RYAM unveils moisture-resistant freezer board for frozen food packaging

USA – Rayonier Advanced Materials (RYAM) has introduced an advanced freezer-grade folding carton board designed specifically for the frozen food sector. 

Developed at the company’s Temiscaming facility in Canada, this new product belongs to RYAM’s Kallima folding grade line and meets the demands of cold-chain logistics without relying on additional coatings or plastic extrusion processes.

The board withstands temperatures as low as -18°C (0°F), maintaining its structure and preventing delamination during prolonged freezer storage and transport. 

This capability stems from innovative fiber treatments that enhance moisture barriers, reducing production costs for converters and streamlining manufacturing steps. 

Suitable for applications like ready-to-eat meals and protein trays, the material draws from fibers sourced from certified, responsibly managed forests, ensuring traceability in its supply chain.

Ken Duffy, RYAM’s senior vice-president for paperboard and high-yield pulp, highlighted the practical advantages in a recent statement. 

He noted that the development directly addresses converter challenges in handling frozen goods, providing a reliable option that cuts down on extra processing time. 

Duffy added that brands can now meet consumer expectations for durable packaging while keeping operations straightforward.

This launch comes amid growing pressure on the packaging industry to reduce plastic use, particularly in food sectors where traditional barriers often involve polyethylene layers. 

By eliminating those extras, RYAM’s solution lowers material expenses, estimated at up to 15% savings per unit for high-volume runs—and eases recyclability at end-of-life.

The board’s surface also supports high-quality printing, allowing for vibrant graphics that enhance shelf appeal in retail freezers.

RYAM, which operates mills across the US, Canada, and France, reported US$1.6 billion in revenue for 2024. Its product range spans cellulose specialties for filters, pharmaceuticals, and food additives, alongside paperboard options for broader packaging needs. 

The company has invested over US$50 million in recent years to upgrade its facilities, focusing on sustainable fiber processing that minimizes water and energy use.

In parallel developments, Huhtamaki expanded its Fiber Foodsafe range in September 2025 with a new paper-based barrier for frozen products, achieving full recyclability while blocking grease and moisture at costs comparable to conventional options. 

A company spokesperson explained that this move supports Middle East markets by integrating local recycled content, targeting a 20% reduction in virgin plastic across supply chains by 2027.

Such innovations signal a broader shift toward fiber alternatives in the region, where frozen food demand has surged 12% annually due to urbanization.

RYAM’s entry strengthens options for global brands seeking compliant, eco-conscious packaging. 

Converters have already tested the board in pilot runs, confirming its performance in real-world distribution cycles from warehouse to store.
