DUAL SPIRAL SYSTGM

nnnn

In the packaging or blow film market, where suppliers are struggling to keep up

nnnn

with ever changing industry requirements, the constant objective is to improve

nnnn

co-extruded film or blow molded products performance. To do this, the successful

nnnn

packaging supplier must have the most versatile equipment that can accommodate

nnnn

a vast array of potential structures at low production costs.

nnnn

The Alpha Dual Spiral System (which allows material to flow through the top and

nnnn

bottom layer in an "Over-Lay" mode)(Patent Pending) represents an important and

nnnn

significant advancement in the technology of blown film machinery. Alpha has

nnnn

proven itself as being able to offer its customers advanced equipment like this. The

nnnn

ADSS effectively doubles the number of layers in a film die by distributing the melt

nnnn

on two separate identical distribution spirals and recombining the resulting layers

nnnn

together before exiting the die. This produces films that are stronger, with improved

nnnn

barrier properties while at the same time increasing the output and lowering the

nnnn

system pressure of the die. The ADSS is the only die on the market that can offer this

nnnn

feature. The ADSS die is already being used commercially by a number of film

nnnn

manufacturers with great success.
