Technology

Coveme has been converting polyester film for over 20 years and has successfully developed sophisticated technologies in the production of high-tech films. The 14 production lines installed, in the two production plants, are set up for converting processes of the Pet film such as lamination, surface treatment, heat stabilization, coating and slitting.
Our products are employed in many industry applications such as solar module protection, biosensors strips, image transfer applications, flexible printed circuitry, durable lables and tags, electrical insulation, printing systems for industry, interior design industry.
The value Coveme adds to the film is vital for our clients who, themselves, work with advanced production processes.
All our production processes can be combined according to request in order to create a fully customized product with a unique blend of added value characteristics.

Lamination

The process of lamination consists of coupling two or more layers of PET film, 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 are developed specifically depending on the end use and convey to the laminate a chemical and thermal inertia as well as resistance to hydrolysis and UV rays.

Surface treatment

Coveme performs two types of treatment: etching and chemical. Etching is a trichloroacetic acid (TCA) based treatment that modifies the molecular structure of the film surface. This treatment is usually done to “prepare” the film surface for water-based dispersion coatings, that otherwise would not adhere to a non-treated PET surface.
Chemical treatments on the other hand form a “bridge” between the polyester film surface and the coating that is added afterwards.

Increased wettability
Enhanced adhesion for
coatings, resins and adhesives
Improved bonding

Coatings

Coating is a process of spreading thin and uniform specialty layers on the film in order to add specific characteristics to its surface. Different coatings can be applied at the same time with various technologies, such as: air knife, gravure, meyer bar, multi pressure gravure or microgravure, die slot.
Coveme today offers products with ecological coatings, free off formaldehyde, chromium and phthalates that are applied in solvent-free coating processes.

Heat Stabilization

Coveme’s heat stabilization process gives the film a higher dimensional stability. This is a vital feature for clients whose manufacturing processes include temperatures higher than the transition glass temperature of PET (about 80°C). Coveme films (75 – 350 µ) have a residual shrinkage of 0,2% in MD according to ASTM D 1204.for its heat stabilized films in thickness from 75 to 350mic. Values for lower thickness are customer specific.

Higher dimensional stability
Low residual Shrinkage

Slitting

Coveme has an efficient slitting and rewinding department and guarantees for maximum traceability and efficient shipment. The process is fully automated with slitting widths ranging from 6mm to 2300mm and the possibility of customized marking and labelling.
