Heat Seal Aqueous Lacquer for Blister Packs

A heat seal aqueous lacquer for blister packs is a functional coating with a job that is easy to state and demanding to achieve: when a printed blister card is heat-sealed to a blister the seal must hold every time through packing transport retail display and consumer use.

Triwill Group supplies Blister Coating through partners and distributors in the UAE and GCC, on a quote-led basis. Technical data sheets are available on request, with a technical and commercial study behind each recommendation.

Key Features

• Reliable heat sealing: Formulated to activate under heat and pressure to form a strong, consistent bond between blister card and blister material.
• Production consistency: Designed to give repeatable seal strength across a production run, when applied and sealed within the recommended conditions.
• Print-compatible surface: A printable card surface that carries branding, product information and regulatory text, while also functioning as a heat-seal layer.
• Waterbased formulation: A lower-odour aqueous coating suited to modern coating units and to pharmaceutical and retail packaging production where solvent coatings are best avoided.
• Tamper-evident pack integrity: A strong seal that helps protect the product and provides tamper evidence until the consumer deliberately opens the pack.

Frequently Asked Questions

What is a heat seal aqueous lacquer for blister packs?

A waterbased coating applied over printed blister card, formulated to become adhesive under heat and pressure during heat sealing, bonding the card to a formed blister to enclose the product in a strong, tamper-evident pack.

How does heat sealing work?

The coated card is placed against a formed blister, and heat and pressure are applied through a sealing platen or roller. The heat activates the lacquer film, which bonds to the blister material, and as the seal cools, a strong bond forms between card and blister.

Will it seal to my blister material?

That depends on the specific blister material, card stock, coating weight and sealing conditions.

How is seal strength tested?

Trials should cover the full range of sealing temperatures, pressures and dwell times the line will use.
