Overview
A barrier built for aggressive fills
Some contents attack a standard seal layer. Solvents, acids and oils can soften or delaminate an ordinary liner, so this family pairs aluminium foil with high-barrier COEX structures that hold their weld against demanding agrochemical, lubricant and condiment formulations.
Where the container is glass, a glassy hot-melt grade takes over. It welds directly to the jar mouth, giving foods, condiments and personal-care fills a tight, moisture-resistant closure. Tell us what you fill and the container type, and we match the barrier to the chemistry.
How it is built
A layered structure, drawn to spec
A high-barrier liner keeps the same foil-at-the-heart build, with a COEX barrier layer that holds its weld against solvents, acids and oils in demanding fills.
Why this family
What a high-barrier liner holds up against
Glass sealing
Glassy hot-melt grades that weld to glass jars for food, condiment and personal-care fills.
Keeps contents stable
Strong barrier and moisture resistance that extends shelf life.
Die-cut Ø 9–182 mm
Matched to your container mouth, printed or embossed on request.
Variants
Pick the barrier by the chemistry
Two build paths cover the demanding fills: a high-barrier COEX laminate for aggressive liquids, and a glassy hot-melt grade for glass containers.
