Common Mistakes to Avoid

Wrong Flute Selection

Key Consideration: Using E-flute for heavy items causes box collapse.
Tip: Use BE-flute for items over 8kg or for international shipping.

Ignoring Production Time

Key Consideration: Ordering too close to launch date.
Tip: Allow 2-3 weeks for production plus shipping time.

Poor File Quality

Key Consideration: Low-resolution artwork results in blurry printing.
Tip: Provide 300dpi minimum, convert text to outlines, use CMYK color mode.

No Protective Inserts

Key Consideration: Products move inside box causing damage.
Tip: Add custom inserts for fragile or multiple items.
