EFSA/FDA Certified Twin Screw Technology from Reifenhäuser.
Reliably Documented
If recycled materials come into direct contact with food, they require special certification from the European Food and Safety Authority (EFSA). Reifenhäuser Cast Sheet Coating has developed a solution for the production of recycled PET film using a twin-screw extruder and high-performance vacuum system that meets the high requirements of the EFSA. The advantage: with the certified process, recycled PET material can be processed directly without pre-treatment or pre-drying in an additional reactor - as is necessary with other processes. This saves processors from having to invest in an additional system component and avoids additional energy and maintenance costs.
1
EFSA certification
Value PET- lines are EFSA compliant by the co-rotating twin screw and the high performance vacuum system. Reifenhäuser Cast Sheet Coating supports customers during the certification process with the relevant authorities. This includes the upstream cleaning process of the ground material as well as quality monitoring of the feed material and production under the criteria defined by EFSA.

Quality monitoring of feed material
For PET recycling material a established system exists since many years where quality characteristics have already been defined for further processing - for example, the extent to which the material has been cleaned. PCR bottle flake recycled in Europe meets already defined standards in most cases. This simplifies monitoring within production.

Cleaning with defined parameters
The key to the EFSA-compliant processing of PET bottle flake into PET sheet is the Value PET line with twin-screw extruder and high-performance vacuum pump. The line configuration allows the melt to be cleaned under defined - and therefore reproducible - parameters directly in the process. In other words, sheet producers do not need to invest into an additional upstream cleaning and drying process, that would otherwise increase the space, energy and cooling systems required for the line. Product changes can be carried out quickly and easily.

Storing production parameters for verification
For EFSA audits, recipe- and product-related data of the certified process must be stored for several years. The ExtrusionOS Production Compliance software bundle helps to monitor and securely document production processes and compliance with EFSA-relevant thresholds in a data-based and real-time manner. A live dashboard provides transparency on ongoing production and its thresholds, enabling much faster action (see animation). In addition, a reel log stored in ExtrusionOS can be transferred to a digital product passport - for example, according to the open R-Cycle-Standard. ExtrusionOS Production Compliance is based on the connectivity solution ExtrusionOS Core & c.Hub Middleware and can be retrofitted to existing lines.
Product quality is crucial, especially when it comes to films that come into direct contact with food! Trust in a reliable documentation of your quality data and save resources at the same time! With ExtrusionOS, you can document your production parameters digitally, provide reliable proof of conformity and create roll reports for your customers. The EFSA Cockpit shows you all important quality parameters in real time and sents alerts if necessary.
