Manufacturing of tapes by PP Woven sacks :
The granules of Polypropylene woven bag sale are fed to
the extruder hopper, in which they are plasticized and
the melt drift is handed thru a T-die. Movie thus
produced is slit into the shape of tapes. These strips are
then orientated via stretching them under heated
condition at a predetermined ratio. Sooner or later the
tapes are wound on cheese winders. It's also feasible to
provide movies by using blown movie method, rather
than T-die extrusion. The compounding ingredients
used together with polypropylene and HDPE are
normally CaCO3 and master batch.
Weaving of tapes into fabric:
The tapes so acquired are fed to circular
looms/ flat looms and woven into tubular
or flat material respectively.
Lamination or extrusion coating
Cutting and sewing of polypropylene
