Product Overview
The Keypack Intelligent (Kunbupack) KG8-300 Pre-made Bag Filling Machine is an 8-station automatic pre-formed bag packager featuring advanced weighing technology and dust-proof design for large-format applications. This cup filling weighing machine integrates seamlessly with multi-head weighers to form complete automated packaging lines for wide bags ranging from 200-300mm in width. The machine supports stand-up pouches, handheld bags, four-side seal bags, three-side seal bags, paper bags, and composite bags, making it a versatile solution for food packaging machinery, pet food packaging machine, and chemical packaging line applications requiring larger bag formats.
Equipped with variable frequency speed control and automatic bag width adjustment via hand crank, the KG8-300 automatic pre-formed bag packager offers flexible operation for packaging from 10g to 2500g with optimized speed for heavier fills. The oil-free vacuum pump system with automatic bag feeding eliminates environmental pollution while maintaining reliable packaging efficiency at 10-35 packs per minute. All material contact parts are manufactured from 304 stainless steel, ensuring compliance with food hygiene standards and suitability for snack packaging equipment, agricultural product packing, and chemical packaging line applications.
This pre-made bag filling machine can be configured with vacuum feeding conveyors, screw dosing machines, horizontal screw conveyors, and screw feeding conveyors to create fully automated powder and granule packaging production lines for bulk pet food, large-format snacks, seeds, grains, and chemical granules applications.
Key Features and Machine Characteristics
1. User-Friendly PLC Control System
The automatic pre-formed bag packager features PLC control with HMI interface, enabling operators to monitor and adjust packaging parameters in real-time for large-format bag applications. This servo drive system enhances operational efficiency and reduces training time for new operators in food packaging machinery, pet food packaging machine, and agricultural product packing applications.
2. Variable Frequency Speed Control
Equipped with variable frequency drive technology, the volumetric cup filling machine allows speed adjustment from 10-35 packs per minute within specified ranges to match different material characteristics and heavier fill weights, optimizing throughput for bulk granules, powder, pet food, coffee beans, grains, and seeds applications.
3. Convenient Bag Width Adjustment for Large Format Bags
The automatic bag width adjustment system uses a hand crank mechanism, enabling quick changeover between different bag sizes from 200-300mm without tools. This feature is particularly valuable for manufacturers packaging bulk products on the same cup filling weighing machine, supporting diverse applications from large-format milk powder to pet food packaging and agricultural products.
4. Oil-Free Vacuum Pump with Automatic Bag Feeding
The oil-free vacuum pump system with automatic bag feeding eliminates the risk of oil contamination and environmental pollution, making this pet food packaging machine suitable for sensitive applications in food packaging machinery, snack packaging equipment, and agricultural product packing requiring clean operation.
5. Food-Grade Stainless Steel Construction
All material contact parts are manufactured from 304 stainless steel, meeting food hygiene standards and ensuring product safety for milk powder, pet food, coffee beans, snacks, seeds, and grains. This construction also provides corrosion resistance for chemical packaging line operations handling chemical granules and pharmaceutical powders in larger bag formats.
6. Integrated Automation Capability with Dust-proof Design
The KG8-300 pre-made bag filling machine features comprehensive dust-proof design and can be integrated with vacuum feeding conveyors, screw dosing machines, horizontal screw conveyors, and multi-head weighers to create complete automated packaging lines. This modular design supports diverse applications across food packaging machinery, chemical packaging lines, and agricultural product packing systems for medium to large-format bags.
