This blog will delve into the world of blown film manufacturing, exploring how Polytarp Products’ focus on quality, sustainability and customer satisfaction will enhance your business processes.
Blown film extrusion is a versatile and widely used manufacturing process in the plastics industry. Blown film manufacturing involves melting and shaping plastic resins (or polymers) into thin films, which can then be used in various applications, from food processing packaging to vapor barrier films and industrial applications like VCI (Volatile Corrosion Inhibitor) bags.
The process begins with feeding raw plastic resin (Polytarp exclusively extrudes Polyethylene) into an extruder. The extruder heats and melts the plastic, which is then forced through a circular die to form a continuous tube of heated plastic.
This heated plastic is then pushed through with air, forming a bubble. Think of it like blowing a bubble using bubble gum. The bubble is meticulously controlled through our carefully planned process that we have developed over the last 50+ years into a thin film. The film is then manipulated and customized to meet our customers’ requirements. If the application, for example is a combo, box or bin liner for a food packaging application we could customize it in a number of ways
At Polytarp Products, quality is at the heart of everything we do. Our blown film manufacturing process is no exception. We utilize our 13 state-of-the-art extrusion lines and our cutting-edge manufacturing technology processes to ensure that our films meet the highest standards of durability, consistency and performance.
