Packmate’s multi-head weighing & vertical form-fill-seal (VFFS) packaging machine combines dosing, bag forming, filling, sealing, and cutting into one streamlined solution for automated production. Built around PLC control with an intuitive touchscreen HMI, the system coordinates multi-head combination weighing and servo-driven film pulling to deliver stable output, clean bag appearance, and repeatable weight accuracy. The main contact parts are manufactured from hygienic 304 stainless steel, with a structure designed for easy cleaning and fast access, helping users meet common food and pharmaceutical workshop requirements. With automatic film tracking, selectable back-seal or side-seal structures, and adjustable bag dimensions, the machine adapts efficiently to different products, different bag styles, and frequent SKU changes—while maintaining consistent, high-speed performance and reduced downtime through its modular, maintenance-friendly layout.
Product Introduction
This integrated multi-head weigher packaging line is engineered for packaging powders, granules, snacks, and small solid items with high efficiency and minimal giveaway. Multiple weighing heads work simultaneously to calculate the best combination weight in real time, then discharge accurately into the formed bag. The packaging module completes precise film positioning, bag forming, longitudinal sealing, horizontal sealing, and patterned cutting in a continuous cycle. Operators can manage recipes, bag length, sealing temperature, pulling speed, and alarm prompts from the touchscreen, enabling quick commissioning and reliable day-to-day operation. The result is a compact, automated solution that improves yield, reduces manual handling, and enhances overall packaging consistency.
Product Features
High Accuracy & Stable Weighing Performance
The multi-head combination weighing system is designed to keep portion weights consistent across a wide range of flow characteristics. Precise control of feeding, weighing, and discharge helps minimize overfill, reduces material waste, and supports cost control—especially on high-value ingredients. Stepper-motor-driven weighing and integrated control logic maintain repeatability during continuous production, even when packaging speed increases.
High Output with Continuous, Automated Cycling
With simultaneous weighing across multiple heads, the machine achieves high throughput while keeping cycle time stable. Servo belt-driven bag pulling improves tracking accuracy and supports faster production with less film deviation. Depending on product properties and bag specifications, output can reach high-speed operation suitable for modern lines and batch runs, reducing reliance on manual intervention and frequent stops.
Flexible Bag Styles and Easy Changeover
The packaging section supports multiple bag formats such as pillow bags, gusseted bags, and four-side seal options (depending on configuration). Bag size adjustments, film width range, and selectable sealing structures allow the same equipment platform to cover different packaging needs. Recipe-based parameter storage on the HMI further shortens changeover time when switching between products and formats.
Hygienic 304 Stainless Steel Construction
Product-contact components made of 304 stainless steel support sanitary production and simplify cleaning. The equipment layout emphasizes accessibility and serviceability, helping teams perform routine inspection, cleaning, and parts replacement efficiently, while reducing downtime and maintaining stable output quality.
Reliable Control System and Film Tracking
PLC control and photoelectric color mark detection enable accurate registration for printed films and stable bag length control. Operators can select color mark tracking or touchscreen-based settings, improving packaging consistency for both plain and printed films. Integrated alarms and parameter protection help reduce operator error and improve operational reliability.
