Products containing bonded fabrics, bag or packaging papers, non-woven, etc. with gas or steam permeability, ventilation, breathable BUT but water impermeability.
Further substrates or nano micro engineered membranes for micro filtration, fractionation, nanopattering, nanomembranes, nanophotonics, microbiology, medial, food, packaging, atmosthere, catalysis, gas, alcohol, liquid or blood separation, battery separator foils or others are possible with NANO MICRO ELECTROSTATIC OR MICRO LASER PERFORATION TECHNOLOGY, depends of material structures and perforability.
Which means pore sizes from 10 nm up to 10 um diameter by up to 5 million pores per m2. This is due to the water greater surface tension as dyne level and hydrophobic property or wetability through the relatively small sizes of nano or micro pores. These and other advantages of the pores necessarily demand the application of the ESP perforation method because alternative perforation or processes are physically NOT feasible, too expensive or simply uneconomical and would not allow successful product applications.
Further laser features
A patent pending Micro Laser Line perforation technology MLL-1 generates sinus, waves, zigzags or other kinds of perforations cryptograms, designs as multiple or quadruple pairs of micro laser lines in web direction. Hole, slot or star sizes in ranges from 60 up to 200 μm are possible. Provide for tipping, cigarette, packaging or other kind of paper, plastic film or other web material.
Special features of micro laser line perforation with new product characteristic in scripts, e.g. for mouthpieces with tipping paper, CTP on cigarette filters, product indication with visible perforation holes, brand name, company logo, indications, anti counterfeiting designs, cryptogram, etc.
