Buyer decision guide
What pharmaceutical buyers need from a cold chain packaging supplier
Pharmaceutical cold chain packaging should be selected as a complete packout, not by box or ice-pack name alone. Buyers usually need a supplier that can discuss target temperature, payload, transit duration, ambient profile, freeze risk, packaging format and documentation before recommending a product.
Match high-value payloads
Use payload mass, transit time and lane seasonality to compare gel packs, PCM packs, EPP boxes and VIP medical cool boxes.
Support sample movement
Build practical packaging options for diagnostic kits, reagents, lab samples and decentralized clinical-trial shipments.
Control longer routes
Review 48h, 72h and longer passive solutions when shipments pass through customs, air cargo, regional warehouses or multiple handovers.
Always check the product label claim, storage instruction and your internal QA/SOP before choosing a packaging format. Tempk can support packaging selection, but the final commercial packout should fit your GDP/GxP process, lane qualification plan and release criteria.
Temperature range planning
Choose pharmaceutical packaging by temperature range and hold time
Use this table to turn a shipment requirement into a practical packaging discussion. Start with the required product temperature, then confirm hold time, payload mass, ambient exposure and testing plan.

System design
Build a complete passive temperature-controlled packaging system
For pharma logistics, the shipper, coolant and packing method work together. Treat the packaging as a repeatable system, so every shipment can be loaded, monitored and reviewed in the same way.
Cooling media
Gel ice packs, PCM packs and ice bricks supply thermal energy for refrigerated, CRT or frozen routes. Conditioning temperature, pack quantity and placement must be controlled.
Insulated shipper
EPP cooler boxes, VIP medical cool boxes, plastic insulated boxes and insulated cartons create the thermal barrier around the payload.
Payload separation
Buffers, liners and separators help prevent direct coolant contact and reduce cold spots around freeze-sensitive products.
Monitoring
Temperature loggers or monitors help review shipment performance, investigate excursions and support internal quality records.
Packout instruction
A repeatable packing instruction should define coolant conditioning, loading sequence, payload placement, logger position, closure method and maximum open time.
Pallet protection
Thermal pallet covers help reduce heat gain or cold exposure during airport tarmac handling, warehouse transfer and line-haul freight.
Tempk product paths

Temperature hold examples
Published Tempk pharma temperature-hold examples for early selection
These examples from Tempk’s pharmaceutical shipment solution can help buyers understand possible temperature-control directions before requesting lane-specific testing or verification.
2–8°C / 48h high ambient —>50hMaintained 2–8°C under 36°C ambient test conditions.
2–8°C / 48h low ambient —>70hMaintained 2–8°C under −20°C ambient test conditions.
2–8°C / 72h high ambient —>77hMaintained 2–8°C under 35°C ambient test conditions.
2–8°C / 72h low ambient —>97hMaintained 2–8°C under −20°C ambient test conditions.
15–25°C high ambient —>115hMaintained 15–25°C under high ambient test conditions.
Ultra-low temperature —>72hMaintained around −70°C under 36°C ambient test conditions.
Treat these examples as early reference only. Test performance changes with shipper size, payload volume, coolant type, conditioning temperature, loading sequence, ambient profile and route duration. For commercial deployment, request a packout review and perform your own lane qualification or acceptance testing before bulk use.

Pharma packaging FAQ
Frequently asked questions
Practical answers for procurement, QA, logistics and packaging teams evaluating passive pharmaceutical cold chain packaging.
What is pharmaceutical cold chain packaging?
Pharmaceutical cold chain packaging is a temperature-controlled packaging system used to protect medicines, vaccines, biologics, diagnostics, reagents and lab samples during transport. A passive system usually combines an insulated shipper, cooling media, payload protection, temperature monitoring and a repeatable packing instruction.
What packaging is commonly used for 2–8°C pharmaceutical shipping?
A 2–8°C shipment often uses an EPP, VIP or insulated carton shipper with conditioned gel packs, PCM packs or ice bricks. Freeze-sensitive payloads may need separators or buffers to avoid direct contact with frozen coolant.
Should I choose gel packs or PCM packs for pharma shipments?
Gel packs are common for cost-effective refrigerated shipping. PCM packs are useful when the target temperature window is narrower or when more stable thermal behavior is needed. The right choice depends on product limits, payload mass, hold time, lane profile and conditioning process.
How long can passive pharmaceutical cold chain packaging hold temperature?
Passive packaging can be designed for 24h, 48h, 72h or longer, but actual hold time depends on shipper size, coolant quantity, payload mass, conditioning, ambient profile and handling. Use published examples only as a starting point; commercial deployment should be supported by testing or lane qualification.
Do pharmaceutical cold chain shipments need temperature loggers?
Temperature loggers or monitors are commonly used to document conditions, review excursions and support QA records. Logger placement should be defined in the packing instruction and checked during sample or lane testing.
What information should I send to Tempk before requesting a bulk quote?
Send target temperature range, allowed excursions, product dimensions, payload weight, units per shipper, route, transit duration, season, packaging format, reusable or single-use preference, sample or bulk quantity, MOQ expectation and OEM labeling needs.
Need a pharmaceutical cold chain packaging recommendation?
Share your target temperature, route, payload and transit duration. Tempk can help compare gel packs, PCM packs, EPP/VIP boxes, insulated liners, pallet covers and packout options before sample testing or bulk procurement.
