Surface Energy Shift and Gloss Drift under Friction Sled Cycles
Friction sled cycles strip migratory slip agents, elevating polar surface energy while generating micro-roughness that causes severe specular gloss drift.
PTFE Modified Wax
Chemical Lubricant
Surface modification of printing inks and coatings prevents mechanical scuffing during high-speed packaging operations. The use of ptfe modified wax provides a durable, low-friction surface by blending polytetrafluoroethylene particles with polyethylene or microcrystalline waxes. This combination improves the rub resistance of the printed substrate.
Abrasion Resistance
During the drying phase of the ink, the wax particles migrate to the surface to form a protective layer that resists rubbing and scratching. The addition of the polytetrafluoroethylene polymer enhances this effect, providing a lower coefficient of friction than standard waxes alone. This protective layer allows the printed carton to survive the high friction forces of automated packaging lines, preventing cosmetic damage to the printed graphics.
This treatment is especially valuable for matte finishes.
Ink Formulation
Inclusion of this additive in water-based or energy-cured coatings requires careful dispersion to ensure that the particles remain evenly suspended in the liquid matrix. Printers adjust the dosage based on the required slide angle and the specific rub test standards of the brand owner. An incorrect concentration can cause the surface to be either too slippery, which makes carton gluing difficult, or too abrasive, which leads to scuffing during shipping.
Consistent application of this modified wax protects the visual quality of the carton from the folder-gluer to the consumer shelf.
