Heat-Free, Eco-Friendly Secondary Blister Packaging
Pharmaceutical manufacturers are under dual pressure: reducing single-use plastic packaging waste while protecting delicate active pharmaceutical ingredients (APIs) from thermal degradation. Traditional heat-sealed blister clamshells require high sealing temperatures (140°C to 180°C) that risk degrading live probiotic strains, peptides, and temperature-sensitive molecules.
1. The ColdSeal Advantage
ColdSeal Blister Wallets bond two coated paperboard layers utilizing cohesive pressure pinch-rollers without applying thermal heat. The drug cavity remains at room temperature throughout packaging, ensuring 100% API potency preservation.
2. 50% Plastic Reduction
By replacing heavy thermoformed plastic clamshells and vinyl packaging with certified FSC virgin paperboard, ColdSeal reduces plastic consumption by up to 50% while offering superior recyclable credentials.
3. Built-In Dose Adherence & Child-Resistance
ColdSeal wallets provide an expansive paperboard canvas for printed day-by-day calendar grids (7-day, 14-day, 28-day) that dramatically improve patient therapy adherence. Furthermore, child-resistant push-tab locking mechanisms can be integrated to meet ISO 8317 safety compliance.
