Cómo realizar envíos con paquetes de gel de hielo seco reutilizables en 2025?
Paquetes de gel de hielo seco reutilizable give you clean, Frío repetible durante 24 a 72 horas sin los peligros del CO₂ sólido.. Utilízalos para mantener estables los productos congelados o refrigerados., luego vuelva a congelar y repita. En 2025, puede dimensionar los paquetes a ~25-35% de la masa de carga útil como punto de partida, validar con ISTA7E, y siga IATA PI954 solo cuando agregue hielo seco real.

¿Qué son las bolsas de gel de hielo seco reutilizables y cuándo son mejores que el hielo seco??
Son refrigerantes en gel polimérico que se congelan y reutilizan; no son CO₂ sólido. Elegir Paquetes de gel de hielo seco reutilizable for clean packouts, easy returns, and lanes that target 0 °C to subfreezing without Class 9 hazmat handling. Use real dry ice only when you truly need −78.5 °C or very long deep‑frozen duration, and then comply with IATA PI 954.
Por qué te importa: Dry ice triggers air‑freight rules (desfogue, UN1845 mark, kg neto de hielo seco, Etiqueta de clase9). Gel packs alone avoid those steps, yet you still must validate thermal performance for your lane and season.
How many reusable dry ice gel packs do you need for 24–72 hours?
Empezar 30% of payload mass for frozen foods in standard parcel lanes. Increase for hot routes (>32 °C peaks), loose voids (>25%), or 72‑hour targets. Then run an ISTA7E pilot with loggers to confirm.
| Estimador | Base | Ajuste | Lo que significa para ti |
|---|---|---|---|
| Gel mass vs. carga útil | 30% of payload kg | +20% for 72 h lanes | Longer duration needs more thermal mass |
| Calor ambiental | - | +15% if peak >32 ° C | Summer routes warm faster |
| Void ratio | - | +10% (15–25%) / +20% (>25%) | Air is a heater—fill gaps |
| “Rock‑hard on arrival” | - | Add thin −26 °C PCM topper | Deeper cold without full dry ice |
Copy‑and‑use estimator:
Run one pilot with two loggers (centro + near a corner), then tune by ±10–20%.
Consejos prácticos
-
Top‑layer rule: Place one pack on top; fregaderos fríos.
-
Tight packouts: Llenar los vacíos; keep packs in contact with the product.
-
Acondicionamiento: Congelar los paquetes por completo; partial freeze underperforms.
-
Hybrid recipe: For “rock‑hard” arrivals, add a thin −26 °C PCM topper above Paquetes de gel de hielo seco reutilizable.
Ejemplo de campo: A meal‑kit brand replaced full dry‑ice slabs with Paquetes de gel de hielo seco reutilizable plus a −26 °C PCM topper. After 7E testing, “soft on arrival” complaints dropped, and DG surcharges disappeared on ground lanes.
How do you validate Paquetes de gel de hielo seco reutilizable quickly and credibly?
Respuesta corta: Qualify under ISTA 7E/7D and write SOPs per USP <1079>. Usar MKT (USP <1079.2>) to judge brief highs/lows using the shipment’s time–temperature trace. This gives QA a science‑based, faster go/no‑go call.
What to include in your protocol: rango objetivo (p.ej., ≤−10 °C or 2–8 °C), shipper model and refrigerant count/placement, test profile & criterios de aceptación, logger locations, and MKT excursion rules.
Are gel packs compliant for air when dry ice is present?
Gel packs themselves aren’t Class 9. Si usted add dry ice, encontrarse Aquí está PI954: envasado ventilado, UN1845 + nombre de envío adecuado, kg neto de hielo seco, y un Clase9 etiqueta. Operators use standardized 2025 acceptance checklists mirroring these items.
| Lista de verificación PI954 | Que verificar | Para ti |
|---|---|---|
| Marcas | Shipper/consignee + UN1845 + nombre propio | Claro, legible exterior |
| Cantidad | Net dry‑ice weight in kg (≤200 kg/paquete) | Declare accurately |
| Etiqueta | Class 9 hazard label, correct size | Avoid tender rejections |
| Embalaje | Ventilado, exterior rígido; good condition | Prevenir la acumulación de CO₂ |
| Documento | Texto AWB / operator variations as required | Aceptación más rápida |
Poder Paquetes de gel de hielo seco reutilizable protect vaccines and biologics?
Yes—with the right material de cambio de fase (PCM). Use +5 °C PCMs or conditioned gel packs for 2–8 °C, and −20/−26 °C PCMs (optionally with gel “ballast”) for ≤−20 °C lanes. Follow the CDC Vaccine Storage & Handling Toolkit principles, including tight void control and continuous logging.
Refrigerant choices that work
| Refrigerante | Banda de temperatura | Mejor para | Lo que significa para ti |
|---|---|---|---|
| Paquetes de gel de hielo seco reutilizable | ~ 0 ° C; can support subfreezing with mass | Alimentos congelados, general perishables | Reutilizable, limpio, no dg; validate under 7E |
| Ladrillos PCM (−20 to −26 °C) | ≤ - 20 ° C | Biológicos, deep‑frozen foods | Alternativa al hielo seco; fewer handling burdens |
| hielo seco (Co₂ sólido) | −78.5 ° C | Ultralow/very long duration | Class 9 with PI 954 compliance required |
2025 cold‑chain trends for Paquetes de gel de hielo seco reutilizable
Qué hay de nuevo: Air carriers are operating against the IATA DGR 66th (2025); USP <1079.2> commentary streamlines MKT‑based excursion calls; and sub‑zero PCMs (−21 to −26 °C) are expanding dry‑ice‑free options in VIP shippers. Brands are shifting from full dry ice to Paquetes de gel de hielo seco reutilizable plus PCMs to cut DG touchpoints.

Preguntas frecuentes
Are reusable dry ice gel packs the same as dry ice?
No. They’re reusable gel refrigerants; dry ice is solid CO₂ at −78.5 °C with hazmat rules in air freight.
How long do they keep items cold?
Típicamente 24–72 horas with a right‑sized insulated shipper—confirm with an ISTA 7E/7D piloto.
How many should I start with?
Begin around 25–35% of payload mass para alimentos congelados; add for heat/voids. Validate and adjust.
Can I fly with gel packs and no dry ice?
Generalmente si; gel packs aren’t Class 9. Add dry ice → follow PI 954 (desfogue, UN1845, Kg neto, Clase9).
Are −26 °C PCMs a legal dry‑ice alternative?
Yes—widely used for frozen biologics and foods; still validate thermally.
