RYAM Expands Kallima Portfolio with Enhanced Freezer Application Folding Carton Board

Rayonier Advanced Materials Inc. (the “Company” or “RYAM”), a provider of High Purity Cellulose, is pleased to announce the introduction of its Enhanced Freezer Application for folding carton board, purpose-built to meet the packaging needs of the frozen food sector. This enhancement builds on RYAM’s trusted folding grade, ensuring converters and brand owners have a proven, reliable solution for frozen meals packaging.

Developed at RYAM’s Temiscaming facility, this advancement equips Kallima’s folding grade with the durability and performance required for cold-chain distribution. Engineered to withstand temperatures as low as -18°C (0°F), it maintains structural integrity and resists delamination in freezer conditions. Its natural resistance to moisture and condensation—without coatings or plastic extrusion—delivers cost efficiency, ease of converting, and sustainability benefits.

Key Benefits for Folding Box Converters:

• Reliable Cold Performance – Withstands industry-standard freezer conditions without compromise.
• Moisture-Resistant Design – Performs in high-humidity environments without added treatments.
• No Coatings Required – Simplifies converting and reduces costs by eliminating extrusions.
• Versatile Usage – Ideal for a range of frozen food applications, from ready meals to protein trays.
• Premium Print Surface – Supports high-quality graphics and consistent converting results.
• Sustainable Solution – Made from responsibly sourced, certified forest fiber.

“Our Enhanced Freezer Application is a direct response to customer needs,” said Ken Duffy, Senior Vice President, Paperboard and High Yield Pulp. “It empowers converters with a freezer-ready solution that performs reliably while remaining easy to convert—helping brands stay competitive without adding production complexity.”

This innovation comes as the frozen food market continues to grow worldwide, driven by consumer demand for convenience and extended shelf life. With the Enhanced Freezer Application, RYAM provides packaging manufacturers with a solution that safeguards product integrity while delivering on sustainability and operational efficiency.
