Solid carbon dioxide (dry ice) sublimates at −78.5°C (−109.3°F) directly into clean CO₂ gas without producing liquid water moisture. This remarkable property makes dry ice an invaluable cooling agent across medical cold chains, food logistics, industrial maintenance, and event entertainment. Learn more about its fundamental properties in our guide to What is Dry Ice?.
1. Vaccine & Medical Supply Transportation
In healthcare logistics, maintaining ultra-low temperature integrity is critical for vaccines, biological specimens, tissue samples, and blood plasma. Dry ice absorbs thermal energy rapidly during transit, keeping medical shipments safely frozen without requiring active electrical refrigeration. For safety protocols during handling, review our Health & Safety Guidelines.
2. Food & Beverage Preservation
Dry ice is widely used for preserving perishable meats, fresh seafood, dairy, and ice cream during shipping and distribution. Because solid CO₂ sublimates into dry gas, shipping cartons and food products remain completely moisture-free. Explore commercial cooling options in our Dry Ice Applications Guide.
3. Industrial Cleaning and Dry Ice Blasting Applications
Dry Ice Pakistan supplies high-density 3mm dry ice pellets suitable for industrial blasting equipment. Blasting machines accelerate pellets at high velocity to remove grease, carbon buildup, and production residue from heavy machinery without chemical solvents or abrasive grit.
4. Fog & Smoke Effects for Events
Submerging dry ice in warm water produces a dense, ground-hugging white fog widely used for wedding entrances, stage theatrical performances, and film sets. Because cold CO₂ fog stays low to the floor, it creates dramatic visual effects without lingering airborne residue.
5. Temperature-Controlled Shipping
Commercial logistics providers rely on dry ice for cold-chain transport of high-value perishables, pharmaceuticals, and temperature-sensitive electronics across Pakistan. Estimate your required quantity using our Sublimation Calculator.
6. Laboratory Cooling & Storage
Scientific laboratories use solid CO₂ to maintain ultra-low thermal environments for chemical reactions, specimen freezing, and sample preservation where conventional electric freezers are unavailable or during power backup scenarios.
7. Frozen Food Production & Packaging
During food processing, dry ice is utilized for flash-freezing ingredients, maintaining dough temperatures during industrial mixing, and protecting frozen meals during final packaging and pallet shipping.
Which Dry Ice Pack Is Right for Your Requirement?
Dry Ice Pakistan supplies standard 16mm dry ice pellets in insulated retail and commercial packs, plus 3mm precision pellets for industrial applications. Larger legacy weight routes are handled as custom or bulk enquiries. Browse available sizes in Our Products Catalog.
Important Dry Ice Safety Considerations
// CRYOGENIC SAFETY RULES (−78.5°C)
- Wear Insulated Gloves: Never touch solid CO₂ with bare skin to prevent frostbite.
- Ensure Ventilation: Use dry ice only in well-ventilated areas to prevent CO₂ gas displacement.
- Never Seal Air-Tight: Dry ice sublimates into gas expanding ~800x; containers must allow gas venting.
- Keep Away from Children: Store securely out of reach of minors and pets.

Frequently Asked Questions
What are the most common uses of dry ice in Pakistan?
Vaccine transport, food preservation, ground fog effects for events, laboratory cooling, and 3mm industrial pellet blasting.
Does dry ice leave liquid water behind?
No. Dry ice sublimates directly from solid CO₂ into carbon dioxide gas, leaving zero liquid moisture.
How long does dry ice last in an insulated box?
Sublimation rate is typically 2kg to 5kg per 24 hours depending on insulation quality, ambient temperature, and box size.
Conclusion
From temperature-sensitive medical transportation to ground fog event effects and commercial food shipping, solid carbon dioxide provides an unbeatable cryogenic cooling solution across Pakistan. Always follow proper safety handling procedures, wear protective gloves, and choose the right pack size for your operational requirements.
