COEX BUBBLE (10)™
COEX BUBBLE (10)™ - high-speed/high-output, in-line co-extrusion
The world’s largest packing corporations use the COEX BUBBLE (10) as it represents the most advanced technology for in-line production of air bubble films containing an integrated air retention barrier.
The COEX BUBBLE (10) is a cast co-extrusion system with three extruders. It processes LDPE, TIE and Nylon-PA6 pellets to produce high-performance, symmetrically structured (ABCBA+ABCBA), multilayer air bubble film. The 10-layer structure allows for integration of an air-tight, Nylon-PA6 barrier for longer bubble-air-retention, thus improving the film's cushioning and protective properties, even at reduced thicknesses. For example, a 35 g/m2 of coex film has the same resistance of a 60 g/m2 mono film—a definite competitive advantage!
Especially suitable for technical packaging and envelopes, the COEX BUBBLE (10) series is fully automatic and includes touch screen controls for custom configuration of production recipes. Thanks to an on-board network connection, plant function can be remotely monitored via internet. The modular configuration of COEX BUBBLE (10) lends itself to many useful upgrades, such as a 3rd layer lamination unit, a perforation unit, etc...
