Printed BOPP Film Recycling
BOPP (Biaxially Oriented Polypropylene) film with printing is used in flexible packaging, labels, floral wraps, posters/banners, and many others to display designs and product information using ink.
The recycling process of printed BOPP films requires pelletizing machines with specialized degassing systems depending on the percentage of printed surface on the film in order to ensure quality pellets.

High Performance Recycling Machine for BOPP Film with Print
POLYSTAR's high efficiency, one-step plastic recycling machine BOPP Flex is designed specifically for the reprocessing of BOPP post-industrial film waste, printed, non-printed and heavily-printed.
The newly-designed cutter compactor has been specially modified and strengthened for BOPP film which is more difficult to cut and compact comparing to PE film, due to its high tensile strength through the stretching in both the direction of the cast machine.
High quality pellets made of BOPP recycled materials allows producers to use them back into their production lines for applications such as injection molding or others.
Degassing
High performance degassing is one of the most important elements in BOPP film recycling to ensure that the pellets are not fluffy or contain holes in the middle. Polystar’s double-vented degassing and the re-positioning of the filtration system to the front of the degassing system on the BOPP Flex make sure that degassing is done ideally and optimally on printed BOPP film. This guarantees high quality pellets which are solid in the middle and uniform in size.
Easy pelletizing
Polystar’s specially designed die-face pelletizing system prevents water from splashing back onto the die head and blocking the holes on the die surface (which typically prevents material from coming out of the die head and creates problems in the pelletizing process). Most die-face cutting pelletizing systems on the market today face problems when processing BOPP film and PP material in general, particularly with pellets sticking together or producing un-uniformed sized pellets. POLYSTAR’s re-engineered die-face pelletizing system can pelletize BOPP, CPP and OPP as easily as processing HDPE and LDPE film waste.
