Corona Treatment of Narrow Web

LabelTEC product description

The purpose of surface treatment of polymer-based materials is to increase surface wettability through electrical discharge.

The low surface energy of polymerbased substrates often leads to poor adhesion of inks, glues and coatings.

To obtain optimum adhesion, it is necessary to increase the surface energy of the substrate to just above that of the material to be applied.

Surface treatment with Corona results in improved surface adhesion properties.

LabelTEC is designed for the pretreatment of conductive and nonconductive narrow webs.

This type of system will treat either one or both sides of the web and will accommodate
widths from 100-500 mm, running at production speeds of up to 150 m/min.

FAQ

What is LabelTEC used for?

LabelTEC is used for corona treatment of conductive and non-conductive narrow webs before printing, coating, gluing or laminating.

Why is surface treatment needed on narrow web materials?

Many polymer-based substrates have low surface energy, which can make it difficult for inks, glues and coatings to bond properly.

How does LabelTEC improve adhesion?

LabelTEC increases the surface wettability of the substrate, creating better conditions for reliable adhesion of inks, glues and coatings.

Can LabelTEC treat both sides of the web?

Yes. LabelTEC can be configured for treatment of one or both sides of the web, depending on the production setup.

How fast can LabelTEC run?

LabelTEC can run at production speeds of up to 150 m/min, depending on the material and process requirements

What type of electrodes does LabelTEC use?

LabelTEC uses ceramic electrodes for controlled and reliable corona treatment.

Is LabelTEC an environmentally friendly solution?

Yes. Corona treatment is a dry electrical process that can reduce the need for chemical primers or additional pre-treatment where the application allows it.

Is LabelTEC available as a standard or customized solution?

Yes. LabelTEC can be configured to match your narrow web material, treatment width, line speed, power requirement and whether one or both sides need treatment.
