1. Why are PP corrugated boxes better than cardboard for produce export?
PP corrugated boxes are waterproof, durable, and maintain their strength in refrigerated and humid environments. Unlike cardboard, they do not absorb moisture, making them better suited for cold chain transportation and long-distance export.
2. What thickness should I choose?
The ideal thickness depends on the weight of your produce, stacking height, and shipping conditions.
For most fresh produce exports:
- 3–4 mm is suitable for lightweight fruits and vegetables.
- 4–5 mm is recommended for most standard export applications.
- 5–6 mm is commonly used for heavier products such as potatoes and onions.
Your packaging supplier can recommend the most appropriate specification based on your requirements.
3. Can ventilation holes be customized?
Yes. Ventilation hole size, shape, quantity, and position can all be customized according to the produce type, cooling method, and customer requirements.
4. Are PP corrugated boxes reusable?
Yes. Under normal operating conditions, PP corrugated boxes can be reused many times, making them an excellent choice for returnable packaging systems and closed-loop logistics.
The actual service life depends on handling practices and operating conditions.
5. Are PP corrugated boxes recyclable?
Yes. Polypropylene is a recyclable material. At the end of their service life, PP corrugated boxes can be recycled and reprocessed into new plastic products, helping reduce packaging waste.
6. Can the boxes be printed with our logo?
Absolutely. PP corrugated boxes support custom printing, including company logos, product information, QR codes, barcodes, handling instructions, and full-color branding.
7. Do you offer custom sizes?
Yes. We manufacture boxes in custom dimensions to match your produce, packing line, pallet configuration, and shipping requirements.
8. Can I print my logo and handling instructions on the box?
Yes. PP supports screen printing, UV digital printing, and flexographic printing. Common markings include brand logos, produce variety, grade, country of origin, handling symbols, and traceability codes. Because PP does not absorb ink, prints stay sharp even after repeated washing — unlike cardboard, where print quality degrades as the box absorbs moisture.
