PET film/sheet lines retrofitted with Kreyenborg’s recycling unit

A PET film or sheet line can be retrofitted with an IR-CLEAN system made by Kreyenborg GmbH & Co. KG from Germany, without any time and efforts for reconstruction. Suitability for food production of the semi-finished products and optimization of the production line’s performance are both guaranteed.

Recently, these features have convinced two manufacturers of PET thermoformed trays for foodstuff in South America, who have opted for these ‘Add-on’ modules from Germany for a total of three production lines of a throughput of more than 1,000 kg/h respectively.

Now, these plastics processing companies are able to process up to 100% of recycling PET ware and operate on the packaging market with high-quality solutions suitable for food production applications.

A PET film or sheet line can be retrofitted with an IR-CLEAN system without any time and efforts for reconstruction.

A high decontamination output, FDA and EFSA approvals, a simple and a both energy-efficient and performing process control as well as reduced assembly space make the IR-CLEAN an additional component for every PET line. Having accomplished a reiterated process optimization and an additional challenge test, Kreyenborg has succeeded in increasing the decontamination performance.

Recycling material that has been treated in the IR-CLEAN may be used at 100% for the production of any kind of food packaging (storage for 365 days at room temperature).

Both sheet manufacturers located in South America use their own, shredded in-house edge-trim produced in the thermoforming process on the one hand and additionally bought post-consumer recycling material on the other hand. The material is conveyed into the metering hopper of the IR-CLEAN unit and flows into the rotary drum through a volumetric metering system. At this point, the welded continuous screw spiral guarantees a homogeneous flow of the material with a pre-defined residence time (first-in / first-out principle).

Recycling material that has been treated in the IR-CLEAN may be used at 100% for the production of food packaging.

Due to the constant rotation of the rotary drum and the mixing elements incorporated in the screw flights, the material is stirred continuously and its surface is at the same time revolved on a permanent basis.

The Infra-red module installed above the material bed heats the material up to a high temperature level quickly and immediately, while a constant air flow extracts the air loaded with humidity and other contamination particles. This entire process is completed within a few minutes only. The recycling material then prepared is directly conveyed into the existing extrusion line.

Neither any other kind of machine component nor any other kind of material treatment is required to process the recycling material for PET sheet to be used in food packaging.
