Utiliser le poids de la charge utile, taille de boîte, temps de parcours, 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, sec, 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.
Intention de températurePlan for frozen arrival, communément -18 C or below when the route is specified as frozen.
Contrôle de l'humiditéUse a moisture barrier and separated dry ice chamber so cartons, manches, or bags do not get wet.
Règle du liquide de refroidissementDo not place loose dry ice directly against retail pizza cartons. Direct contact and vapor moisture can damage paperboard or create localized quality defects.
Réception du chèqueConfirmer la température du produit, dry ice remaining, visible thaw, pack condition, and coolant position together.
Choisissez le pack par condition d'itinéraire
The dry ice amounts below are starting ranges for planning. Final packout should be validated with the exact payload, taille de boîte, carrier lane, saison, and dry ice limit.
| État de l'itinéraire | Intention de température | Tempk packaging setup | Coolant planning range | Emplacement du liquide de refroidissement |
|---|---|---|---|---|
| Livraison locale, 8-18 h | Frozen arrival | Flat EPP box or insulated carton, carton sleeve, barrière contre l'humidité, light top bracing. | 1.0-1.8 kg dry ice for 1-5 kg de charge utile, or validated frozen PCM/frozen gel for controlled local routes. | Above or side chamber with divider; keep pizzas flat and dry. |
| Colis de nuit, 18-36 h | -18 C route intent | Isolation plus épaisse, dry ice pouch or chamber, vapor gap, flat stack support. | 2.0-4.0 kg dry ice for 1-5 kg de charge utile. | Top dry ice separated from cartons; avoid edge crushing and carton wet-out. |
| Hot lane or 36-48 h | Validated frozen lane | Isolation supérieure, reduced headspace, carton extérieur solide, route risk check. | 4.0-6.5 kg dry ice for 1-5 kg de charge utile, subject to carrier limit. | Si les cartons ramollissent, 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, trop d'espace libre, un carton mouillé, 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, diviseur, 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 mouillé, crust breakage, and signs of thaw-refreeze.
Pertes courantes que ce pack est censé éviter
Use these receiving checks when adjusting dry ice mass, épaisseur d'isolation, or internal separation.
Risques qualité et emballage
- 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.
