Corona treatment machinery better adhesion and sharp printing

Corona treatment machines are essential in processing plastic films. Corona treatment modifies the film’s surface tension, improving the adhesion of inks, coatings, and laminations, and ensuring sharper, more durable printing. Essential for packaging, bags, and technical films, this process delivers superior quality and reduces scrap.

Why Choose Corona Treatment

The surface of PE, PP, or PET films has low surface energy, hindering adhesion. Corona treatment creates micro-level molecular changes that increase wettability:

Sharper Printing

Ink penetrates more effectively into the micro-channels created by the electrical discharge, reducing the risk of smearing and loss of definition.

Laminate Adhesion

For laminated films, a corona-treated layer ensures the stability and strength of the final product, minimizing the risk of delamination.

Compatibility with Different Materials

Corona treatment machines can process films in PE, PP, PET, PVC, bioplastics, and other polymers, provided the correct parameters are set (voltage, electrode distance, web speed).

Key Components of Corona Treatment Machines

Power supply: converts electrical energy into high voltage.
Treatment station: electrodes and rollers ensure a uniform discharge.
Discharge roll: protects the film during the process.
Control panel: controls power, speed, and pressure.

Superior Print Quality

Stable inks and vibrant colors, with less smudging and better adhesion.

Waste Reduction

By eliminating defects related to poor adhesion, the production of non-conforming material is limited.

Greater Versatility

The same film can be intended for different uses—from printing to packaging—simply by varying the degree of surface treatment, effectively broadening the range of applications.

Enhancement of Company Image

The ability to deliver high-quality products, color consistency, and precise finishes enhances the supplier’s reputation in the market, in terms of both reliability and technical expertise.
