Product Overview

The Keypack Intelligent KL8-200 8-Station Pouch Feeding Machine for Pre-made Bags is a fully automatic pre-made pouch packaging machine integrating a multi-head weigher and auger filler system. It is designed for high-speed, high-accuracy packaging of a wide range of materials including snacks, nuts, powders, granules, liquids and pastes.

This automatic bag feeding machine is suitable for various pre-made bag types such as stand-up pouches, zipper bags and flat pouches. Widely applied in the food, chemical and pet food industries, it helps manufacturers improve packaging efficiency, reduce labor costs and ensure stable, continuous production.

Key Features and Machine Characteristics

• High-Quality Structure
  Manufactured with Japanese high-quality steel and precision cams processed through 24 Japanese machining procedures, ensuring long service life and stable performance.

• Ultra-Fast Changeover with PLC Control
  Equipped with PLC touch screen control, all 8 stations can be adjusted simultaneously within 5 seconds, enabling quick bag size changes without tools—far more efficient than traditional linear pouch packing machines.

• Advanced Bag Gripping System
  Integrally formed bag claws with stainless steel and rubber dual-side design can withstand up to 5 kg tension, preventing bag slipping or dropping even in dusty, granular or liquid filling environments.

• 360° Rotary Indexing Design
  The 8-station rotary pouch packaging system allows independent operation of each station. If bag opening fails, filling and sealing are automatically stopped, reducing pouch waste and improving production reliability.

• Stable Bag Opening System
  Uses German Festo vacuum technology with dual opening modes (vacuum opening + compressed air blowing), ensuring reliable opening of stand-up pouches and zipper bags.

• Washable Hygienic Design
  The machine table features an integrated chain plate and arc-shaped water tank, while the electrical cabinet adopts a cantilever structure separated from the mechanical system, allowing full wash-down and easy cleaning.

• Four-Stage Dust Removal System
  Includes dust removal at feeding, hopper, movement track and bag mouth. A variable-frequency industrial dust collector with PE+PTFE high-efficiency filters ensures excellent dust-proof performance for powder and fine granule packaging.

• High-Precision Sealing System
  Equipped with a Japanese Omron temperature control system, double-knife opposing sealing and hot–cold sealing design maintain temperature accuracy within ±1°C, producing firm and visually appealing seals.

• Premium Electrical & Mechanical Components
  Uses international first-line brands such as Siemens, Schneider, Omron, Igus and TEK, ensuring 24-hour continuous stable operation and extended service life (3–5 times longer than standard bearings).

Application Areas

This automatic pre-made pouch filling and sealing machine is suitable for packaging:

• Food products: snacks, nuts, candy, coffee beans, seeds, pet food

• Powders & granules: milk powder, seasoning, chemical powder, sugar, granules

• Liquids & pastes: sauces, liquid additives, semi-fluid products

It is an ideal solution for manufacturers seeking a high-speed packaging machine, multi-head weigher packing machine, or premade pouch fill and seal system with high accuracy, hygiene and flexibility.
