micro material cluster treatment

Material treatment and micro perforation in cluster systems
Web material as regenerated cellulose film, filter, cigarette, tipping, roll-your-own RYO, make-your own MYO, wall, decoration, transparent, coated, laminate, sack, bag or flexible packaging paper, bonded fabrics, spun bonded non-woven, food, fruit, medical, under roof house or agriculture vegetable covering, packs, technical textiles, fabrics, laminate with base weights 20 g/m2-180 g/m2, thicknesses 10-80 microns, up to 20 g/m2 LPDE coatings are perforate electro statically micro, or by laser with micro or macro holes for wide range of application purposes.

Technology
ELECTROSTATIC micro cluster perforation or other material treatment, based at micro discharging and sparking, plasma tunnel effects with gas atomic ionization in nano second time windows. The pores are normally statistical irregularly distributed in controlled size ranges from 0.05-80 microns diameter and analogically, under LASER or MICRO or MACRO PERFORATION, arranged in diameter sizes from 60-200 microns, at best non-inclined holes und holes rows of diverse arrangement comprehension.

For the
naked human eye invisible electrostatic micro perforations may be arranged in areas or zone bands with specific distances within its web. Controlled pore sizes in wide ranges from 0.050-80 micron diameters by holes sequences up to 16 million pores per second and 0.1-3 mill Joule discharge energy for each pore. That processes and power electronics are patent granted with DE10328937.

Performance

Arrangements of zones are usually carried out in width from 2 to 6 mm and pores density of 15 up to 250 pores per square cm whereas the perforation of areas results in pore densities of up to 5 million pores per m2 in surface-all-over design. Electrostatic perforations allows porosity levels from 80-2,500 Coresta Units (ml/min/2cm2 by 1,000Pa), equality from 40 down to 3 Gurley, by material web widths from 100-2,000 mm and at web speeds of up to 500 m/min, depending on porosity and material consistency in relation to its ability to perforate.

Physical Properties
One of the foremost postulation which can be applied to many application purposes and products containing bonded fabrics, bag or packaging papers, non-woven, etc. with gas or steam permeability but water in-permeability will be found at the application stage of the electrostatic micro cluster perforation. Which means pore sizes from 0.050-80 microns diameter by up to 5 million per square meter.

This is due to the water’s greater surface tension which hampers the permeation through the relatively
small micro pores. These and other physical advantages of the relatively small pores necessarily demand the application of the cluster perforation method because alternative perforation or processes are NOT feasible, too expensive or simply uneconomical and would not lead to a successful application.

Products, outstanding applications, advantages with micro perforation
breathable and ventilated mass products as cigarette, tipping, filter, flexible packaging, plug wrap
refinish or fine paper
booklet, bible, printing, magazine, promotion, flyers or newspaper with improved or modified surface property
decoration or gift paper with thin coating films
PVC laminate, Vinyl, decoration or wall paper to eliminate one side condensation effectsenable control gas exchanges, avoid rises of mildew or rottenness
joint or corner Kraft paper tapes to avoid glue bubbles and enables material diffusion
fleece bonded with thin plastic film layers for outdoor, under roof protection or covering, wooden
houses to enable gas exchanges
technical textiles for gas exchanges to avoid condensation processes
breathable overalls, heavy duty or disposable work dresses, trousers, aprons, jackets or shoes made of thin PE fleeces or others
thin PP or PE contacted Kraft paper bag, cement sacks, plaster, maize, grain, pet food, granulate or powder for gained air outlet or out blowing during filling processes with multiple time reduced efficiencykeep packed products in same barrier condition as without micro perforation
extending storage, live time or durability of certain goods and products

biotopes and prevention of water pollution
synthetic, real leather or cloth inlets for comfortable non sweat wearing under wet, high humidity and tropical condition
soap, deodorant, hygiene, beauty creams, baby care or other packaging products which needs smell
suggestion for marketing indication and buying advantages
food, vegetable or flowers with paper packaging replacements for gas and oxygen exchanges
bread, rolls, fruits or food to improves for freshness and aroma advantages
technical multi layer foils for industry, medical, bioengineering or filtration purposes, surface modification or improve the roughness
micro filter, membranes, battery separation layers, bio or lab analytic
alcohol, liquid or blood filtration, clean room, agriculture plant applications
reduction or force growth rates of bio processes

Differences and system integration
It is also used especially for additionally treating materials when aiming special characteristics by physical or regular process reasons what cannot be achieved by other process technologies. Moving material web base weights from 20-180 grams per square meters by thicknesses 10-80 microns are possible to use. Including defect inspection, process automation, moisture vapor transmission rate, abrasion resistance of lamination, water proof, ventilated or breathable fabrics.

Our state-of-the-art
industrially approved, sophisticated, compact, multi functional, optical online sensor scanning systems together with electrostatic or laser perforation technologies operates precise and reliable 24/7, are integrate able into existing rewinding, slitting, cutting, spooling, spreading, printing, labeling, multilayer sack, bag manufacturing or other complex production lines or other machines and processes as well.

Also, they can be used as completely independent offline surface-all-over or zone micro perforation
units. Fully new ranges of applications will be made available total new products with special features and properties.
