Modern production machines allow extremely thin films to be manufactured at ever higher production speeds.
Conventional, undercut lamellae spreaders lead to local overstretching of the sensitive substrate, which can lead to wrinkling during further processing.
Problems in brief:
- Local overstretching of sensitive foils by lamellae spreaders
- of thin substrates with low inherent stability, recovery of the deformed lamellae and re-adjustment of the wrinkling in the substrate.
MITEX SoftSpreader: Offers good spreading and web guiding properties, even with small web tensions without overstretching the film locally
