Plastic bag making machine SFB - WPP, BBR - WPP

Overview
Reliable, precise and compact machine for the high-efficiency production of pinch-bottom side-gusset bags from poly-woven (PP) material. Designed for stable packaging units and maximum process safety.

Product description
The SFB-WPP forms pinch-bottom side-gusset bags from flat poly-woven PP fabric. Configurable pinch closure and bottom sealing (hot air or hot glue) deliver a stable bag shape suitable for display and transport. With appropriate configuration the machine handles up to 120 bags per minute with side gussets and pinch bottom.

Highlights

• Hot-air sealed pinch bottom
• Pinch bottom configurable to front or back panel
• Hot-air sealed longitudinal back seam for clean, strong seams
• Top slider option for easy opening
• Non-stop roll change (web change during operation)
• Inline quality inspection (camera and sensor systems) with automatic reject
• Options for automated packaging via robotics (LEAP)
• Rotary die cutter and flush-cut options
• Laser vent-hole perforation on request; rotary punch as low-maintenance alternative
