Impapuro zikoreshwa muri sosiyete yacuagasanduku k'umugati,agasanduku ka pizzan'ibindiudusanduku two gupakira ibiryoikorwa nubuhanga bugezweho bwo gukora impapuro, butanga buri mushyitsi ibicuruzwa byiza
Ku ngoma ya Han yo mu Burengerazuba (206 mbere ya Yesu), Ubushinwa bwari bumaze gukora impapuro, naho mu mwaka wa mbere wa Yuanxing (105) mu ngoma ya Han y'iburasirazuba, Cai Lun yateje imbere impapuro.Akoresha igishishwa, umutwe wumutwe, igitambaro, urushundura nubundi bikoresho bibisi kugirango akore impapuro binyuze muburyo bwo gutereta, gukubita, gukaranga, guteka, nibindi, aribyo nkomoko yimpapuro zigezweho.Ubu bwoko bwimpapuro, ibikoresho bibisi biroroshye kubibona, bihendutse cyane, ubwiza nabwo bwarateye imbere, kandi buhoro buhoro bukoreshwa cyane.Kugira ngo twibuke ibyo Cai Lun yagezeho, ibisekuru byakurikiyeho byise iyi mpapuro “Impapuro za Cai Hou”.
Impapuro ni kristu yuburambe bwigihe kirekire nubwenge bwabakozi bakora mubushinwa.Impapuro ni urupapuro rumeze nkibikoresho bya fibre bikoreshwa mukwandika, gucapa, gushushanya cyangwa gupakira.Mubisanzwe, bikozwe muburyo bwo guhagarika amazi ya fibre yibihingwa byasunitswe, bigahuzwa kuri net, bikabanza kubura umwuma, hanyuma bigahagarikwa bikuma.Ubushinwa nicyo gihugu cya mbere ku isi cyahimbye impapuro.
Ikoranabuhanga ryubu riratera imbere byihuse, kandi uburyo bugezweho bwo gukora impapuro bwakoreshejwe imashini.
Groundwood Pulp ikoresha imbaraga zo gusya kugirango ibone fibre yimbaho, izwi kandi nka mashini ya mashini, ishobora kugabanywa mumashanyarazi rusange, imashini itunganijwe neza, imashini itanga imashini, nibindi.
Imiti ya chimique ikoresha uburyo bwa chimique kugirango itandukane fibre na lignin kugirango ibone fibre yimbaho, zishobora kugabanywa mo soda, sulfite pulp, na sulfate pulp.
Semichemical pulp (Semichemical Pulp) Uhujije uburyo bwo gukanika imashini na chimique, birashobora gukomeza kugabanywa mubice bitagira aho bibogamiye, imiti ya soda ikonje, imiti ya mashini, nibindi.
