Kuhne Anlagenbau designs and manufactures blown film dies optimized for every application. For top quality and reliable supply, the dies are manufactured in-house in a state-of-the-art facility that guarantees the tightest design tolerances.
Triple Bubble® sausage casings
Artificial sausage casings are typically produced in 3-, 5- or 7-layer lines, where we have the option to use the well proven ReCon (regular concept) spiral mandrel design. An alternative to consider is our MoCon® (modular concept) stackable plate die, which allows much more flexibility in structure design. Both options, in conjunction with our precise manufacturing technology, delivers tight thickness tolerances for very thin layers.
Triple Bubble® shrink films
Systems with 9, 11 or 13 layers are now the industry standard for bioriented shrink films. For mid-size lines, up to 9 layers, we developed our HyCon® (hybrid concept) die consisting of a core of spiral mandrels with the outer layers applied via stackable plates positioned just before the die exit. These layers can be heated independently of the temperatures of the rest of the die, a very important feature for PA or PET outer layers.
For systems with 11 or 13 layers (17 layers are possible) it is crucial to ensure the best thickness uniformity for the very thin layers at the center of the film structures. In this case our MoCon® (modular concept) stackable plate die offers the best solution. It also allows the most versatile use of the entire extrusion line since in these cases the MoCon® die would typically be fed by equal size extruders. Besides delivering the best combination of high output and excellent thickness control, our MoCon® die can operate with pressures up to 1000 bar if required.
Additionally, our MoCon® die can be configured to process heat sensitive resins like PVDC without degradation. This is done with thermal isolation by using additional insulating plates on either side of the PVDC layer. If necessary, this same layer can also be used to process EVOH without any changes.
Triple Bubble® non-shrink films
The die concept specified is contingent of the application and the polymers used. Typically, systems with 7 and 9 layers are equipped with our HyCon® (hybrid concept) dies, especially in cases where high melt temperature polymers need to be processed, as with heat resistant outer layers for example.The most versatile concept, often used for polyolefin rich structures, is the MoCon® (modular concept) stackable plate die. It is ideal for film structures with up to 13 layers (17 layers are possible) since this design will provide a shorter flow path and an optimal residence time. This concept offers maximum flexibility so that new market requirements, such as films designed for recyclability, can be fulfilled quickly and without additional costs.
