Common questions
How long do these cold bricks stay frozen?
Re-Freez-R-Brix bricks maintain freezing temperatures for over 12 days when properly pre-frozen and insulated, significantly outlasting standard ice packs or gel alternatives.
Are these compliant with pharmaceutical shipping regulations?
Yes. These bricks are formulated with food-safe, non-toxic materials and generate no liquid leakage, meeting FDA and IATA requirements for cold-chain shipments of pharmaceuticals, blood products, and lab samples.
Can I reuse these cold bricks?
Absolutely. Simply refreeze after each use. The heavy-duty plastic pouch withstands hundreds of freeze-thaw cycles, making them a cost-effective, long-term investment versus disposable alternatives.
What's the advantage over traditional ice or gel packs?
Unlike ice, these bricks won't melt into water and contaminate shipments. Unlike gel packs, they deliver 12+ days of consistent chilling, eliminate product damage risk, and reduce per-shipment costs over time through reusability and longer performance windows.
