Insulated box liner product FAQ
What is an insulated box liner used for?
An insulated box liner is placed inside a carton to improve thermal protection for chilled food, seafood, medicine, grocery and sample shipments.

Can Tempk make liners to match my carton size?
Yes. Tempk can support custom liner dimensions, material structure, thickness, pouch format and packing count based on your carton and payload.
Are insulated liners reusable?
Some structures can be reused when they remain clean and undamaged, but many parcel liner programs are designed for one-way shipping. The best option depends on the route model.
