DR-Pack: New cooling unit to enhance stretched film production

The Hungarian plastic processing equipment manufacturer DR-Pack that is notably a specialist of blown film machinery has developed and patented an innovative intensive air-cooling system specially designed to enhance the quality and the production speed of stretched films. The DR-Pack system is based on the reduction of the amount of cooling air by closing the conical section of the bubble that is not involved in air flow. The new cooling unit can be combined with an especially planetary gear with integrated bearings, an infrared heating ceramic heaters for extruder and a die with a rotating core. That allows to offer material saving thanks to a better monitoring of film thickness.
