Caps and closures represent a significant opportunity within packaging, used across a wide range of applications and industries. Building on years of experience in Dry Molded Fiber, PulPac is now advancing fiber-based alternatives in this category, targeting one of the most widely used plastic components in everyday packaging and a key segment in the transition toward more material-aligned packaging systems. The new caps are designed to meet the functional and consumer expectations typically associated with plastic alternatives, while moving toward a fiber-based solution.
Early tests indicate promising performance across several key parameters, including thread engagement, opening and closing functionality, sealing architectures, and overall tactile experience. The caps also enable a high level of design flexibility, including the ability to differentiate the inside and outside of the cap, opening new possibilities for both function and brand expression.
The development is carried out together with PA Consulting and in close dialogue with industry stakeholders including PulPac’s designated machine partner for this segment, Optima. It also builds on ongoing work within the Bottle Collective initiative, where complete fiber-based bottle systems, including closures, are being explored and evaluated as integrated solutions, with participation from several global brand owners and packaging players.
