Significantly improve ink adhesion: Low surface energy materials such as PP/PE (<30 dynes) are increased to 38-44 dynes, introducing polar groups such as hydroxyl and carbonyl groups to form chemical bonds and mechanical interlocking in the ink, preventing color fading and delamination.
Improving printing adaptability and uniformity: optimizing surface wettability, reducing ink shrinkage and edge blurring, ensuring transfer uniformity and color reproduction of high-precision color printing (such as food labels).
Dry and environmentally friendly with no chemical residues: no solvents or water washing required, only producing trace amounts of ozone that can be ventilated, in compliance with food packaging and green manufacturing standards.
Efficient and low-cost adaptation for mass production: can be integrated online into printing machines, with a processing speed of up to 100 meters per minute; The device has a simple structure, low energy consumption, minimal maintenance, and does not damage the strength and transparency of the film body.
