IN Brief:
- BW Packaging has introduced the Hayssen X650 bottom-fed flow wrapper for cheese and hygiene-sensitive foods.
- The machine combines long-dwell sealing, full washdown construction and jaw protection when product positioning is incorrect.
- A maximum rated output of 150 packs a minute is accompanied by recipe settings, RFID login and an optional downstream reject system.
BW Packaging has introduced the Hayssen X650, a bottom-fed flow wrapping machine designed for cheese producers and other food manufacturers whose packaging operations require close control of seal integrity and hygiene. The machine combines long-dwell sealing with full washdown construction and automatic jam detection. Its stated maximum operating speed is 150 packs per minute, although practical output will depend on the product, package and line configuration.
The machine joins the Hayssen X850 in BW Packaging’s flow wrapping range. Cheese production is its principal target, although the manufacturer also identifies individually quick-frozen foods and fresh produce as potential applications. Products in these categories differ in size, moisture and handling temperature, which affects how film is formed and sealed around them. The choice of packaging material and operating recipe must therefore follow the food being wrapped and the conditions in which the finished pack will be distributed.
During flow wrapping, film travels continuously around the incoming product and is closed through longitudinal and transverse seals. The X650’s bottom-fed configuration sets how product and film are presented to the wrapping section. Seal formation depends on the film structure, jaw temperature, pressure and contact time, while product position determines whether the end seal can close without obstruction. These variables must be set together to prevent damaged product or incomplete closures during production.
Long-dwell jaws provide a longer sealing contact period than shorter-dwell arrangements, supporting the formation of hermetic seals in demanding applications. That capability has to be balanced against film selection and operating speed. A suitable sealing recipe is established through checks of the intended package rather than the machine rating alone. The X650 is specified for speeds up to 150 packs a minute; effective output is governed by pack dimensions, feeding consistency, sealing requirements and how the rest of the line handles completed packs.
The X650’s jam detection system responds when a product is not correctly positioned as it approaches the transverse sealing jaws. The jaws open before contact, reducing the risk of crushing the food or contaminating the sealing area. The machine can subsequently create a double-length pack and track it to the downstream point where an optional reject system removes it. This sequence separates the protective action at the sealing head from the disposal of the affected package.
Where the optional reject unit is installed, the control system can maintain the identity of that affected pack as it travels out of the wrapper. Downstream conveyors and removal equipment must be configured to act on the signal at the correct position. Without the reject option, the protective opening of the jaws still occurs, but the manufacturer must provide another suitable method to identify and handle the non-conforming pack. This distinction is important when specifying a complete inspection and packing line.
Cheese products can vary in shape and position as they move through an infeed, leaving sealing jaws exposed to occasional misplaced items. When the system opens its jaws before contact, it can limit product damage and material transferred into the sealing area. The actual reduction in rejects will depend on product presentation, film and downstream handling. A processor commissioning the wrapper will need to check the frequency of positioning faults and confirm that affected packages are removed from the saleable product stream.
The X650’s full washdown construction addresses sanitation requirements in hygiene-sensitive production areas. Cleaning procedures still need to reach product-contact components and nearby surfaces without damaging controls, bearings or other equipment. Detergent compatibility, washdown methods and inspections are established under the site’s hygiene plan and the machine’s operating specifications. This makes access for cleaning and the ability to return the machine to production important parts of its daily operating cycle.
Recipe-driven settings, RFID login and the OpView human-machine interface support controlled operation and changeovers. Stored parameters can help operators switch between packaging formats and inspect fault conditions, while individual logins structure access to machine controls. Recipe selection must still be matched to the actual product and film: the feed, web forming, sealing temperatures and downstream equipment need appropriate settings for a stable run after the changeover.
The combination of long-dwell sealing, position sensing and full washdown construction is intended to support consistent wrapping in cheese and related food applications. On an installed line, performance will be determined by how the infeed presents products, whether the film achieves the required seals and how the reject and cleaning procedures are integrated. Those operating conditions, rather than the maximum mechanical speed in isolation, establish the sustained rate of conforming packs leaving production.
