Dry Ice Packs Coles (2025): The Definitive Buyer & Guide d'expédition

What “dry ice packs Coles” really means in 2025

• In‑store reality: Coles lists gel/ice bricks and slim “ice walls”—handy for lunchboxes and small coolers—not solid CO₂. Exemple: Smash Gel Ice 3‑pack.

• Where to buy real dry ice: For CO₂ (−78.5 °C) choose BOC ICEBITZZZ™ pellets/boxes or Supagas blocks/pellets.

• Why the mix‑up: Shoppers often use “dry ice pack” to mean any cold brick; supermarkets stock gel/PCM, alors que CO₂ dry ice is a regulated refrigerant. Dry ice’s sublimation point is ~−78.5 °C.

Editor’s note for your team: this section aligns with—and replaces overlapping passages across your three drafts to avoid duplication and keyword stuffing.

Choose the right refrigerant (quick picker)

• Picnics & grocery runs: Retail gel bricks from Coles, Bunnings, etc.. → simple, réutilisable, low hazard.

• 2–8 °C lanes (kits de repas, Pharma): Utiliser +5 °C PCM for narrow‑band control (less freeze damage risk than 0 °C gels).

• Frozen or long‑haul: Utiliser −16 °C PCM ou CO₂ dry ice (ultra‑cold, no meltwater). Always provide venting and PPE.

Why +5 °C PCM > standard gel for 2–8 °C: WHO guidance and vendor specs show PCMs can be formulated to change phase right around 5 °C, keeping payloads in range more reliably than 0 °C gel packs.

Gel/PCM vs. CO₂ dry ice — at a glance

For consumer cooler use, recent testing shows gel designs often outperform plain water blocks for hold time, while hard bricks win for durability.

Sizing calculator (copy‑paste ready)

Exemple (day trip): 28 L cooler for 24 h, tightly packed → (28/3.5) × 1 × 1.0 ≈ 8 “mini bricks” or 2–3 medium hard bricks.
Exemple (frozen 36 h): 35 L shipper → (35/3.5) × 1.5 × 1.0 ≈ 15 minis; substitute 3–4 low‑freeze PCMs + side sheets.
This calculator carries over from your internal draft; I’ve standardized notation and added examples for clarity.

Dry ice rule‑of‑thumb (frozen): ~5–10 kg per 24 h per 30–40 L at room temp; blocks last longer than pellets. Always validate with your insulation and opening profile.

15‑minute pack‑out (works for Coles gel, Tempk PCM, or dry ice)

1. Precondition: Freeze gels solid; condition PCM to its setpoint; bag dry ice with paper to reduce flash‑freezing. WHO recognizes gels, PCMs and dry ice as valid coolants in passive systems.

2. Line & layer: Reflective liner → bottom layer of packs → payload centered with small side gap → top layer of packs.

3. Vent & verify (glace carbonique): Ensure a vent path—never airtight. Label “Dry Ice/UN1845” avec net kg.

4. Record start time and ambient; use a probe/indicator when possible.
   These steps harmonize the strongest how‑to elements across your three drafts.

Flying with dry ice in 2025 (Australia & beyond)

• Global baseline (IATA 66th/2025): Up to 2.5 kg per passenger, package must vent CO₂, and checked baggage must be marked Dry ice/Carbon dioxide, solid avec net weight (or “≤ 2.5 kg”).

• Airline examples: Qantas & Virgin show 2.5 kg limits and venting/marking in their public pages; Jetstar materials show the same limit in DG lists. Always declare at check‑in.

Sécurité 101 (print for the packing bench)

• EPP: Insulated cryogenic gloves + eye protection; avoid bare‑hand contact.

• Ventilation: Work in a well‑ventilated area; never store in airtight containers (pressure/oxygen risk).

• Food safety basics: Keep cold food ≤ 5 °C, chaud ≥ 60 °C; apply the 2‑hour/4‑hour rule for brief hand‑offs outside refrigeration (FSANZ, May 22 2025).

Where to actually buy in Australia (2025)

• Supermarket bricks (everyday): Coles listings (Par exemple, Smash® Gel Ice 3‑pack; Willow® bricks) for day use.

• Dry ice (frozen lanes): BOC ICEBITZZZ™ (pellets/boxes) et Supagas (blocks/pellets/slices). Check lead time and pellet diameter.

Why businesses graduate from “dry ice packs Coles” to Tempk

Rotation is engineered for validated, repeatable cold‑chain results: precise PCM setpoints (−16 °C / −5 °C / +5 °C), lane‑based pack plans, and documentation aligned with Iata 2025 acceptance checks—so you reduce excursions and pass airline acceptance first‑time. This positioning merges your drafts’ value props into a single buyer‑focused section.

FAQ

Q1: Does Coles sell “real” dry ice?
Non. You’ll mostly find gel bricks/ice walls at Coles. For solid CO₂, use BOC or Supagas.

Q2: What should I use for 2–8 °C shipments?
Utiliser +5 °C PCM rather than 0 °C gel to avoid accidental freezing and hold a tight band.

Q3: Can I fly with dry ice?
Yes—2.5 kg per passenger, vented packaging, declared at check‑in, and marked with UN1845 + net kg.

Q4: Do gel packs last as long as dry ice?
Non. Dry ice is far colder (−78.5 °C). That said, controlled tests show gel designs are excellent for coolers when pre‑chilled
