Following a successful exhibition at FullPlast (Chile), POLYSTAR has reached a new milestone with its 15th installation of its new generation recycling machine in the Chilean market, in only 22 months.
With strong after-sale and technical support by its local Chilean representative, POLYSTAR has established itself as a premium brand of recycling line that offers reliable and high performing equipment in the market with proven success and satisfied customers.
Efficient in-house recycling
In the example of Temuplas, plastic manufacturer of high and low-density polyethylene bags, with operations in Temuco city, Chile, has acquired POLYSTAR’s plastic recycling machine for recovering its in house production waste as well as waste collected from outside. The increase in price of raw material forces the plastic producer to cut down the use of virgin materials in order to reduce costs.
"We decided to bring our own recycling plant to process our own film waste and at the same time, creating surplus production capacity that allows us to collect industrial waste from other producers," said Mr. Ortiz, general manager of the Chilean company. The investment pays off rapidly because we are using less primary raw materials and savings in disposal cost.
Recycling has allowed Temuplas to save about 30 percent in raw material buying. The reuse of valuable secondary raw material has become indispensable for plastic producers today to stay competitive.
Recycling without quality loss: recycled pellets are ideal for reuse in blown film extrusion
With POLYSTAR’s recycling technology, the recycled pellets are put back into the blown film production process. The soft recycling process results in minimal material degradation without notable property change.
Examples of the waste are PE edge trim and roll (from blown film), HDPE and LDPE film scraps, left over waste from punches, both printed and non-printed film from the production waste are processed.
Some of the film products such as garbage bags are made of 100% recycled pellets, and the quality of the end product remains superb.
A high performing, user-friendly, one-step recycling technology
“With POLYSTAR’s recycling machine, we are currently processing 300kg per hour at a very stable and consistent rate,” says Marcelo Zurita, production manager of Temuplas. Besides being productive, the machine design is extremely user friendly and easy to operate. “Polystar has made recycling much more simple for us.”
The one-step technology (cutting + extrusion + pelletizing) requires minimal space labor intervention with consistently high and stable output.
The waste material enters the plastic recycling machine from the belt conveyor (for film scraps and rigid plastic regrind) and nip roll feeder (for film-on-rolls) at the same time. The feeding is controlled automatically based on how full the cutter compactor is. The cutter compactor then cuts, dries and compacts the material into a semi-molten condition (a gentle heating just below the agglomeration point), which is optimal for the extrusion process that follows. The cutter compactor then feeds the compacted material directly and consistently into the extruder screw.
