Reusable and high-performance insulated box programs
Configure the usable payload chamber, EPP shell, protected VIP arrangement, lid and handles, cold-source compartments, dividers, logger position, cleaning process, labels, and repeat-order specification around your product and route.
Prepare your sample request
Select the requirements your quality, logistics, procurement, and packing teams already know. The result narrows a starting structure; it does not replace qualification of the complete loaded shipper.
What needs to be customized?
Choose the right structure
EPP, VIP, hybrid, and collapsible boxes suit different handling and return models. Select a starting structure, then confirm it with the complete payload, cold source, route, and operating procedure.
| Starting structure | Good fit when | What can be customized | Confirm before approval |
|---|---|---|---|
| Molded EPP box | The box will be handled, cleaned, returned, and reused on controlled regional routes. | Chamber, wall, lid, handles, divider, coolant slots, color, labels, and asset ID. | Loaded handling, cleaning, drying, stacking, return storage, seasonal packout, and retirement rules. |
| EPP with removable VIP liner | Impact protection, usable payload space, and replaceable insulation all matter. | Panel geometry, edge protection, liner retention, lid interface, chamber, and service access. | Panel protection, usable volume, cleaning boundaries, inspection, and replacement procedure. |
| Protected VIP shipper | High-value payloads, outer-size limits, long dwell, or demanding seasonal exposure justify higher-performance insulation. | Panel map, joints, lid, protective shell, coolant array, logger position, seal, and instructions. | Full and partial loads, summer and winter profiles, handling, panel inspection, and change control. |
| Collapsible VPU return box | Empty return volume matters and operators can repeat the foldable assembly correctly. | Fold lines, panel protection, closure, divider, coolant positions, return labels, and storage format. | Assembly repeatability, component inspection, cleaning, training, and return handling. |
Build the custom specification
Nominal litres do not show how much product will fit. Start with the packed payload, then reserve fixed space for every thermal and handling component.
Provide dimensions, unit count, orientation, secondary packaging, weight, and full or partial load patterns.
Define PCM, gel packs, or ice bricks, conditioning state, fixed positions, and required separators.
Set logger and sensor positions, start access, seal location, label visibility, and receiving steps.
Confirm lid clearance, compression, latches, cleaning, inspection, return storage, and replacement parts.
| Specification area | Decisions to provide | What approval should confirm |
|---|---|---|
| Box and insulation | EPP, VIP, hybrid, or VPU structure; dimensions; lid; handles; latches; shell; panel protection. | Fit, closure, loaded handling, stacking, panel safety, and the intended operating environment. |
| Payload and cold source | Product envelope, load patterns, divider, coolant type and state, positions, barriers, and seasonal variants. | Usable space, repeatable assembly, no unintended direct contact, and agreed sensor locations. |
| Identification and operation | Logger access, serial number, tamper seal, labels, cleaning, inspection, quarantine, repair, and return process. | Operators can pack, identify, inspect, release, and receive the correct configuration consistently. |
| Supply and records | Quantity, carton pack, pallet plan, spare parts, drawing, bill of materials, packout diagram, and revision. | The production sample and repeat-order records match the approved specification. |
Medical shipment controls
For medicines and vaccines, choose the container and packout from the approved product condition, route exposure, operating procedure, and evidence required by the buyer’s quality team.
EU GDP connects container selection with product requirements, medicine volume, temperature extremes, maximum transport or customs time, and qualification status. It also addresses qualified equipment and separation from cool-packs where direct contact creates risk.
Read Chapters 9.3-9.4WHO lists capacity, loaded weight, coolant model, cold or warm life, and the applicable test protocol for the specific container configuration. A material name alone is not a performance claim.
Review WHO E004ISTA 7E provides heat and cold profiles based on parcel-lane data for use when planning challenges for complete thermal transport packaging systems.
Review ISTA standardsImportant: EPP, VIP, or VPU material does not by itself establish WHO prequalification, GDP compliance, a universal hold time, or suitability for a specific medicine. Approve the exact loaded configuration and its operating procedure.
From requirements to repeat orders
The box, packout, test conditions, operating routine, and repeat-order records should move through approval together.
Confirm product limits, payload, route, exposure, reuse model, receiving, and acceptance evidence.
Compare EPP, protected VIP, hybrid, or VPU options using usable space and operating constraints.
Check the chamber, panels, coolant positions, divider, logger access, closure, labels, and packing sequence.
Challenge the complete shipper under agreed seasonal, delay, full-load, partial-load, and handling conditions.
Approve cleaning, inspection, return controls, drawings, parts, packout instructions, revision, and reorder code.

Questions before sampling
No. VIP is one insulation component. Suitability depends on the product requirement, payload, route, cold source, conditioning, separation, monitoring, operating procedure, and accepted evidence.
EPP is often practical for returnable regional routes that prioritize repeated handling, cleaning, molded features, low box weight, and a controlled return process.
There is no universal answer. Hold time depends on the exact loaded configuration, conditioning, ambient profile, openings, route, and acceptance limits. Request evidence for the configuration you intend to use.
Share the product condition, payload dimensions and weight, unit count, route and maximum duration, seasonal exposure, preferred structure, cold-source plan, reuse model, quantity, and required approval records.
Use the brief above or send the shipment details you already have. Tempk can review the starting structure, sample requirements, and quotation.
