Double and Triple Bubble line

Double and triple bubble extrusion lines are used to produce biaxially oriented plastic films. Material is stretched in machine in a transversal direction simultaneously. This processe delivers a molecule orientation in both axes, and this enhances many of their properties. Typical applications are shrink and barrier packaging, casing film, and high barrier film packaging. In case a barrier layer is required this may be based on Pvdc or Evoh.
