Why protective films?

01 — Features
/01

Electrical insulation

Lexan, Palsun, Formex, Nomex and Mylar materials for electrical engineering requirements.

/02

Precise cutting

Even complex shapes to tight tolerances — including folds.

/03

Wide material range

Insulation materials, foams, rubbers and tapes from one partner — material combinations also possible.

/04

Fast series

Rapid prototypes, flexible volumes from three units.

/05

Plastic folding

Exceptional specialist skill: folds and corners directly in sheet material — three-dimensional insulation without molds.

From material to product

02 — Structure
01
Material selection
Lexan, Palsun, Formex, Nomex, Mylar, Kapton, foams and rubbers to requirements.
02
Design
From CAD data to cutting file.
03
Printing
Screen or digital printing with the customer's graphics.
04
Die cutting and cutting
Cutting with the suitable method to tight tolerance.
05
Bending and forming
Scoring, folding and bending for three-dimensional shapes.
06
Adhesive coating
Adhesive surface on the product as the customer requires.
07
Packing
Packed in series, as kits or in installation order.

In insulation the material decides: dielectric strength, heat resistance and mechanical durability are dimensioned to the standards and the application.

The structure is always defined by the application together with the customer's product development — we help with material choices already at the design stage.

Ask an expert →
Which materials can protective films be made from?

The material range is broad and the choice always depends on the application — temperature, chemicals, UV exposure and the mounting surface decide. Our expert proposes the most suitable options based on a drawing or a description of the application.

What series sizes do you manufacture?

From single prototypes to large volume series. Digital methods make small batches possible without tooling costs; series production is scaled to need.

Can I get a sample or a prototype before ordering?

Yes — we make prototypes and zero series for approval before tooling investments and the start of series production.

How fast do you deliver?

Delivery time depends on the product and series size. Prototypes and series production on the agreed schedule — buffer stocks secure continuous availability.
