Bepa rechimbuzi, iro rinozivikanwawo sepepa rechimbuzi recrepe, rinonyanya kushandiswa pahutano hwevanhu hwezuva nezuva uye nderimwe remhando dzemapepa akakosha kuvanhu. Kuti bepa rechimbuzi ripfave, kupfava kwebepa rechimbuzi kunowedzerwa nekukwinya bepa nenzira dzemichina. Kune zvinhu zvakawanda zvekugadzira bepa rechimbuzi, zvinowanzoshandiswa zvinosanganisira donje, huni, huni, tsvina, pepa remarara nezvimwewo. Hapana saizi inodiwa pabepa rechimbuzi. Kana bepa rechimbuzi rine mavara rakagadzirwa, dhayi rakagadzirwa rinofanira kuwedzerwa. Bepa rechimbuzi rinoratidzwa nekunwa mvura kwakasimba, huwandu hwebhakitiriya hushoma (huwandu hwemabhakitiriya pagiramu yehuremu hwebepa hahufanirwe kudarika 200-400, uye mabhakitiriya anokonzera hutachiona akadai semabhakitiriya ecoliform haatenderwe), bepa racho rakapfava, rakakora zvakaenzana, harina maburi, uye rakakombama zvakaenzana, Ruvara rwakafanana uye tsvina shoma. Kana richigadzira mipumburu midiki yebepa rechimbuzi rine mativi maviri, nzvimbo yekuboora inofanira kunge yakafanana, uye maburi anofanira kunge akajeka, ari nyore kutyoka uye akatsvinda.
Pepa repasi rakarukwa nekongiri ndiro bepa repasi rakarukwa nekongiri, iro rinonyanya kushandiswa pakati pekadhibhodhi rakarukwa nekongiri. Mazhinji epepa repasi rakarukwa nekongiri rakagadzirwa nemupunga wakagadzirwa nelime negorosi, uye huwandu hunoshandiswa zvakanyanya ndehwe160 g/m2, 180 g/m2, uye 200 g/m2. Zvinodiwa zvepepa repasi rakarukwa chimiro chefiber chakafanana, ukobvu hwakaenzana hwemapepa epepa, uye mamwe masimba akadai sekumanikidzwa kweringi, simba rekudhonza, uye kuramba kupeta. Harityoki kana richidzvanywa, uye rinodzivirira kumanikidzwa kwakanyanya. Uye rine kuomarara kwakanaka uye kufema kwakanaka. Ruvara rwepepa ndereyero yakajeka, rakatsetseka, uye hunyoro hwakakodzera.
