If you’re searching for dry ice packs at Walmart, here’s the short answer: you’ll mostly find reusable “dry ice” style freezer packs (phasechange packs) online and in stores, while actual dry ice (solid CO₂) is available only at select locations—call ahead or use a dry ice locator to confirm. Reusable packs at Walmart include Arctic Ice Tundra/Chillin’ Brew, Techni Ice, and similar brands with clearly listed freezing points for predictable hold time. (Walmart.com)

What does “dry ice packs at Walmart” actually mean?
Most “dry ice packs at Walmart” are not literal dry ice—they’re reusable phasechange packs meant to hold colderthanice temperatures without the hazards of solid CO₂. The popular Arctic Ice Tundra Series freezes at about 5 °F (−15 °C) to keep contents near freezer temps; Chillin’ Brew targets about 28 °F (−2 °C) for drink/beverage cold. Techni Ice offers sheetstyle packs you hydrate, freeze, and cut to size for liners or wraps. These are the items you can reliably order online or find in many stores. (Walmart.com)
What about actual dry ice? Availability varies by location. Some large grocers (and some Walmarts) carry Penguin Brand or other dry ice in a locked cooler; not every store has it, and it’s rarely sold for home delivery. Use a dryice locator or call your store before you drive. (The Takeout, Penguin Brand Dry Ice®)
Which dry ice packs at Walmart keep food frozen longest?
Shortlist by freezing point and mass. Lower freezing point + higher pack weight usually equals longer hold time (assuming an insulated cooler and prechilled contents).
Arctic Ice Tundra Series — PCM setpoint ~5 °F; sizes from 0.75 lb to 10 lb; designed to keep items frozen in a cooler. (Walmart.com)
Arctic Ice Chillin’ Brew — setpoint ~28 °F; tuned for beverages and fridgecold perishables. (Walmart.com)
Techni Ice HDR/Standard sheets — sheetbased packs you hydrate and freeze; flexible, easy to line coolers or shipper walls. (Walmart.com)
Thermafreeze Cryosheet — cellular sheets you hydrate and freeze; handy for lunch totes or small shippers. (Walmart.com)
Thirdparty field tests continue to rank Arctic Ice and Cooler Shock among top performers for hold time (modeldependent), with recent 2025 tests giving gelbased packs an edge for multiday cold retention (size and prechill matter). (Serious Eats)
Freezing point vs. job to be done
| Use case | Best setpoint | Walmart examples | ماذا يعني بالنسبة لك |
|---|---|---|---|
| Keep meat frozen | ~5 °F (−15 °C) | Arctic Ice Tundra (0.75-10 رطل) | Maintains “freezerlike” temp; combine multiple panels for multiday trips. (Walmart.com) |
| Keep drinks colder than ice water | ~28 °F (−2 °C) | Arctic Ice Chillin’ Brew | Keeps beverages extra crisp without freezing solid. (Walmart.com) |
| Line a lunch bag / wrap items | Variable | Techni Ice sheets; Thermafreeze | Conformable; cut to fit; great as gapfillers for small shipments. (Walmart.com) |
Pro tips for longer hold time
Prechill packs (24–36 hours for lowsetpoint packs like Tundra) and precool your cooler. Tundra’s low setpoint takes longer to solidify. (Walmart.com)
Use mass smartly: several smaller panels increase contact area and improve heat pickup vs. a single big block—especially around oddly shaped foods. (This is why sheetstyle packs shine for meal kits.)
Layering: cold packs at top and bottom, with perishables sandwiched, limits warm air infiltration when you open the lid. External guides echo these habits for best results. (Epicurious, Real Simple)
How many dry ice packs at Walmart do you need?
Use this quick estimator for a hardsided cooler packed tight with prechilled food (mostly frozen), stable ambient 86 °F/30 °C, and minimal lid openings:
Day trips (≤12 hours): ~10–15% of cooler volume in packs.
1–2 days: ~20–30% of cooler volume in packs.
