Process Of Extrusion Lamination

Extrusion laminating is a similar process except that the extruded hot molten resin acts as the bonding medium to a second web of material.

Process of extrusion lamination. Extrusion lamination is a similar process to extrusion coating where the resin is extruded between two substrates and acts as a bonding agent. In addition by laminating pe onto oriented nylon films ony barrier films or other similar films various types of plastic products such as food packaging films can be obtained. Extrusion lamination is a converting process that allows two different materials to be combined in line to achieve a multi layer sheet structure. Extrusion lamination brings two films together using a layer of molten resin extruded through computer controlled extruder dies with advanced gauge controls nuclear gauge monitoring and automatic profile control.

Inside an extrusion coating and laminating line the substrates and melt are nipped at a bonding station. Extrusion lamination process water resistant paper products such as milk cartons can be obtained. Either a continuous glass mat made in a random configuration or a chopped glass strand mat made with 0 5 in. During the extrusion lamination process the selected polymer is extruded through the die in the form of a sheet and acts as the substrate for the film to be laminated onto.

As an example azdel a glass reinforced thermoplastic composite made with continuous glass mat is produced using an extrusion lamination operation. The extrusion lamination process can be repeated until the final flexible packaging structure is complete or it can be combined with adhesive lamination to create the final. 12 7 mm or longer glass fibers is added between layers of resin.
