Picking the wrong thermocol box size wastes money and risks thawed goods. Here’s a practical guide to our two standard sizes.
Thermocol Box 3kg — Best For
- Small frozen food deliveries and tiffin services
- 2–3kg of dry ice for samples, medicines, or lab transport
- Ice cream cakes and desserts for events
- Gifting frozen items across Karachi
Thermocol Box 5kg — Best For
- Seafood and meat shipments (5–8kg of product with ice)
- 4–5kg of dry ice for full-day cooling
- Restaurant and caterer bulk deliveries
- Exporters packing frozen cartons
The Golden Rule
Choose the smallest box that fits your goods. Empty air space makes dry ice sublimate faster and wastes cooling. When in doubt between sizes, go smaller and pack gaps tightly.
Pairing With Dry Ice
Thermocol boxes and dry ice are made for each other — the box’s insulation can stretch 16mm pellets to a full 24–48 hours of −78.5°C cold. Read our dry ice guide →
