What is a dry ice pack 7×13, y cuando deberías usarlo?

A dry ice pack 7×13 is a vented 7×13-inch pouch you fill with dry-ice pellets, Proporciona refrigeración de fuente de -78,5 °C para carriles congelados.. 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, reduce los espacios de aire, and fits small parcel coolers efficiently.

Why it’s useful for you: The format blankets small loads without heavy overpack. It produces no meltwater, mantiene las cajas secas, 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 cargas

Comenzar con ~1–1.5 lb (0.45–0.7 kg) de hielo seco por 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	que es	Que comprobar	Lo que significa para ti
Dry-ice source	Solid CO₂ at −78.5 °C	Tamaño del pellet, frescura	Predictable ultracold performance without liquid residue.
7×13 bag	Vented CO₂-safe pouch	Seam integrity, ruta de ventilación	Gas escapes; reduced rupture risk and easier air acceptance.
Remitente	EPS, PPE, personaje, rigid coolers	valor R, paquete apretado	Lower sublimation and longer hold time for same mass.

Consejos prácticos y sugerencias.

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

Caso del mundo real: A dessert brand used two dry ice pack 7×13 units in a 10 L shipper for 2-day air during 32 ° C Ambient. 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: estimar 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.

Guía ampliada: Start with the volume-based baseline, multiply by time and a lane factor (1.0 Frío, 1.25 promedio, 1.5 caliente), then divide by your typical per-pack fill. Coloque uno 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.

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

Do four things: envasado de ventilación, Aplicar la clase 9 etiqueta, 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. Por la seguridad de los trabajadores, use cryo-gloves, protección para los ojos, and good ventilation.

Por qué te importa: 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

ventilarlo: Packaging must permit CO₂ release; never fully seal coolers.
Márcalo: Imprimir UN1845 y peso neto de hielo seco (kilos) en la caja exterior.
Etiquétalo: Aplicar la clase 9 etiqueta de peligro; place where visible after handling.
Document it: Show UN1845 and net kg on the air waybill when applicable.

Elemento de etiquetado	Requisito	Common slip	Lo que significa para ti

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 la práctica: Top-blanket a dry ice pack 7×13 to protect frozen SKUs, then place +5 °C PCM panels closer to sensitive items. This limits freeze risk, simplifica el cumplimiento, 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 solo; maximize insulation before adding mass.
Strict 2–8 °C corridors: Prefer PCM first; add minimal dry-ice buffer if needed.
Cargas útiles mixtas: Usa un divisor; combine PCM and dry ice pack 7×13 with a clear vent path.

2025 trends shaping dry ice pack 7×13 uso

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.

Último progreso de un vistazo

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 contar.

Insight del mercado: 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.

Preguntas frecuentes

How long will a dry ice pack 7×13 último?
Plan for 24–72 hours depending on insulation, calor ambiental, and fill mass. Comience con 1 a 1,5 libras por 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?
Aplicar la clase 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 seguro de manejar?
Yes—use cryo-gloves and eye protection, trabajar en áreas ventiladas, and never seal CO₂ in a tight container.

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

Resumen y recomendaciones

Puntos clave: A dry ice pack 7×13 delivers ultracold, residue-free performance for frozen lanes. Respiradero, mark UN1845 with net-kg, y sigue a PI 954/49 reglas CFR. Rightsize with the three-step calculator, then validate on your lanes with data loggers. Consider hybrids for mixed payloads.

Siguientes pasos: Map lanes by season and hold time. Pilot two packouts with different dry ice pack 7×13 cuenta. Actualizar los SOP con 2025 label/mark steps and add the acceptance checklist. Embed the calculator on your site. CTA: Request a validated packout and documentation kit from Tempk.
