A technical deep dive into next-generation sustainable top seal films
The transition toward sustainable packaging is accelerating, but performance expectations remain uncompromising. In this context, Top Seal 30% PCR has been developed as a technically advanced solution that integrates 30% post-consumer recycled (PCR) content while maintaining the functional and processing standards required by modern packaging lines.
This material is not an adaptation of existing films. It is the result of material engineering designed specifically to balance circular economy principles with industrial-grade performance.
Material composition and circular design
Top Seal 30% PCR incorporates recycled polymers derived from post-consumer waste streams, carefully selected and processed to ensure consistency, purity, and traceability.
The PCR fraction is integrated into a multilayer film structure that:
-
Preserves mechanical integrity comparable to virgin-based solutions
-
Ensures homogeneous material behavior across the web
-
Supports repeatable performance in high-volume production
By embedding recycled content directly into a high-performance structure, the film actively contributes to waste reduction and material circularity without altering standard converting or sealing processes.
Technical performance overview
Top Seal 30% PCR is engineered to deliver high mechanical reliability, combining tensile strength, puncture resistance, and dimensional stability to ensure consistent performance from sealing through distribution.
Its advanced seal layer guarantees excellent seal strength and a wide sealing window, maintaining full compatibility with existing top seal machinery and trays, with no need for process adjustments.
Despite the presence of recycled content, the film preserves high optical clarity, with controlled haze and a uniform surface that supports strong shelf impact and consumer confidence.
Fully printable up to eight colors with certified inks, Top Seal 30% PCR enables premium brand communication, making sustainability visible without compromising design quality.
Designed for the future of packaging, it proves that circular materials and high performance can coexist in a scalable, industrially reliable solution.
