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.

Reference internal dimensions and board weights
ApplicationInternal DimensionsBoard Weight
Broccoli Packaging Boxes495 × 280 × 268 mm800 GSM
Celery Packaging Boxes495 × 355 × 283 mm750 GSM
Asparagus Packaging Boxes250 × 224 × 278 mm750 GSM
Snow Pea Packaging Boxes380 × 279 × 135 mm750 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.

Estimated engineering reference for previous produce box configurations
ApplicationEstimated Empty WeightReference Net Product Load per BoxReference Stacking Range
Broccoli Packaging BoxesApprox. 0.65–0.70 kgApprox. 8–12 kg8–9 layers
Celery Packaging BoxesApprox. 0.75–0.85 kgApprox. 15–20 kg7–8 layers
Asparagus Packaging BoxesApprox. 0.31–0.34 kgApprox. 5 kg / 11 lb9–11 layers
Snow Pea Packaging BoxesApprox. 0.40–0.44 kgApprox. 4–6 kg9–11 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.

Frequently Asked Questions

What materials are used for these boxes?

The boxes use a PP and calcium carbonate formulation. Final thickness and GSM are selected according to the packed product, weight, stacking and transport requirements.

Can the size, structure and printing be customized?

Yes. Dimensions, die-cut structure, ventilation, drainage, hand holes, closures, colors and printing can be customized according to the project.

How are thickness, GSM, load and stacking requirements confirmed?

They are confirmed according to the packed product, weight per box, stacking height, storage conditions and transport method.

Are samples and relevant documents available?

Samples can be prepared after the main specifications are confirmed. Available documents depend on the selected material and project requirements.

What are the MOQ and typical lead time?

The standard MOQ is 5,000 pieces. Lead time is 10–15 days after final specifications and artwork are confirmed.

Can drainage holes be added for wet handling?

Optional drainage openings can be reviewed for washed produce, condensation and wet handling routes. Final placement depends on the box structure and handling process.

Can ventilation holes be customized?

Yes. Hole size, quantity and position can be reviewed according to cooling, airflow, product protection and stacking requirements.
