-
Choose correctly: When a pack of 6 dry ice pack sheet or solid CO₂ is best for your lane.
-
Size hold time: Estimate dry‑ice mass and sublimation rate per 24 ساعات بأمان.
-
Build the shipper: Pick EPS, بو, or VIP insulation for 48–72 hour deliveries.

ما هو pack of 6 dry ice pack sheet, exactly?
إجابة قصيرة: It’s a six‑panel, flexible cooling liner you hydrate and freeze. It wraps your payload to smooth out hotspots and reduce void space. Paired with solid CO₂ (الثلج الجاف) when “still frozen” is non‑negotiable, it delivers stable cold for long lanes. The 6‑sheet format scales from small parcels to mid‑size shippers while keeping weight efficient.

Why the term causes confusion: In market language, “dry ice pack sheet” may mean a قابل لإعادة الاستخدام, water‑activated sheet (no hazardous classification) or a layout used with solid CO₂. في الممارسة العملية, shippers often combine both: the six sheets provide contact and standoff; solid CO₂ supplies ultra‑low temperature buffering.

استخدم pack of 6 dry ice pack sheet وحيد for chilled or short frozen hops with premium insulation. Add solid CO₂ when deep‑frozen integrity must survive heat and delay.
| استخدام الحالة | Polymer 6‑Sheet Liner | Solid CO₂ Dry Ice | ماذا يعني لك |
|---|---|---|---|
| Frozen food 48–72 h | Helpful, but may be marginal in heat | Required for margin | Combine sheets + CO₂ for reliability |
| 2–8 °C pharma | Good fit | Usually not needed | Avoid freezing‑risk payloads |
| علم البيولوجيا الفائقة | Not applicable | Required | Validate with dual data loggers |
Practical tips that prevent failures
-
Line all six faces with the sheet; center the payload to avoid wall heat.
-
Place dry ice above الحمولة; cold air falls and stabilizes corners.
-
Pre‑chill product and liners; don’t ask the coolant to “do the initial freeze.”
حالة حقيقية: A meal‑kit brand replaced gel packs with a pack of 6 dry ice pack sheet زائد 3 kg of dry ice in PU shippers. “Soft” delivery complaints fell 28% during peak summer.

كيف أ pack of 6 dry ice pack sheet improve hold time?
فكرة أساسية: Six thin sheets create even contact and reduce thermal hotspots. That lets you use less CO₂ for the same hold time—or extend hold time with the same CO₂. With good insulation, teams routinely achieve 48–72 hours for frozen food and lab samples.

What controls performance: insulation conductivity (PU/VIP beats EPS), الحرارة المحيطة, void space, sheet coverage, and correct venting. You’ll see lower consumption (kg/24 h) when you shrink voids and use better shells.
Sizing calculator for a pack of 6 dry ice pack sheet
Use this desk‑friendly estimator, then validate with lane tests.
مثال: 60 hours in summer, PU shipper:
(60/24) × 2.8 × 1.2 × 1.0 ≈ 8.4 كيلوغرام كو₂. Round up and verify with two loggers.
| العزل | Typical λ (W·m⁻¹·K⁻¹) | Starting Rate (kg/24 h) | معنى لك |
|---|---|---|---|
| EPS | 0.03–0.045 | 3.5–4.5 | أدنى تكلفة; increase CO₂ buffer |
| بو | 0.02–0.025 | 2.5–3.0 | Strong baseline; lighter loads |
| VIP | ~0.004–0.008 | 1.8–2.5 | Max hold; highest material cost |
User tips and quick wins
-
Shrink voids: the 6‑sheet wrap fills corners and slows warm air chimneys.
-
Ship mid‑week: reduce weekend dwell time; cut required CO₂ buffer.
-
Document two trial runs: treat your first shipments as validation.
How to build a UN1845‑compliant pack‑out with a pack of 6 dry ice pack sheet?
إجابة قصيرة: Strong outer box + insulated shell + 6‑sheet liner + payload tray + dry ice in vented pockets + a lid that breathes. علامة "الثلج الجاف,"و 1845, and net weight in kg; apply the Class 9 ملصق. Train staff to keep vents open.

خطوة بخطوة (SOP‑ready)
-
هيدرات: Submerge each sheet in warm water. Scrunch until every cell swells.
-
Drain: Let excess water drip off. Faster freezing, less frost.
-
تجميد شقة: Aim for −20 °C for routine lanes; colder for longer holds.
-
Cut & مكان: Scissor between cells; cover base, walls, and lid.
-
Refreeze & rotate: Track uses; retire damaged sheets promptly.
| خطوة | Typical Time | Purpose | What You Gain |
|---|---|---|---|
| هيدرات & scrunch | 2–4 min/sheet | Fully expand cells | Even contact; fewer hotspots |
| Drain | 1–2 min | Reduce water mass | Faster freeze; lighter packout |
| تجميد شقة | 4–8 h | Lock in capacity | Predictable, repeatable cold |
| Cut to fit | 1–2 min | Custom coverage | Less void; stable temps |
Practical safety notes
-
Never place frozen sheets or CO₂ on bare skin.
-
Store dehydrated sheets dry and away from children/pets.
-
Clean gently with mild detergent before refreezing.
