Winding systems

Contact winder

The simplest winding principle is usually used for monofilm made of HDPE or LLPE/LDPE for simple bags or waste bags. The method is also particularly suitable for blunt films.

Central winder

The most universal winding system is suitable for both simple and complex film structures. In addition to the contact winder, the film roll is driven in a controlled manner.

Gap winder

The gap winding is a special form of central winding. Typical applications: strongly sticky films (e.g. high AVA content or ionomer on the outer layer), blunt or strongly shrinking films.
