For a robust and durable product

Technical Approach

In high-frequency welding, plastic films are welded together. In this way, we join PVC plastic films together for you, giving them a particularly stable and robust shape. The PVC products are mostly screen-printed.

Overview of Benefits

  • Beautiful edges, round corners and spine joints with book covers made of PVC
  • PVC folders get the necessary stability thanks to an inserted cardboard blank
  • PVC products are water and dirt repellent and therefore also suitable for use in workshops and when travelling or for permanent use as a school book or reference book
  • We process phthalate-free and REACH-compliant plastic films
  • Further finishes are possible; for example, with hot foil, UV varnish or blind embossing.
