One of the mainstay methods of film manufacture is Blown Film (or Tubular Film) Extrusion. Blown Film Extrusion facilitates high-speed production of both tubular and gusseted film with precise control. Both the output of the extruder and the speed of the haul-off can be closely managed. The level of control available in Blown Film Extrusion is outstanding. Specifically, we are able to regulate the thickness and width of the film by manipulating the volume of air in the resin.
Other benefits include even spread of temperature, uniformity of mechanical properties, and the complete elimination of edge bead trim and other undesirable end effects.
These characteristics provide clear benefits, enabling us to turnaround large volumes of custom film at short notice, with particular emphasis on co-extruded, multi-layer films such as those used by the food and drink industry as food-grade packaging.
One of Marpak’s mainstay processes is mono layer blown film extrusion. Blown film extrusion facilitates high-speed production of both tubular and gusseted film with precise control using our state of the art gauge control, as well as including uniformity of mechanical properties. This results in products that provide reliable performance. We tailor our processes to suit our customers’ requirements.
