Extrusion Coating Laminating Machine WEL
Product Description +

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.

Co-extrusion


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.
