Worldly's extrusion coating and laminating expertise is second to none. With the industry's most versatile equipment platforms, we deliver cost-effective packages at all levels of sophistication to support flexible packaging, non-wovens, paper and board coating and laminating applications.
In order to provide cost cut multi-layer lamination and advantage of mass production each machine is equipped with anchor coating unit, unwinder, sandwich unwinder and lamination unit.
Furthermore, customers are entitled to select a co-extrusion type of machine to produce multi-layer lamination by using one Tie-die.
In addition to one station operation , two stations and three stations operation are only on step away.

(2) Automatic Taper tensions can be easily adjusted on the touch panel according to the different material specifications for curve, slope, or straight three setting modes.
(3) Two additional touch rollers for both rewinding shafts are pneumatically pressure control ensure the smoothness of the rewinding material without any sliding.

Co-extrusion is a process of extruding a multi-layer structure with two or more type of resins without premixed through one die simultaneously, so that all the different resins come together as a single proportionally assigned integral structure.
Through a feedblock, each layer is carefully calculated; assigned and extruded through one single T-die.
The advantages of barrier coextrusion are to obtain a multilayer material in one operation and to use only a thin layer of expensive barrier material coextruded with cheaper supports and dry adhesives.
In most of cases, expensive adhesive will be used in bonding no-porous material with minimum volume to achieve sufficient bonding strength.
