Oyster 4T, Chilltainer, 410mm x 335mm x 170mm

The Oyster 4T Chilltainer is a high-performance insulated carton built for businesses that need to keep perishable goods chilled and fresh in transit. Measuring 410mm x 335mm x 170mm with a 23-litre capacity and a 12–16kg weight rating, it's a versatile size suited to seafood, produce, dairy, and other temperature-sensitive products moving through your supply chain.

Constructed from corrugated cardboard with a reflective metallised polyester coating, the Oyster 4T delivers proven thermal performance that keeps contents in a chilled, fresh state for up to 48 hours. That extended hold time gives you the flexibility to ship further and reach more customers without compromising product quality, while reducing your reliance on gel coolant per box.

Designed for B2B, courier, and export use, the Oyster 4T erects quickly by hand or jig and packs flat to save on storage and freight costs compared with bulky polystyrene alternatives. Its durable, thermally efficient profile makes it a practical, presentable choice for any operation shipping chilled goods at scale.

Pair it with Chilltainer EcoMats to extend thermal efficiency even further and get more travel time out of every box. Order in volume to standardise your cold-chain packaging and streamline your dispatch process.
