Best use cases
Use this tool when the package size is the main question
Many cold-chain projects fail early because carton liners are too tight, pallet covers do not account for wrap and corner build-up, or the sizing request does not separate usable inner space from finished outside dimensions.
Thermal pallet cover sizing
Use pallet cover mode for palletized freight, airport transfer, warehouse dwell, export handling, outdoor staging, or thermal protection around wrapped bulk cargo.
Carton + pallet-level protection
Use both modes when the shipment needs carton-level insulated liners and a pallet cover for bulk consolidation, tarmac exposure, or warehouse holding risk.
Sizing tool
Build your liner or pallet cover size reference
Enter your carton or pallet-load information below. The tool provides a sizing reference for quotation review. Final specifications should still be confirmed with real cartons, pallet builds, cold-source layout, closure method, samples, and route testing.
Planning note: Measure actual cartons and pallet loads before production. Include liner thickness, top pad, flap overlap, stretch wrap, corner compression, and handling allowance. For dry ice, do not specify airtight structures; packaging must allow gas release. For pharma or lab lanes, confirm logger placement, SOPs, qualification, and validation requirements.
Enter carton or pallet-load dimensions below. The tool returns a sizing reference for RFQ review, not a validated thermal qualification result.

How to use it
A simple workflow for liner and pallet cover sizing
Follow these steps when preparing dimensions for the sizing tool. Each step helps build a more complete sizing reference before your RFQ.
| Step | What to enter | Why it matters |
|---|---|---|
| 1. Choose sizing mode | Select box liner, pallet cover, both, or auto-decision by dimensions. | This separates carton liner projects from pallet cover projects and avoids using pallet-style calculations for small parcel cartons. |
| 2. Enter dimension basis | Use existing carton inner dimensions, required usable payload space, or finished pallet-load outside dimensions. | Usable inner space and finished outside dimensions mean different things; the tool adjusts sizing logic accordingly. |
| 3. Add material and fit assumptions | Enter liner thickness, clearance profile, top overlap or flap allowance, material preference, and cover style. | Thickness, clearance, flap design, and cover style affect fit, loading speed, closure, and sample review. |
| 4. Review route guardrails | Check cold source, outdoor staging, dry ice, pharma, logger, and custom OEM fields. | Cold-chain sizing is not only geometry; route risk and validation needs influence material and design review. |
| 5. Copy the RFQ summary | Use the result summary for custom liner, pallet cover, sample, MOQ, or bulk quote discussion. | A clear dimension summary reduces back-and-forth before production sampling. |
Decision guide
Box liner, pallet cover, or both?
The sizing output depends on whether the packaging protects individual cartons, a complete pallet load, or both levels of a cold-chain shipment.
| Shipment profile | Likely sizing path | Next action |
|---|---|---|
| Small parcel carton, meal kit, grocery, fresh food, or pharma sample shipper | Insulated box liner sizing | Calculate liner fit, usable inner space, top pad, and cold media placement needs. |
| Carton-based e-commerce program with repeated custom sizes | Panel-set or foldable liner reference | Prepare sample dimensions, thickness, material grade, flap style, and packing process notes. |
| Wrapped pallet load, airport transfer, warehouse dwell, or bulk cold-chain freight | Thermal pallet cover sizing | Calculate cover width, depth/gusset, drop height, skirt allowance, clearance, and material area. |
| Export route with tarmac, outdoor staging, or customs dwell risk | Pallet cover + route-risk review | Use Route Risk Checker and confirm reflective layers, moisture resistance, and handling controls. |
| Frozen, dry ice, or deep-frozen shipment | Insulation sizing + cold source review | Size the liner or cover here, then confirm cold source mass in the Dry Ice Calculator or Ice Pack Calculator. |
| Pharma, vaccine, lab, or high-value regulated shipment | Qualified packaging review path | Use the sizing result as a sample reference, then confirm SOPs, data loggers, qualification, and validation. |
Sizing rules
Important sizing rules before you request samples
These practical rules help buyers understand the difference between a clean online estimate and a production-ready custom packaging specification.
