Kugadzirwa uye kushandiswa kwekapu dzemapepa kunoenderana nemutemo wenyika wekuchengetedza nharaunda.Kutsiviwa kwemakapu epurasitiki anoraswa kunoderedza "kusvibiswa kwakachena".Iko kurerukirwa, hutsanana uye mutengo wakaderera wemapepa emakapu ndiwo kiyi yekutsiva mimwe midziyo kuti igare yakawanda pamusika.Makapu emapepa akakamurwa kuita zvinwiwa zvinotonhora uye zvinopisa zvekunwa zvinwiwa zvinoenderana nemashandisirwo azvo.Pamusoro pekuzadzisa zvidikanwi zvekurongedza kwavo uye mashandiro ekugadzirisa, zvinhu zvekapu zvemapepa zvinofanirwa kusangana nekuchinjika kwavo kwekudhinda.Pakati pezvinhu zvakawanda muhunyanzvi hwekudhinda, mamiriro ekupisa chisimbiso chemakapu emapepa anofanirawo kusangana.
Iyo yebepa kapu yemidziyo inogadzirwa nemuchina wekapu yemuchina inoumbwa nekudhinda kwakananga kwebepa remukombe webepa, kucheka kufa, kugadzira kugadzira, uye kumwaya wakisi yechikafu pamusoro.Maitiro ekugadzirwa kwekapu yekunwa inopisa ndeyekuti bepa remukombe webepa rakaputirwa mubepa remukombe webepa, rakadhindwa, kufa-cheka, uye kugadziriswa.Bepa rekutanga remakapu emapepa rinoumbwa nemashizha emiti.Maitiro ekugadzira anowanzo kushandisa mafiibhi echirimwa senge coniferous huni uye hardwood kuti apfuure nepapulp board mushure mekuputika.Iyo pepa kapu yemuchina wekapu yemuchina inoumbwa nebepa kapu base bepa uye epurasitiki resin zvimedu zvakasimudzwa uye zvakasanganiswa.Iyo resin yepurasitiki inowanzoshandisa polyethylene resin (PE).Bepa remukombe webepa rakaputirwa nekamwe-sided PE firimu kana kaviri-mativi PE firimu kuti rive rimwechete PE kapu bepa kana kaviri PE mapepa makapu.
PE yakavharwa bepa ine yayo isina-chepfu, isinganhuhwi, isingaravike;kuita kwehutsanana kwakavimbika;makemikari zvinhu zvakagadzikana;zvemuviri uye zvemagetsi zvimiro zvakaenzana, zvakanaka kutonhora kupikisa;kusamira kwemvura, kusamira kwemwando uye kumwe kupikisa okisijeni nemafuta;yakanakisa yekuumba zvivakwa uye yakanaka kupisa chisimbiso kuita.PE ine hombe yekugadzira vhoriyamu, yakanakira sosi uye yakaderera mutengo, asi haina kukodzera yekubika kupisa kwepamusoro.Kana iyo kapu yepepa ine zvakakosha kuita zvinodiwa, resin yepurasitiki ine mashandiro anoenderana inofanirwa kushandiswa pakuremedza
