Roll-fed form-fill-seal machine FL series

for food packagingautomaticPLC-controlled

Overview
This automatic VFFS packaging unit integrates a multihead weigher and vertical form-fill-seal system for precise weighing and efficient packaging of granule products such as pet food, chips, nuts, snacks, rice, seeds, sugar, spices and small hardware. Models cover small to large production and have been exported to markets including USA, Australia, Russia, Poland, Italy and Germany.

Applications

• Pet food: dry kibbles, treats (retail and bulk)
• Snack & confectionery: chips, nuts, candies, biscuits, puffed snacks
• Grain & agriculture: rice, seeds, beans, sugar, salt, spices
• Daily chemicals: washing powder, desiccant, cat litter, small hardware
• Food processing plants: integration for small to large automated packaging lines

How the collar-type weigher packing machine works

• Feeding roll film: Roll film is fed automatically into the forming system.
• Forming bag: A collar-type former shapes the film into a vertical bag ready for filling.
• Feeding and sealing: The multihead weigher doses product into the formed bag and the VFFS seals the bag.
• Discharge: Sealed bags are cut and transferred onto the finished product conveyor for collection.

Features

• High-precision multihead weighing to reduce waste and maintain consistent bag weights.
• Supports back-seal, gusseted, hanging-hole and stand-up pouch formats.
• Color touch HMI for parameter configuration, language selection and bag alignment.
• Servo-driven dual-belt film traction for stable bag forming and accurate lengths.
• Separate air and electrical cabinets to reduce noise and improve circuit stability.
• Enclosed, dust-proof structure protecting internal components.

Advantages

• High packaging throughput within model limits (up to ~70 bags/min depending on product).
• Lower film cost versus pre-made pouches for large production runs.
• Food-contact parts in stainless steel (304) compliant with food safety practices.
• Modular design for straightforward maintenance and cleaning.
• Customizable configuration to match product, bag size and line integration requirements.

Note
The delivered packaging unit typically includes the VFFS main unit, multi-head weigher, Z-type elevator, weighing platform and finished product conveyor.
