Low-temperature performance depends on the resin type, additives, mineral content and final material formulation. Not every PP formulation provides the same impact performance at −30°C. See Choosing Packaging Materials for −10°C and −30°C Cold Storage for the related material research and validation guidance.
Reference Produce Box Configurations
Previous project configurations provide a starting point for application review; they are project references rather than fixed catalogue dimensions.
| Application | Internal Dimensions | Board Weight |
|---|---|---|
| Broccoli Packaging Boxes | 495 × 280 × 268 mm | 800 GSM |
| Celery Packaging Boxes | 495 × 355 × 283 mm | 750 GSM |
| Asparagus Packaging Boxes | 250 × 224 × 278 mm | 750 GSM |
| Snow Pea Packaging Boxes | 380 × 279 × 135 mm | 750 GSM |
The dimensions shown are internal dimensions from previous project configurations. External dimensions vary according to the board thickness, folded structure and reinforced areas.
Final dimensions, GSM, ventilation, material formulation and box structure can be customized according to the packed product, weight, stacking height, storage temperature and transport route.
Estimated Engineering Reference
Estimated empty weight, reference product load and stacking ranges are shown for preliminary project discussion.
| Application | Estimated Empty Weight | Reference Net Product Load per Box | Reference Stacking Range |
|---|---|---|---|
| Broccoli Packaging Boxes | Approx. 0.65–0.70 kg | Approx. 8–12 kg | 8–9 layers |
| Celery Packaging Boxes | Approx. 0.75–0.85 kg | Approx. 15–20 kg | 7–8 layers |
| Asparagus Packaging Boxes | Approx. 0.31–0.34 kg | Approx. 5 kg / 11 lb | 9–11 layers |
| Snow Pea Packaging Boxes | Approx. 0.40–0.44 kg | Approx. 4–6 kg | 9–11 layers |
The values above are engineering reference estimates rather than guaranteed test results. Final empty weight, load capacity and stacking performance must be confirmed through the final die-cut design, material specification, sample production and stacking test.
Reference stacking assumes fully aligned and evenly loaded boxes placed vertically on a level pallet under static storage conditions. It does not represent guaranteed performance during vehicle vibration, uneven loading, pallet overhang, damaged-box use or other dynamic transport conditions.
