Evaluating Matte Film Tensile Strain Limits during High Speed Folding
Matte film lamination yields at 6 to 12 percent strain during high speed folding, causing micro-crazing that demands wider crease channels to prevent failure.
High Speed Folding Boxboard
Premium Grade
Multi ply substrate is a specific category of paperboard engineered to maintain its structural integrity during rapid conversion and filling operations. This high speed folding boxboard features a high stiffness to weight ratio and excellent dimensional stability under varying mechanical loads. It resists vibrations.
Runnability Factor
Consistent thickness and a smooth finish allow the material to pass through feeders without snagging. In the context of high speed folding boxboard, the uniformity of the moisture profile prevents the sheets from curling when they hit the heated sections of a printing press. This reliability reduces the frequency of manual interventions.
Efficiency increases.
Surface Quality
Mechanical pulp in the middle layers provides the bulk required for stiffness while chemical pulp on the outer layers offers the strength needed for folding. This layered construction enables high speed folding boxboard to achieve a clean score and a sharp bend even at thousands of units per hour. Precise coating applications ensure that the ink dries quickly and does not smear when the blanks are stacked at the end of the line.
Dusting is kept to a minimum to prevent the buildup of debris on the rollers and the printing plates. Speed defines performance.
