Small Bag Packer
CYprocess small bag packing machines — also called open-mouth baggers or weigh-fill bagging lines — fill 5-50 kg open-mouth bags under electronic weighing control, then pass them to an automatic sewing or sealing station on a guided outfeed conveyor.

Overview
About Small Bag Packer
How this equipment works in powder handling lines and what to consider when selecting it.
Working principle
The bag is placed on the filling spout and held by a roller support while product is fed in. Fast and slow feeding stages bring the weight to the setpoint, the bag is released onto the outfeed conveyor, and the sewing or sealing head closes it. The operator's task is limited to presenting bags.
Options and integration
Screw, gravity and impeller feeding cover different material behaviours, and the touchscreen weigh controller stores recipes and target weights. Options include dust extraction at the spout, de-ironing, heat sealing and a valve-bag filling head for a different bag type.

Model range
| Item | CY-SB-25H | CY-SB-25S |
|---|---|---|
| Packing weight (kg) | 20 - 50 | 20 - 50 |
| Speed (bags/h) | 30 - 50 | 40 - 60 |

FAQ
Small Bag Packer FAQ
Common questions about selection, integration and quotation.
Typically 5-50 kg open-mouth bags, with 25 kg the most common retail and industrial size. Bag length and width are matched by adjusting the spout and the conveyor guides, so changing size is a mechanical set-up rather than a rebuild.
