Nano, micro perforation or surface treatment of substrates and diverse running websMaterial webs such as cigarette-, mouthpiece tipping paper, filter-, coated special papers, force papers, bag papers or packing papers, bonded fabrics, spun bonded non-woven, technical textiles, fabrics, laminate, etc. with base weights from 20 g/m2 to up to 150 g/m2, up to 20 g/m2 LPDE coating films, are perforated electro-statically – ESP – nano/micro or laser or mechanical micro or macro for different application purposes. For a better comprehension: Electrostatic NANO/MICRO PERFORATION are statistically irregularly distributed, varying by size up to 40 %, and analogically, under LASER or micro/macro mechanical PERFORATION, evenly arranged in diameter about the same in size, at best non-inclined holes und rows of holes of diverse arrangement. For the human eye invisible electrostatic nano or micro perforations may be arranged in areas as well as in zones with specific distances within its web. The sizes of the holes range from 1 to 120 um in diameter and hole sequences from 1.5 to 16 million pores per second. Arrangements of zones are usually carried out in width from 2 to 6 mm and pore density of 15 to 250 pores per cm2 whereas the perforation of areas results in pore densities of up to 2 million pores per m2. ESP perforations allow for porosity levels from 80 to 2500 C. U., width of webs from 100 to 2000 mm at web speeds of up to 500 m/min, depending on the porosity and material consistency in relation to its ability to perforat
