Product Overview

The Keypack Intelligent KL8-300 8-Station Pouch Feeding Machine for Pre-made Bags is a fully automatic pre-made pouch filling and sealing machine designed for high-speed, precise packaging of a wide range of products, including snacks, nuts, candy, powders, granules, pastes, and selected liquid products. The machine is suitable for stand-up pouches, zipper bags, and other pre-formed bags, offering stable bag feeding and efficient packaging performance.

Integrating a multi-head weigher packing system and an auger filler, the Keypack Intelligent KL8-300 supports flexible filling solutions for different material characteristics. It is widely applied in food, pet food, and chemical packaging industries, helping manufacturers improve production efficiency, reduce bag waste, and lower labor costs through reliable automatic operation.

Key Features and Machine Characteristics

• 8-Station Rotary Indexing Structure
  The Keypack Intelligent (Kunbupack) KL8-300 adopts a 360-degree rotary indexing design, enabling independent operation of all 8 stations. If bag opening fails, filling and sealing are automatically stopped, effectively preventing bag waste and ensuring stable production compared with linear pre-made bag packing machines.

• PLC Touch Screen Control with Fast Changeover
  Equipped with PLC touch screen control, all 8 stations can be adjusted simultaneously within approximately 5 seconds. Bag size changeover is tool-free, allowing fast switching between different pre-made pouch specifications and supporting flexible production schedules.

• High-Strength Integrated Bag Clamping System
  The integrally molded, corrosion-resistant claws combine stainless steel and rubber in a dual-material structure, providing strong gripping force to securely hold bags during powder, granule, liquid, or paste filling, reducing the risk of bag dropping.

• Stable Bag Opening System
  A German Festo vacuum system is used for bag opening, supporting synchronized upper and lower opening as well as compressed air inflation. This ensures reliable opening of stand-up pouches and zipper bags across different packaging applications.

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

• Hygienic and Washdown-Friendly Design
  The machine table features an integrated chain plate and arc-shaped water channels. The cantilevered electrical control structure is separated from the mechanical components, enabling thorough cleaning and washdown.

• Integrated Multi-Stage Dust Removal System
  A four-stage dust removal system is applied at the feeding area, hopper, movement track, and bag mouth. The variable-frequency industrial dust collector equipped with high-efficiency PE+PTFE filters provides effective dust control for powder and granule packaging.

• High-Precision Sealing Performance
  The Japanese Omron temperature control system combined with double-knife opposing sealing and hot–cold sealing design maintains temperature deviation within ±1°C, ensuring consistent sealing strength and clean bag appearance.

• Reliable International Components
  Electrical components from Siemens, Schneider, and Omron, along with wear-resistant bearings from Igus and TEK, ensure stable 24-hour operation and long-term reliability in demanding production environments.
