Tandem Extrusion Coating & Laminating Machine for Aseptic Packaging, Beverage Cartons

Introduction:

Our aseptic packaging extrusion laminating line is used to produce such a complex paper board / aluminum foil composited sheet in a high performance and high speed process. The line is equipped with 3 set of multi-layer co-extrusion systems and automatic-adjust T die, capable of running PE、PP、EVA、EAA、EMA coating grade polymers. Fully automatic turret unwinder and winder, corona or flame treatment are available for best converting efficiency. The standard product width is from 700-1350mm and the line speed is 300mpm. The control of the complete line is integrated by PLC system and HMI. We provide customers with individual requirements to best meet the market need.

Aseptic packaging is a composited sheet of paper, polyethylene polymer and aluminum foil. The sheet structure has their unique functions from outside to inside: the first is A/B layer polyethylene, which blocks moisture and bacteria; the second is paper board, which maintains the strength and toughness of the packaging sheet; the third is C/D layer polyethylene, which adheres to all layers; the fourth is aluminum foil, which blocks oxygen, odor and light; the E/F layer is polyethylene, which adheres to all layers; the G layer is polyethylene, which seals beverages and food.

We offer a best class tandem type extrusion laminating solution to meet the need of aseptic packaging industry today and a value-added investments for tomorrow.
