Estimer la masse de glace carbonique
Utiliser le poids de la charge utile, taille de boîte, temps de parcours, 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, sauces, riz, pâtes, légumes, and sleeves in one pack. The route must keep meals frozen while protecting tray seals, sleeve labels, sauce texture, and stacked tray corners.
Intention de températurePlan for frozen arrival, communément -18 C or below for frozen ready meal distribution.
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 size the packout only by payload weight. Sauce-heavy meals, shallow trays, and paper sleeves need extra attention to seal pressure and condensation.
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 |
|---|---|---|---|---|
| Local meal delivery, 8-18 h | 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 kg de charge utile, or validated frozen PCM/frozen gel for short lanes. | Side/top coolant with divider; avoid pressure on film seals. |
| Overnight frozen parcel, 18-36 h | -18 C route intent | Isolation plus épaisse, pochette de glace carbonique, tray corner support, espace vide réduit. | 2.0-4.5 kg dry ice for 1-5 kg de charge utile. | Top dry ice separated by board; keep logger in product air space. |
| Hot lane or 36-48 h | Validated frozen lane | Isolation supérieure, stronger tray bracing, route risk check, carrier limit review. | 4.0-7.0 kg dry ice for 1-5 kg de charge utile. | 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, trop d'espace libre, un carton mouillé, 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
Enregistrer la température, intégrité du joint, tray cracks, sleeve moisture, sauce separation, and dry ice remaining.
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
- 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.

Choose coolant behavior
Compare dry ice, packs de gel congelés, and frozen PCM when choosing the first frozen packout.
Vérifier le risque d'itinéraire
Review pickup dwell, retard du dernier kilomètre, receiving window, and summer routing before launch.
