Vertical Form-Fill-Seal Machines offer ultrasonic welding option.

Press Release Summary:

Featuring stainless steel construction, color touchscreen panel, and Allen-Bradley MicroLogix PLC control system, Mercury HS forms, fills, and seals bags from 1.75–11 in. wide and 2.5–15.00 in. long at rates up to 140 bags/min. Ultrasonic welding, which seals multi-layer constructions as well as polyethylene, can increase throughput and quality and lower material/energy consumption. Self-centering film drive down system and automatic edge guide film tracking promote precise film movement.

SAUKVILLE, Wis. – Matrix Packaging Machinery, powered by Pro Mach, showcases a new ultrasonic welding option for its Mercury HS vertical form-fill-seal machines for the first time at Pack Expo Las Vegas, September 28-30. Since ultrasonic welding uses low, localized heat it’s ideal for frozen foods, produce, candy, dairy products such as cheeses, and other heat sensitive items. (Matrix Booth C-3323)

Ultrasonic welding applies precise ultra-high-speed vibrations along a seam. Friction along the edges of the internal layers of a bag generates heat, which melts and bonds the innermost layers. Ultrasonic welding is quick and precise, forming a high quality seal with superior mechanical strength. Less energy is consumed with ultrasonic than conventional sealing for lower operating costs. If the machine stops with the jaws on a bag, there is no risk of overheating.

In many applications throughput will be higher than ordinarily achieved, not only because the process is faster, but also because there is practically no dwell time required to cool the seam. High speed vibrations clear away or make irrelevant small particles of product adhering to the inside of the bag near the seam. Ultrasonic welding seals most multi-layer constructions, as well as polyethylene used for frozen food bags.

At start up, the first bags through are sealed properly, unlike heated clamping jaws, which may take a few cycles to achieve optimum temperature. Precision sealing also means less overall film consumption. Sealing jaws remain cool with less debris adhering to the surface of the jaws for more hygienic conditions. Operators can access the jaws quickly with no wait for cool down should maintenance become necessary.

The Mercury HS forms, fills, and seals bags with widths ranging from 1.75 to 11 inches (44 to 280 mm) and lengths from 2.5 to 15.00 inches (63.5 to 381 mm) at speeds of up to 140 bags per minute. Standard features include stainless steel construction, color touch screen operator panel, English/Spanish operator interface, and an Allen-Bradley MicroLogix PLC control system. Compared to other high speed machines, the Mercury has a small footprint, which helps to conserve valuable floor space.

Each Mercury HS offers a self-centering film drive down system, automatic edge guide film tracking, and short travel, angled incline film upwind, all of which contribute to precise film movement and trouble free operation. Tool-free quick-change core chucks help to ensure fast changeover between jobs.
