When a shipment of fresh salmon or life-saving vaccines travels hundreds of miles, one thing matters most: keeping them at the right temperature. Entrer ice pack bricks—rugged, reusable blocks designed to deliver steady, reliable cooling from start to finish. Unlike flexible gel packs that shift with the ride, these rigid bricks use smart science to maintain a consistent “cold zone,” making them a game-changer for food, Pharma, and logistics teams alike.
What Are Ice Pack Bricks, and How Do They Work?
Ice pack bricks are like portable “cooling batteries.” They’re rigid, food-grade plastic shells (often high-density polyethylene) filled with a special cooling gel or phase-change material (PCM). When frozen, this gel absorbs heat slowly and steadily, releasing it over hours or even days to keep cargo cold.
The magic lies in their rigid design: no sagging, no leaking, and no messy ice crystals. This stability ensures your cargo stays within a tight temperature range—even during long hauls or unexpected delays.
Why Ice Pack Bricks Beat Flexible Packs for Cold Chain Reliability
1. Consistent Cooling, No Surprises
Flexible gel packs conform to cargo but can shift, creating hot spots. Briques de glace, with their solid shape, distribute cold evenly. This means:
- Food stays crisp: Salad greens remain fresh for 48+ heures, even on hot days.
- Medicines stay potent: Vaccines and biologics maintain their 2–8°C range without temperature spikes.
2. Logistics-Friendly Design
Bricks stack neatly, reducing empty space in shipments and preventing product damage. Warehouses love them too—they freeze faster (thanks to high-velocity fans) and last thousands of trips, cutting waste and costs.
3. Sustainable & Cost-Effective
Modern ice bricks use non-toxic, biodegradable PCMs and recyclable shells. Reusing them slashes single-use plastic waste, while their long lifespan lowers long-term costs for businesses.
Choosing the Right Ice Pack Brick
To get the best results, match the brick to your cargo:
- Temperature needs: A 0°C brick works for ice cream; a +5°C brick suits tropical biologics.
- Size matters: Use slim bricks for small orders or power bricks for bulk shipments.
- Certifications: Look for FDA-approved (non-toxic) and ISTA-tested (reliable for shipping) options.
Why Tempk Ice Pack Bricks Stand Out
Tempk’s bricks take reliability to the next level with features built for real-world logistics:
1. Tougher Than Ever
Their food-grade HDPE shell is 30% thicker than standard, shrugging off drops, forklift bumps, and rough handling. No leaks, no ruptures—just steady cooling.
2. Longer-Lasting Cold
Tempk’s proprietary PCM holds 15% more cooling power, keeping cargo cold for 72+ hours in 30°C heat. That’s enough for cross-country deliveries or last-mile runs.
3. Custom Fit for Your Business
Need a unique size, couleur, or branding? Tempk lets you customize shells and add laser-etched IDs for inventory tracking. Plus, modular designs let you swap sizes without redesigning packs.
4. Eco-Conscious by Design
Reusable shells reduce plastic waste by 70% over single-use packs. Some models even use bio-based PCMs, turning waste into value at end-of-life.
Final Thoughts
In the cold chain, consistency is king. Ice pack bricks deliver that consistency—no matter the cargo, route, or weather. With Tempk’s tough, precise, and sustainable design, you’re not just keeping things cold—you’re keeping them frais, sûr, et profitable.
Because when perishables arrive as intended, everyone wins.
