PETG and PCTG films
Starting at a thickness of 0.1 mm, customer-specific solutions for various applications can be realized – as roll material, cut to size or pre-assembled film. What matters is not only the material itself, but also the interplay between the thickness of the film, the surface, the temperature range, chemical resistance and later use.

What PETG and PCTG films are unique makes
PETG and PCTG are among the transparent copolymers and offer a Balanced combination of aesthetics, durability and usability. They are easy to thermoform and are therefore suitable for geometries where a flat sheet is intended to form a functional shape.
The right solution depends on many factors: How transparent must the film be? What surface is required? Does the material permanently withstand contact with cleaning agents, oils, or other media? Will the film be deep-drawn, bent, printed, laminated, or assembled?
We don’t think in standard answers, but in possibilities.
Transparency and high-quality optics
PETG and PCTG films can offer a clear, high-quality and uniform appearance. This makes them interesting for applications where content remains visible, products are presented, or the surface is part of the product quality.
Depending on the type and processing, different surface finishes are possible. From smooth and glossy to matte, textured or embossed, we create foil solutions that not only function but also complement your product aesthetically.
Thermoformability
PETG and PCTG films can be thermoformed under suitable conditions. This results in shells, covers, trays, inserts or customer-specific geometries being created from the flat film.
This requires uniform heating, the correct tool design and coordinated process control. Film thickness, mold depth, radii and desired dimensional accuracy must be considered together to ensure that the finished mold functions reliably.
High durability
Where films are not brittle enough to break or quickly deteriorate during processing, PETG and PCTG films provide a robust material base. The toughness supports applications where the film is subjected to mechanical stress, shaped, transported, or further processed.
Which configuration is best depends on the specific load and the temperature range. We will work with you to determine which material type offers the necessary safety for your application.
Chemical resistance
In many applications, films containing cleaning agents, disinfectants, oils, fats, or other media come into contact with them. PETG and PCTG films offer good chemical resistance depending on the type, making them interesting for demanding environments.
The actual durability always depends on the medium, the concentration, the exposure time, the temperature, and the mechanical stress. Therefore, we not only consider a data sheet, but also the conditions under which your film will be used later.
Temperature range
PETG and PCTG films can be used and processed within a defined temperature range. The temperature limits that apply depend on the respective material type, film thickness, shaping, and subsequent use.
For selection, both short-term temperature peaks and the permanent operating temperature are relevant. Temperature changes, contact media, and mechanical loads can also influence the material properties. We help you realistically determine the required temperature range and select the appropriate film.
BPA-free material types
PETG and PCTG types free of BPA are available for applications with special requirements regarding material purity and product safety. The required approvals and compliances depend on the intended use and the direct contact with the respective product.
Especially in medical and food applications, material, processing, cleaning, and the operating environment must all be considered together. We help you find the appropriate material base for your product.
Which PETG or PCTG film Does it suit you?
Not every application needs the same film. We think about the later use and together we examine which combination of material type, film thickness, surface and processing suits your requirements.

Packaging technology
PETG and PCTG films are suitable for packaging where transparency, formability and high-quality presentation are all important factors. The film is used to create trays, blisters, inserts and covers that make products visible while also protecting them.
Equipment and product technology
Transparent or structured films can be used as a cover, a viewing window, a protective film, or a mold component in devices and technical products. The surface can then be adapted to suit the function and the desired appearance of the product.
Displays and visibility components
Where content needs to remain visible and the surface still needs to be protected, PETG and PCTG films offer a versatile solution. Depending on the design, transparent, matte or textured surfaces are possible.
Transport and protection systems
Thermoformable films can be used for inserts, trays, and protective packaging. The geometry is adapted to the product, ensuring that sensitive components can be safely received, transported, and delivered.
Why Filzwieser for PETG and PCTG films?
A film is not just a roll of material. Their quality is evident in their later use: in the shaping process, in the surface finish, in cleaning, in contact with media, and in reliable processing.
We combine material expertise with experience in film extrusion and work on the entire solution together. Together, we examine whether PETG or PCTG is the better base, what film thickness is required, which surface is suitable, and whether roll stock, cut-to-size or a pre-configured solution is a sensible option.
This results in a solution that fits your product and process, rather than a standard film.
