Common questions
Will these liners work with standard 18 x 12 x 12 corrugated boxes?
Yes. These one-piece liners are engineered to fit snugly inside standard corrugated shipping boxes of matching dimensions, allowing you to convert any box into an insulated shipping container without purchasing expensive pre-made thermal boxes.
Are these liners FDA food-contact compliant?
Yes. The materials are FDA-compliant for incidental food contact. Always pair with approved cold packs and follow your distributor's cold-chain protocols to maintain product quality, taste, texture, and color during transit.
How much thermal protection do these liners provide?
The 3/16" bubble lining combined with aluminum foil exterior provides reliable insulation for typical 2-3 day shipments when used with cold packs. Performance depends on ambient temperature, insulation quality of cold packs, and packing density.
Can I order in bulk beyond one case for volume pricing?
Absolutely. These liners are sold by the case (25 units), and bulk orders qualify for wholesale pricing. Contact our B2B sales team for volume quotes and flexible delivery schedules tailored to your seasonal demand.
