Iingxowa zokupakisha ze-kraft ezisekelwe kwiphepha elipheleleyo le-pulp yamaplanga.Ngoko umbala wohlulwe ube yiphepha elimhlophe lekrafti kunye nokuprintwa komthubi kwiphepha le-kraft.

Ifilimu yePP ingasetyenziswa kwiphepha ukukhusela emanzini.Umaleko, ukuprinta kunye nokwenza ibhegi indibaniselwano.Iindlela zokuvula kunye nekhava ngasemva zohlulwe ngokutywinwa kobushushu, ukusonga amaphepha kunye nokuqukumbela.

Xa kuziwa kwisikhwama sokuqala sokuthenga iphepha le-kraft, lazalwa ngo-1908 eSt. Paul, eMinnesota, eU.SA.Omnye umnini wevenkile yasekuhlaleni, uWald Duvena, sele eqalisile ukukhangela iindlela zokuvumela abathengi ukuba bathenge ngaphezulu ngexesha elinye ukuze kunyuswe intengiso.UDuvina ukholelwa ukuba kufuneka ibe yibhegi eyenziwe kwangaphambili enexabiso eliphantsi kwaye kulula ukuyisebenzisa, kwaye inokuthwala ubuncinci malunga neepounds ezingama-75.

Emva kovavanyo oluphindaphindiweyo, wavala ukuthungwa kwesi sikhwama kwiphepha le-kraft ngenxa yokuba yenziwe kwi-conifers enemicu yomthi emide, kwaye yaphathwa ngesoda ye-caustic epholileyo kunye neekhemikhali ze-alkali sulfide ngexesha lokupheka, okwenza Amandla okuqala omthi we-fiber. ukonakala kancinci, ngoko ke iphepha lokugqibela elivelisiweyo lidityaniswe ngokuqinileyo nefiber, kwaye iphepha liqinile kwaye linokumelana noxinzelelo olukhulu kunye noxinzelelo ngaphandle kokuqhekeka.

Kwiminyaka emine kamva, isikhwama sokuqala sephepha se-kraft sokuthenga sazalwa.Umzantsi wayo unoxande kwaye unomthamo omkhulu kuneengxowa zephepha ze-V zemveli.Intambo inqumla emazantsi nasemacaleni ukunyusa umthamo wayo wokuthwala umthwalo, kwaye amarhintyela amabini enziwa kumntla wengxowa yephepha ukwenzela ukuphakanyiswa lula.UDuvena wathiya ibhegi yokuthenga ngegama lakhe kwaye wayinika ilungelo elilodwa lomenzi ngo-1915. Ngeli xesha, umthamo wentengiso yonyaka wezo ngxowa zokuthenga ungaphaya kwe-100 lezigidi.

IQela lokuPakisha iGuangdong Chuangxin liphambili kushishino lwezothutho kunye nokupakisha amashishini obuchwepheshe obuphezulu ngophando kunye nophuhliso, imveliso, intengiso .Kukho iimpawu zorhwebo ezifana neYinuo, zhonglan, Huanyuan, Tronson,Cirratrusrtkunye namalungelo awodwa omenzi wechiza angaphezu kwama-30.Ukususela ekusekweni kwayo ngo-2008, injongo yoshishino “kukwenza ihlabathi libe nobuhlobo ngakumbi ngokwendalo nokusingqongileyo” kwaye izibophelele ekubeni yinkokeli yehlabathi ekupakishelweni kokhuseleko lwendalo—awona mashishini aphezulu angama-500 ehlabathini.
