1. Measure the erected carton
Record internal length, width and height at more than one point. Note board grade, flauta, flap layout and any bowed panels.
Made to fit your shipping carton
Custom Insulated Box Liners for Cold Chain Shipping
Turn an existing corrugated carton into a compact thermal shipper with a liner sized around the real box interior, carga útil, posições de refrigeração, closure and packing workflow.
Fit the actual cartonUse measured internal dimensions, not nominal outside size.
Protect usable volumeAccount for liner thickness, dobras, coolant and payload clearance.
Ship and pack efficientlyChoose flat-pack, kitted or pre-assembled supply.
Prepare a sample request
Build your insulated box liner specification
Enter the carton measurements and select the operating conditions that matter. Tempk can use this brief to prepare a liner structure and sample plan for fit and thermal review.
Suggested sample direction
Custom-fit folding parcel liner
Measure before material selection
Work from the carton interior to the usable payload chamber
The liner must fit the box and still leave enough room for product, refrigerante, dividers and closure. A nominal carton size rarely captures board thickness, manufacturing variation or flap interference.

2. Reserve space for the liner build-up
Espuma, bolha, board thickness, corner overlaps and top closure all reduce the clear internal chamber.
3. Check the loaded packout
Confirm payload removal, coolant clearance, controle de vazio, closure pressure and carton shape with the actual product format.
Use o Box Liner Sizing Tool to organize basic measurements. The final cutting size should still be confirmed from a physical sample or approved dieline.
Choose how the liner is assembled
Match the liner format to the packing station
Fold pattern affects corner coverage, tempo de embalagem, flat-pack volume, moisture paths and how consistently operators can close the carton.
One-piece folding liner
A scored liner opens inside the carton and reduces the number of loose parts at the packing station.
- Best starting point
- Repeat parcel cartons with a stable size and a simple loading sequence.
- Confirmar
- Fold memory, sobreposição de canto, top closure and flat-stack height.
Multi-panel liner set
Separate panels can adapt around unusual carton proportions or create different wall and lid constructions.
- Best starting point
- Large cartons, low initial volumes or projects comparing insulation combinations.
- Confirmar
- Part count, marcas de orientação, lacunas, assembly time and missing-panel risk.
Pouch or foil-board insert
A pouch can simplify moisture containment; a foil-laminated board insert can add shape and defined folds.
- Best starting point
- Wet loads, small parcels or packouts that need a more self-supporting cavity.
- Confirmar
- Seam position, risco de perfuração, drenagem, lid overlap and product removal.
Define what will be quoted
Specify the liner as a complete supplied component
Material name alone is not enough for repeat purchasing. The drawing, layer construction, dobras, costuras, tolerances and packing method should be controlled together.
| Item de especificação | Choices to define | What to check in the sample |
|---|---|---|
| Carton and fit | Measured internal dimensions, carton board, liner outer dimensions, assembly clearance and orientation | Easy insertion without buckling, gaps or excessive outward pressure on the carton. |
| Thermal construction | Foil-faced EPE foam, folha de bolha, foil-laminated board or an agreed paper/fiber concept | Layer identity, grossura, edge condition, compression and consistency across panels. |
| Fold and seam | One-piece score pattern, conjunto de painéis, pouch seam, sobreposição de canto, lid style and joining method | No unintended open corner, snag, sharp edge or assembly ambiguity. |
| Controle de umidade | Surface film, sealed seam, saco de forro, base absorvente, leak containment and venting decision | Condensation path, wet-out, punção, label adhesion and carton strength after the route. |
| Coolant integration | Principal, side or base positions; bolsos; divisores; camadas de buffer; pack size and removal method | Stable coolant placement without crushing product or preventing closure. |
| Identificação | Logotipo, cor, liner size code, fold marks, part number, batch label and packing instruction | Operators can select, orient and fold the correct liner without guesswork. |
| Supply pack | Flat-stack quantity, bundle size, carton kit, padrão de palete, moisture wrap and storage condition | Acceptable warehouse cube, unpacking time, panel flatness and damage rate. |
Plan the supply form
Compare liner price with packing and freight volume
A liner that performs well but arrives in bulky pre-assembled form may create avoidable inbound freight and warehouse pressure. Review the full packing operation before approving supply.
Flat-packed
Lowest assembled volume at receipt and suited to palletized bulk supply. Check fold memory, operator setup time and bundle protection.
Carton kit
Liner and matching carton are packed as one controlled set. Check part identification, kit completeness and replenishment workflow.
Pre-assembled
Reduces folding at the shipping station but increases transport and storage cube. Check nesting, shape recovery and handling damage.
Approve the liner in stages
Check fit and operations before a loaded thermal trial
Separating fit, pack-station and performance checks makes design changes easier to understand and avoids spending a thermal test on a liner that operators cannot assemble consistently.
Cut sample
Confirme as dimensões, dobras, costuras, sobreposição da tampa, carton insertion and the minimum usable chamber.
Packing trial
Time the assembly, load real product and coolant, check closure pressure and observe operator errors.
Loaded temperature test
Use the agreed payload, starting conditions, refrigerante, ambient profile and sensor positions.
Transit review
Inspect liner movement, punção, wet-out, resistência da caixa, product condition and receiving steps.
From drawing to repeat supply
Develop the OEM liner around your real packout
Medir
Provide an erected carton, dimensões internas, board details and required payload space.
Choose structure
Set the material direction, padrão de dobra, encerramento, moisture control and coolant positions.
Cut sample
Review fit, conjunto, volume utilizável, labels and the loaded packing sequence.
Test packout
Check the agreed thermal route plus handling, condensation and carton integrity.
Release order
Approve the drawing, tolerâncias, bundle quantity, pallet pack, artwork and reorder code.

Custom box liner questions
Should I send the carton outside or inside dimensions?
Send measured internal length, width and height from an erected carton. Also provide the outside size, board grade or dieline when available so fit and shipping cube can be reviewed together.
How much payload space will the liner remove?
That depends on material thickness, dobras, corner overlaps, lid design and assembly clearance. Tempk can confirm usable chamber dimensions on the cut sample rather than relying on a generic deduction.
Which liner material is best?
The choice depends on route duration, condição alvo, umidade, manuseio, required rigidity, metas de descarte, packing speed and cost. Compare the complete packout under the intended route conditions.
Can liners be supplied flat-packed?
Sim. Folding and multi-panel liners can be bundled flat to reduce storage and inbound freight volume. Bundle size, fold recovery and assembly time should be approved with the sample.
Can Tempk add a logo or folding instructions?
Identification labels, size codes, marcas de orientação, printed instructions and selected branding options can be included after the liner drawing and supply pack are confirmed.
Do custom liners include coolant?
The liner can be designed around defined gel packs, tijolos de gelo, PCM or other suitable coolant positions. Coolant quantity and placement should be confirmed with the actual payload and route test.
