Packaging production spans rigid formats like thermoformed clamshells and blow moulded bottles, flexible film and pouches, corrugated and carton board, and foil or laminate materials, each generating its own mix of matrix, trim, and scrap. Manually managing these different waste streams across converting, printing, and packaging lines slows changeovers and increases floor space and manual labour requirements.
Every trim, punch-out, and off-cut your line produces is either moving toward recovery or piling up next to a machine. Pneumatic systems capture waste the moment it’s created, right at the slitter, die-cutter, or rewinder, so high-speed packaging lines keep running instead of stopping for cleanup.
Systems are built from standard modular components such as blowers, separators, cutters, or all-in-one units, and sized to your line and waste streams.
Featured Case Study
Manual scrap removal can’t keep pace with a flexible film line running at up to 400 m/min. A Polish flexible packaging producer now extracts and shreds trim automatically with MultiCutters and KU static separators, conveying it 95 m horizontally and 12 m vertically to collection.

Film, foil, laminates, and metalized laminates can all be conveyed and separated pneumatically. Each system is configured for the material it handles, with gentle handling and dedusting and separation that keep material suitable for in-house recycling.
Rigid packaging, such as thermoformed clamshells or blow moulded bottles, produces matrix and skeleton waste that is typically granulated and evacuated after forming. Flexible packaging, such as film and pouches, produces continuous trim and off-cuts that are conveyed directly from the line. Each packaging waste handling system is configured for the material type.
Yes. Pneumatic systems remove trim, punch-outs, and downsized skeleton waste from carton and cardboard production. They can also convey shredded scrap to a central collection point, baler, or compactor.
Yes. An Inline Venturi system can be used to convey low specific weight materials, such as EPS and EPP beads, to and from silos or trucks while maintaining bead density and integrity, reducing material cost in expanded bead packaging production.
Performance depends on the packaging equipment, material, trim size and waste volume. Continuous film or foil edge trim can be handled at line speeds up to 1,000 m/min, with higher speeds possible under certain operating conditions.
Packaging waste can be conveyed up to 150 metres from slitters, winders and converting equipment. Longer distances may be possible depending on the material, waste volume, pipe route and operating conditions.
Pneumatic systems remove trim, punch-outs, and rejects from the line continuously, so operators don’t have to stop production to clear waste by hand. Trim is extracted at the slitter or rewinder and conveyed through enclosed pipes to a central collection point, keeping the area around each machine clear.
Waste is collected where it is produced and conveyed through pipes to a collection or recycling point. Cutters or shredders downsize continuous matrix or larger skeletons where needed, while separators remove the waste from the conveying air.
Yes. A central system can collect waste from several converting or printing machines. Capacity and airflow are matched to the waste volumes and the machines operating together.
Packaging producers can reduce energy use by sizing the system to actual waste volumes and using variable-speed blowers that provide only the suction needed for waste evacuation. Requirements depend on the packaging material, waste dimensions, conveying route and capacity. Where suitable, pressure conveying with an injector can also be used, with no moving parts in contact with the material. Kongskilde engineers select the conveying method, blower and components for each production line.
Yes. Systems can use separate conveying routes or collection points to keep material streams apart. This supports recycling, but does not separate the bonded layers of laminates or make all packaging waste recyclable.
