Film Extrusion

Plastic film extrusion is one of the most important processes in our industry. It accounts for around a quarter of all thermoplastics consumed and the film extruded is almost entirely for consumption in packaging – particularly food packaging - with the remainder going into agricultural and construction applications.

In its simplest form, the process involves pushing molten polymer through a circular or slot die. This continuous process enables the production of a consistent high quality product to extremely accurate gauge. For most thin gauge films, the film extrusion process takes the form of blown or cast extrusion.
