Blown Film Polyrema owns a large assortment of second hand machines. It is therefore not possible to list all parts. Should you request something special (machine parts or electrical parts) that are not listed, do not hesitate to call us. We can also provide for example with certified Reta Thyristor controler; Latron single and compact controller, which may be mounted in your lines but are no more available on the market.
Extruders from 30 mm diameter up to 150 mm of “normal” design with 30D screw length, or special designs, for example for the extrusion of water soluble film.
No matter which bubble diameter and which raw materal are concerned: Polyrema can offer the suitable sizing cage – from manually adjustable designs with silicone-coated rolls to motor-adjusted sizing cages with extra-long stroke, carbon fibre rolls and monomer exhaust.
We offer stationary and reversing haul-off units, film centering guides, and film pretreatment units. You can purchase these and many other components directly from Polyrema. Our collapsing frames are available with aluminum and carbon fiber rollers as well as with wood slats and cooled rails. Our standard setups include gusset boards and A-frames, both of which we can readily adapt to your individual requirements. The same applies to all other downstream equipment.
Flat-bed winders with contact winding for film widths from 300 mm to 3400 mm, available as single-station winder and tandem winder "back-to-back". Especially for HDPE, we offer a version with very high haul-off speeds. This allows to realize high outputs with optimum quality of films of about 5 µm thickness.
We offer complete new blown film dies and new die inserts. This refers both to mono and multi-layer dies for different materials, such as PE, EVOH, PP, PA and PU. Some designs are also available as reversing blown film die.
