CPF Advanced

• Recent improved version of the well known CPF
  filters
• Features improved flute definition to improve the
  visual appearance
• The same handling benefits as the monoacetate
  filter so there is no need to adapt
  processes/equipment
• Can be used with flavours
• Offers a visually distinctive filter at a cost
  effective price
• Same level of superior performance as standard
  CPFTM, but with the added benefits of brand
  identity and possible anti-counterfeiting
  capability

Combined Performance Filter CPF Advanced

• Main benefit is the higher tar and nicotine
  retention when compared to monoaceate at the same
  filter PD
• Cellulose acetate fibre with embossed inner wrap
• Coloured inner wrap can increase the visual
  identity
• Configured with flutes to mouth (FTM) or flutes
  to tobacco (FTT)
• Suitable at all tar levels from full flavor to
  ultra low
• Design flexibility - combined as a dual, have
  flavor added or possible other options

Active Patch Filter

• Mono-process carbon filter.
• Patch of activated carbon is printed onto the
  inner surface of the plugwrap.
• Patch position is flexible, and Ventilation can
  be achieved through either single patch, or split
  patch configuration.
• Clean run filter concept - no machine
  contamination.
• Charcoal loading up to 3mg per linear patch mm.
• Total loading controlled by the length of the
  patch.
• Similar VP and SV performance to other charcoal
  filters with same charcoal loading, but with less
  "charcoal taste".

Special Carbons

• The performance of filters can also be enhanced
  by the use of higher activity carbons
• A recent version of these is a carbon that
  combines higher activity than standard coconut
  shell carbon with an impregnant that selectively
  removes Hydrogen Cyanide
• Such carbon is suitable for with all filter
  processes including the active patch.
• The removal of Hydrogen Cyanide is achieved more
  by a chemical action than physical adsorption
• The chemical removal of the Hydrogen Cyanide
  means that there is no change in reduction of
  Hydrogen Cyanide as cigarettes age

Conclusions

• The global trend for yield reduction of all
  compounds is expected to continue
• This can be achieved with monofilters
• Future developments are likely to include more
  effective monofilters and selective filtration
  agents
