Haleon and Bayer Join New Blister Sustainability Initiative

The Blister Pack Collective features a timeline on its site denoting proof of principles on commercial equipment, integration of lidding and barrier, and more. PA Consulting designed the workplan to have value for both consumer health and pharmaceutical companies participating in the Blister Pack Collective, says Thornley. “That design includes critical flexibility—if the product currently goes in a blister pack, we are confident it makes sense to consider Dry Molded Fiber (DMF).” 

Barrier: In terms of shelf-life and barrier against oxygen and moisture, the Collective will be working directly with members to design packs that match their specific product barrier requirements. “To-date, we’ve done sufficient research and prototyping to have high confidence that in the near term our DMF packs should be able to match performance of common PVC/Alu packs. And long-term, we are investigating approaches that should enable us to have solutions for products with even the most aggressive barrier requirements (e.g., U.S. Pharmacopeia Grade A),” he added.

Recycle-readiness: When asked if barriers might compromise recyclability, Thornley said, “For solutions with additional barrier layers beyond DMF, paper stream recycling should not be impacted.  Physical sortation and reprocessing trials are pending to confirm. In addition, as the portfolio of suitable barrier and lidding options continues to expand, our approach will allow for easy incorporation of these materials so we are always future fit.”

Lidding choices will be based on product requirements and desired consumer/patient experience—at present it is assumed most lidding will be paper-based. 

Equipment: Whether a material can run on existing machinery plays a role in how likely it is to be adopted. Many companies aren’t ready to purchase entirely new machines or lines to accommodate a package with improved sustainability attributes. The DMF blister architecture is being designed to be compatible existing filling, lidding, and cutting equipment to minimize expenditure and changes to current manufacturing processes, says Thornley. “We will work in close collaboration with both the collective members and equipment suppliers to ensure plug-and-play wherever possible. The DMF process is suitable to both recycled pulp and other fiber inputs, including agricultural waste streams… We look forward to working on those challenges after demonstrating the foundational technology.”

As Jesse DelGigante, director global packaging innovation at Bayer Consumer Health, explains, “We have a bold commitment to transform 100% of our packaging to be recyclable or renewable by 2030 and have committed to invest €100 million investment in changing how our products are made and consumed. Achieving this will require working with the best partners and we are proud to be a part of the Blister Pack Collective as we work to make a real impact for sustainability.”

Leading companies like Haleon and Bayer Consumer Health lend validation to DMF's potential. Sanna Fager, chief commercial officer at PulPac, says, “By joining forces, we can move faster and tackle challenges collaboratively and effectively. When we started PulPac, we set out to replace single-use plastics at scale by building an ecosystem of changemakers around Dry Molded Fiber. We are excited to see that vision come to life and be embraced by the industry.”
