Low-Pressure Heat Sealer NDS
 |
Low-Pressure Heat Sealer NDS… allows you to determine the sealability of films and provides five temperature independent sealing stations.

How it works
The Low-Pressure Heat Sealer NDS allows you to determine the sealability of coated paper, aluminium foils and laminates as well as other heat-sealable multi-layer films.
You can easily determine the optimum sealing parameters for any film types used for pressure-sensitive charge with appropriate packaging machines.
The NDS simulates the low-pressure heat sealability under real-life conditions. The two key sealing parameters – temperature and time – can be exactly set at the NDS.
Using the standard set of weights (5 x 214 g) the NDS operates with a sealing pressure of 0.35 N/cm². This sealing pressure corresponds to real-life circumstances during the packing process for pressure-sensitive goods. The special construction of the set of weights guarantees exact parallelism and an evenly distributed sealing pressure across the entire sealing area at all sealing units. The five separately adjustable and self-optimising PID temperature controls ensure a high exactitude of the selected sealing temperatures. Therefore, the NDS ensures an excellent reproducibility of your tests.
