تقدير كتلة الجليد الجاف
Use payload weight, حجم المربع, وقت الطريق, seasonal ambient temperature, and carrier limits before the first lane test.
Tray and seal frozen route
Frozen Ready Meals Cold Chain Packaging Solution
Frozen ready meals often combine trays, film seals, الصلصات, أرز, المعكرونة, خضروات, and sleeves in one pack. The route must keep meals frozen while protecting tray seals, sleeve labels, sauce texture, and stacked tray corners.
نية درجة الحرارةPlan for frozen arrival, عادة -18 C or below for frozen ready meal distribution.
مراقبة الرطوبةUse a moisture barrier and separated dry ice chamber so cartons, الأكمام, or bags do not get wet.
Coolant ruleDo not size the packout only by payload weight. Sauce-heavy meals, shallow trays, and paper sleeves need extra attention to seal pressure and condensation.

Choose the packout by route condition
The dry ice amounts below are starting ranges for planning. Final packout should be validated with the exact payload, حجم المربع, ممر الناقل, موسم, and dry ice limit.
| حالة الطريق | نية درجة الحرارة | Tempk packaging setup | Coolant planning range | موقف المبرد |
|---|---|---|---|---|
| Local meal delivery, 8-18 ح | Frozen arrival | EPP or insulated carton, tray stack support, sleeve moisture barrier, separated frozen coolant or dry ice. | 1.0-2.0 kg dry ice for 1-5 حمولة كجم, or validated frozen PCM/frozen gel for short lanes. | Side/top coolant with divider; avoid pressure on film seals. |
| Overnight frozen parcel, 18-36 ح | -18 C route intent | عزل أكثر سمكا, كيس الثلج الجاف, tray corner support, انخفاض مساحة الفراغ. | 2.0-4.5 kg dry ice for 1-5 حمولة كجم. | Top dry ice separated by board; keep logger in product air space. |
| Hot lane or 36-48 ح | Validated frozen lane | عزل أعلى, stronger tray bracing, route risk check, carrier limit review. | 4.0-7.0 kg dry ice for 1-5 حمولة كجم. | If tray seals lift, reduce pressure and improve bracing before changing dry ice mass. |

Packout sequence that protects frozen quality
Frozen food returns often come from a small layout failure: direct dry ice contact, الكثير من مساحة الرأس, كرتونة مبللة, or a product stack that shifts during handling.
1
Protect tray seals first
Seal failure creates a return even if the temperature curve looks acceptable.
2
Separate dry ice from sleeves and film
Use a divider or dry ice chamber so sleeves do not wrinkle and tray film is not stressed by direct contact.
3
Match packout to meal composition
Sauce-heavy meals, rice bowls, and pasta trays show thaw-refreeze differently; check the real product.
4
Inspect receiving quality
سجل درجة الحرارة, سلامة الختم, tray cracks, sleeve moisture, sauce separation, and dry ice remaining.
Common losses this packout is meant to prevent
Use these receiving checks when adjusting dry ice mass, سمك العزل, or internal separation.
Quality and packaging risks
- Tray seal lift or corner cracks from pressure and movement.
- Sauce separation after partial thaw-refreeze.
- Wet sleeves or unreadable labels from vapor condensation.
- Warm top trays when coolant is placed only below the stack.
أدوات, عناصر, and related routes
Use the product page for the handling logic, then size the first trial with tools and validate the real route.
Choose coolant behavior
Compare dry ice, عبوات جل مجمدة, and frozen PCM when choosing the first frozen packout.
Check route risk
Review pickup dwell, تأخير الميل الأخير, receiving window, and summer routing before launch.
