Estimar a massa de gelo seco
Usar peso da carga útil, Tamanho da caixa, tempo de rota, seasonal ambient temperature, and carrier limits before the first lane test.
Small-piece frozen route
Frozen Dumplings Cold Chain Packaging Solution
Frozen dumplings are small pieces with thin wrappers. A short thaw can cause clumping, wrapper cracks, deformação, and bag condensation. The packout must keep the dumplings frozen, protect bags from puncture, and separate dry ice from direct product contact.
Intenção de temperaturaPlan for frozen arrival, comumente -18 C or below for frozen dumpling routes.
Controle de umidadeUse a moisture barrier and separated dry ice chamber so cartons, mangas, or bags do not get wet.
Coolant ruleDo not let dry ice or hard frozen packs press directly into loose dumpling bags. Direct pressure can crack wrappers or create hard contact marks.

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, Tamanho da caixa, carrier lane, temporada, and dry ice limit.
| Condição da rota | Intenção de temperatura | Tempk packaging setup | Coolant planning range | Posição do refrigerante |
|---|---|---|---|---|
| Entrega local, 8-18 h | Frozen loose-piece quality | Insulated carton or EPP box, suporte para bolsa, barreira de umidade, separated frozen coolant or dry ice. | 1.0-1.8 kg dry ice for 1-5 kg de carga útil, or validated frozen PCM/frozen gel for controlled lanes. | Side or top chamber with divider; prevent direct pressure on dumpling bags. |
| Parcela noturna, 18-36 h | -18 C route intent | Isolamento mais espesso, bolsa de gelo seco, inner bag protection, limited headspace. | 2.0-4.0 kg dry ice for 1-5 kg de carga útil. | Perimeter dry ice separated from bags; keep bags supported to reduce puncture. |
| Hot lane or 36-48 h | Validated frozen lane | Maior isolamento, stronger outer carton, espaço vazio reduzido, route risk check. | 4.0-6.5 kg dry ice for 1-5 kg de carga útil. | If clumping appears, reduce thaw exposure and improve coolant distribution. |

Packout sequence that protects frozen quality
Frozen food returns often come from a small layout failure: direct dry ice contact, muito espaço livre, uma caixa molhada, or a product stack that shifts during handling.
1
Freeze and load quickly
Do not let dumplings sit warm during picking or kitting; a brief thaw can start clumping before transit begins.
2
Protect bags from puncture
Use inner bracing or a liner so hard coolant and box corners do not tear thin bags.
3
Separate extreme cold
Keep dry ice in a pouch or chamber with a divider so dumplings are not crushed by dry ice blocks.
4
Check loose-piece condition
Ao receber, verifique a temperatura, clumps, wrapper cracks, bag frost, perfurações, and dry ice remaining.
Common losses this packout is meant to prevent
Use these receiving checks when adjusting dry ice mass, espessura de isolamento, or internal separation.
Quality and packaging risks
- Clumped dumplings after partial thaw-refreeze.
- Wrapper cracks from pressure or direct dry ice contact.
- Bag punctures caused by hard coolant blocks or carton corners.
- Surface frost and poor customer presentation from vapor condensation.
