Poly Bag Packing Machine 1–50ml (Three-Phase) — Product Introduction
The Poly Bag Packing Machine 1–50ml (Three-Phase) is an automatic sachet packaging solution engineered for high-efficiency, multi-lane production. It integrates film forming, accurate dosing, and stable sealing into a compact, production-ready system, enabling manufacturers to package small portions with consistent appearance and reliable seal integrity. With a maximum film width of 450mm and a dosing range of 1–50ml, the machine is ideal for single-serve packs, samples, trial sizes, and small-dose additives where speed, repeatability, and clean sealing are essential. Depending on the selected dosing configuration, it can handle particles, powders, and liquids, supporting diverse product lines while maintaining controlled film tracking and standardized safety protection for operator-friendly operation.
Product Features
Professional sealing performance with consistent pouch aesthetics
The horizontal sealing structure delivers an 8–10mm single-sided diagonal mesh pattern (1mm spacing) to enhance seal strength and provide a uniform, premium finish. The back seal is kept clean with a 4–6mm pattern-free design, improving readability of printed film and overall package appearance. The machine adopts twisted-edge adhesive sealing, helping maintain sealing reliability across common packaging films and varying product characteristics.
Wide dosing range for versatile single-serve packaging
Covering 1–50ml, the machine supports common small-format applications such as samples, concentrates, seasonings, daily-use portions, and functional additives. Material compatibility can be configured for particles, powders, or liquids to match production requirements and product behavior.
Accurate motion coordination for stable, repeatable output
A motor crank type heat-sealing bag pulling mechanism works in combination with encoder-controlled sealing actions, ensuring synchronized timing between pulling, cutting, and sealing. This design improves repeatability, reduces film deviation risk, and supports stable output across continuous operation.
Reliable electrical architecture with service-friendly components
Core electrical parts adopt recognized brands such as Schneider or OMRON, supporting long-term stability, easier maintenance, and consistent control performance—especially important for multi-shift production environments.
Safety-focused design for compliant operation
Standard safety configuration includes three-color alarm lights, Panasonic safety door detection switches, emergency stop switches, and clear safety labels at heating and mechanical motion areas. These measures help reduce operational risk, improve visibility of machine status, and support safer daily production management.
Consumer-friendly easy-open options
To improve user experience without compromising seal strength, the machine can be equipped with an independent easy-tear device, offering either a point-shaped easy-tear mouth or a double easy-tear mouth for smoother opening performance in retail and sample-use scenarios.
