Products Details
The SL-450 Three-Servo Air-Exhaust Flow Wrapping Machine is a horizontal flow wrapper for bulky or compressible products that need excess air pressed from the bag before final sealing. The demonstrated application packs steel-wool scrubbers. This is a mechanical air-exhaust or compression flow-pack system, not a vacuum-chamber packaging machine.

The source specification does not state packaging speed or residual-air level. Final performance depends on product compressibility, pack dimensions, air-exhaust mechanism and film sealing behavior.
Key Functions
- Three-servo independent motion control
- Product detection and automatic infeed positioning
- Empty-pack prevention and anti-cut control
- Mechanical air removal or product compression before sealing
- Photoelectric registration for printed film
Typical Applications
- Steel-wool scrubbers and cleaning pads
- Sponges and other compressible cleaning products
- Folded towels and selected textile or hygiene items
- Other bulky products requiring reduced bag volume
Process Boundary
This machine mechanically presses excess air from a compatible compressible product, forms a pillow-style flow pack and completes the longitudinal and end seals. It does not create a controlled vacuum, gas-flush atmosphere or verified residual-oxygen level, and it is not a substitute for chamber vacuum packaging. It also does not manufacture or inspect the packed product.
Automatic loading, compression tooling, leak testing, checkweighing, labeling, cartoning and case packing require separate confirmed equipment or options.
Information Required for a Quotation
