La glace sèche emballe les coles (2025): L'acheteur définitif & Guide d'expédition
Quoi "dry ice packs Coles” really means in 2025
-
Réalité dans les étages: Coles lists gel/ice bricks and slim “ice walls”—handy for lunchboxes and small coolers—not solid CO₂. Exemple: Smash Gel Ice 3-Pack.
-
Où acheter de la vraie glace sèche: Pour co₂ (−78,5 ° C) choisir BOC ICEBITZZZ™ pellets/boxes or Supagas blocks/pellets.
-
Pourquoi le mélange: Les acheteurs utilisent souvent un «pack de glace sec» pour signifier toute brique froide; supermarkets stock gel / pcm, alors que CO₂ ICLE SEC is a regulated refrigerant. Dry ice’s sublimation point is ~−78,5 ° C.
Note de l'éditeur pour votre équipe: Cette section s'aligne sur - et remplace les passages qui se chevauchent dans vos trois brouillons pour éviter la duplication et la farce des mots clés.
Choisissez le bon réfrigérant (cueilleur rapide)
-
Pique-nique & Épicerie: Vente au détail Briques en gel from Coles, Bunnings, etc.. → Simple, réutilisable, danger faible.
-
2–8 ° C Lanes (kits de repas, Pharma): Utiliser +5 ° C PCM for narrow‑band control (Moins de risque de dommages-intérêts que les gels 0 ° C).
-
Gelé ou long: Utiliser −16 °C PCM ou CO₂ ICLE SEC (ultra-froid, pas d'eau de fonte). Always provide ventilation et EPI.
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
| Option | Typical source | Working temp | Pros | Watch-bots |
|---|---|---|---|---|
| Coles gel/ice bricks | Supermarchés | ~0 to 10 °C | Bon marché, réutilisable, facile | Shorter runtime for frozen lanes |
| Panneaux PCM +5°C | Specialists | Conserve ~5°C | 2–8 °C stability; moins de risque de gel | Must be preconditioned correctly |
| PCM −16 °C bricks | Specialists | ≤ −10 °C corridors | Frozen holds without DG paperwork | Needs validated pack plan |
| CO₂ ICLE SEC | BOC / Supagas | −78,5 ° C | Long frozen runtime, pas d'eau de fonte | Vented pack, label/limits, EPP |
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 (prêt à copier-coller)
Exemple (day trip): 28 L cooler for 24 h, bien emballé → (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 + feuilles latérales.
This calculator carries over from your internal draft; I’ve standardized notation and added examples for clarity.
Dry ice rule‑of‑thumb (congelé): ~5–10 kg per 24 h per 30–40 L at room temp; Les blocs durent plus longtemps que les pastilles. Always validate with your insulation and opening profile.
15‑minute pack‑out (works for Coles gel, Tempk PCM, ou glace sèche)
-
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.
-
Doubler & couche: Reflective liner → bottom layer of packs → payload centered with small side gap → top layer of packs.
-
Secouer & vérifier (glace carbonique): Ensure a chemin de ventilation- jamais hermétique. Étiquette “Dry Ice/UN1845” avec Kg net.
-
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 (Australie & au-delà)
-
Global baseline (IATA 66th/2025): Jusqu'à 2.5 kg per passenger, Package doit vent CO₂, and checked baggage must be marked Glace sèche / dioxyde de carbone, solide avec poids net (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: Isolé gants cryogéniques + protection des yeux; éviter le contact à mains nues.
-
Ventilation: Work in a ventilé zone; never store in airtight containers (pressure/oxygen risk).
-
Food safety basics: Keep cold food ≤ 5 °C, chaud ≥ 60 °C; appliquer le 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.
-
Glace sèche (voies gelées): 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 validé, repeatable cold‑chain results: précis Points de consigne PCM (−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: Puis-je voler avec de la neige carbonique?
Oui-2.5 kg per passenger, emballage ventilé, declared at check‑in, and marked with UN1845 + Kg net.
Q4: Do gel packs last as long as dry ice?
Non. Dry ice is far colder (−78,5 ° C). Qui dit, controlled tests show gel designs are excellent for glacières when pre‑chilled
