PVB film Shredder Machine
What is PVB and PVB film?
Polyvinyl butyral (PVB) is a resin which actually is a clear, colorless and amorphous thermoplastic. It is from the condensation reaction of polyvinyl alcohol and butyraldehyde. Since it has excellent flexibility, UV resistance, film-forming and good adhesion properties, it is mostly available for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. PVB can be cross-linked. And PVB film is produced from the chemical modifications from the condensation reactions of OH groups in the polymer, phenolic, epoxy, melamine resins and isocyanates.
PVB film application
Laminated safety glass for automobile windshields and construction industry is the main application of PVB film. Also photovoltaic industry uses it to improve the long-term durability of solar modules.
How to recycle PVB film?
Take PVB films for automotive purpose for example. When vehicle is at the end of service life, you can recover the windshield from a waste vehicle and collect them together since PVB film is inserted in the case of windshield. Then you can screen the windshield and separate PVB film from glass. Of course, you should remove the attached glass and fine glass from the separated PVB film further. The size reduction of PVB film is quite important in whole PVB film recycling. A standard PVB film recycling system contains a PVB film shredder and a PVB film granulator for further size reduction to ideal particles. Finally PVB film will be extruded for new recycled material purpose.

Recycling PET film is a multi-step process that transforms used or waste PET film into reusable raw materials like PET flakes or pellets. While PET bottles are widely recycled, PET films (such as packaging films, protective films, and industrial laminates) require more careful handling due to their thin, flexible, and sometimes multilayered nature. A PET film shredder is a machine designed to reduce polyethylene terephthalate (PET) film into smaller, manageable pieces or flakes for easier handling, recycling, or further processing (e.g., granulating or washing).
