What is a dry ice pack 7×13, et quand faut-il l'utiliser?

A dry ice pack 7×13 is a vented 7×13-inch pouch you fill with dry-ice pellets, delivering −78.5 °C source cooling for frozen lanes. Use it when your payload must arrive fully frozen for 24–72 hours and you can follow hazmat marking and venting rules. It nests around corners, reduces air gaps, and fits small parcel coolers efficiently.

Why it’s useful for you: The format blankets small loads without heavy overpack. It produces no meltwater, keeps cartons dry, and simplifies acceptance when you mark UN1845 and show net kilograms. If your target band is 2–8 °C, consider PCM or a hybrid to avoid over-cooling sensitive goods.

Sizing rules of thumb for dry ice pack 7×13 loads

Commencer par ~1–1.5 lb (0.45–0.7 kg) de glace sèche par 24 h per 6–8 L of insulated volume, then scale for duration and season. Round up your final count because sublimation starts as soon as pellets are loaded. For hot routes, add 25–50% more than winter baselines.

Packout component impact	Qu'est-ce que c'est	Que vérifier	Ce que cela signifie pour vous
Dry-ice source	Solid CO₂ at −78.5 °C	Taille, fraîcheur	Predictable ultracold performance without liquid residue.
7×13 bag	Vented CO₂-safe pouch	Seam integrity, chemin de ventilation	Gas escapes; reduced rupture risk and easier air acceptance.
Expéditeur isolé	PSE, PPE, VIP, rigid coolers	Valeur R, pack serré	Lower sublimation and longer hold time for same mass.

Conseils et suggestions pratiques

Frozen food parcel: Prefreeze below −18 °C; top-blanket one dry ice pack 7×13 and place another along the warm wall.
Échantillons de laboratoire: Use secondary containment; position packs around racks, not directly on fragile vials.
Voies d'été: Upsize the dry ice pack 7×13 count by 25–50% and vent the lid path.

Cas réel: A dessert brand used two dry ice pack 7×13 units in a 10 L shipper for 2-day air during 32 ° C ambiant. Pints arrived rock-solid and cartons stayed dry because dry ice sublimates, not melts.

How many dry ice pack 7×13 units do you need for 24–72 hours?

Use a three-step calculator: estimation 24 h need from volume, scale by hours and lane factor, then convert kilograms to packs. This keeps sizing transparent and repeatable across teams. Keep packaging vented; US rules require CO₂ release.

Conseils élargis: Start with the volume-based baseline, multiply by time and a lane factor (1.0 cool, 1.25 moyenne, 1.5 chaud), then divide by your typical per-pack fill. Place one dry ice pack 7×13 at the highest heat-gain surface (usually the top) and another near the label side. Validate on real lanes with data loggers.

Exemple réel: A diagnostics shipper cut complaints by switching to two dry ice pack 7×13 plus a vented lid; logger traces confirmed 48-hour stability.

Compliance and safety for dry ice pack 7×13 dans 2025?

Do four things: emballage de ventilation, Appliquer la classe 9 étiquette, mark “UN1845” with net dry-ice kilograms, and follow IATA PI 954/49 CFR 173.217. Keep a copy of the 2025 acceptance checklist in your SOPs. For worker safety, use cryo-gloves, protection des yeux, and good ventilation.

Pourquoi ça compte pour toi: Vented design prevents pressure buildup, the UN1845 mark and net-kg figure speed air-carrier acceptance, and consistent labeling avoids returns. OSHA’s 8-hour CO₂ limit is 5,000 ppm; NIOSH lists IDLH at 40,000 ppm—training and monitors reduce risk in staging areas.

Labeling and documentation checklist

Vocation: Packaging must permit CO₂ release; never fully seal coolers.
Marquer: Imprimer UN1845 et poids net de glace carbonique (kg) sur la boîte extérieure.
Étiqueter: Appliquer la classe 9 étiquette de danger; place where visible after handling.
Document it: Show UN1845 and net kg on the air waybill when applicable.

Labeling element	Exigence	Common slip	Ce que cela signifie pour vous
UN1845 text	On outer package	Missing net kg	Delays or refusal at acceptance.
Classe 9 étiquette	Per IATA/Carrier	Wrong placement	Re-work and missed uplift.
Chemin de ventilation	“Must permit release”	Taped-shut lid	Rupture risk; non conforme.

Dry ice pack 7×13 vs gel and PCM—what fits your lane?

Pick a dry ice pack 7×13 for shipments that must arrive frozen; pick gel/PCM when you need 2–8 °C. Dry ice is ultracold and residue-free but requires hazmat marks; PCM targets narrow setpoints and eases air acceptance. Hybrids often win for mixed loads.

En pratique: Top-blanket a dry ice pack 7×13 to protect frozen SKUs, puis placez +5 °C PCM panels closer to sensitive items. This limits freeze risk, simplifies compliance, and can reduce total dry-ice mass on summer lanes. Validate both winter and summer profiles.

Decision guide: choose the right refrigerant

Frozen-only payloads: Favor dry ice pack 7×13 seulement; maximize insulation before adding mass.
Strict 2–8 °C corridors: Prefer PCM first; add minimal dry-ice buffer if needed.
Télédiques mixtes: Use a divider; combine PCM and dry ice pack 7×13 with a clear vent path.

2025 trends shaping dry ice pack 7×13 usage

Three shifts to plan for in 2025: tighter air-acceptance discipline around UN1845 net-kg marks; wider adoption of cellular/BLE data-loggers; and sustainability pressure that drives hybrid PCMs and higher-R shippers to lower dry-ice mass. The upshot is better monitoring, fewer acceptance errors, and lower cost per lane.

Dernier progrès en un coup d'œil

Operator caps: Some airlines require declaring net dry-ice mass at booking for aircraft-level limits.
Connected packouts: Off-the-shelf loggers simplify continuous monitoring and audit trails.
Higher-R packaging: VIP and molded EPP reduce sublimation for the same dry ice pack 7×13 compter.

Perspicacité du marché: Cold-chain demand keeps climbing with biologics and e-grocery. Expect more validation asks, more sensor data in QMS, and more emphasis on rightsized dry ice pack 7×13 mass per route and season.

Questions fréquemment posées

How long will a dry ice pack 7×13 dernier?
Plan for 24–72 hours depending on insulation, chaleur ambiante, and fill mass. Start with 1–1.5 lb per 24 h per 6–8 L and round up for hot lanes.

What labels are required when I use a dry ice pack 7×13?
Appliquer la classe 9 label and mark UN1845 with net dry-ice kilograms on the box; include UN1845 and net kg on the air waybill when applicable.

Is a dry ice pack 7×13 safe to handle?
Yes—use cryo-gloves and eye protection, travailler dans des zones ventilées, and never seal CO₂ in a tight container.

Can I mix a dry ice pack 7×13 with PCM panels?
Oui. Compartiments séparés, keep a vent path clear, and validate to protect 2–8 °C items from freezing.
