6. FAQ
-
Q: Can I print on both the inside and outside of the box?
- A: Yes! We specialize in Double-Sided Printing, allowing you to place your logo on the outside and a personalized message or brand story on the inside lid.
-
Q: What is the difference between E-flute and B-flute?
- A: E-flute (1.5mm) is ideal for smaller, lighter retail items and offers the best surface for high-quality graphics. B-flute (3mm) is thicker and better for heavier or more fragile items requiring extra cushioning.
-
Q: Do you offer water-resistant finishes?
- A: We offer Matte and Glossy Lamination options that provide a layer of moisture resistance and added durability to the external surface of your boxes.
