The real strong point of long dwell is represented from the packaging possibility with very high speed:
unordinaryefficiency, that makes it recomanded on a big variery of contests and in particular for films that are difficult to seal. The bags after being cut by separator zig zag knife, they will be transfered directly on the delivery belt.

Another keyworth characteristic of a long dwell device is its resistance that permits to increase considerably the sealing time: thanks to the long contact between the sealing bars. This means that the seal is not only robust, but also more durable and also it is able to keep much more on time: It gives the technical name "long dwell".
A good hold on seals is keyworth preculiarity, but it should not be understimated also the long dwell versatility, that is available to different versions: over than the traditional type, there is also the version with rollers through cutting-head, the one with three or more sealing bars and the poly version, that allows the process of polythilene film. Considering a very used film on actual packaging processings (in virtue of its versatility and its low cost), the long dwell poly reveals almost fundamental.
