WANROOETECH’s CPP BOPP film recycling pelletizing machine is a complete double-stage recycling system designed for CPP and BOPP film—one of the most common packaging film materials. This solution efficiently handles abandoned printing film containing inks and impurities that ordinary single-stage pelletizing machines cannot process. The integrated line includes shredding, compacting, plasticization, and pelletizing with PLC intelligent control requiring only 2-3 operators. With 25 years of recycling experience, WANROOETECH has optimized machine designs specifically for CPP/BOPP film characteristics, delivering high output with low energy consumption.

CPP BOPP Film Recycling Pelletizing Machine Process flow:

CPP/BOPP film→belt conveyor→metal detector→film compactor→mother extruder →hydraulic screen changer →baby extruder→hydraulic screen changer →pelletizing system →air dryer blowing system→ storage hopper→ finished product packing

Detailed description of each item:

1. Conveyor: convey PP PE film or flakes into the compactor.
2. PE film Agglomerator /Compactor: crushing and compress film, and feed compressed film into extruder forced, to make the production capacity high and stable.
3. 1# Extruding system: plasticizing material and exhausting gas.
4. 1# High speed Net exchanging system: filter material impurity, to make production more stable.
5. 2# Extruding system: plasticizing material.
6. 2# High speed Net exchanging system and Die-head: Second filter material impurity, to make production more stable.
7. water ring pelletizing machine: cutting pellets in water.
8. Water tank: cooling pellets.
9. Dewater machine: make pellets dry.
10. Vibration sieve: remove bad pellet and keep good pellet.
11. Air Blower: convey good pellets into the silo.
12: Storage silo: keep pellet.

CPP BOPP Film Recycling Pelletizing Machine Features:

Modular Screw Design Screw components allow free assembly based on raw material type. Different CPP/BOPP film formulations, contamination levels, and ink contents can be accommodated by selecting appropriate screw geometries without complete screw replacement.
Flexible Cutting Options Suitable die heads support multiple pelletizing styles: water ring cutting for standard applications, under-water cutting for high-output operations, and hot face cutting for heat-sensitive materials.
High-Efficiency Force Feeding The compactor’s force feeder ensures stable high-capacity material feeding into the extruder while maintaining low power consumption. This prevents bridging and feed inconsistency common with light, bulky film materials.
Vacuum Exhaustion System The main screw features vacuum exhaustion that removes moisture, volatile ink solvents, and decomposition gases during plasticization. This prevents bubble formation in pellets and ensures high-quality output.
Integrated Drying System The water ring granulator includes an attached dryer that rapidly removes surface moisture from pellets, reducing the need for separate thermal drying equipment and saving energy.
Specially Designed Single Screw Extruder Custom-engineered screw, barrel, and venting system configurations ensure optimal plasticization of CPP/BOPP film. The design accounts for the specific melting characteristics and thermal sensitivity of oriented polypropylene films.
Precision Pellet Cutting Standard cutting with extrusion mould ensures even cutting and consistent pellet shape. Uniform pellet dimensions improve bulk density, flow characteristics, and downstream processing performance.
