Reliable Foil-Lined Foam Shipping Boxes Manufacturer
For Cold Chain Packaging

The reflective foil surface helps reduce radiant heat transfer, while the foam core slows conductive heat transfer through the walls of the box. Used together, these materials help maintain a more stable internal environment than a standard corrugated shipping carton. The box does not actively refrigerate the contents, so ice packs, gel packs, phase-change materials, or dry ice may still be required.

The foil-lined interior provides good resistance to condensation and minor moisture exposure. However, the complete box should not automatically be described as fully waterproof unless the outer corrugated carton also uses a moisture-resistant coating or laminated barrier. For seafood, ice-packed products or high-condensation environments, we can add a water-resistant outer carton, liner or leak-control solution.

GPPS foam is lightweight, rigid and widely used as a thermal-insulation and cushioning material. For export orders, buyers should confirm destination-specific requirements concerning packaging materials, recycling labels, food-contact use and environmental regulations. We can provide available material specifications, product declarations and supporting documents for customs review.
