New Generation of PET Thermoforming Sheet Lines
Reifenhäuser Combines Improved Components
In 2013, Reifenhäuser introduced the high-performance extrusion lines for PET thermoforming sheets with the patented mechatronic polishing stacks of the MIREX-MT-V design series. Now Reifenhäuser introduces the next generation of this line type.
As in the past, the heart of these lines is the tried-and-tested synchronous “REItruder” twin-screw extruders, which are now in their third generation. In combination with dry-running high-performance vacuum pumps that work with an operating pressure of 5 mbar, and the degassing units on the REItruder that have continuously been optimized through the years, the systems meet the FDA requirements (N.O.L for Recycled Plastics #209) for films that are made of 100% recycled PET and are in direct contact with food. All required declarations confirming the line technology's compliance with EFSA requirements are provided; the user is responsible for applying for the appropriate EFSA approval.
"Plug and Play" or Adjustable Systems
Depending on the customer's requirements, various different coextrusion feedblocks are available from Reifenhäuser EDS, the youngest member of the Reifenhäuser Group. The customers have frequently expressed their desire for simple (quasi “plug and play”) production. To meet this need, feedblocks are now available both for fixed layer geometries and for the tried-and-tested and highly flexible REIcofeed 2.1 systems that can be configured during operation.
Additionally, completely modernized dies are available in the wide product portfolio of Reifenhäuser EDS. For example, the producer can choose between internal deckling for maximum flexibility in the film width, or a lip gap that can be configured during operation for fast thickness changes, as well as between manual or automatic operation with thermal expansion bolts.
After 5 years of successful worldwide use, the MIREX-MT-V high-performance polishing stack has also been fundamentally modernized. Depending on the system capacity, it has 3 or 4 polishing rolls. Additionally, an axis crossing for the first roll is available optionally, for the production of thin films with large widths.
Prepared for the Implementation of Industry 4.0 Functions
The entire line has been prepared for the implementation of Industry 4.0 functions that are being developed group-wide by Reifenhäuser Digital. Thanks to the modular concept, the customers can decide individually which functionalities benefit their business activities and which are not needed (for the time being). The tailor-made solutions for individual needs are part of the portfolio of Reifenhäuser CSC, from “as simple as possible” to convenient fully automated solutions.
