Product Overview

The Keypack Intelligent KL8-260 8-Station Pouch Feeding Machine for Pre-made Bags is a high-speed automatic pre-made pouch filling and sealing machine designed for flexible food packaging applications. It is suitable for packaging coffee, frozen foods, biscuits, cereals, nuts, confectionery, powders, granules, pastes, and selected liquid products.

The machine supports multiple filling configurations, including auger fillers, linear weighers, and multi-head weigher packing systems, making it an ideal solution for manufacturers seeking a versatile pre-made bag packaging machine. Compatible with stand-up pouches, zipper bags, and other pre-formed bags, the KL8-260 improves production efficiency while reducing labor costs and material waste.

Key Features and Machine Characteristics

• 8-Station Rotary Indexing Design
  The 360-degree rotary indexing structure allows all 8 stations to operate independently. If bag opening fails, filling and sealing are automatically stopped, effectively preventing bag waste. This design avoids the chain-reaction shutdowns common in linear pre-made bag packing machines.

• PLC Touch Screen Control with Rapid Changeover
  Equipped with PLC touch screen control, the KL8-260 enables simultaneous adjustment of all stations within approximately 5 seconds. Bag size changeover is tool-free, eliminating the need for wrench-based sequential adjustments and supporting frequent daily specification changes.

• High-Strength Integrated Bag Clamping System
  The integrally molded, corrosion-resistant claws feature a dual-material structure combining stainless steel and rubber. Withstanding up to 5 kg of pulling force, they securely grip bags during powder, granule, liquid, and paste filling, avoiding vacuum suction instability in dusty or moist environments.

• Advanced Bag Opening System
  A German Festo vacuum system supports dual bag opening modes, including synchronized top-bottom opening for stand-up pouches and compressed air inflation, ensuring stable and efficient bag handling.

• Premium Mechanical Construction
  Manufactured with Japanese-grade steel and precision cam mechanisms processed through advanced manufacturing techniques, the machine delivers long service life, stable performance, and reliable continuous operation.

• Washdown-Friendly Hygienic Design
  The monolithic chain-mounted tabletop features arc-shaped water channels. Electrical controls are cantilever-mounted and structurally separated from mechanical components, enabling full machine washdown and easy cleaning.

• Multi-Stage Dust Removal System
  A four-stage dust removal system is applied at the feeding area, mixing zone, motion track, and bag mouth. The variable-frequency industrial dust collector offers adjustable airflow levels via the touchscreen and uses high-efficiency PE+PTFE washable filters with programmable pulse-jet cleaning.

• High-Precision Sealing Performance
  The Japanese Omron temperature control system, combined with dual-knife opposing sealing and hot–cold sealing design, maintains a temperature deviation within ±1°C. Instant heat sealing and bag mouth dust removal ensure clean, firm, and visually appealing seals.

• Reliable International Components
  Electrical components from Siemens, Schneider, and Omron, along with high-performance bearings from Igus and TEK, ensure stable 24/7 operation, corrosion resistance, and extended service life in demanding production environments.
