Bubble double

23 June 2008


A major Israeli flexible packaging producer has installed a second Colines off-line system to expand its production of high tech air bubble film.

With the Colines system, the formation of the bubble does not take place through the extrusion of raw material pellets, but rather through the heating of a flat film in reel form which is introduced in the thermoforming cylinder and shapes the bubble.

The winder provides two-way winding (internal/external bubble with reels up to 1,200 mm diameter) and is fully automatic, including ejection of the reel. Motorized double unwinders operate for third layer lamination in continuous form with a system for cutting and recovery of edge trims.
