding, sheeting and printing are carried out on our own converting lines. Send the line the paper runs on and the form you need; grade, grammage and tolerance are confirmed before quoting. Custom paper converting

Typical end uses

Because it combines a strong gas and light barrier with good converting behaviour, water-based coated aluminised paper is commonly converted into:

• Inner liners for takeaway and food-delivery bags
• Cold-chain and hot-food-delivery bag liners
• High-barrier wrappers and sachets for bakery, dry food, snacks, coffee and tea
• Barrier liners and pouches for food-service and meal-delivery packaging

How to order and choose

Water-based coated aluminised paper is specified by base paper, grammage and metallic finish to match the end use and the converting line. Whether the liner will carry hot, chilled or light-sensitive food, tell us the bag or pouch format and the converting step, and we will recommend a starting grade. Request samples to trial on your own line.

Bofeng New Materials supplies water-based coated aluminised barrier paper, in rolls or sheets, to converters and food-packaging producers worldwide.

Fluorine-free construction. The coating is a water-based system and contains no fluorochemical greaseproof agent. For EU food-contact packaging — where PFAS restrictions apply from 12 August 2026 — tell us the destination market and we will confirm the grade and the documents you need. Compliance documentation is provided offline on request; we do not publish certificate numbers online.