2–3 days: ~30–40% of cooler volume in packs (favor lower setpoint, e.g., Tundra).
Example: A 45qt (~42.6 L) cooler for a 36hour run might use four 2.5lb Tundra panels (≈10 lb total), split top/bottom with one side panel. Adjust up if you’ll open the lid often or ambient temps exceed 95 °F.
| Cooler size | 12 ح (mixed foods) | 24–36 h (frozen focus) | 48–60 h (frozen focus) | What to buy at Walmart |
|---|---|---|---|---|
| 24–30 qt | 2 × 1.5 lb | 2 × 2.5 lb | 3–4 × 2.5 lb | Chillin’ Brew or Tundra, medium/large. (Walmart.com) |
| 45–55 qt | 2 × 2.5 lb | 3–4 × 2.5 lb | 4 × 2.5 lb + 1 liner | Tundra large + Techni Ice sheet liner. (Walmart.com) |
| 65–85 qt | 3 × 2.5 lb | 4–5 × 2.5 lb | 2 × 5 lb + liners | Tundra XL/10 lb + Techni Ice sheets. (Walmart.com) |
These are practical starting points, not lab specs. Pack weight, cooler quality, headspace, and how often you open the lid can double or halve performance. Thirdparty tests in 2025 still show pack size and prechill as the biggest wins. (Serious Eats)

Are dry ice packs at Walmart the same as real dry ice?
لا. Packs like Tundra or Techni Ice are reusable PCMs that behave like “dryice style” solutions—cold and tidy—but they aren’t solid CO₂. Real dry ice (UN1845) is colder (−109 °F / −78.5 °C), sublimates to CO₂ gas, and requires ventilation/PPE. Some Walmart locations may sell dry ice (often near the front in a locked merchandiser), but availability is storespecific; use a locator or call ahead. (Wikipedia, The Takeout, Penguin Brand Dry Ice®)
Locator tip: Penguin Brand Dry Ice maintains a U.S. store finder for nearby retailers carrying their product—handy if your local Walmart doesn’t stock it. (Penguin Brand Dry Ice®)
Dry ice packs at Walmart: أمان & التعامل مع (and when to use PPE)
Whether you choose reusable packs or real dry ice, play it safe.
CO₂ exposure limits: NIOSH/OSHA put CO₂ limits at 5,000 ppm TWA and 30,000 ppm STEL; avoid sealed spaces when sublimating dry ice. (مركز السيطرة على الأمراض)
Ventilation & حاويات: Never store dry ice in an airtight container—pressure can build and rupture. Keep it in a ventilated cooler. (ehs.ucsc.edu)
معدات الوقاية الشخصية: Use insulated/cryogenic gloves and eye protection when handling dry ice to prevent frostbite. OSHA’s quick guides echo these basics for labs and facilities. (إدارة السلامة والصحة المهنية)
Gas volume awareness: ~1 lb of dry ice releases roughly 250 L of CO₂—plan for airflow in cars and small rooms. (International Brotherhood of Teamsters)
Reusable packs: No sublimation risk, but follow label guidance: freeze time (often 24–36 h for lowsetpoint packs like Tundra) and don’t microwave. Walmart product pages list setpoints and sizes so you can choose correctly. (Walmart.com)
Buying dry ice packs at Walmart online vs. instore
Know the seller. On Walmart.com, you’ll see “Sold & shipped by Walmart” or Marketplace seller. Marketplace items can have different return windows and policies. Read the seller page and the return policy before you buy, especially for bulk packs. (Walmart.com)
Standard returns: Walmart generally offers 90day returns for many categories, with seasonal extensions around the holidays; Marketplace sellers may differ. Start an online return from your order history to generate a label. (Walmart.com, MySA)
Instock reality: Product availability and pricing vary by store and region. Check the store selector on Walmart.com for your ZIP, or consider Walmart Business if you’re buying for a workplace. (Walmart Business)
