HDPE Laminated Collapsible Tubes

Abstract

A typical Lamitube is a 5 layer structure with aluminium foil in the middle layer and polyethylene as an inner and outer layer. The Aluminium foil layer is bonded with polyethylene using adhesive/tie layer. A lamitube is made using a 5-ply structure with overall thickness ranging from 210 to 290 micron based on the final application. The film is printed and slit to the required tube diameter generally ranging from (22mm-35mm) and converted into a Sleeve by sealing online. The Sleeve is then moved over a conveyor and goes to the molding station where the Shoulder (HDPE) of the tube is formed.
