5 Layer Blown Film Lines

Pentafoil – 5 layer blown film line with CSD- Cylindrical Spiral Die (bottom fed vertical cylindrical spiral system) is state-of-the-art and provides optimized layout for rheological and thermodynamic criteria. Number of overlaps are almost unlimited, thus imparts excellent thickness distribution with broad range of operating parameters. Melt streams are designed and merged according to specific flow behaviour of polymers. It is compact in design with low axial forces. Sizes of all flow channels, all spiral dimensions and coex flow region are determined with the aid of computerized design and 3D simulation software. The die is self-cleaning. It is highly polished eliminating dead spots. Surfaces in contact with the melt are especially hard chrome plated and polished to ensure rapid flushing resulting in low wastage and short non-productive times during resin change.
