blown film extrusions
As a technology partner for polymer producers, developers, universities, and processors — Rajoo has consistently followed impelling technological developments in plastics extrusion with its own new developments.
Rajoo has supplied 5 lab lines of various configurations to the world’s polymer giants like Reliance Industries & IOCL.
LabEX — Combo can be used as a laboratory line for testing and developing of new formulations and products, process and parameter control is of utmost significance. An innovative barrier sheet cum blown film line is one of its kind in the whole world.
This combo line consists of four extruders, screen changers, melt pumps, flat sheet die, Universal Co ex Five Layer blown film die head UCD®, and a fully automatic touchscreen-based integrated process control panel to give an output of up to 75 kg/hr. of co-extruded barrier sheets or films.
The machine operates either as a sheet line or as a blown film line. Extruders are common to both the set-ups. A novel system easily converts the line from blown film extrusion to sheet extrusion setup and vice versa. The line is designed to produce HIPS, EVOH, and PP sheets of up to 650mm width in a thickness range from 0.2 mm to 0.8 mm and barrier-blown films of PE, PA, and EVOH from 25 to 100 microns.
Rajoo has also developed the world’s smallest 3-layer blown film line(LabEX — Nano) to give an in-depth understanding of how various resins, their % and process conditions affect high output blown film production and properties using a small amount of resin and less power consumption which finally leads to very low operational cost.
