Shipping temp-sensitive cargo? EPP (Expanded Polypropylene) thermo boxes act like armor against temperature swings. Think of them as tiny, ultra-efficient coolers for vaccines, fresh food, and lab specimens that can’t afford to warm up.

Why Every Cold Chain Needs EPP Boxes
A single degree of temperature drift can ruin medicines or spoil produce. EPP boxes trap cold air like a thermos – their foam walls create a stable microclimate even in hot trucks or delayed flights.

Tempk’s EPP Boxes: Precision Cooling Made Simple
We engineer EPP boxes that actually solve logistics headaches:
Validated performance: 48hr stability at -20°C (IV drugs) to +25°C (chocolates)
Plug-and-play: Works with gel packs, dry ice, or PCM panels
Pharma-ready: Cleanroom compatible surfaces
Custom sizing: Snug fits for vials, produce crates, or bulk pharma
Stop Temperature Emergencies Before They Start
Tempk EPP boxes don’t just ship goods – they prevent costly spoilage. One reusable box can safely deliver:
• Vaccines staying at 2-8°C
• Frozen seafood at -18°C
• Chemistry reagents requiring 15-25°C
Cold Chain Pro Tip: Combine EPP boxes with Tempk’s GPS loggers for real-time temperature monitoring – eliminate guessing games.
