POLYSTAR - How to Reprocess Highly Printed Films? PE, PP, BOPP

The industry of plastic has been changing and
evolving over the years that’s why plastic recycling
has become a necessity among plastic producers.

The laws toward plastic have become stricter, which require
the producers to use a higher percentage of recycled material in their
final products. The benefits of these laws are for lowering the production
cost of the producers and reducing the plastic waste in our environment.

New standards for plastic pellets

Plastic producers and professional recyclers started
to pay more attention to products that can be
recycled but were difficult to reprocess.

Here are the examples:

Highly printed film (PE and PP)
Flexible packaging
Laminated film
Multilayer film
BOPP film

It is common that recycled pellets from these materials don’t possess the best quality.
Producers can notice this when pellets are used again in the production line (blown film
machines and injection machines). In other words, getting better quality pellets has
become the priority for plastic producers.

Why should you reconsider a
two-stage recycling machine?

Polystar, through reengineering, designed the perfect solution: Repro-Flex Plus.

Repro-Flex Plus is able to reprocess the highly printed material and improve the quality and the productivity of the recycled pellets. With a two-stage recycling system, two filtration and three degassing steps ensure the minimal degradation of the material, which produces uniform pellets for reprocessing directly into your production line.

Simple in design. Simple in operation.

Cutter compactor- This cutter integrated pelletizing system eliminates the necessity of
pre-cutting the material, because the cutter-compactor pre-cuts, pre-warm and mix the material that will be feed directly into the extruder with a centrifugal force.

Two-stage recycling system- Special design on the first and second extruder.
The second extruder stabilizes the process, reducing the degradation of the material.

Tripe degassing- In addition to the double degassing in the first extruder, the venting area (the connection between the first and second extruder) serves as a third degassing section to further remove the ink and extra humidity level from the material.

Higher capacity and cost reduction.

Repro-Flex Plus is designed with advanced technology, which reduces the operational cost and energy consumption. Both plastics producers and recyclers have noticed the benefits of Repro-Flex Plus, while recycling laminated films, multilayer films and films with highly percentage of printing areas on the surface.

Finally, Polystar offers not only simple solutions for plastic producers, but also instant after-sales services. What’s more, Polystar has agents and technicians around the globe. These representatives specialized in Polystar Machines, giving machine installations and after-sales as well.
