How Much Dry Ice to Pack Food for Shipping?
Schnelle Regel: Planen 5–10 lb of dry ice per 24 hours of transit, then add one extra day as a buffer. Use the higher range for hot weather, dünne Isolierung, or small pellets that sublimate faster. Always write the net weight in kilograms on the outside label.
Warum funktioniert das: Dry ice sublimates at –79 °C (–110 °F), absorbing large amounts of heat as it turns to CO₂ gas. This makes it efficient for maintaining frozen temperatures in insulated containers.
Example Sizing Table
| Transitzeit | Trockeneis benötigt | What It Means for You |
|---|---|---|
| 12–24 h | 5–10 lb | Thick insulation → 5 lb; hot lanes → 10 lb |
| 48 H | 10–20 lb | Prefer blocks or ≥10 mm pellets |
| 72–96 h | 20–40 lb | Test runs recommended; limit door openings |
| 120 H | 40–60 lb | VIP shippers reduce required weight by ~25% |
Which Packaging Works Best to Use Dry Ice to Pack Food?
Core setup: Always use an insulated container (EPS -Schaum, Pur, or VIP for long routes), mit Trockeneis placed above the food since cold air sinks. Packages must be vented to release CO₂ gas.
Pellets vs. Blöcke
-
Blöcke (längerer Halt): Last 48–96 hours, slower sublimation.
-
Pellets (faster chill): Great for quick cooling but sublimate faster.
-
Hybrid: Blocks at the base + pellets on top balance speed and longevity.
Container Choices
| Container Type | Am besten für | Warum es dir hilft |
|---|---|---|
| EPS Foam Shipper | 24–48 h | Budget-friendly, easy to source |
| VIP Shipper | 72–120 h | Uses less dry ice; higher upfront cost |
| Hartes Kühler | Multi-use | Dauerhaft, wiederverwendbar, good for rough handling |
Was sind die 2025 Rules for Shipping with Dry Ice?
Air shipments (Iata 2025): Markieren „Trockeneis/Kohlendioxid, solid – UN1845”, enthalten Nettogewicht in kg, shipper/consignee details, und eine Klasse anwenden 9 Etikett. Use the IATA 2025 Acceptance Checklist when a Shipper’s Declaration isn’t required.
USPS: Maximum 5 lb per air mailpiece, Nur inländisch, no international.
UPS & FedEx: Follow PI954 rules. FedEx Ground does not treat dry ice as hazardous, but you must still mark the package. UPS may require an ISC contract for international air shipments.
Safety Tips When You Use Dry Ice to Pack Food
-
Belüftung: Never seal containers airtight; dry ice releases CO₂ gas.
-
Handhabung: Always wear insulated gloves; Vermeiden Sie direkten Hautkontakt.
-
Expositionsgrenzen: OSHA sets 5,000 ppm TWA and 30,000 ppm STEL for CO₂ in workplaces.
-
Recipient notice: Inform the recipient the package contains dry ice.
Real Case: A bakery reduced “soft-on-arrival” claims by 35% after switching from pellets to block-dominant dry ice for 2-day routes. Same weight, längerer Halt.
2025 Market and Technology Trends
-
Updated Regulations: IATA 66th DGR Addendum effective April 2025; USPS continues 5 LB Air Cap.
-
VIP Shippers Mainstream: More frozen lanes use vacuum-insulated panels to cut dry ice needs.
-
Intelligente Überwachung: QR-enabled TTIs and Bluetooth loggers provide full cold-chain visibility.
-
Nachhaltiges Trockeneis: Suppliers are increasingly using reclaimed CO₂, lowering environmental impact.
