Size doesn't matter: We'll take it all!

Large and heavy bags and sacks, filled with, for example, free-flowing products, can be filled with these polystar® The bags and pouches are perfectly sealed using heat sealers. The horizontal arrangement of the heating element supports allows the bags and pouches to stand upright during sealing. This means that none of your product can leak out.

Add a pallet truck to these double-heated pulse welding machines, and you have a perfect packing station. polystar® The 400 HM series foil sealing machine is placed on the height-adjustable work platform of the pallet truck. An integrated, also height-adjustable, roller conveyor beneath the work platform ensures easy feeding of the bags or sacks between the horizontal heating element carriers. Now simply trigger the sealing pulse with the foot pedal – done!

The 400 HM series of heat sealers is available in working widths from 400 mm to 1,000 mm. Depending on the working width, the front heating element carrier is held in place by two to four sturdy spacers positioned approximately 30 mm above the heating element carrier. This also means that there is an automatic upper limit to the bag feed – the distance from the bag edge to the sealing seam can therefore only be 30 mm.

What if you need more distance between the bag edge and the seal? Just let us know, because we naturally have a solution for that too: The heating band supports are mounted on a U-profile. This gives you more flexibility without compromising on a reliable seal. The only thing you then need to decide is from which side the bags or sacks should be fed in – from the right or the left.

The polystar® The 400 HM series foil sealing machines are just as reliable and durable as comparable models. polystar® 400 M-series foil sealing machines with vertical heating band carriers:

• Robust construction
  Dual heating, automatic welding and cooling time control, a foot switch, and a robust housing complement each other perfectly. This combination allows for the reliable welding of many types of film up to 2 x 0.40 mm thick.
• Comfortable working
  The sealing process can be conveniently triggered by the foot pedal. This leaves your hands free so you can prepare the next bag or sack for sealing while the sealing and cooling process is underway.
• Individual extra features
  Whether you want "room to grow" with the U-profile or "doubly secure" with a 2 x 3 mm double seam - we can of course fulfill these wishes for you.

Foil welding using the proven heat impulse method
Energy-efficient (from 0.8 kWh) and therefore environmentally friendly, because electricity is only consumed when the welding pulse is triggered. The heat pulse process also means there are no preheating phases. Simply switch on the power, set the welding and cooling time, and start welding.
