Which retailers carry dry ice packs near you?
Short answer: For small, same‑day needs, check local supermarkets; for larger or recurring orders, go to specialty gas suppliers; for shipping‑friendly convenience, consider reusable PCM “dry ice” packs online. You’ll get predictable availability, better sizing, and fewer surprises at the counter.
Why this matters to you: Grocery stores are convenient but seasonal; some locations only stock during peaks like summer or Halloween. Specialty suppliers keep year‑round inventory, offer blocks or pellets, and give safety tips at pickup. Reusable phase‑change packs ship legally and store at home—great when dry ice packs aren’t practical for air transport or apartment storage.
How to confirm store availability for dry ice packs
Call first, then plan pickup. Ask the service desk if they stock today, the typical pack size (often 1–10 lb blocks), and whether they limit quantities. For specialty suppliers, request pellets (easier packing) or cut blocks. Bring an insulated cooler, leave the lid vented, and use gloves. If stock is tight, pivot to reusable PCM packs for equivalent sub‑zero performance.
| Source type | Typical availability | Common formats | What it means for you |
|---|---|---|---|
| Supermarkets | Seasonal / location‑dependent | 1–10 lb blocks | Easy same‑day buys; call ahead |
| Big‑box clubs | Seasonal bulk | ~10 lb blocks | Good per‑pound price; membership needed |
| Specialty gas suppliers | Year‑round | Blocks, pellets, slabs | Reliable supply + safety guidance |
| Reusable PCM packs (online) | Year‑round | -20°C to -26°C packs | Ship legally; safer handling at home |
Practical tips and quick wins
-
Short errand: Buy 5–10 lb for a day trip; vent the cooler and separate food with cardboard.
-
Overnight parcel: Choose pellets and pack around the product; note the net dry ice packs weight on your label if required.
-
Apartment living: Store reusable PCM bricks in your freezer; no gas, no hazmat, repeat use.
Real case: A bakery needed to ship pies overnight statewide. They used ten 2‑lb blocks of dry ice packs in a vented cooler. Result: pies arrived fully frozen; packaging cost under $5 per pie, and handling stayed simple for staff.
How many dry ice packs do you need for shipping or travel?
Rule of thumb: Plan ~10 lb of dry ice packs per 24 hours for a 24–30 qt cooler; double for 48 hours or frequent openings. Blocks last longer; pellets fill gaps and cool evenly.
Details that help you decide: What matters most is container insulation, outside temperature, product mass, and how often you open the lid. If your route or hold time is uncertain, add a 20–30% buffer. For food contact, keep a layer (cardboard/newspaper) between product and dry ice packs to avoid freezer burn.
Packing dry ice packs the smart way
Layering and venting: Put a thin insulating layer below and above product; place pellets around the sides; keep the lid slightly vented so CO₂ can escape. Never use an airtight container—pressure can build. Wear insulated gloves; at −109.3°F (−78.5°C), bare‑skin contact can injure in seconds.
| Situation | Cooler size | Hours needed | Recommended amount | Why it works |
|---|---|---|---|---|
| Farmers’ market day | 24 qt | 8–12 h | 5–6 lb pellets | Even cooling; frequent lid opens |
| Overnight courier | 30 qt | 24 h | ~10 lb mixed | Blocks + pellets extend hold time |
| 48‑h road trip | 45 qt | 48 h | 20–25 lb blocks | Lower surface area; slower loss |
Are reusable “dry ice” PCM packs better for your use?
Short answer: If you need safer handling, standard shipping, and repeat use, reusable PCM dry ice packs are often the better choice; if you need −78.5°C extremes, stick with solid CO₂. PCMs hold −20°C to −26°C steadily—ideal for food, diagnostics, and day‑to‑day shipping.
What this means: PCMs avoid hazmat rules, ship ground or air without special labels, and recharge in a freezer. Solid CO₂ reaches much colder temps but requires ventilation, gloves, and age limits in some regions. Many shippers blend both: dry ice packs for deep‑freeze, PCM bricks for steady maintenance.
Quick comparison you can act on
| Feature | Dry ice (CO₂) | Reusable PCM “dry ice packs” | Your takeaway |
|---|---|---|---|
| Temperature | ~−78.5°C | −20°C to −26°C | Choose based on product needs |
| Safety | Hazmat; venting required | Non‑hazmat; easy handling | PCMs are user‑friendly |
| Duration | Fast sublimation | Stable hold | PCMs reduce spikes |
| Cost | Low per lb, single use | Higher upfront, reusable | Frequent users save with PCMs |
Actionable tips
-
Weekend shipper: Use PCM bricks to avoid airline hazmat limits and reuse weekly.
-
Lab samples at −20°C: Pre‑condition −21°C plates in a blast freezer; log temperature on arrival.
-
Ice cream events: Combine a base of dry ice packs blocks with PCM lids to smooth temperature swings.
Safe handling: the habits that prevent accidents with dry ice packs
Core practices: Use gloves/tongs, ventilate containers, and never seal CO₂ in an airtight box. Keep children and pets away. Allow leftover dry ice packs to sublimate in a ventilated area; do not trash or sink them.
Why it’s simple: CO₂ gas displaces oxygen; ventilation stops pressure buildup and keeps you safe. Insulated—but not airtight—coolers are your friend. Label parcels with net dry ice packs weight if required by your carrier or lane.
2025 developments and trends for dry ice packs
What’s new in 2025: Sustainability and sensors lead the way. Recyclable insulation and returnable PCM systems cut waste, while low‑cost Bluetooth loggers show live temperature and location. Many SMEs add on‑demand pelletizers to avoid delivery bottlenecks and stabilize supply when demand spikes.

Market insight: Direct‑to‑consumer groceries, specialty desserts, and diagnostics continue to grow, pushing mixed systems that pair dry ice packs for deep‑freeze segments with PCM bricks for last‑mile stability.
Frequently Asked Questions
Q1: Where is the most reliable place to buy dry ice packs?
For small amounts, check nearby supermarkets; for bulk or repeat needs, use specialty gas suppliers. Reusable PCM dry ice packs online are best for non‑hazmat shipping.
Q2: How much dry ice do I need for a 30‑qt cooler?
About 10 lb for 24 hours. Double that for 48 hours or heavy opening.
Q3: Can I ship dry ice packs by air?
Yes, but follow carrier rules: vented packaging and net weight labeling for CO₂. PCM packs ship as non‑hazmat.
Q4: Are reusable PCM “dry ice” packs as cold as real dry ice?
No. They hold −20°C to −26°C steadily, which covers most food and many medical needs without CO₂ risks.
Q5: What safety gear do I need?
Insulated gloves or tongs and eye protection when breaking blocks. Vent containers to release gas.
Summary & Recommendations
Three takeaways: 1) Choose source by need—supermarket, supplier, or PCM online. 2) Size your dry ice packs with simple rules (~10 lb/24 h for 24–30 qt). 3) Handle with ventilation and gloves. Use the calculator above before you buy, and consider reusable PCM bricks if you ship often.
Next steps: Decide your hold time, pick blocks vs. pellets, and reserve pickup. For repeat shipments, trial a PCM kit alongside dry ice packs and add a low‑cost sensor. Ready to optimize? Contact Tempk for a tailored cold‑chain plan and sample kit.
