Tipping, cigarette paper for high grad ventilation of cigarette filters
bernado
ventilation of non filter or filter cigarettes to create a directed
and guided air bypass. For this purpose, cigarette paper for some non
filter cigarettes and almost every kind of filter cigarettes tipping
papers are perforated electro-statically ESP OFFLINE and in zones from
2.0 - 6.0 mm width or rows ONLINE or OFFLINE by the use of lasers in
order to reduce the harmful substances such as nicotine and condensate
down to allowed values. Another effect is the possibility of guiding
and controlling the degree of ventilation of the Cigarettes.
Special applications and product properties with ESP electrostatic
perforation
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 impermeability will be found at the application stage of the
ELECTROSTATIC NANO/MICRO PERFORATION TECHNOLOGY.
Which means pore sizes from 0.5 up to 10 µm diameter by up to 5
million per m2.
This is due to the water's greater surface tension which hampers the
permeation through the relatively small nano or micro pores. These and
other physical advantages of the relatively small pores necessarily
demand the application of the ESP perforation method because
alternative perforation or processes are NOT feasible, too expensive
or simply uneconomical and would not lead to a successful application.
For a better comprehension: Electrostatic - ESP - 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 - ESP - 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 µm 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 perforate.
