Thermoformed from FSC-certified virgin wood fibers under precise mechanical compression. Cured with an organic, PFAS-free hydrophobic bio-barrier providing full meltwater containment without internal plastic films.
Fiber Box Large (26L / 27.5 Qt)
Heavy-Duty Master Cold-Chain Shipper for Whole Fish & Bulk Freight
The Large 26L format is engineered for high-capacity perishables: whole commercial finfish, bulk shellfish sacks, sub-primal meat cuts, and regional distribution routes. Designed on a modular 2-on-1 footprint with the Medium box, it nests 120 boxes per pallet and sustains 150 to 180 kg scaled compressive loads.
