Your partner, from start to finish.

As a specialist for thin-walled plastic packaging via the Weidenhammer acquisition, Sonoco supports you from the very beginning when it comes to developing your products. From the initial idea, to the 3-D animations and high-quality prototypes, we work together with you on the implementation your marketing concepts. 

Barrier In-Mould Labeling (IML)

Sonoco now offers a new barrier injection moulded packaging solution for extended shelf life, available in a wide variety of shapes, including nestable options for efficient transport.

Barrier IML packaging combines robust product protection with trendsetting shelf appeal through eye-catching, full-body graphics. It offers a cost-effective alternative to metal and glass, and it provides a better moisture barrier than traditional multi-layer plastic packaging in a thin-walled package. Durable and lightweight, it's compatible with retort, hot-fill or gas-flush filling systems.

This offers you:

  • Protection: Tests have shown a dramatically reduced water vapor transmission rate (WVTR) compared to standard monolayer polypropylene packaging -- an improvement of greater than 80%.
  • Strength: The robust structure will survive the retort process.
  • Shelf appeal: Access to superior graphics and branding via a label that covers more of your packaging's surface area.
  • Efficiency: Choose a nestable design for supply chain optimization.
  • Simplicity: IML packaging offers a high barrier delivered via a monolayer structure.
  • Convenience: Lightweight and easy to open, packaging is ideal for on-the-go consumers.

PermaSafe®

Brought by our Weidenhammer acquisition, In-depth research and development in-house led to innovations in injection molding and the invention of the modern PermaSafe® barrier packaging, which is acclaimed as the next-generation tin can.

PermaSafe® is clearly superior to cans made out of tin, aluminum or glass when it comes to convenience, freshness appeal and display qualities.

The revolutionary combination of in-mould labeling, sealing properties and injection moulding opens a new dimension in product concepts and applications.
