Pure water cold packs, sealed in food-grade film and flat on arrival. We help you qualify the pack-out for the range it must hold and work with your QA team on the records you need.








Each therapy has its own range, so each program needs its own pack-out qualification.
Cleanliness is the first question pharmacy teams ask about coolant. Ours starts with what is inside.
Front
Side, as deliveredNo gels, additives or dyes next to the medication.
Puncture-resistant film with a heat-sealed edge.
Flat is built into how we make them, so every pack arrives flat for a consistent fit in your shipper.
Packs come stacked straight on the pallet, with no cartons to open and fewer touchpoints before the pack bench.

A patient drains the pack and follows local waste management guidelines for the film, instead of wondering what to do with gel. It is a better unboxing for someone receiving medication, and a lighter Extended Producer Responsibility (EPR) burden for you.
Same weight of coolant, same insulated shipper, same 72-hour ambient profile, tested at an independent lab accredited to ISO/IEC 17025:2017. It shows how water performs against gel. Your own pack-out is qualified separately.
A conventional cold pack passes through several trucks and freezer warehouses, often run by different operators, before it reaches your pack-out. Our RELO microfactory makes frozen packs on site, so they skip those handoffs and supply never waits on a freezer truck.
The RELO microfactory sits inside or right outside your fulfillment center and runs on water and power. It makes frozen packs to your spec and stacks them on the pallet with no cartons, ready at its loading dock for your pack-out station.
No equipment to buy, no one to hire and nothing to maintain. Your part comes down to two things.

Cold pack production uses the same on-site model.

Fit water cold packs to your payload, lanes, and limits on box size, weight and coolant.
Test the pack-out under defined conditions. ISTA shipping protocols, ASTM mechanical testing or a 2–8 °C climatic chamber are available on request.
