Description

These 18 x 18 x 18" insulated box liners are built in a one-piece gusseted format that sets up quickly and fits standard corrugated shippers of the same dimension, converting them into temperature-controlled containers without requiring a pre-fabricated insulated box.

FDA-compliant materials rated for incidental food contact make these liners well-suited for perishables, meal kit components, specialty foods, pharmaceuticals, and nutraceuticals. The leak-resistant construction guards against condensation and minor coolant leakage when used alongside cold packs or gel ice — a practical safeguard in direct-to-consumer and B2B cold-chain fulfillment alike.

Each case contains 10 liners. The liner material is parcel-friendly and weighs approximately 7.18 lbs per case, keeping shipping costs predictable for both small replenishment orders and scheduled warehouse restocking.
