Inline Acoustic Time of Flight Profiling for High Speed Folder Gluer Score Verification
Inline acoustic time-of-flight profiling maps internal board ply delamination at line speed, preventing cartoner jams without marking finished carton surfaces.
Non Destructive Laser Thermoelastic Acoustic Wave Mapping of Micro Delamination Dynamics in High Speed Barrier Fold Scores
Non destructive laser thermoelastic mapping measures subsurface micro delamination dynamics in high speed barrier board scores without damaging surface coatings.
Optimizing Matrix Channel Dimensions for Recycled Content Folding Boxboard Conversion
Recycled folding boxboard requires expanding matrix channel width from 1.5 to 1.8 times caliper plus rule thickness to prevent top-liner rupture.
Dynamic Z Direction Tensile Stress Propagation in Recycled Fibers during High Speed Creasing
High speed creasing generates Z-direction tensile stress waves that fracture short recycled fibers unless matrix clearance absorbs elastic strain energy.
High Frequency Acoustic Profiling for Multilayer Board Barrier Integrity
Inline high-frequency acoustic profiling measures micro-scale barrier delamination and polymer layer thickness across dynamic paperboard converting webs.
Quantifying Structural Flexural Modulus Loss in Recycled Paperboard Subjected to Dual-Axis Mechanical Decurling and Fluid Rehydration
Mechanical decurling and fluid rehydration permanently degrade recycled paperboard flexural modulus by shear micro-delamination and fiber plasticization.
Quantifying Micro-Delamination Shear Planes in Recycled Multiply Board under High Dynamic Strain Rates
Quantifying dynamic shear planes in recycled board requires high-rate impact testing to prevent score line splitting on high-speed converting lines.
Evaluating Fiber Swell and Compression Decay in Humid Paperboard Packaging
Paperboard loses up to sixty percent of top-load compression strength in high humidity due to transverse fiber swell and mechano-sorptive creep decay.
