Keypack Intelligent Single Station Pouch Feeding Machine — premade pouch packing solution engineered for consistent, repeatable automated packaging across granules, powder, liquid, and sauce products. It delivers reliable output at 5–10 bags per minute with broad pouch format compatibility and a compact, integration-ready footprint. Ideal for food, pharmaceutical, chemical, and agricultural production lines requiring flexible pre-made bag packaging without high capital investment.
Product Overview
The Keypack Intelligent Single Station Pouch Feeding Machine is designed for small to medium-scale production lines that need a dependable, versatile premade pouch filling machine without the complexity of high-speed rotary systems. It accommodates four major pouch styles — stand-up pouches, four-side seal bags, three-side seal bags, and pillow bags — across a wide size range (width 200–400mm, length 200–500mm), making it suitable for a broad spectrum of product categories and packaging formats.
This premade pouch packing machine handles a diverse range of materials: free-flowing granules such as coffee beans, rice, and seeds; fine and coarse powders including flour, spice blends, protein powder, and detergent; viscous liquids and pourable sauces such as chili sauce, ketchup, and cooking oil; as well as irregular solid products like frozen dumplings, cookies, and snack pieces. The machine is not recommended for highly hygroscopic powders with moisture content above 8% or for materials requiring sterile filling environments without additional clean-room configuration.
Operating on standard electrical supply (1.2 kW / 220V / 50–60Hz) with moderate compressed air requirements (0.8 MPa, 0.6 m³/min), the Keypack Intelligent (Kunbupack) Pouch Feeding System integrates smoothly with upstream filling equipment — auger fillers, volumetric cups, piston fillers — and downstream conveyors or case packers, enabling a complete, scalable end-of-line packaging solution.

Key Features and Machine Characteristics
1. Versatile Premade Pouch Compatibility
Supports four major pouch formats across a wide size range (width 200–400mm, length 200–500mm), enabling packaging from small single-serve sachets to larger family-size pouches. Reduces the need for multiple dedicated machines and lowers capital investment for multi-product manufacturers.
2. Multi-Material Handling Capability
Engineered to handle granules (coffee beans, rice, seeds, pellets), powders (flour, spice blends, protein powder, chemical additives), liquid and sauce products (chili sauce, ketchup, cooking oil, beverage concentrates), and solid items (frozen dumplings, cookies, snack pieces). Quick changeover between material types minimizes downtime for contract packagers and multi-SKU producers.
3. Compact Single Station Design
The space-efficient footprint (1680mm × 510mm × 1500mm) and lightweight construction (150 kg) make this premade pouch packing machine well-suited for facilities with limited floor space, mobile packaging setups, or pilot production environments. Robust construction ensures reliable performance despite the compact form factor.
4. Straightforward Integration and Operation
Standard utility requirements (1.2 kW / 220V, 0.8 MPa compressed air) allow integration into existing production lines without major infrastructure upgrades. The mechanical design is accessible for operators without specialized technical backgrounds, reducing training time and simplifying routine maintenance.
5. Adjustable Packaging Speed
Output of 5–10 bags per minute can be tuned to match upstream filler capacity and downstream conveyor speed. Speed adjustment accommodates variations in film stiffness, material flow properties, and required seal dwell time, supporting consistent seal quality across different pouch materials and product types.
6. Cost-Effective Entry into Automated Pouch Packaging
Provides an economical pathway from manual to automated pre-made bag packaging for food, pharmaceutical, chemical, and agricultural producers. The combination of multi-format pouch compatibility, multi-material handling, and compact design delivers a strong return on investment for small to medium batch production without the capital expenditure of high-speed rotary systems.
