Bestes Trockeneis-Packblatt: Wie wählen Sie in 2025?

If you’re looking for the best dry ice pack sheet in 2025, this guide will help you make the right decision: dry ice sheets are a vital part of temperature-sensitive logistics, ensuring your products stay frozen throughout transit. In diesem Artikel, we’ll explore how to choose, verwenden, and optimize them effectively for your business.

Wählen Sie das Richtige Trockeneisschütze für Essen, Pharma, and DTC lanes (0–10 ° C)
Size coolant fast with a lane-time calculator to avoid DIM weight
Meet safety rules for true dry ice (UN1845) and avoid delays
Compare sheets, Gelpackungen, and PCMs to reduce waste and cost

What exactly is a “dry ice pack sheet” in 2025?

Fazit: A Trockeneisschütze is a flexible cooling material designed to maintain sub-zero temperatures during transport. Choosing the best dry ice pack sheet means finding one that balances cooling efficiency, Haltbarkeit, und Kosten.

Key differences vs gel packs and PCMs

Kühlmethode	Arbeitsbereich	Typische Dauer	What changes your choice	Was es für Sie bedeutet
Trockeneis-Packblatt (SAFT)	~ 0 ° C.	12–48H (with proper packout)	Insulation R-value, Flüssigkeitszufuhr, packing pattern	Niedrigere Kosten, flexible wrap, quick to deploy
PCM-Ziegel/Fliesen	−25 °C to +25 °C (verschieden)	24–96H	Validation needs, Investitionen, pre-conditioning time	Tight control for audits and stability
Echtes Trockeneis (Co₂)	≈ –78,5 ° C.	Highly variable (Sublimation)	IATA UN1845 rules, Entlüftung, carrier policies	Ultralow temp; hazmat training required

Praktische Tipps und Ratschläge:

Essen & meal-kit lanes: Sheets are ideal for 0–10 °C when you line sides and cap the top.
Clinical 2–8 °C: PCMs reduce variability and simplify validation record-keeping.
Tiefgefroren: Use solid CO₂ only with proper labels and vented packaging.

Fall der realen Welt: A DTC seafood brand replaced bulk gel with sheet “wraps” and a top cap. Hold-time met a 36-hour lane, shipping weight dropped by 1.2 kg, and claims fell by half.

How do you evaluate the “best” sheet for your shipment?

Kurze Antwort: Score each candidate on five factors—thermal performance, Auslaufsicherheit, handling safety, regulatory fit, and total landed cost—and run a lane test. A simple 6–8 hour bench profile (ambient 23 °C, payload 2–8 °C) predicts most 1‑ to 2‑day scenarios.

Thermal performance checklist

Flüssigkeitszufuhr: 60–70× sheet mass in water is typical; drain excess to prevent sweating.
Freeze regimen: −18 to −25 °C for 24–48 hours; lay flat to freeze uniformly.
Pack density: Kopfraum füllen; sheet cells should face payload surfaces.
Validierung: Record core temp every 5 minutes with a logger to verify duration.

Leak and handling checklist

Use double-sealed or textile-reinforced cells to reduce punctures.
Bag sheets or use film liners to control condensation.
Train packers on scissors/box-cutter technique to avoid accidental nicks.

Safety and compliance in plain English

True dry ice is regulated as a Class 9 Gefahrgut (Und 1845). If you ship with solid CO₂, Folge HIER PI 954, Markieren Sie "Trockeneis" (oder „Kohlendioxid, solide"), die UN -Nummer, and the net mass in kilograms, und wenden Sie die Klasse an 9 Etikett. Ensure venting to avoid CO₂ buildup.

For water-based sheets (no CO₂), you avoid those hazmat labels, but you still need food contact documentation if touching edible goods, and good manufacturing and sanitation practices for pack rooms.

CO₂ exposure basics packers should know

CO₂ kann Sauerstoff verdrängen; OSHA TWA is 5,000 ppm; Idlh 40,000 ppm.
Dry ice causes frostbite on contact; use insulated gloves and eye protection.
Trockeneis niemals in luftdichten Behältern verschließen; pressure can build dangerously.

How to size your coolant in minutes

Start with your lane time plus a 20% Puffer. Multiply by your shipper’s heat gain rate (W/°C) and the temperature delta. Convert the watt-hours to the mass of frozen water required; then map to sheets by total hydrated mass.

Packing pattern that just works

Pre-chill shipper and payload.
Line sides with 2–3 plies; place a full sheet on top.
Use dunnage to eliminate air gaps; close fast to reduce meltback.

2025 trends that affect your choice

Meal-kit and DTC growth demands lighter, cheaper coolants with reliable 0–10 °C control.
Pharma adds traceability and validation pressure, increasing interest in PCMs for narrow bands.
Carrier enforcement of UN1845 labels stays strict; training and checklists reduce delays.

Quick progress highlights

Reusable PCM tiles extend hold times and reduce waste in validated lanes.
Reinforced ice blankets cut punctures in dense kitted boxes.
Bench testing with affordable loggers guides right-sizing and saves freight.

Quick comparison table (performance and cost signals)

Faktor	Sheet‑forward packout	PCM‑forward packout	Was es für Sie bedeutet
Hold‑time stability	Medium	Hoch	PCMs smooth spikes; weniger Ausflüge
Up‑front cost	Niedrig	Mittel–Hoch	Sheets reduce capex; PCMs pay off in audits
Storage footprint	Niedrig (trocken, Wohnung)	Medium (pre‑frozen)	Easier to scale seasonal volume
SOP complexity	Einfach	Mäßig (pre‑conditioning)	Less training vs. timed staging

FAQ

Q1: Are “dry ice pack sheets” the same as dry ice?
A: NEIN. They are water-based SAP ice blankets. True dry ice is solid CO₂ and regulated differently.

Q2: How long do sheets keep 2–8 °C?
A: In a medium EPS shipper, a full top sheet plus side plies often covers 24–48 hours, but validate your lane.

Q3: Can I use sheets with seafood?
A: Ja, if bagged appropriately. Keep direct food contact compliant and separate raw from ready-to-eat.
