Product Introduction
The DS450-4G/P/L Automatic Bag Packing Machine is a high-output, multi-lane vertical form-fill-seal (VFFS) system engineered for small-dose sachet production. It integrates pouch forming, metering, filling, and sealing into one streamlined platform for particles, powders, and liquids (configured to match your product characteristics). Designed around stable film transport and precisely timed heat sealing, the machine delivers repeatable pouch geometry and dependable seal strength at production speeds suited to mass-market single-serve formats. For liquid packaging, a dedicated horizontal sealing design creates a defined leak-proof line up to 1 mm, helping protect pack integrity during handling, storage, and distribution. With a 1–50 ml dosing range and lane options tailored to sachet dimensions, the DS450-4G/P/L supports efficient scale-up for samples, trial packs, and retail-ready mini packs where consistency, safety, and productivity are non-negotiable.
Product Features
Seal Integrity Designed for Liquids, Powders, and Granules
A twisted-edge adhesive sealing structure enables firm, uniform sealing on common packaging films, supporting a wide range of product types. When configured for liquids, the horizontal seal includes a specified leak-proof line (up to 1 mm) to enhance resistance against seepage and improve package reliability.
Synchronized Film Pulling and Heat-Seal Timing
The motor crank-type heat-sealing bag pulling system, combined with encoder-controlled sealing action, keeps film movement and sealing cycles aligned. This synchronization improves sealing stability, reduces misalignment and partial seals, and helps maintain consistent sachet length and finish during continuous high-speed operation.
Neat Round-Corner Cutting with Low Film Waste
An independent cutting device performs round-corner cutting to create clean, professional-looking edges while controlling waste to approximately 2–3 mm per cut. This helps reduce cumulative film loss over long runs and supports better presentation for retail and promotional sachets.
Multi-Lane Architecture for High Throughput
The machine supports 4–9 lanes (columns), selected according to sachet size requirements. This multi-lane output increases overall productivity without compromising seal quality, making it ideal for manufacturers managing multiple SKUs or expanding capacity for high-volume, small-format packaging.
Safety-Focused Standard Configuration
Standard safety equipment includes three-color alarm lights, Panasonic safety door detection switches, and an emergency stop switch. Heating zones and mechanical action areas are required to be clearly labeled with safety signage, supporting safer operation, inspection, and routine maintenance.

Application Areas
The DS450-4G/P/L is built for industries requiring fast, consistent, and clean small-dose sachet packaging. Typical uses include liquid sample packs and single-serve portions, as well as powder, granule, and particle products that benefit from multi-lane high-speed output. It fits both food and non-food production lines, supporting trial-size sachets, promotional packs, and daily high-volume packaging with stable seals and a refined finished appearance.
