Carton liner for passive cold chain parcel packouts

These insulated box liners are designed to sit inside a shipping carton and create a passive insulation barrier around the payload. EPE foam adds cushioning, aluminum foil reflects radiant heat, and widened edge sealing plus adhesive flap options help packing teams close the liner quickly.

Carton ready liner

The liner turns a standard corrugated box into a more protective insulated packout.

EPE cushioning

EPE foam helps cushion the payload while adding thermal resistance.

Aluminum foil surface

The reflective foil layer helps reduce radiant heat transfer inside the carton.

2D and 3D options

Choose envelope style liners for flat packing or 3D bag liners for easier loading.

Space saving storage

Foldable liners ship and store compactly before use.

Custom packout support

Tempk can customize size, foil print, sealing detail and carton matching.

Where it fits best

Food and seafood parcels

For meat, seafood, dairy, prepared food, produce and chilled grocery shipments.

Chocolate and confectionery

For heat sensitive chocolate, candy and bakery items in seasonal shipping.

Pharma and samples

For selected pharma samples or healthcare parcels after the complete packout is validated.

How to plan the packout

Match carton size

Select a liner size that fits the carton without leaving large gaps around the payload.

Place coolant by route

Add gel packs or ice bricks according to payload mass, route time and ambient exposure.

Close the liner

Fold or seal the flap before closing the carton to reduce air exchange.

Validate the packout

Test the complete carton, liner, coolant and payload combination before live shipping.

Customization support

Size and format

Customize 2D or 3D liner dimensions to match the buyer's carton.

Foil and foam

Adjust foil, EPE thickness, edge sealing and closure details.

Brand and packing

Support foil printing, instruction labels, flat packing and carton packing.

Handling instructions

Open the liner inside the corrugated carton, place the payload and conditioned coolant according to the tested layout, then fold or seal the liner before closing the carton.

Do not rely on the liner alone for a fixed temperature result. Final performance depends on carton size, payload, coolant, route time and ambient exposure.
