What flame-retardant films unique makes
Flame protection is achieved through the targeted selection of the base polymer, suitable additives, and a film structure tailored to the application. The key is that the thinner the film is, the more precise the material, processing, and testing requirements must be. Therefore, we consider not only the desired flame class, but also the overall function of the film in the later system.
Defined combustion behavior
Flame-retardant films are designed for applications where a fire should be as difficult to ignite as possible and not spread uncontrollably. Depending on the material and design, the film can affect the burning behavior, make ignition more difficult, or self-extinguish after removing the ignition source. The required testing and classification depend on the standard, application area, and product function.
Safety without unnecessary restrictions
Flame protection must not automatically mean that the film becomes brittle, difficult to process or visually unusable. The right material selection creates a balanced ratio between fire protection, flexibility, mechanical durability and surface quality. This results in films that not only meet a requirement, but also function reliably in use.
Halogen-free solutions
Depending on the application environment, halogen-free films can be a useful alternative. They are interesting where smoke formation, the corrosivity of combustion gases, or specific requirements regarding the material composition play a role. Whether a halogen-free version is necessary or technically advisable is determined based on the specific product and its environment.
Temperature and media resistance
Technical films often have to withstand more than just a brief contact with a flame. Heat, moisture, oils, cleaning agents, electrical loads, or mechanical stress all affect the material during its entire lifespan. Therefore, when selecting materials, we also take into account the maximum operating temperature, temperature changes, and resistance to relevant media.
Surface quality and processing
Flame retardant additives can affect the flow behavior, surface finish and processing of a film. For visible applications, a uniform surface finish, defined appearance and stable film quality are crucial. Depending on the need, the film can be supplied as a roll, cut to size or as a processed solution.
What flame-resistant film Does it suit you?
Not every application needs the same film. Among other things, the desired fire protection, the thickness of the film, the mechanical load, the temperature, the surface area and the further processing step are crucial. We think about the application situation and together find the film construction that really suits it.
Flame-resistant PET-G film
PET-G films are suitable for applications where a high-quality surface, good formability and reliable processing are required. In flame-resistant versions, they can be interesting for technical coatings, protective films and visible component surfaces – depending on type, thickness and required testing.
- Good surface quality
- suitable for visible and technical applications
- reusable through cutting or reshaping, depending on the design
- flame-proof types available for specific requirements
Flame-resistant TPU film
TPU combines elasticity with mechanical durability. Flame-resistant TPU films are interesting where the film must adapt, move, or remain permanently flexible. Depending on the type, flexibility, abrasion resistance, and durability can be tailored specifically to the application area.
- flexible and adaptable
- good mechanical load-bearing capacity
- interesting for protective, covering and insulating applications
- suitable for individual foil constructions and further processing
Flame-resistant polyamide film
Polyamide films are suitable where temperature resistance, strength and technical durability are required. A flame-resistant version can be developed for demanding applications in electrical, energy and industrial engineering, provided the material, film thickness and processing meet the required function.
- high mechanical strength
- Good temperature and media resistance, depending on the type
- suitable for demanding technical applications
- compatible with other layers in multi-layer structures
Flame-resistant multilayer film
If a single material layer does not fully meet the requirements, a multi-layer structure can be the better solution. Different layers perform different functions: flame protection, mechanical stability, flexibility, electrical function, surface quality or processability.
- Combination of several material properties
- Targeted coordination of function and surface
- suitable for complex technical requirements
- individual design of material and layer structure

Why Filzwieser for Flame-retardant films?
Flame-resistant films place particular demands on material selection, the extrusion process, and further processing. Additives can affect the flow behavior, surface finish and flexibility. At the same time, the film should be uniformly, dimensionally stable and reliably processable. Depending on the application, additional requirements regarding layer structure, electrical insulation, temperature resistance or further processing also apply.
That’s where we come in. We don’t view the film in isolation, but as part of your product and your system. From the initial idea to the mass production, we examine which material, structure, and processing method is best suited for your application. This results in technical films that not only pass testing but also function reliably in daily use.

Frequently asked questions
What does „flame-proof“ mean for films?
Flame-resistant films are designed so that they ignites more difficult under defined conditions, burns out more slowly, or self-extinguishes after removing the ignition source. The fire behavior is evaluated through appropriate testing procedures. The classification required depends on the application, the product design, and the applicable standards.
How is flame protection achieved in a film?
The flame retardant can be applied through the The selection of a suitable base polymer, special additives or a coordinated multi-layer structure is achieved. However, the components used not only influence the fire behavior but also flexibility, surface finish, strength, color and processing. Therefore, the material selection must always be made in conjunction with the overall application.
Are flame-retardant films also available without halogen?
Depending on the material and the desired classification, halogen-free solutions can be tested. They are particularly interesting when requirements regarding smoke development, flame gases or the material composition apply. Whether a halogen-free film is suitable for your product depends on the required testing and the further technical specifications.
Which film is the right one for my application?
This depends on several factors: the desired burning behavior, film thickness, temperature, mechanical stress, flexibility, surface finish, electrical function, and further processing. The question of whether roll stock, cut-to-size or a pre-assembled solution is required is also crucial. We help you organize the requirements and find the appropriate structure for the slides.
Can flame-resistant films be recycled?
Yes, depending on the material and design, flame-resistant films can be used. cut to size, reshaped, laminated or otherwise assembled. The processing temperatures, the behavior of the film, and the effects of the processing step on the required properties must be taken into account. Timely coordination creates certainty in this regard.
