Bags big and small: No sealing order is too tall!

The fastest of our polystar® continuous rotary band sealers can manage 10 m/min, but the standard speed of 5 m/min is not exactly slow. Its universal usability makes it an indispensable tool for when polyethylene bags up to 0.60 mm thick need to be sealed against air, dust and water in quick succession.

All polystar® continuous rotary band sealers of the 350 DSM series are continuously heated and have spring-mounted cooling rails that are automatically set to the relevant film thickness. This guarantees a constant pressing pressure, which in turn guarantees constant sealing results with a 4 mm wide seam. While the standard polystar® 350 DSM variant is suitable for lightweight pouches of up to 150 g, the TE variant can cope with bags weighing up to 500 g entirely on its own. Heavier bags of up to 25 kg can also be reliably sealed with the help of a roller track or conveyor belt, for example.

We know that packaging comes in all shapes and sizes – which throws up new challenges for you and us every day. Our answer to this is our practical modular system. Combine any of the following machine variants to create a sealing machine that meets your precise specs:

All variants of the continuous rotary band sealers can additionally be fitted with work aids. We offer the following work aids:

Our continuous rotary heat sealers from the 400 and 620 DSM series are perfect for sealing composite film bags.
