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 Assembly Ease

Key Consideration: Selecting the wrong tuck depth causes poor closure.
Tip: We optimize tuck depth for reliable, one-handed closure.

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.
