High tensile strength, good dimensional stability, temperature resistance typically up to approx. 150 °C (higher for short periods), good electrical insulation values and chemical resistance to oils and many solvents. The exact values depend on the specific film system.
Packaging PET is designed for food standards and low cost. Technical PET films such as those from Polifibra have tighter tolerances, higher mechanical load capacity and are specified exactly in terms of surface, thickness and thermal class.
POLI BOND is a PETP film whose surface is pre-treated on one or both sides in various degrees and which is available from 23 to 350 µm. It is used whenever the subsequent process (adhesive, lacquer, coating) requires high adhesion.
PET release films with good chemical resistance and defined mechanical properties, some of them with a release coating, suitable for separating tacky semi-finished products, prepregs or composite materials.
Coated sealing films with temperature controlled activation, which bond only once the sealing temperature is reached. This makes them suitable for reproducible industrial processes in which films are sealed in a targeted way.
Battery films are technical films (typically PET or composites) used in cell construction, module insulation or as a protective layer. High purity, defined dielectric properties and tight dimensional tolerances are essential. Polifibra explicitly supplies films for these applications.
Yes. Polifibra produces die cut parts, embossed formats, pipeline protection and spirally wound shrink tubes from its own films, including tool making in coordination with the customer.
Films with high tear strength and temperature resistance, for example as separating layers in pressing, laminating or curing processes. They do not remain in the end product but have to withstand the process temperature reliably.
Yes. Polifibra offers printing films with different surface treatments, matched to the respective printing process (screen, pad, digital and flexo printing) and to the inks used.
In the industrial portfolio, POLI BOND for example is available from 23 to 350 µm. Converting in width, core and roll length follows the requirements of the line of the customer. Special formats including die cutting and embossing operations are standard.
