Cup-lid pressure
Stacked cups and parcel vibration can stress lids, foil seals, and multipack cartons.
Yogurt Cold Chain Packaging Solution
Yogurt shipments need chilled control plus cup, lid, and texture protection. The packout should prevent warm dwell, freezing, carton softening, and lid pressure from stacked cups.
What usually damages the shipment
A dairy shipment should be judged by both temperature and arrival condition. The packout below gives a practical starting point before lane testing and customer handoff checks.
Texture change
Warming and local freezing can both affect the expected texture and customer-facing quality.
Condensation and carton softening
Cold packs can create moisture that weakens carton board and hides lid damage.
Choose the packout by route condition
| Route condition | Temperature intent | Packaging setup | Preliminary coolant range | Receiving check |
|---|---|---|---|---|
| Short chilled route, 4-8 h | Keep the yogurt chilled according to the product requirement; avoid direct frozen contact on cup lids. | Insulated carton, cup tray, liner, small conditioned gel pack or PCM separated from the lid area. | About 0.8-1.6 kg for 6-12 retail cups. | Cup lids, carton dryness, product temperature, and handoff time. |
| Warm e-commerce route, 8-24 h | Chilled route with condensation and stack-pressure control. | EPP or insulated carton, tray/divider insert, side/top coolant with buffer, moisture-control layer, optional logger. | About 1.6-3.2 kg for 12-24 cups, adjusted by carton size. | Lid condition, texture, carton compression, label wetting, and remaining coolant. |
| Hot season or 24-36 h route | Validated chilled route with additional dwell allowance and no local freezing. | Higher-performance insulation, tray support, conditioned gel packs or PCM around the carton, logger near center and cold side. | About 3.0-5.0 kg for a larger multipack shipper; confirm by test. | Logger curve, cup/lid pressure marks, texture, carton dryness, and remaining coolant state. |
Use these ranges for sampling and quotation. Final coolant mass should be confirmed with the actual product temperature, unit count, package size, shipper volume, route duration, ambient profile, and receiving requirement.
Packout details that matter
Start with stable chilled cups
Pack from normal chilled storage. If the cups enter warm, the parcel has to remove heat and route risk increases.
Support cup layers
Use a tray, divider, or carton insert so the top layer does not crush the lower layer during courier handling.
Keep coolant off the lids
Place conditioned coolant around the tray with a buffer layer so it cools the air space without pressing on lids.
Check texture and presentation
Receiving should review temperature, lid seal, carton dryness, texture, label clarity, and remaining coolant.
Common losses to prevent
These are the visible and operational issues the packout should reduce before the shipment reaches the receiver.
- Bulged or loosened lids
- Softened cartons from condensation
- Texture change after warm or frozen exposure
- Crushed multipacks from poor stacking support
Route validation image
Use the test curve as a working comparison, then validate with the actual product, coolant mass, insulation, route duration, and season. For dairy, also check leakage, condensation, package pressure, texture, odor, and remaining coolant.
