Imbali yeekomityi zephepha ihamba ngezigaba ezine: iikomityi zephepha ezinobumba / ezikhonkothayo iikomityi zephepha zokuqala zaziyi-conic, zenziwe ngesandla, zidibene kunye, kulula ukwahlula, kwaye kufuneka zisetyenziswe ngokukhawuleza.Kamva, iikomityi ezisongayo zongezwa kwiindonga zecala ukuze kwandiswe amandla eendonga zecala kunye nokuqina kwendebe, kodwa kunzima ukuprinta iipateni kule miba yokusonga, kwaye umphumo awulungile kakhulu.I-Waxed Paper Cup ngo-1932, ikomityi yokuqala yephepha eline-wax yaphuma, indawo yayo egudileyo ingaprintwa kwiipatheni ezahlukeneyo ezigqwesileyo, ukuphucula umphumo wokunyusa.Ngakolunye uhlangothi, i-wax yokugqoka kwikomityi yephepha inokuphepha ukudibanisa ngokuthe ngqo phakathi kwesiselo kunye nempahla yephepha, kwaye inokukhusela i-adhesive kunye nokuphucula ukuqina kwendebe yephepha;kwelinye icala, iphinda inyuse ubukhulu bodonga olusecaleni, ukwenzela ukuba amandla ekomityi yephepha aphuculwe kakhulu, ngoko ke, ukusetyenziswa kwephepha eliyimfuneko ekuveliseni iikomityi zephepha ezomeleleyo kuyancitshiswa, kwaye ixabiso lemveliso liyancitshiswa.Njengoko iikomityi zephepha ezenziwe ngewax zisiba zizikhongozeli zeziselo ezibandayo, abantu bakwanethemba lokusebenzisa isikhongozeli esifanelekileyo kwiziselo ezishushu.Nangona kunjalo, iziselo ezishushu ziya kunyibilika i-wax kwindawo yangaphakathi yekomityi, umlomo onamathelayo uya kwahlulwa, ngoko ke ikomityi yephepha egcwele i-wax ayifanelekanga ukubamba iziselo ezishushu.
Udonga oluthe tye lwendebe ephindwe kabini, ukuze kwandiswe ububanzi besicelo, ngowe-1940, iNdebe yodonga oluphindwe kabini lwaziswa kwimarike.Ikomityi yephepha ayilungele ukuthwala kuphela, kodwa ingasetyenziselwa ukubamba iziselo ezishushu.Emva koko, abavelisi bezi komityi bagqunywe ngelatex ukugquma izinto zephepha nge "Cardboard smell" kwaye bomeleze ukuvuza kwekomityi yephepha.Iikomityi zewax ezinomgangatho omnye ezigqunywe ngelatex zisetyenziswa kakhulu koomatshini bokuthengisa ukubamba ikofu eshushu.Iikomityi zephepha ezigqunywe, ezinye iinkampani zokutya zaqala ukwenza i-polyethylene efakwe kwikhadibhodi ukwandisa umqobo kunye nokutywinwa kokupakishwa kwephepha.Ngenxa yokuba indawo yokunyibilika ye-polyethylene iphezulu kakhulu kune-wax, uhlobo olutsha lwekomityi yesiselo efakwe nge-polyethylene ingasetyenziselwa ukubamba iziselo ezishushu.Kwangaxeshanye, i-polyethylene yokwambathisa kune-wax yokuqala yokwaleka egudileyo, iphucula imbonakalo yeekomityi zephepha.Ukongeza, itekhnoloji yokucubungula kwayo kunokusetyenziswa kwendlela yokwaleka i-latex ingabizi kwaye ikhawuleza.
