Plastic Solutions

Our business is conceiving, engineering and manufacturing extrusion plants for the flexible packaging industry. The concrete experience in this sector allowed us to mature a deep knowledge on the production of multilayer plastic film production, too.


On the basis of this awareness, two critical points to solve come to light:

  • Winding techniques;
  • Energetic yield.

The target of Extech is solving and optimizing those aspects by exploiting the direct collaboration with our Customers in order to obtain the final result as quickly as possible.


We are pleased to present our HI-TECH LINE, designed to meet the needs of manufacturers of polymer separators for lithium-ion batteries. The choice of the arrangement of the coextrusion line with all its auxiliary components, allows us to obtain the following advantages:

  • Reliability of operation;
  • Use of an automatic thickness adjustment system ;
  • Electrical/electronic equipment located in suitable areas not subject to vibrations, and with easy access for maintenance operations;
  • Wide operational spaces ;
  • Ease of intervention for filter changes;
  • Feeding of raw materials to the hoppers with gravimetric dosing systems.

We conceive and manufacture parts for cast film lines, circular head (blow) and bi-orientation (blow).
All our products are designed and conceived to obtain optimal performances minimizing maintenance times and costs.
Thanks to our experience we can develop personalized solutions for our Clients.

The range includes:

  • Reel manipulators at line end;
  • Circular extrusion heads;
  • Pre-heating and bi-orienting tunnel;
  • Stretching groups for bi-oriented blow film.
