Use payload weight, حجم المربع, وقت الطريق, seasonal ambient temperature, and carrier limits before the first lane test.
Flat frozen carton route
Frozen Pizza Cold Chain Packaging Solution
Frozen pizza needs a flat, جاف, frozen route. The packout must protect crust shape, topping position, paperboard cartons, and stacked-case pressure while keeping dry ice or frozen coolant away from direct paperboard contact.
نية درجة الحرارةPlan for frozen arrival, عادة -18 C or below when the route is specified as frozen.
مراقبة الرطوبةUse a moisture barrier and separated dry ice chamber so cartons, الأكمام, or bags do not get wet.
Coolant ruleDo not place loose dry ice directly against retail pizza cartons. Direct contact and vapor moisture can damage paperboard or create localized quality defects.

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 |
|---|---|---|---|---|
| التسليم المحلي, 8-18 ح | Frozen arrival | Flat EPP box or insulated carton, carton sleeve, حاجز الرطوبة, light top bracing. | 1.0-1.8 kg dry ice for 1-5 حمولة كجم, or validated frozen PCM/frozen gel for controlled local routes. | Above or side chamber with divider; keep pizzas flat and dry. |
| الطرود بين عشية وضحاها, 18-36 ح | -18 C route intent | عزل أكثر سمكا, dry ice pouch or chamber, vapor gap, flat stack support. | 2.0-4.0 kg dry ice for 1-5 حمولة كجم. | Top dry ice separated from cartons; avoid edge crushing and carton wet-out. |
| Hot lane or 36-48 ح | Validated frozen lane | عزل أعلى, reduced headspace, كرتون خارجي قوي, route risk check. | 4.0-6.5 kg dry ice for 1-5 حمولة كجم, subject to carrier limit. | إذا كانت الكراتين طرية, improve moisture barrier before adding more dry ice. |

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
Keep pizzas flat from loading to delivery
Use bracing or a snug product chamber so cartons do not bend when the parcel is tilted or stacked.
2
Separate dry ice from paperboard
Use a dry ice pouch, مقسم, or chamber so vapor and extreme cold do not attack the retail carton.
3
Control headspace
Large air gaps increase sublimation and allow cartons to move; fit the shipper to the pizza stack height.
4
Receive by condition
Check product temperature, dry ice remaining, carton wet-out, crust breakage, and signs of thaw-refreeze.
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
- Soft or wet pizza cartons from vapor condensation.
- Broken crusts or warped cartons from poor flat support.
- Topping shift after partial thaw during last-mile delay.
- Localized carton damage from direct dry ice contact.

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.
