Diversity is our strength: We can do it!

The specialist for composite materials! Whether aluminum or paper composite: These permanently heated polystar® Continuous welding machines of polystar® 400 and 620 DSM series seal all composite materials such as aluminum composite films or paper composite films firmly together: airtight, aroma-tight and dirt-proof.

The continuous heating and the robust construction of the polystar® Continuous sealing machines enable trouble-free continuous use, e.g. in V2A version for the food sector, for aroma sealing, for sealing cardboard tab labels, etc. Coated paper or aluminum bags up to a thickness of approx. 0.80 mm receive the necessary sealing seam security thanks to the spring-loaded embossing rollers. The extremely quiet stepper motor ensures a pleasant working environment. The sealing processes of the polystar® The 400 and 620 DSM series are therefore barely audible, but still provide a visibly good sealing result.

The difference between the polystar® Continuous sealing machines from the 400 DSM series and the 620 DSM series can be seen at a glance: the bag is fed upright in the 400 DSM series and lying down in the 620 DSM series. In addition, the 620 DSM series is available in V2A as standard.

The standard continuous sealing machine of the 400 and 620 DSM series can be used universally. Regardless of whether the composite film has to be sealed twice (two layers) or four times for side-gusseted bags, the polystar® Continuous welding machines with 6.7 meters per minute can do this!

We are aware of the variety of packaging options. Therefore, we have special solutions for you in the area of polystar® Continuous welding machines of the 400 and 620 DSM series:

• polystar® 400/3 DSM with 3 meters per minute for particularly thick barrier films, also with side fold
• polystar® 400/6.7 DSM-H: Seal at standard speed up to 80 mm below the edge of the bag. Ideal for bags with handles, for example
• polystar® 400 DSM with speed control. Simply adjust the speed to suit different bag materials and thicknesses.
• polystar® 400/6.7 DSM with precise temperature control. Some materials are very temperature-sensitive, e.g. polypropylene films or polyamide/polyethylene composite films. Here, the sensitive temperature sensor ensures a fluctuation-free temperature and thus a perfect sealing result.
• polystar® 400/6.7 DSM-V with extended and driven V-inlet. This special machine works particularly well in conjunction with a driven table conveyor belt or a large mobile conveyor belt. Simply place the filled stand-up pouch on the conveyor belt. The conveyor belt automatically transports the pouch through the V-inlet into the sealing area of ​​the rotary sealing machine. The pouch is sealed as soon as it comes out of the sealing machine.
• polystar® 400/6.7 DSM Zipper. Seal bags with zip fasteners, e.g. Doypack bags, in one operation and close the zip fastener - it couldn't be easier. We respond to the different heights of the zippers (distance from the edge of the bag) with different equipment for the zipper continuous sealing machine.
• polystar® 620 DSM with 6.7 meters per minute and precise temperature control seals all composite bags lying down with a 12 mm corrugated embossed seam.
• polystar® 620 DSM-HC with smooth embossing rollers effortlessly seals cardboard tabs with PE inner coating onto the bag. This continuous sealing machine is also equipped with precise temperature control.
• Usually all polystar® Continuous welding machines from right to left. If required, it can also be done the other way round: from left to right.
• The continuous welding machines of the 400 DSM series have powder-coated side panels. These side panels can of course also be replaced with V2A panels if required. This means that these machines can also be used in the food industry without any problems.

Important: The polystar® 400 DSM, 620 DSM and 620 DSM-HC are for polyethylene bags not suitable!

Our heat impulse sealers or the fast continuous sealers of the 350/5 DSM series are suitable for sealing polyethylene bags or polyethylene film.
