Fourth layer unwinder
Fourth layer unwinder
This unit laminates a 4th layer film (HDPE film, PE-foam, coated aluminium foil or kraft paper, printed film, non-woven, etc.) to the base of the air bubble film, improving or varying the finished film’s aesthetic and/or mechanical characteristics. It consists of a double-station unwinder equipped with two air expansion shafts for loading the 4th layer film rolls. While a roll is unwinding on one station, a new roll can be prepared in stand-by on the other for a no-stop changeover. This modular unit is easily retrofitted to any new or existing in-line air bubble film plant.
IMPORTANT: The technical data listed below has been CERTIFIED by analyzing CONTINUOUS line operation over a period of 24 hours, with no unexpected stops!
