Iingxowa zokupakisha zephepha le-kraft ezisekelwe kwiphepha le-pulp yomthi opheleleyo. Ngoko ke umbala wahlulwe waba liphepha le-kraft elimhlophe kunye nombhalo otyheli kwiphepha le-kraft.

Ifilimu ye-PP ingafakwa ephepheni ukuze ilikhusele emanzini. Ukudibanisa umaleko, ukuprinta kunye nokwenza iingxowa. Iindlela zokuvula kunye nezembozo zangasemva zahlulwe ngokuvala ubushushu, ukusonga iphepha kunye nokuquma.

Xa kufikwa kwingxowa yokuqala yokuthenga iphepha le-kraft, yazalwa ngo-1908 eSt. Paul, eMinnesota, e-USA. Omnye umnini-venkile yokutya yasekuhlaleni, uWald Duvena, uqalile ukukhangela iindlela zokuvumela abathengi ukuba bathenge okungakumbi ngexesha elinye ukuze bandise intengiso. UDuvina ukholelwa ukuba kufuneka ibe yingxowa eyenziwe kwangaphambili engabizi kakhulu kwaye kulula ukuyisebenzisa, kwaye inokuthwala ubuncinane malunga neekhilogram ezingama-75.

Emva kovavanyo oluphindaphindwayo, wavala ubume bale ngxowa kwiphepha le-kraft kuba yayenziwe ngee-conifers ezineefayibha zomthi ezinde, kwaye yanyangwa nge-caustic soda ethambileyo kunye neekhemikhali ze-alkali sulfide ngexesha lokupheka, okwenza ukuba amandla okuqala efayibha yomthi awonakali kangako, ngoko ke iphepha lokugqibela eliveliswayo liqhagamshelwe ngokuqinileyo nefayibha, kwaye iphepha liqinile kwaye linokumelana nokuxinana okukhulu kunye noxinzelelo ngaphandle kokuqhekeka.

Kwiminyaka emine kamva, kwazalwa ibhegi yokuqala yephepha le-kraft yokuthenga. Izantsi layo liyingxande kwaye linomthamo omkhulu kuneengxowa zephepha zemveli ze-V-bottom. Intambo idlula ezantsi nasemacaleni ayo ukuze yonyuse umthamo wayo wokuthwala umthwalo, kwaye kwenziwa iiluphu ezimbini zokutsala kwisiphelo esiphezulu sebhegi yephepha ukuze kube lula ukuyiphakamisa. UDuvena wayiqamba le bhegi ngegama lakhe waza wayinika ilungelo elilodwa lomenzi ngo-1915. Ngeli xesha, umthamo wonyaka wentengiso yeengxowa zokuthenga udlule kwi-100 yezigidi.

Iqela leGuangdong Chuangxin Packing liphambili kushishino lwezothutho kunye nokupakisha amashishini aphambili ngophando nophuhliso, imveliso, ukuthengisa. Kukho iimpawu zorhwebo ezifana neYinuo, zhonglan, Huanyuan, T.uRonson,Ci-rratrusrtkunye neepatenti zokuyila ezingaphezulu kwama-30. Ukusukela oko yasekwa ngo-2008, injongo yenkampani “kukwenza ihlabathi libe nobuhlobo ngakumbi nangaphakathi” kwaye izibophelele ekubeni yinkokeli yehlabathi ekupakisheni ukhuseleko lokusingqongileyo—amashishini angama-500 aphambili ehlabathini.
