High-Efficiency BOPP Film Recycling & Pelletizing Machine

Biaxially Oriented Polypropylene (BOPP) is widely used in flexible packaging, film manufacturing, and labeling due to its high transparency, moisture resistance, and mechanical strength. However, recycling BOPP presents distinct technical challenges:

Low Bulk Density: Loose BOPP film is extremely light and fluffy, making it difficult to feed into standard extruders.

Thermal Sensitivity: Excessive heat during processing degrades the polypropylene polymer chains, causing yellowing and reducing tensile strength.

MFI (Melt Flow Index) Shifts: Uncontrolled heating drastically alters the viscosity of the recycled resin, reducing its market value.

The Solution: Successful BOPP recycling requires pre-densification with controlled thermal input before extrusion, paired with high-vacuum degassing and precise melt filtration.

Compatible Raw Materials:

Our high-efficiency recycling line is versatile and optimized for a wide variety of BOPP scrap and film waste formats:

BOPP Film Rolls & Off-cuts: Edge trim waste from slitting lines, factory off-cuts, and reject rolls.
Printed & Unprinted BOPP Films: Food packaging film, candy wrappers, and cigarette packaging film.
BOPP Laminated Scrap: Multilayer films, BOPP/CPP, and BOPP/PE laminated scraps.
Post-Industrial BOPP Waste: Crushed bags, garment bags, tape backings, and woven bag scrap

Machine Working Workflow (Step-by-Step):

Our system uses an advanced Cutter-Compactor-Extruder integration to turn loose waste into high-quality pellets in a continuous, automated process:
Feeding System (Belt / Roll Feeder): Loose film scraps or continuous film rolls are steadily conveyed into the cutter-compactor using speed-controlled feeding.
Cutting & Pre-Compacting: High-speed rotating blades shred, friction-heat, and pre-densify the fluffy film into dense, semi-molten flakes without degrading the polymer.
Forced Extrusion: Densified material is directly forced from the compactor into the extruder barrel, ensuring continuous high-throughput feeding without clogging.
Low-Temperature Melting & Degassing: Precise multi-zone heating melts the material uniformly. High-vacuum degassing zones draw out trapped air, printing inks, and moisture.
Continuous Melt Filtration: A non-stop hydraulic screen changer removes microscopic contaminants before pelletizing.
Water-Ring Pelletizing & Centrifugal Drying: The clean melt is cut at the die face under water, cooled instantly, and centrifugally dried into uniform, high-transparency granules.

Key Product Features & Technical Advantages:

Integrated Cutter-Compactor:
Pre-densifies fluffy BOPP film on the fly, eliminating the need for a separate pre-crusher.
Thermal Protection Screw Design:
Specially engineered screw geometry preserves the original MFI and optical clarity of the BOPP resin.
Dual-Zone Vacuum Degassing:
Ensures bubble-free, high-density granules even when processing printed films.
Non-Stop Hydraulic Screen Changer:
Allows filter screen changes without stopping production, ensuring continuous 24/7 operation.
Smart PLC Controls & Variable Frequency Drive:
Maximizes energy efficiency, reducing total power consumption by 20–30%.
