For Sale - PCM - 1438 - ALPHA DUAL SPIRAL CO-EXTRUSION

In the packaging or blow molding market, where suppliers are struggling to keep up with the ever changing industry requirements, the constant objective is to improve co-extruded film or blow molded products performance. To do this, the successful packaging supplier must have the most versatile equipment that can accommodate a vast array of potential structures at low production costs.


The Dual Spiral System (which allows material to flow through the top and bottom layer in an "Over-Lie" mode) (Patent Pending) represents an important and significant advancement in the technology of blown film machinery. The DSS effectively doubles the number of layers in a film die by distributing the melt on two separate identical distribution spirals and recombining the resulting layers together before exiting the die. This produces films that are stronger, with improved barrier properties while at the same time increasing the output and lowering the system pressure of the die. The DSS is the only die on the market that can offer this feature. The DSS die is already being used commercially by a number of film manufacturers with great success.


The DSS provides a doubling of the number of layers in a die, superior streamlining and mixing of melt-flow, temperature isolation and a new standard in die design for simplicity and flexibility to add layers to the die configuration. The DSS is available from 1 to 11 layers, in die sizes of 1-55 in (25-1400mm).
