These 20 x 20 x 20" insulated box liners convert standard corrugated boxes into temperature-controlled shipping containers using a one-piece gusseted design that sets up in a single step with no assembly required. FDA-compliant materials rated for incidental food contact make these liners suitable for perishable goods that require cold chain compliance.

These liners are used alongside cold packs or dry ice in meal kit fulfillment, specialty food distribution, pharmaceutical shipping, and floral logistics — any application where maintaining a controlled temperature window during transit is critical. The leak-resistant construction contains condensation and melt water, protecting box integrity throughout the shipment.

Each case weighs approximately 8.88 lbs, providing substantial insulating mass without excessive added weight. Cases contain 10 liners and ship via parcel carrier.
