Hi-performance 5 layer Barrierblown®

A new BARRIERBLOWN® line with a web width of 1700 mm has recently started at B-PACK® the production of a 5-layer coextruded barrier film. This new machinery boasts higher performances than the previous ones, and is also equipped with thickness measuring system and a corona treatment station. The feedback provided by B-PACK®, producing barrier film up to seven layers, is one of the most precious factors of the significant experience acquired by COLINES® in the blown technology. The minimum thickness of the film produced is of 24 micron with sigma ± 0,7, with a central barrier layer of 3 micron of EVOH, suitable for food packaging as well as medical applications. The net hourly throughput is of 400 kg/h.