Do not size every liner or cover too tight
Snug fit can help reduce dead space, but production sizing must still allow for liner thickness, carton tolerance, loading method, stretch wrap, pallet corner build-up, and repeated manual handling.
Insulation sizing is not cold-source sizing
Box liners and pallet covers slow heat transfer, but they do not replace gel packs, PCM, ice bricks, dry ice, refrigerated transport, or validated cold-source planning.
Use samples before locking production dimensions
Final specifications should be checked with real cartons, pallet builds, cold media, data logger placement, product loading, closure method, route testing, and production samples.
Result meaning
How to interpret the sizing result
The calculator result is designed to help purchasing, logistics, QA, and supplier teams discuss the same dimensions without confusion.
Liner fit and usable inner space
The result separates carton fit from usable payload space so buyers can understand how liner thickness and top pad choices affect the internal packing area.
Cover width, depth, drop height, and skirt
The result gives a starting reference for a slip cover, full-drop cover, top cap, or roll-stock wrap sheet, including practical clearance and handling assumptions.
Route and material review points
The result may flag dry ice venting, rain or sunlight exposure, tarmac staging, pharma logger needs, frozen-lane cold-source review, or custom OEM notes.

Why liner and pallet-cover sizing matters in cold-chain logistics
Cold-chain packaging size is not only a packaging dimension issue. A liner that is too tight can reduce usable space, compress cold packs, create closure problems, or make warehouse packing inconsistent. A pallet cover that is too short or too loose may leave thermal bridges around the load, allow heat gain during staging, or make repeated handling difficult.
For food and fresh products, packaging and temperature control help reduce quality loss during transport. For pharmaceutical and lab shipments, packaging decisions should also support SOPs, monitoring, and qualification work. For air freight or export routes, pallet covers may need to account for tarmac exposure, warehouse dwell, customs delay, and handling by multiple logistics partners.
Use this tool as a first sizing step, then confirm the final specification with Tempk samples, real pack-out testing, and route-specific review.
FAQ
Box liner and pallet cover sizing FAQs
Common questions from buyers comparing insulated liners, pallet covers, carton fit, and cold-chain packaging options before requesting samples or a custom quote.
Is this a final production specification?
No. The result is a quotation and planning reference. Final production specifications should be confirmed with real cartons, pallet builds, liner thickness, closure style, cold media placement, samples, and route testing. For technical documents and test support, review Tempk technical documentation.
When should I use box liner sizing?
Use box liner sizing when your shipment uses a corrugated carton or shipping box and needs a foldable foil liner, foam liner, panel set, or insulated insert to reduce heat transfer. This is common for fresh food e-commerce, meal kits, seafood, chocolate, dairy, pharmaceuticals, and lab samples. You can also read Tempk's insulated box liner guide or browse Insulated Box Liner products.
When should I use pallet cover sizing?
Use pallet cover sizing for palletized freight that may face warehouse dwell, airport or tarmac exposure, cross-docking, export handling, outdoor staging, or repeated transfer between logistics partners. Pallet covers help reduce heat gain or heat loss around the full pallet load. See Thermal Pallet Covers, the Insulated Cargo Pallet Cover, or the Reusable Waterproof Pallet Cover.
Why does clearance matter for liners and pallet covers?
Thermal liners and pallet covers should not be specified too tightly. A proper fit allowance helps account for liner thickness, cold packs, top flaps, stretch wrap, pallet corners, compression, manual loading, and repeatable warehouse handling. If you are not sure which packaging family is right, start with the Packaging Selector.
Does this replace ice pack or dry ice calculation?
No. This page sizes the insulation structure. You should estimate cold-source needs separately with the Ice Pack Calculator or Dry Ice Calculator, then confirm the complete pack-out with samples and route testing.
Can this sizing tool support pharma or lab shipments?
Yes, as a planning tool. Pharma, biologics, vaccine, and lab lanes should also include SOP review, logger placement, qualification, and route-risk assessment before final approval. Tempk can help connect liner or pallet-cover sizing with EPP boxes, VIP Medical Cool Boxes, ice bricks, and documentation support. See also the Pharma Cold Chain Logistics guide, Route Risk Checker, or Compliance Checklist Generator.
