DSFH/JRW STRICTLY PRIVATE & COFFIDENTIAL. 9 th September, 1959. ZaBACCO AS A FILT-_-R_.H-EDIU1- FOR C I rAffEff-M. Extensive tests have been carried out to investigate the possibility of using finely cvt tobacco for the manufacture of filter rods for cigarettes. These tests have shown that the vse of such filters presents possibilities of importance. Some of the advantages and attributes of such a filter are:- W Great;L enhanced Tobacco Taste and jr7e . Lt:~.~r Eo7 pjY63T._ =.d~.ijg. A criticism of nornal filter material has always been that the smoke drawn through such a filter is insirid and tasteless. The -se of tobacco as a filter material gives the smoke considerably greater tobacco character than that which is ra-,sed through a normal filter. The nature of the tobacco used as a filter has a pronounced influence on the taste. This fact opens up a large field of possibilities: the high grade tcbacco used in the filter tip may iorrove the smolr_ing qualities of a lol! grale blend or disguise the unpleasant character of some local type of leaf. Alternatively, the use of Oriental leaf in the filter tip iri--arts a pronounced Oriental flavour to the smoke. It is thus possible that it may be found preferable in blended or American-tyl,e ci,arettes to usc a filter tip made of Oriental tn',7tcco and to ouit the usual pcrccnt;~Ee of Oriental leaf from the blend. A large number of combinations ray be tried, such as the use of an Oriental filter tip irith a Virginia flue-clired' cigarette, the use of a Virginia flue- cured tip with a blended cigarette, the use of a fer-mented blac', filter tip with a Virginia or blended cigarette or vice versa. arthermorc, experiments may be made flavourinr~ the tobacco used for the filter red '~)ut not necessarily that used -in the cigarette. This vould make it possi~!_e to experiment with flavours v!Uc1- have an unsuitable aroma when burnt but which might affect the smoke in a pleasing way when vsed on the tobocco in the tip.

Filter rods made according to these details may be made on most Cigarette Making Machines and filter tipped cigarettes, using these rods, tray be made up on any conventional filter tipping unit. In territories where ir.lport restrictions or lack of local manu- facturing facilities make the use of materials such as cellulose acetate or crimped paper difficult or expensive or impossible, this type of filter may be readily made.

This coripares favourably rith a cellulose acetate filter of 51100,000 denier of the same length -hen the leaf tobacco to be used in the filter is converted into rag at 200 cuts A-er inch. Finer cr-ts incrPase tl~e filtration efficiency but at the sa-me time also increase the drLq.,, resistance. For this reason it may be found that the optimum cuts to the inch are 200. For acceptable dra,.! resistance using this tobacco, it has been found that the filter rods should have a density of arproximately .39 9- rer cc. For instance, filter rods r.,easnring 90 mm. x 25.75 mm. ray be Trade at 15 to the ounce. The Paper used as a i-rra~per for the filter rods may be Crompton's Verge .2122. (d) :&ttractive Ap:)eELrance and Sales Value. The appearance of cigarettes made up with a tobacco filter is particularly attractive when the tobacco used i-n the filter is of a sharply contrasting shade to that used in the cigarette; for instance, the use of a bright Flue-cured tip on a blended cigarette. There would seen to be -:iuch sco-j7e in advertising such cigarettes; its enhanced and "full" tobacco taste, its effective but unobtrusive smoke filtration, the fact that its composition consists entirely of tobacco, are some of the points whic?l miglht be used. c0 co N.)
