Abstract
A cigarette filter tipping film for encasing a filtration material comprises a biodegradable substrate and softener in an amount of less than 25% by weight of the biodegradable substrate. The biodegradable substrate may be selected from cellulosic substrates, PLA, starch based polymers and hydroxyalkanoates. The softener may be selected from glycerol, propane-1,2-diol and any other softener selected from the German Tobacco Ordnance (TVO) list. The film may be partially transparent. It may also contain less than 0.5% antiblock/winding aid additive such as amorphous silica, polyethylene glycol or antiblock/winding aids mentioned in the TVO list. The film may exhibit an elongation in the machine direction (MD) of less than 15%, a tensile strength (MD) of more than 140MPa, a Youngâs modulus (MD) of more than 4000MPa, a shrinkage under tropical conditions (MD) and/or transverse direction of less than 5%, a haze of less than 2.15 and a gloss of more than 98. .
Description
CIGARETTE FILTER
The present invention 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.
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.
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 elongatEon, 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.
The present invention seeks to address these issues.
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.
The biodegradable substrate is selected from biodegradable substrates, PLA substrates, starch based polymers, hydroxyalkanoates and other biopolymers, but is preferably a cellulosic substrate.
The invention also provides a cigarette filter comprising a filtration material encased in a cylinder of aforesaid tipping film.
Preferably the tipping film is at least mostly transparent so that the filtration material can be viewed through the tipping film.
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.
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 repfoduced as appendix 1 hereto, and combinations of two or more thereof.
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 tinning film. In order to of the invention exhibit a tensile strength in the machine direction of more than 14OMPa, more preferably more than 15OMPa and most preferably more than 155MPa when subjected to standard testing conditions referred to herein in
the Examples.
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 4000MPa, more preferably more than 5000MPa and most preferably more than 5500MPa when subjected to standard testing conditions referred to herein in the Examples.
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 is 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.
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
A 28pm 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.
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, The results are presented below in Table 1:
