Add a 2 lb buffer for each extra day if outside temps exceed 90 °F (32 درجة مئوية).

H3: Choosing Barrier Films & Vent Liners

Film Type	CO₂ Venting	مقاومة الرطوبة	أفضل استخدام
2‑layer LDPE	قليل	معتدل	Same‑day couriers
3‑layer EVOH	واسطة	عالي	24–48 h parcels
3‑layer EVOH + Micro‑vents	عالي	عالي	48–72 h or air freight

Packing Checklist for 2025 Shipments

العزل: R‑value ≥ 7; consider 1‑in. recycled PET panels.
Dry Ice Placement: Top of payload for convection cooling; add bottom pads for > 48H.
Void Fill: Use compostable kraft crinkle to reduce air pockets.
وضع العلامات: “Dry Ice UN 1845,” net weight in kg, and shipper address.
Data Logger: NFC or Bluetooth tag to verify hold‑time on arrival.

فوز العالم الحقيقي: A seafood exporter cut spoilage from 6 % to 1 % by switching from loose pellets to 3‑lb vented bricks inside PET panels.

التعليمات

Do I need hazmat training to ship dry ice?
Ground parcels under 5.5 lb (2.5 كجم) only need proper labels; air freight requires IATA training modules.

Can I ship dry ice with lithium batteries?
Yes—pack them separately and declare both on the airway bill.

How do I dispose of leftover dry ice safely?
Let it sublimate in a well‑ventilated area; never in a sink or closed bin.

ملخص & التوصيات

Select a dry ice pack for shipping based on hold‑time, مناخ, and liner quality. Use 50 % payload weight for 48 hours, follow UN 1845 labeling, and test with a logger before scaling. Eco‑friendly films and captured‑CO₂ ice cut costs and carbon.
