Solid carbon dioxide (CO₂) is an essential cryogenic cooling medium that sublimates directly from solid to gas at −78.5°C (−109.3°F). Unlike conventional water ice, dry ice produces no liquid residue, eliminating moisture damage during cold chain shipping and frozen food preservation.

Frequently asked questions
What is dry ice?+
Dry ice is solid carbon dioxide (CO₂). At normal atmospheric pressure it is about −78.5°C and sublimates directly from solid to gas instead of melting into liquid water.
Can I touch dry ice with bare hands?+
No. Direct contact can cause a severe cold burn or frostbite. Use insulated gloves or suitable tongs when handling dry ice.
Can dry ice be stored in an airtight container?+
No. Dry ice releases carbon dioxide gas as it sublimates, so airtight storage can create dangerous pressure. Use insulated packaging that allows gas to vent safely.
Which retail dry ice pack sizes are available?+
Dry Ice Pakistan offers standard 2kg, 5kg and 10kg retail packs, subject to current stock and delivery or pickup confirmation.
What pellet size is normally supplied for retail cooling?+
Standard retail cooling orders normally use approximately 16mm dry ice pellets. Specialist 3mm pellets are handled separately for industrial requirements.
How should unused dry ice be disposed of?+
Allow it to sublimate naturally in a secure, well-ventilated area away from children and pets. Do not seal it in a container or place it down a drain.
⚠️ SAFETY REMINDER (−78.5°C)
Always wear insulated gloves when handling dry ice. Ensure active ventilation, never store in airtight containers, keep away from children, and never ingest. Read our full Safety & Handling Guide.
