Description
FIELD
[0001] The present application concerns a cigarette filter having a
filtration material and a tipping film, more particularly a
biodegradable tipping film with excellent physical properties, in
particular with regard to elongation, tensile strength and
shrinkage, but also as far as flatness and tube/curl are
concerned.
BACKGROUND
[0002] There is a current demand for cigarette tipping films which
are transparent, allowing the smoker to view the effectiveness of
the filter material enclosed within the tipping film.
[0003] Certain biodegradable substrates have been considered for
use as cigarette tipping films. However, because of stringent
demands in the tobacco industry with regard to the chemical make up
of tipping films, and also with regard to their physical
properties, there is a need to provide an improved form of tipping
film which is substantially free from certain specified
contaminants and which has excellent properties as far as
elongation, tensile strength, shrinkage, flatness and tube/curl are
concerned. In particular, the mechanical tolerances of any such
film must be carefully controlled in order to allow the film
satisfactorily to be deployed in the machinery used by the tobacco
industry to wrap tipping papers around filter tips. Because of the
relatively small size of the unit film, and the necessity for it to
be tightly and neatly wound on the filter, it has proved difficult
to develop a filmic material, particularly one with other desirable
qualities such as biodegradability and transparency to meet these
criteria.
[0004] The present invention seeks to address these issues.
DETAILED DESCRIPTION
[0005] According to the present invention there is provided an at
least partially transparent cigarette filter tipping film
comprising a biodegradable substrate, and softener in an amount of
less than 25% by weight of the biodegradable substrate.
[0006] The biodegradable substrate is selected from biodegradable
substrates, PLA substrates, starch based polymers,
hydroxyalkanoates and other biopolymers, but is preferably a
cellulosic substrate.
[0007] The invention also provides a cigarette filter comprising a
filtration material encased in a cylinder of aforesaid tipping
film.
[0008] Preferably the tipping film is at least mostly transparent
so that the filtration material can be viewed through the tipping
film.
[0009] Preferably the softener is present in the tipping film in an
amount of less than 24% by weight, more preferably less than 21% by
weight and most preferably less than 18% by weight of the
biodegradable substrate.
[0010] The softener may be selected from any suitable material, but
is preferably selected from glycerol, propane-1,2-diol, and any
other suitable softener selected from the German Tobacco Ordnance
(TVO) list, the contents of which are hereby incorporated by
reference, and an English translation of which is reproduced as
appendix 1 hereto, and combinations of two or more thereof.
[0011] The tipping film itself will generally be cast and then
wound onto a reel prior to eventual unwinding and slitting for use
as a cigarette tipping film. In order to allow the film to be wound
onto a reel without sticking to itself, the substrate is preferably
provided with an antiblock/winding aid additive. When present the
antiblock/winding aid additive is preferably provided in an amount
of less than about 0.5%, more preferably less than about 0.4, even
more preferably less than about 0.3 and most preferably less than
about 0.2% by weight of the biodegradable substrate.
[0012] The antiblock/winding aid when present may be selected from
any suitable material, but is preferably selected from amorphous
silica, polyethylene glycol, and any other suitable
antiblock/winding agent selected from the TVO list, and
combinations of two or more thereof.
[0013] We have surprisingly found that by careful selection of the
quantity of softening agent in the tipping film, and in preferred
embodiments of the invention of the type of softening agent in the
tipping film, certain problems exhibited in the art with reference
to conventional biodegradable substrates can be avoided. For
example, certain conventional biodegradable substrates which would
otherwise be suitable as tipping films have been found to be too
easily elongated--a property which causes problems in the machinery
commonly used in the tobacco industry for rolling tipping materials
around cigarette filters. Certain conventional biodegradable
substrates have been found to be insufficiently flat, to exhibit
unacceptable levels of curl, to lack sufficient tensile strength
and/or to be too elastic, to be too susceptible to shrinkage and/or
to have inadequate optical properties.
