Technology

The most demanding applications require a precise blend of characteristics—dimensional stability, surface energy control, thermal and chemical resistance, printability, release behavior, dielectric performance, or tactile finishes—combined with the ability to reproduce these properties reliably at industrial scale.
Coveme’s production technologies play a strategic role at the start of new industrial partnerships and solutions. When manufacturers explore new surfaces, electronics architectures, or more sustainable solutions, materials define what is possible. By combining deep polymer conversion know-how with a broad technology portfolio—and by working closely with customers from concept to industrial scale-up—Coveme acts as a partner in innovation.
Our strength lies in combining multiple technologies within tightly controlled manufacturing flows, processing base materials such as PET, polyimide, metals, polymers, and papers in thicknesses from 12 µm to 500 µm and web widths up to 2250 mm.

Lamination

Roll-to-toll process of coupling two or more layers of PET film, polyimide, metals, polymers or other special materials and papers. The single layers are bonded in order to obtain a multi-layer laminate that sums the vital characteristics of each single material. The adhesives used for the lamination in combination with material properties convey to the laminate a chemical and thermal inertia as well as resistance to hydrolysis and UV rays. Multilayer thickness range 23µ - 890µm, web width up to 1850mm

Surface treatment

Treatments of the film surface with various technologies. Among these TCA (Trichloroacetic acid) that elevates the surface tension up to 72 dynes/cm. This guarantees an excellent wettability and therefore maximum adhesion with water and solvent based coatings and 100% solid radiation cured coatings.

ELEVATED SURFACE TENSION UP TO 72/DYNES
EXCELLENT WETTABILITY
MAXIMUM ADHESION WITH VARIOUS COATINGS

Functional Coatings

Different coatings can be applied at the same time by spreading a thin and uniform specialty layer on the film with the most appropriate technology among air knife, gravure, Mayer bar and die slot. The curing is carried out with dryer technology and radiation by UV and E-beam.

Heat Stabilization

Heat stabilization process of plain, treated and functionalized PET that gives the film a higher dimensional stability. This is a vital feature for clients whose manufacturing processes include temperatures higher than the transition glass transition temperature (𝑇𝑔) of PET (typically between 70°C and 80°C). Maximum residual shrinkage of 0,2% in MD @150°C/30min according to ASTM D1204 standard. Values for lower thickness are customer specific. Thickness range 75 – 350 µm, maximum web width 2200mm
