Matrix’s Mercury HS form-fill-seal machine



Matrix process for heat-sensitive items

The welding option, ideal for heat-sensitive food items, offers a faster process and higher throughput as well as better energy savings than conventional sealing

December 2015

Matrix Packaging Machinery, powered by Pro Mach, has introduced a new ultrasonic welding option for its Mercury HS vertical form-fill-seal machines. Since ultrasonic welding uses low, localised heat it’s ideal for frozen foods, produce, candy, dairy products such as cheeses, and other heat-sensitive items.

Explaining, Matrix said 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 and lengths from 2.5 to 15.00 inches at speeds of up to 140 bags per minute. Standard features include stainless steel construction, colour 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.
