Configuring VFFS Jaws for Clean Confectionery Cross-Seals
Retail peg-board pillow bags and block-bottom gusseted bags account for the highest unit volume in VFFS candy bagging machines. Across our candy packaging machines builds, jaw kinematics and product-drop synchronization separate clean 90 BPM runs from crushed-candy seal leaks.
Intermittent servo cross-jaws excel at 10–70 bags/min across broad bag sizes (60–250 mm width, 100–350 mm length), while rotary/box-motion continuous frames push pillow packs to 90–120 BPM.
Pillow vs Side-Gusset vs Quad-Seal VFFS Comparison
Choose the forming and jaw package based on retail display style:
| Bag Format | Shelf Presentation | Typical Speed (520 Frame) | Required Jaw / Former Add-On |
|---|---|---|---|
| Standard Pillow Bag | Flat lay-down or peg-hook display | 15–120 bags/min | Standard round/oval collar + serrated knife |
| Euro-Slot Hang Bag | Convenience & checkout peg racks | 15–85 bags/min | Pneumatic/heated euro-hole jaw punch |
| Side-Gusseted Bag | Compact brick profile in display cases | 15–65 bags/min | Synchronized pneumatic side-tucking fingers |
| Quad-Seal Stand-Up | Crisp 4-edge vertical shelf block | 20–50 bags/min | 4-edge vertical seal bars + rectangular tube |

Confectionery Engineering Details
- Jaw Obstruction Detection: Servo torque monitoring re-opens cross-jaws instantly if a hard candy lags in the seal zone, protecting knives and preventing wasted film.
- Chain-Bag Strip Option: Program perforated multi-bag strips (e.g., 6 or 12 connected small candy sachets) for hanging retail strips.
- Cooling Air at Cross-Seal: Compressed air chill jets solidify thick laminate gusset folds before heavy candy charges hit the bottom seam.
Match Film Structure to Seal Speed
High-speed 90–120 BPM runs benefit from low-initiation-temperature metallocene LLDPE or CPP inner sealant layers.
