In the last few days, a complete co-extrusion line for the production of PET sheet has been tested at Union headquarters in San Vittore Olona.
The line, which will be delivered to European market, is composed of the revolutionary and proven twin-screw ZP 112/52 D with 4 ventings and the solid single-screw TR 90/44 D in co-extrusion. It is able to produce multilayer sheet type A-B-A to be thermoformed in various food-grade trays.
The co-extrusion line is designed to be fed with 100% PET post-consume bottle flakes without compromise in the quality of sheets achieved, which results in similar transparency and brightness as compared to the sheets made of virgin material.
The line has hourly output of 1700 kg, useful width of 1600 mm with sheet thickness adjustable from 130 to 1800 µ.
