The Recycling Challenge

Plastic film production and printing generate substantial waste: defective rolls, misprinted material, and end-of-run remnants. These rolls share common traits: high-quality plastic, large diameter (up to 1,600 mm), long length, and an internal paper core that cannot be removed by hand.

Standard plastic crushers cannot handle rolls this large. Manual cutting is slow, labor-intensive, and expensive. But the bigger problem is the paper core. If shredded together, paper fragments mix with plastic and cannot be separated by hand. This contamination blocks screen changers on downstream pelletizing lines, causing production delays and maintenance headaches.

A standard single shaft shredder is not the answer. The paper core must be removed before shredding.

The Wanrooe Two-Step Solution

Core Separation

A hydraulic cutting machine with 160-ton cutting force slices the roll in half. The worker easily pulls out the exposed paper core. No manual wrestling, no partial removal. Clean separation in seconds.

High-Capacity Shredding

The de-cored film roll feeds directly into a swing-type vertical drum shredder. Cavity size up to 2,500 mm accepts the full roll without pre-cutting. Throughput reaches 3,000 kg per hour. The film shreds cleanly without dispersing or wrapping, producing uniform fragments ready for agglomeration and pelletizing.

The specific production process is:

FAQ: Film Roll Recycling

Can I shred the roll without removing the core?

Technically possible but strongly discouraged. Mixed paper-plastic output contaminates the pelletizing process, blocks screens, and degrades pellet quality. The two-minute core removal step saves hours of downstream trouble.

What roll sizes can the system handle?

The hydraulic cutter handles rolls up to 1,600 mm diameter. The swing shredder cavity accepts up to 2,500 mm. For larger rolls, custom engineering is available.

Does the system work for printed and laminated film?

Yes. The swing shredder is designed for printed, laminated, and multi-layer films. Ink and adhesive residues do not affect shredding performance. Downstream washing may be added if pelletizing requires higher purity.
