Product Overview
A snack or coffee brand wants the reflective metal look without the weight and cost of aluminum foil. Metallized rollstock delivers it by vacuum-depositing a thin metal layer onto PET or BOPP, so the pack gets light barrier and aroma retention on a lighter, lower-cost web than a foil laminate.
The metallized layer is specified by optical density, which sets both the reflective appearance and the light barrier, and the structure is completed with the sealant layer your line needs. The metal sits inside a laminate where the structure calls for print on the outside, or the film is surface-metallized where a plain reflective web is enough.
Metallized films are used where a product is sensitive to light and aroma but does not need the absolute barrier of foil: snack pouches, confectionery wraps, coffee bags and tea packs. Metal adhesion is verified on the roll, and barrier values are confirmed on the actual structure rather than quoted from a generic data sheet.
Product Advantages
- Reflective shelf presence at a lower web weight, because a vacuum-metallized layer replaces a foil ply and cuts material weight.
- Light and aroma are held without foil, since the metal layer is specified by optical density and verified on the structure.
- Consistent metal appearance across orders, with optical density and metal adhesion checked per roll.
- One structure adapts across the range, so a flavor change is a print change rather than a new film.
Product Applications
- Snack and chip pouches with reflective branding
- Confectionery and chocolate wraps
- Coffee and tea bags needing aroma retention
- Powdered drink and dry mix packs
- Flow-wrap packs for bakery and convenience retail
FAQ
Is metallized film the same as aluminum foil laminate?
No. Metallized film carries a vacuum-deposited metal layer measured by optical density, while a foil laminate uses an aluminum foil ply. Metallized film is lighter and lower cost and is chosen where light and aroma barrier matter but the absolute barrier of foil is not required.
Does the metal layer affect print registration?
Print registration is set against the metallized surface in the same pass as a plain film. The metal side is confirmed before plate making, and color is proofed against the actual metallized shade.
Can a metallized roll run on a standard form-fill-seal machine?
Yes, when the sealant layer and roll geometry are matched to the line. Seal strength is tested on the target sealant layer, and winding direction is confirmed before the run.
How is the metal kept from cracking at the fold?
The metallized layer is specified and adhesion-tested so it stays bonded through folding and sealing. Structure and caliper are chosen against the pack format to avoid cracking on the fold line.
