RYAM Expands Kallima® Portfolio with Enhanced Freezer Application Folding Carton Board

Rayonier Advanced Materials Inc. (RYAM) has introduced an enhanced freezer application for its Kallima® folding carton board, designed specifically for the frozen food packaging market. Developed at RYAM’s Temiscaming facility, this new product withstands freezer temperatures as low as -18°C (0°F), maintaining structural integrity and resisting delamination without needing coatings or plastic extrusion. The moisture-resistant design offers cost efficiency, ease of converting, and sustainability benefits by using responsibly sourced forest fiber. This innovation addresses growing consumer demand for convenient, long-lasting frozen foods while delivering premium print quality. Ken Duffy, RYAM Senior VP of Paperboard and High Yield Pulp, emphasized that this solution empowers converters and brand owners with reliable and sustainable packaging optimized for cold-chain distribution.
