The advantages of Repro-Flex and grow up with the honorable customers for bright

1. An Integrated system without the need for pre-
crushing:

The integration of the cutter compactor directly with
the extruder eliminates the need for pre-crushing
plastic ?lm. The feeding is therefore much faster and
more stable. High throughput with the light-weighted
?lm ?akes can be easily achieved by going through
densi?cation and compacting process ?rst.

2. High automation with flexible waste feeding
methods:

The Repro-Flex recycling system can process scrap
material on a conveyor and ?lm-on-roll on nip roll
?lm feeder simultaneously. This automates the entire
process and is bene?cial for producers in terms of
labor cost saving, space saving and lowering energy
consumption. The machine generates very low noise
as it does not require a separate crusher to process
the ?lm waste in advance.

3. Lower operation cost (less space, lower energy
consumption and lower labor cost):

Polystar's plastic recycling systems can process heavily
printed PE/PP ?lm in just one single extrusion stage.
This replaces the traditional "two stage" mother-baby
