Single screw extruder and twin screw extruder work together to provide effective modification for film recycling applications, including BOPP film and PE films.

Single screw extruders with cutter compactor can recycle PP and PE films in one machine. After materials are melted, degassed, and filtered, they proceed to the second stage twin screw extruder for further extrusion and modification. This system allows for the addition of various additives including filling additives (CaCO₃, TiO₂), reinforcement modifications (short or long glass fiber), and masterbatch for color or degradation purposes.

Introducing the latest innovation from PR-Pulier, a company with over 18 years of expertise in the plastic granulation industry: the parallel co-rotating twin-screw extruder compounder. This state-of-the-art equipment is designed to meet the diverse needs of modern materials processing, delivering unparalleled performance and versatility.

Parallel co-rotating twin-screw extruders provide excellent mixing performance, ensuring materials are processed evenly for the highest quality output. Superior self-cleaning capabilities minimize downtime and maintenance for continuous, efficient operation. The machine's flexible, modular configuration allows easy adaptation to handle various materials and applications, making it an indispensable tool for any production line.

Whether involved in filling modification, reinforcement modification, masterbatch preparation, blend modification, or PET flake recycling, this extruder meets diverse processing needs. The twin-screw co-rotating mechanism ensures optimal material flow and mixing, delivering consistent and reliable results ideal for industries seeking increased production capacity and superior product quality.

Twin-screw extruders are the most common machines in the modified plastics industry, widely used in polymer processing and other production fields. They are categorized into meshing and non-meshing types, with meshing types further divided into co-rotating and counter-rotating configurations.
