The PharmaGuard blister pack, an innovation by Südpack Medica based in Switzerland, represents a significant leap in sustainable pharmaceutical packaging. Made entirely from polypropylene (PP), this recyclable solution offers an eco-friendly alternative to conventional blister packs that typically rely on materials like polyvinyl chloride (PVC) and aluminum. PharmaGuard has been recognized with several prestigious awards, including the Swiss Packaging Award 2024 in the Sustainability category, as well as the WorldStar Global Packaging Award 2024 and the German Packaging Award 2023.

Specifically designed for solid pharmaceuticals and nutraceuticals, the PharmaGuard blister is a mono-material structure, with PP webs used for both the top and bottom layers. This design ensures excellent sealability, optimal strength, and is available in a variety of thicknesses to accommodate different product requirements. By switching to recyclable PP, PharmaGuard reduces environmental impact without compromising on functionality.

A comprehensive life cycle assessment conducted by Sphera revealed that PharmaGuard blisters produce up to 47% lower carbon emissions compared to traditional PVC and PVDC-coated aluminum blisters. In addition, PharmaGuard uses less energy and water during production.

PharmaGuard blisters are also designed to run on standard packaging equipment with minimal adjustments. They offer high transparency, reliable sealing, and a broader temperature range for sealing, providing enhanced flexibility and processing ease. The lower web of the blister, engineered for optimal thermoforming, creates uniform cavities that securely hold tablets or capsules, while also ensuring child-resistant features and ease of access for elderly patients.

In terms of product protection, PharmaGuard’s coextruded materials provide robust barriers against moisture, oxygen, and UV light, safeguarding the stability of sensitive medications. As Michael Hermann, Head of R&D at Südpack Medica, explains, the challenge lies in balancing ease of use for patients with robust child-resistant properties, a balance achieved through extensive application expertise and innovation.

This next-generation packaging not only exemplifies a commitment to sustainability but also ensures quality and functionality, meeting the evolving needs of the pharmaceutical industry and advancing the industry’s shift towards greener, recyclable solutions.
