Compact design with small floor space, easy operation and accurate, reproducible positionings as well as quick changes of products and parameters are what makes COLLIN blown film lines so unique.

They are used for function tests of polymers and compounds, for the development of multi-layer films, the quality con-trol of the pigment dispersion, the control of the dispersing behaviour of compounds and extruders or for the production of small film hoses in the food or medical sector.

Blown film lines with air cooling of the film

Blown film lines with a diameter of 20 to 120 mm are suitable for the production of hoses with lay-flat widths of up to 790 mm.

Blown film lines with water cooling of the film

These COLLIN lines are used for the production of infusion bags or other mono or multi-layer products. Vertical extrusion into a water cooling ring delivers optimal film transparency, e.g. suitable for PVC-free infusion bags or blood plasma bags.
