What is a dry ice pack 7×13, dan kapan Anda harus menggunakannya?

A dry ice pack 7×13 is a vented 7×13-inch pouch you fill with dry-ice pellets, memberikan sumber pendinginan −78,5 °C untuk jalur beku. 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, mengurangi celah udara, and fits small parcel coolers efficiently.

Why it’s useful for you: The format blankets small loads without heavy overpack. It produces no meltwater, menjaga karton tetap kering, 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 banyak

Mulailah dengan ~1–1.5 lb (0.45–0.7 kg) es kering per 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. Untuk rute panas, add 25–50% more than winter baselines.

Packout component impact	Apa itu	Apa yang harus diperiksa	Apa artinya bagimu
Dry-ice source	Solid CO₂ at −78.5 °C	Ukuran pelet, kesegaran	Predictable ultracold performance without liquid residue.
7×13 bag	Vented CO₂-safe pouch	Integritas jahitan, jalur ventilasi	Gas escapes; reduced rupture risk and easier air acceptance.
Pengirim terisolasi	EPS, EPP, VIP, rigid coolers	Nilai-R, paket ketat	Lower sublimation and longer hold time for same mass.

Tips dan saran praktis

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

Kasus dunia nyata: 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: estimate 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.

Panduan yang diperluas: Start with the volume-based baseline, multiply by time and a lane factor (1.0 Dingin, 1.25 rata-rata, 1.5 panas), then divide by your typical per-pack fill. Tempatkan satu 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.

Contoh nyata: A diagnostics shipper cut complaints by switching to two dry ice pack 7×13 plus a vented lid; logger traces confirmed 48-hour stability.

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

Do four things: Ventilasi Kemasan, Terapkan kelas 9 label, 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. For worker safety, use cryo-gloves, pelindung mata, and good ventilation.

Mengapa itu penting bagi Anda: 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

Curhatlah: Packaging must permit CO₂ release; never fully seal coolers.
Tandai itu: Mencetak UN1845 Dan berat bersih es kering (kg) di kotak luar.
Beri labelnya: Terapkan Kelas 9 label bahaya; place where visible after handling.
Document it: Show UN1845 and net kg on the air waybill when applicable.

Elemen pelabelan	Persyaratan	Common slip	Apa artinya bagimu
UN1845 text	On outer package	Missing net kg	Delays or refusal at acceptance.
Kelas 9 label	Per IATA/Carrier	Wrong placement	Re-work and missed uplift.
Jalur ventilasi	“Must permit release”	Taped-shut lid	Rupture risk; non-compliant.

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.

Dalam praktiknya: Top-blanket a dry ice pack 7×13 to protect frozen SKUs, lalu letakkan +5 °C PCM panels closer to sensitive items. This limits freeze risk, menyederhanakan kepatuhan, 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: Kebaikan dry ice pack 7×13 hanya; maximize insulation before adding mass.
Strict 2–8 °C corridors: Prefer PCM first; add minimal dry-ice buffer if needed.
Muatan campuran: Gunakan pembatas; combine PCM and dry ice pack 7×13 with a clear vent path.

2025 trends shaping dry ice pack 7×13 penggunaan

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.
