Tandem Extrusion Lamination Process

An outer clear film usually oriented polyolefin is printed preferably reverse printed with graphics.

Tandem extrusion lamination process.

In a tandem extrusion lamination with registered cold seal process a molten polyolefin extrudate is applied to bond the outer printed film to an inner film. This consists of a large roll a pressure roll and a counter pressure roll cooled by water. Tandem extrusion system 2020 03 30t07 20 49 00 00 for some polymers the pelletizing has to be done under the condition without water and moisture so that the extrusion system should have sufficient cooling capacity to cater for this process. Inside an extrusion coating and laminating line the substrates and melt are nipped at a bonding station.

It is a production line which outputs multi layered packaging material 3 4 5 layers with high speed in one process. Sml s lines can be used to manufacture complex composite carton packaging in one simple and cost effective process. Extrusion lamination is a similar process to extrusion coating where the resin is extruded between two substrates and acts as a bonding agent. Our high speed extrusion coating and laminating lines set the standard in industries maintaining flexibility for frequent product changes.

An ultra modern extension of extrusion coating and lamination is tandem extrusion lamination. Optional tandem or triplex line design.
