Closing the Loop on Sustainability with Tri-Sure Closures and Caps

Every detail matters when it comes to sustainable packaging. With Tri-Sure® closures, caps, and linings, customers can reduce emissions, meet stricter regulations, and protect product integrity without compromising performance. Our accessories turn a standard steel drum into a smarter, more sustainable solution.

Sustainable Caps with Recycled Content

Tri-Sure also offers the EcoBalance™ SambaCap™, produced from 100% post-consumer recycled resin. Independent testing shows up to a 45% reduction in closure-level CO₂ emissions compared to standard plastic caps. Available in common drum sizes, they install easily and provide tamper resistance for added product protection.

BPA-No Intent Linings for Safer Chemistry

For industries where product purity is critical, Tri-Sure supports BPA-no intent linings. These linings avoid the intentional use of bisphenol A (BPA), aligning with evolving health and regulatory standards while maintaining the performance required for demanding applications.

Safer Closures with Cr(III) Passivation

For decades, drum closures were treated with hexavalent chromium (Cr(VI)), a substance now heavily restricted due to its health risks. Tri-Sure transitioned nearly a decade ago to trivalent chromium (Cr(III)) passivation. Easily identifiable by its platinum finish, this solution gives customers peace of mind that closures meet global regulatory expectations while protecting product integrity and protecting people and the environment.

Why Accessories Matter

Closures, caps, and linings may be small parts of a steel drum, but they have an outsized impact on sustainability, compliance, and customer confidence. By specifying Tri-Sure components, companies can make meaningful progress toward lowering Scope 3 emissions, improving material safety, and meeting global regulations without compromising reliability or performance.

At Tri-Sure, we are committed to helping our customers build more sustainable packaging systems, one component at a time. Contact us today to learn more about our sustainable accessories and how they can support your packaging goals.
