Why Temperature Control Matters
When shipping vaccines, seafood, or fresh meals:
• One degree too warm = spoiled goods
• Temperature swings = failed deliveries
• Ice melts too fast in summer heat
That’s where freezer blocks (ice bricks) save the day – they’re the steady cold keepers for sensitive cargo.
How Freezer Blocks Work
Think of them as thermal batteries:
-
Freeze solid (-18°C or custom temps)
-
Absorb heat during transit (slower than ice)
-
Hold temperature 2-5x longer than gel packs
No messy leaks – just reliable cooling in:
• Insulated boxes
• Medical shippers
• Food delivery bags
