1. Measure the erected carton
Record internal length, width and height at more than one point. Note board grade, flute, flap layout and any bowed panels.

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, حمولة, coolant positions, closure and packing workflow.
Fit the actual cartonUse measured internal dimensions, not nominal outside size.
Protect usable volumeAccount for liner thickness, طيات, 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, سائل التبريد, dividers and closure. A nominal carton size rarely captures board thickness, manufacturing variation or flap interference.

2. Reserve space for the liner build-up
رغوة, فقاعة, board thickness, corner overlaps and top closure all reduce the clear internal chamber.
3. Check the loaded packout
Confirm payload removal, coolant clearance, السيطرة على الفراغ, closure pressure and carton shape with the actual product format.
استخدم 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, وقت التعبئة, 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.
- أفضل نقطة انطلاق
- Repeat parcel cartons with a stable size and a simple loading sequence.
- يتأكد
- Fold memory, corner overlap, 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.
- أفضل نقطة انطلاق
- Large cartons, low initial volumes or projects comparing insulation combinations.
- يتأكد
- Part count, علامات التوجه, الفجوات, 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.
- أفضل نقطة انطلاق
- Wet loads, small parcels or packouts that need a more self-supporting cavity.
- يتأكد
- Seam position, خطر ثقب, الصرف, 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, طيات, طبقات, tolerances and packing method should be controlled together.
| البند المواصفات | 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, احباط فقاعة, foil-laminated board or an agreed paper/fiber concept | Layer identity, سماكة, edge condition, compression and consistency across panels. |
| Fold and seam | One-piece score pattern, مجموعة لوحة, pouch seam, corner overlap, lid style and joining method | No unintended open corner, snag, sharp edge or assembly ambiguity. |
| مراقبة الرطوبة | Surface film, sealed seam, حقيبة بطانة, قاعدة ماصة, leak containment and venting decision | Condensation path, wet-out, ثقب, label adhesion and carton strength after the route. |
| Coolant integration | قمة, side or base positions; جيوب; المقسمات; طبقات عازلة; pack size and removal method | Stable coolant placement without crushing product or preventing closure. |
| تعريف | الشعار, لون, 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, نمط البليت, 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
تأكيد الأبعاد, طيات, طبقات, تداخل الغطاء, 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, سائل التبريد, ambient profile and sensor positions.
Transit review
Inspect liner movement, ثقب, wet-out, قوة الكرتون, product condition and receiving steps.

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, طيات, 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, حالة الهدف, رُطُوبَة, التعامل, required rigidity, disposal goals, packing speed and cost. Compare the complete packout under the intended route conditions.
Can liners be supplied flat-packed?
نعم. 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, علامات التوجه, 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, طوب الجليد, PCM or other suitable coolant positions. Coolant quantity and placement should be confirmed with the actual payload and route test.
Ready to fit an insulated liner to your carton?
Share the erected carton dimensions, حمولة, طريق, سائل التبريد, moisture exposure and order quantity. Tempk can prepare a liner sample direction and OEM quotation.
