Product Introduction
The DS450-4G/P/L Automatic Bag Packing Machine is a multi-lane pouch forming, filling, and sealing solution designed for high-efficiency small-dose packaging. Built for particles, powders, and liquids (configured according to product requirements), it combines stable film pulling with precise sealing control to deliver consistent pouch quality. For liquid applications, the machine produces a horizontal sealing leak-proof line up to 1 mm, supporting reliable pack integrity. With a 1–50 ml dosing range and flexible lane configuration, it is well suited for mass production of single-serve and sample-size sachets where speed, repeatability, and safety compliance are essential.
Product Advantages
Reliable Sealing for Liquid and Non-Liquid Products
The twisted-edge adhesive sealing structure helps create firm seals across a wide range of packaging materials and product types. For liquid packaging, the horizontal sealing design supports enhanced leak resistance with a dedicated leak-proof line specification.
Stable Film Handling and Accurate Sealing Control
A motor crank-type heat-sealing bag pulling system, paired with an encoder that controls sealing action, ensures synchronized motion between film pulling and sealing. This improves pouch consistency, reduces mis-seals, and supports continuous high-speed production.
Clean Cutting and Professional Pack Appearance
Round-corner cutting with an independent cutting device delivers neat edges and a premium look while minimizing waste to approximately 2–3 mm per cut, helping reduce film loss over long production runs.
Flexible Multi-Lane Output
The machine supports 4–9 columns (lanes), selected based on pouch size. This multi-lane format increases throughput without sacrificing seal quality, making it suitable for scale-up and varied SKU planning.
Enhanced Safety Configuration
Standard safety provisions include three-color alarm lights, Panasonic safety door detection switches, and an emergency stop switch. Heating zones and mechanical action positions are required to be clearly marked with safety signage, supporting safer daily operation and maintenance.
