Start with the approved product limits
The medicinal product owner defines the storage range and excursion criteria. Share those limits before coolant and insulation are selected.
Custom 2–8°C pharmaceutical packouts
Pharmaceutical 2–8°C Packaging for Your Shipping Route
A 2–8°C pharmaceutical packout combines an insulated shipper, correctly conditioned coolant, separation layers and temperature monitoring. Choose the combination around your medicine’s labeled limits, payload size and mass, journey length and seasonal exposure. Tempk can configure EPS, reusable EPP or VIP options for sampling and testing. A 2–8°C label or PCM melting point alone does not establish performance: the loaded system needs evidence for its intended conditions, including the risk of temperatures below the lower limit.

Prepare a sample request
Build your 2–8°C packaging brief
Select what your quality and shipping teams already know. The result is a starting configuration for sampling, not a replacement for the product label, stability data or route qualification.
Suggested sample direction
Compact refrigerated parcel set
Protect the payload chamber
Separate cooling capacity from direct cold contact
A 2–8°C packout must be assessed at more than one point. The warmest payload location can approach the upper limit while a carton beside a cold pack approaches the lower limit.

Layout illustration only. Coolant quantity, spacing and sensor positions must follow the tested configuration for your shipment.
Condition coolant by a written method
Follow a conditioning method for the selected coolant and tested packout: define the storage temperature, time, starting state and release check before packing. Water-based gel packs and PCM may need different preparation. There is no universal freezer setting or preparation time for every 2–8°C system.
Fix the separation layer
Use the specified divider or spacer to keep coolant away from medicine cartons and preserve the tested loading pattern. Separation alone does not prove freeze protection; assess the complete system under its intended conditions.
Map likely hot and cold locations
During development, measure likely warm and cold payload locations, a representative center point and the ambient profile. Use those results to choose monitoring positions. A logger near the box wall alone may not represent all medicine temperatures.
Need a quick comparison before you choose a coolant? Use the Coolant and PCM Reference, then confirm the final quantity and conditioning method through a loaded thermal test.
Choose a shipper family
Match the package to route risk and reuse needs
The smallest package is not always the lowest-risk package. Internal volume, insulation, coolant arrangement, handling and the intended evidence level should be reviewed together.
Insulated carton or EPS shipper
A practical starting point for defined domestic lanes and single-use parcel distribution.
- Customize
- Payload cavity, liner or EPS wall, coolant sleeves, separators, outer carton and instruction insert.
- Check closely
- Hot and cold points, closure fit, carton strength, condensation and dimensional weight.
EPP medical cooler
Suitable when a closed distribution loop can support cleaning, inspection, component reset and returns.
- Customize
- Molded cavity, handles, seal points, removable PCM panels, labels and return identification.
- Check closely
- Cleaning compatibility, latch wear, missing components and performance after repeated use.
VIP high-performance shipper
Consider for long routes, limited external size, export dwell or a demanding seasonal profile.
- Customize
- VIP geometry, protective shell, payload chamber, PCM array, access control and logger map.
- Check closely
- Panel protection, assembly tolerance, customs delay, recovery after handling and replacement rules.
Define what will be supplied
Turn the packout into a controlled purchasing specification
A complete RFQ identifies the physical parts and the instructions that make the system repeatable. Final values are set from the actual payload, route profile and test result.
| Specification item | Choices to define | Why it matters |
|---|---|---|
| Payload chamber | Usable dimensions, payload mass range, carton orientation, void control and access direction | Prevents an oversized cavity or changed loading pattern from altering the thermal result. |
| Insulation | EPS, EPP, liner, VIP or combined structure; wall thickness; outer carton; closure | Balances duration, external size, handling strength, reuse and unit economics. |
| Coolant or PCM | Phase range, pack size, quantity, conditioning method, sleeves and placement map | Controls available cooling capacity and the repeatability of the starting condition. |
| No-freeze separation | Buffer material, thickness, molded spacer, corrugated divider and minimum clearance | Reduces local overcooling near the product without removing needed cooling capacity. |
| Monitoring | Logger type, probe locations, indicator pocket, device protection and retrieval instruction | Connects the shipment record to the locations evaluated during development. |
| Identification and security | Label area, component codes, tamper-evident closure, serialized asset label and artwork | Supports correct pack selection, chain of custody and reuse tracking where required. |
| Packout documents | Conditioning instruction, visual packing sequence, component checklist and receiving steps | Helps different operators assemble and receive the same configuration. |
Choose the evidence level
Request the evidence your approval process needs
Ask which payload, conditioning method, ambient profile and journey duration a report covers. A fit sample checks assembly; a screening trial compares designs; documented testing records measured performance. Qualification requires an agreed protocol and review by your responsible quality team.
Evaluate low and high payload loads across the intended hot and cold ambient profiles, with an agreed allowance for transport delays. Confirm the acceptance limits before testing. Results apply to the configuration and conditions tested; changes in loading, coolant preparation or route require review.
Physical fit review
Confirm payload loading, component count, closure, logger access, labels and the packing sequence before thermal work.
Screening trial
Compare candidate insulation, PCM quantity, buffer layer and logger positions under a defined development profile.
Documented test
Request the fixed component list, payload mass and starting temperature, conditioning record, ambient trace, probe map, calibration information, repeat results and exceptions. Report the temperatures and time outside the agreed limits for each monitored payload location.
Qualification support
Prepare the packout components and records required by the customer’s quality plan. Product release and regulatory decisions remain with the responsible organization.
Protect repeat orders
Keep the approved configuration stable after launch
A good pharmaceutical packout is not only a successful first sample. It also needs clear component identity, packing discipline and a review path when the route or product changes.
Lock the component set
Use part numbers for the shipper, PCM packs, buffers, dividers, logger accessories, seals and instruction revision supplied with each order.
Control conditioning and assembly
Record freezer or refrigerator setpoints, conditioning time, release checks, packout sequence and maximum time out of controlled storage.
Review changes before reuse
Reassess when payload mass, carton geometry, route duration, ambient profile, carrier, coolant or insulation changes beyond the approved scope.

Pharmaceutical packaging questions
Can one 2–8°C packout be used for every refrigerated medicine?
No. Product limits, payload size, starting temperature, freeze sensitivity, route and receiving conditions differ. The responsible product owner should define the acceptance criteria for each intended use.
Why not place frozen gel packs directly against medicine cartons?
Direct contact can create a local cold point even while another part of the payload is warming. Conditioned coolant, a defined buffer and a fixed layout help manage this risk.
Should we use water-based gel packs or PCM?
That depends on the target range, allowed low limit, route profile, conditioning process and cost. Compare candidates with the actual payload and a defined sensor map.
Where should temperature loggers be placed?
Development work commonly examines likely warm, cold and representative payload locations. The final shipment monitoring position should follow the approved protocol and quality procedure.
Can Tempk supply a reusable pharmaceutical cooler?
Yes. An EPP or other reusable format can include removable PCM panels, tamper points, labels and operating instructions. The return, cleaning and inspection process should be defined at the same time.
What information is needed for a thermal test?
Provide product limits, payload dimensions and mass, starting condition, route duration, seasonal ambient profile, delay allowance, shipper constraints, coolant conditioning and acceptance criteria.
Does a 2–8°C label guarantee a shipping duration?
No. Ask for a report matching the packout, payload, starting conditions and ambient profile. This page does not establish a universal shipping duration or a qualified configuration.
