Industry

Most people are known plastic films to protect food in the household. The POLIFIBRA films GmbH manufactures and assembles polyester and laminated films, which are used because of specific character in different industrial manufacturing sectors.

Films for coating

POLIFIBRA provides polyester films with different strongly adhering surfaces.

In our product POLI BOND the surface of the PETP film on or treated on both sides in varying degrees. This can be a very significant improvement in the adhesion of coatings to be achieved.

POLI BOND can in the film thicknesses 23µ - 350µ are delivered.

Films for printing

Different printings require different surfaces. In addition to highly transparent or colored opaque base films we offer here at various coatings that allow easy and quick editing.

Films for seals

Seal foils are coated films, the above-defined temperature ranges enable an activation of the coating so as to allow bonding of different products.

POLIFIBRA films offers solutions for different temperature ranges and applications.

Auxiliary materials in production

As auxiliary materials in the production are particularly polyester films or composite films with high tear strength and high thermal stresses.

release films

The good chemical resistance of polyester films as a release film enables use in various fields. Here, the smooth and uniform surface and excellent mech. Self sheep of the polyester film is very important. Mostly, however, the separation characteristics must be increased by a special release coating.

POLIFIBRA films also here on the respective application coordinated resources.

Special composites offer here also extremely high tensile strengths.

different materials

In addition to these areas of application of our films, find POLIFIBRA products even more application possibilities in the industrial sector:
  • Hoses for batteries
  • stampings
  • Embossed film formats
  • Protection for pipelines (in different forms of delivery)
  • Wound shrink tubes with very thin walls and precise inside diameters.
  • and much more.
Just contact us and we will help you to find the best solution for your application.

FAQ

1. Which technical properties does technical PET film have?

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.

2. What is the difference between packaging PET and technical PET film?

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.

3. What does POLI BOND film do?

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.

4. Which release films are offered for industry?

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.

5. Which sealing films does Polifibra have in its range?

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.

6. What are battery films and which requirements apply?

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.

7. Are customer specific die cut parts and embossed formats possible?

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.

8. Which films are recommended as auxiliary and process materials?

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.

9. Can films be pre-treated for printers and printing applications?

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.

10. Which film thicknesses and converting dimensions are available?

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.
