Common Mistakes to Avoid
Overloading the Box
Key Consideration: Folding cartons have weight limits based on cardboard thickness.
Tip: For items over 3kg, consider upgrading to thicker cardboard (400gsm) or a reinforced structure.
Wrong Score Depth
Key Consideration: Incorrect scoring causes cracking or uneven folds.
Tip: Request test folds before bulk production to verify fold quality.
Humid Storage Conditions
Key Consideration: Cardboard can absorb moisture and lose structural integrity.
Tip: Store in dry environment. Consider moisture-resistant lamination for humid climates.
Ignoring Artwork Bleed
Key Consideration: Designs without proper bleed may show white edges after trimming.
Tip: Always provide artwork with 3mm bleed on all sides.
