Stretch Wrap Film

Manufacturing of Blown Film - All blown films, whether Mono (Single Layer) or Co-Extruded (two or more layers) have the granular resin and any additives fed by a heated screw barrel, forcing the molten resin into a circular die. The molten resin is then blown vertically upwards and outwards (commonly called a bubble). The Bubble is gradually cooled by air as it ascends the tower. At the top of the tower the film is nipped together and drawn down to the slitting and winding stations via guide rollers. Blown Film is the preferred manufacturing method to achieve higher Mechanical Properties. The manufacturing costs are higher because the bubble is cooled by air.PLEASE VISIT OUR WEBSITEw w w. avpack. synthasite. com
