IF subsidiary Sinea has bought an MRS extruder from Gneuss for the production of PET sheets to be used for food packaging.
The equipment will allow Sinea to process mixed reclaim material from the washing line directly into a uniform sheet. MRS technology removes all residual moisture, guaranteeing a consistent end product.
Melted polymer flows into a large single screw drum that contains eight small extruder barrels, parallel to the main screw axis. Unmatched devolatilising performance can be achieved due to the constantly renewed polymer surface so that undried and uncrystallised PET bottle flakes can be processed directly.
As the MRS decontaminates the polymer efficiently, the US Food and Drug Administration (FDA) gave it a letter of no objection for direct food contact made out of 100% post-consumer PET bottle flakes.
Sinea vice president Sergio Bravo said that with the new MRS extrusion system in place, the company is able to produce different sheet formats, giving it the ability to be more flexible.
"One of the best features is the high level of transparency, especially appreciated by customers making thermoformed packaging products for supermarket shelves," Bravo added.
Gneuss previously installed its filtration system into Sinea's first sheet line. Sinea manufactures caps for soft drinks and polypropylene woven sacks for different industrial applications. The company has sites in Argentina, Colombia, Chile and Peru.