[0014] The tipping films of the invention preferably exhibit an
elongation in the machine direction of less than 15%, more
preferably less than 13% and most preferably less than 11% when
subjected to standard testing conditions referred to herein in the
Examples.
[0015] The tipping films of the invention exhibit excellent
properties with regard to flatness and tube/curl. Preferably the
tipping films of the invention exhibit a flatness of less than
about 4 cm, preferably less than 3 cm and exhibit a tube/curl of
less than 45.degree., preferably 0.degree. once wound (Flatness is
measured by placing a 6 m length of cast film on a flatness table
and pulling the film until tight. Flatness is measured by using
graduated rulers, the results are recorded as, Flatness (cm)=Centre
reading (cm)-Edge reading (cm). Tube/curl Is measured by hanging
approx. 600 mm of cast film from a suspended mill roll, strips are
cut in the machine direction 100 mm apart across the width of the
roll, film is left to stand for 15-20 seconds, visual checks for
tube and curl are made and results are recorded in degrees.
[0016] It may also be important to maintain the tensile strength of
the tipping film in order to allow satisfactory machinability of
the film. Preferably the tipping films of the invention exhibit a
tensile strength in the machine direction of more than 140 MPa,
more preferably more than 150 MPa and most preferably more than 155
MPa when subjected to standard testing conditions referred to
herein in the Examples.
[0017] It may also be important to maintain the elasticity of the
tipping film in order to allow satisfactory machinability of the
film. Preferably the tipping films of the invention exhibit a
Young's Modulus in the machine direction of more than 4000 MPa,
more preferably more than 5000 MPa and most preferably more than
5500 MPa when subjected to standard testing conditions referred to
herein in the Examples.
[0018] It may also be important to ensure that the tipping films of
the invention do not exhibit too high a shrinkage, in order to
allow satisfactory machinability of the film. Preferably the
tipping films of the invention exhibit a shrinkage under tropical
conditions in the machine and/or transverse directions of less than
5%, more preferably less than 4% and most preferably less than
3.75% when subjected to standard testing conditions referred to
herein in the Examples.
[0019] It may also be important to maintain the optical properties
of the tipping film. Preferably the tipping films of the invention
exhibit a Haze of less than 2.15, more preferably less than 2.10
and most preferably less than 2.05 when subjected to standard
testing conditions referred to herein in the Examples. Preferably
the tipping films of the invention exhibit a Gloss of more than 98,
more preferably more than 99 and most preferably more than 100 when
subjected to standard testing conditions referred to herein in the
Examples.
Examples
[0020] A 28 .mu.m film of regenerated cellulose was cast from
solution under standard conditions and in the presence of a
glycerol softener in an amount of approximately 12% by weight and
an amorphous silica antiblock in an amount of approximately 0.1% by
weight. Any other additives and components of the film were present
in standard quantities, and selected from the TVO list.
[0021] Five samples of the film, and a comparative sample
containing approximately 20% by weight softener (25% softener by
weight of cellulosic substrate) were subjected to physical testing
in accordance with BS2782-3, as amended by BS1133 to determine
Secant 1%, Tensile Strength, Elongation, Load and Youngs
Modulus.
[0022] The results are presented below in Table 1:

[0023] It will be seen that the films of Examples 1 to 5 exhibit
considerably less elongation than the comparative example, a
property which facilitates the compatibility of such films with
conventional industrial plant for the manufacture of cigarette
tipping films.
[0024] The films were further subjected to Coefficient of Friction
(COF) measurement in accordance with ASTMD1894. The results are
shown below in Table 2:

[0025] It will be seen that the films of Examples 1 to 5 exhibit
acceptable COF properties in relation to the comparative
example.
[0026] The films were further subjected to optical characterization
as follows:
[0027] Haze was measured in accordance with ASTMD 1003
[0028] Gloss was measured in accordance with ASTM D2457
