Services
Our capabilities are divided into three core business areas:
Properties of the films
The respective location where the composite films is determined by their chemical resistance, mechanical strength and the electrical and physical values. Our products are doing well in high-voltage machines, transformers or motors are used as in the isolation of data or power cables or as a coating or release films in almost all industrial sectors.
- Electrical Applications.
- Cable Industry.
- General Industrial Applications.

FAQ
1. What does film converting mean?
Converting is the customer specific finishing and cutting of films from standard stock: slitting to defined widths, rewinding onto suitable cores, die cutting, embossing, laminating and coating with heat activatable adhesives.
2. Which materials does Polifibra convert?
As standard, polyester (PET), aluminium and copper composites, BOPP, PVC and PE in different versions, as well as composite films with heat activatable coatings (PREPREGS).
3. In which business areas does Polifibra convert?
In three core areas: 1. electrical applications (insulation for HV machines, motors, transformers), 2. the cable industry (shielding, separating and insulating films) and 3. general industry (coating, release, sealing and battery films).
4. Which composite structures are possible?
Polifibra produces two layer and multilayer composites, for example aluminium/PET, aluminium/copper, polyester/Nomex/polyester as well as PET films with heat activatable adhesive coatings.
5. How are heat activatable coatings (PREPREGS) used?
The coating is activated under pressure and heat and bonds the film permanently to the substrate without a separate adhesive. This is standard practice in winding and laminating processes in the electrical industry.
6. Can I request customer specific film composites to drawing?
Yes. Polifibra develops and supplies film composites to specification. Layer structure, thickness, width, core type and winding hardness are agreed together with the engineering and production departments of the customer.
7. Does Polifibra provide samples before a series order?
Yes. Samples are produced on request before series release, including the agreed composite combinations and converting dimensions. This allows the film to be validated on the own line of the customer before production starts.
8. What are the advantages of an integrated film manufacturer compared with pure trading?
Shorter routes for special requirements, direct coordination with production, adjustment of layer structure and tolerances, and one contact person for technology and logistics. This matters whenever standard stock is not sufficient.
9. What are the disadvantages of pure film lamination compared with a prepreg composite?
Pure lamination uses a separate adhesive that has to be managed additionally in the process (roll length, processing window). Prepreg composites are already coated and are activated thermally, which is more stable in series production.
10. How does Polifibra support the selection of the right film?
Through direct technical consultation: the requirement profile (voltage, temperature, media resistance, bonding process) is compared with the available materials. On this basis the structure is defined and, if required, a sample is provided.
