Score cracking—visible fiber breakage along a fold—can ruin a carton’s appearance, weaken its structure, and cause failures on automated lines. Understanding the causes and engineering solutions is critical for producing folding cartons that maintain both strength and visual quality. What Causes Score Cracking Score cracking occurs when fibers along the fold line break instead of bending cleanly. Low Moisture Content: Dry board becomes brittle and less pliable (ASTM D685-22). Improper Score Depth: Shallow scores increase folding resistance; deep scores can cut fibers. Incorrect Grain Direction: Folding parallel to the grain increases cracking risk. Surface Coating Rigidity: Gloss varnish, films, and metallic layers reduce fiber flexibility. Material Selection SBS (Solid Bleached Sulfate): Generally folds cleanly but can crack with heavy coatings or low EMC. CUK (Coated Unbleached Kraft): Higher tear resistance; better for humid conditions. FBB (Folding Boxboard): Softer surface layers reduce cracking risk in coated applications. Tip: Match fiber composition and surface finish to the intended folding radius and production environment. Moisture and Conditioning Pre-Production Conditioning: Allow board to reach equilibrium moisture content (TAPPI T402). Humidity Control: Maintain 40–60% RH in converting and packing areas. Target EMC: Typically 5–8% for most paperboard grades. Coating and Lamination Adjustments Scoring After Coating: Where possible, score post-coating to reduce fiber breakage. Film Selection: Thinner, more flexible films reduce cracking risk. Relief Scoring: Adding micro-perfs in the coating layer only can relieve stress without affecting the substrate. Testing and Quality Control Bend Tests: Assess crack formation on sample folds before full production. High-Speed Trials: Score cracking can be magnified at higher folding speeds. Visual Standards: Establish acceptable limits for cosmetic cracking based on brand requirements. References ASTM International. (2022).
