Know-how
Polystyrene films for precise thermoformed parts.
Since 1980, STF Thermoform-Folien GmbH has manufactured customised thermoforming films and sheets made from polystyrene in Aicha vorm Wald. Colour, thickness, surface and material composition are individually matched to customer requirements.
Since 1980 Experience in film extrusion

PS Polystyrene films and sheets for thermoforming
Service profile
Customised films and sheets for industrial applications.
STF combines extrusion know-how, material understanding and personal consulting. This results in polystyrene semi-finished products matched to the application, process and required properties.
Specification
Individually configured to customer requirements
Colour, thickness, surface and material composition are matched to the application and the downstream thermoforming process.Circularity
Virgin material and recyclates
Depending on requirements, virgin material or regrind is used. The products are fully recyclable.Service
Consulting through to contract reprocessing
Personal support, individual solution development and the reuse of single-grade separated film residues are part of the service scope.Material & process
Quality is created by the right combination of material, formulation and surface.
Polystyrene thermoforming films and sheets are manufactured to customer requirements: from defined thickness and colour through machine-smooth surfaces to antistatic finish, UV stability or electrical conductivity.
Material selection Virgin material or regrind is selected to match the application area and the required appearance.
Product properties Additives such as antistatic finish, UV stability or electrical conductivity extend the application range.
Processing Films are available in mono- and coextrusion; sheets are available as monoextrusion.
Industries & applications
From workpiece carriers to propagation trays.
The products are used in numerous industrial sectors. The decisive factor is the combination of formable polystyrene quality, defined material quality and customer-specific design.
Mechanical and equipment engineering
Transport pallets, workpiece carriers, housings, covers, and cardboard and KLT inserts.
Automotive
Trays, workpiece carriers, housings, covers, pallets and inserts for industrial process chains.
Electrical industry
Cladding and housings where formability, material quality and defined properties are combined.
Horticultural industry
Propagation trays as well as disposable and reusable trays for robust, functional applications.
Furniture industry
Drawer inserts and cladding with application-specific colour, thickness and surface finish.

Process
From requirements to recyclable film.
STF develops the extrusion solution from the perspective of the later application and combines individual product development with circular economy principles.
- 01
Clarify requirements
Application, thermoforming process, colour, thickness, surface and required material properties are jointly assessed.
- 02
Define material structure
Depending on requirements, virgin material, regrind, additives and the version are selected to suit the later function of the film or sheet.
- 03
Extrude
In Aicha vorm Wald, polystyrene films and sheets with consistent material quality are produced on three extrusion lines.
- 04
Consider the circular process
Single-grade separated film residues can be returned to the material cycle through contract reprocessing.
