What is a dry ice pack and why does naming matter?

In industry practice, a dry ice pack is a CO₂‑based refrigerant assembly for ultra‑cold shipping. The term can also refer to polymer sheets that hydrate and freeze, but those are not CO₂. To avoid errors, specify whether you need CO₂ dry ice pack or a polymer ice sheet, especially in regulated lanes.

When you order a Paket es kering, ask for UN1845 CO₂ if your product requires below −70 °C. Some vendors market hydratable sheets as a Paket es kering because the surface stays dry. Those sheets are reusable and safer to handle, yet they cannot match the extreme cold of a CO₂ solution. Use the polymer option for 2–8 °C or −20 °C ranges; Pilih A Paket es kering when deep‑freeze or ultra‑cold control is mandatory.

Encapsulated inserts and smoother temperature profiles

Encapsulated inserts that hold pellets in a tray reduce product cold shock and keep a steadier micro‑climate. Blocks last longer because of lower surface‑area‑to‑mass; pellets pull down fast and are easier to dose. For lanes with frequent door‑opens, a lidded insert above the payload helps keep the Paket es kering from over‑cooling sensitive vials.

Tips Praktis & kemenangan cepat

• Door‑open events: Open slowly in a ventilated area; close promptly.

• Carton fit: Isi kekosongan; air gaps accelerate Paket es kering burn‑off.

• Block vs pellet: Use more blocks in hot seasons; pellets to pre‑cool before handoff.

Contoh dunia nyata: A lab shipping enzyme kits moved from loose pellets in EPS to a lidded insert with more blocks. Hold time rose from 48 h to 72 h on a hot‑season profile, and temperature excursions went to zero across three pilots.

Berapa lama paket es kering bertahan, and how much do you need?

Plan by time and expected sublimation, then add a safety buffer. In a mid‑size insulated shipper, the refrigerant often loses several kilograms per day. Warmer profiles, busa tipis, and frequent openings increase the rate; vacuum‑insulated panels slow it. FAA testing shows pellets sublimate faster than large blocks, reinforcing the “faster pull‑down vs longer hold” trade‑off.

How do you pack a shipment with a dry ice pack safely in 2025?

Lubang angin, label, and separate payload from the cold source. Use a rigid insulated shipper that permits gas release; never make it air‑tight. Tanda “Es kering” atau “karbon dioksida, padat", termasuk UN1845 dan Berat bersih on the airway bill and box. Deklarasi Pengirim adalah tidak diperlukan when cooling non‑dangerous goods; operator variations may apply.

Catatan USPS (udara): ≤ 5 lb es kering per surat; international mail is prohibited. Ensure packaging vents CO₂.

1. Pre‑condition the shipper and stage the payload at its qualified temperature.

2. Place a bottom layer of blocks or pellets in a vented sleeve or tray.

3. Add a buffer so product does not sit directly on the cold source unless validated.

4. Muat muatannya; top off with the remaining mass from your calculation.

5. Close without sealing air‑tight; apply marks and labels; brief the receiver on opening SOP.

Keamanan pertama: ventilasi, APD, and facility controls

Protect people first. Carbon dioxide can quickly displace oxygen; target below 5,000 ppm time‑weighted average and below 30,000 ppm jangka pendek. Gunakan sarung tangan terisolasi dan pelindung mata, ventilasi kendaraan dan ruangan, and avoid storing any Paket es kering in sealed containers.

One pound of dry ice becomes ~250 L gas, so even a small charge can over‑pressurize a closed cooler. Add a CO₂ monitor in enclosed docks and vans, train teams on safe opening, and keep SOP cards with every shipment.

2025 trends in ultra‑cold shipping

Apa yang baru tahun ini: Sensor pintar, validated hybrid shippers, and standardized lane testing. Many teams pair a Paket es kering with PCM “buffers” to flatten spikes and cut total ice mass. Qualification to ISTA 7E profiles speeds audits and reduces excursion risk on hot lanes.

Perkembangan terbaru sekilas

• VIP + Hibrida PCM: Longer hold with less CO₂; smoother profiles.

• Daftar periksa penerimaan: Faster airline checks when cooling non‑DG goods.

• pemantauan CO₂: Portable sensors on docks and vans to protect staff.

Wawasan pasar: Demand remains strong in healthcare and food e‑commerce. Shippers that right‑size their Paket es kering and validate to lane profiles reduce cost, limbah, and claims.

Pertanyaan yang sering diajukan

Is a dry ice pack the same as a polymer ice sheet?
TIDAK. A Paket es kering typically uses solid CO₂ that vents; a polymer sheet is water‑based and reusable. Confirm which one your lane requires.

Do I need a dangerous goods declaration for CO₂ refrigerant?
When it cools non‑dangerous goods, a declaration is usually not required, Tetapi UN1845, nama yang tepat, and net weight must appear on the waybill and package.

How much do I need for 48 jam?
Start with 3–4.5 kg per day in a mid‑size VIP/EPS shipper, menambahkan 20% penyangga, dan validasi dengan logger.

Can I seal the box tightly to trap cold?
TIDAK. Packages must vent CO₂ to avoid pressure build‑up and rupture risk. Pi 954 requires gas release.

Is it safe for food?
Ya, but avoid direct contact with unpackaged food to prevent freezer burn; always use a barrier bag.

Ringkasan & Rekomendasi

Kunci takeaways: A Paket es kering is the simplest way to achieve ≤ −70 °C on long lanes. Vent every package and mark UN1845 dengan bobot bersih. Size by time and expected sublimation plus buffer, and validate against lane profiles to prevent excursions.

Langkah selanjutnya: Map your lane, estimate mass with the formula, run a pilot with data logging, then standardize your SOP. Ready for a lane‑based plan? Dapatkan yang disesuaikan Paket es kering configuration and validation checklist from our team.
