Chikafu chekurongedza bhokisi, sezvinoreva zita rinoshandiswa kurongedza mabhokisi echikafu, rinogona kuverengerwa zvinoenderana nezvinhu zvakaita se: bhokisi remapuranga, bhokisi remapepa, bhokisi rejira, bhokisi redehwe, simbi bhokisi, marata ekurongedza bhokisi, nezvimwewo, zvinogona zvakare kuverengerwa zvinoenderana nezita rechigadzirwa senge: bhokisi rechipo, bhokisi rewaini, chokoreti bhokisi, peni bhokisi, nezvimwe zvakaiswa mubhokisi rekurongedza retii bhokisi rekutakura. huni, mapepa uye zvimwe zvinhu zvakasanganiswa pamwechete. Kurongedza bhokisi basa: chengetedza kuchengetedzwa kwechikafu mukufambisa, kuvandudza giredhi rezvigadzirwa, nezvimwe. Chinangwa chebhokisi rekurongedza chikafu chiri kunyanya kuchengetedza chikafu kubva mukufuridzirwa kwemakemikari emuviri uye hutachiona zvinhu, kuve nechokwadi chekuti kuumbwa kwekudya uye hunhu hwechikafu hahuchinji, kuitira kuchengetedza hutano hwevatengi. Uye zvakare, chikafu chakaputirwa chinopa akawanda ari nyore mamiriro ekufambisa, kuchengetedza, kutengesa uye kushandisa, uku uchisimudzira kutengesa. Kurongedzwa kwechikafu kurongedza kunogona kurebesa hupenyu hwayo hwekuchengetera uye hupenyu hwesherufu, uye kuderedza zvakanyanya tsika yekuora kwechikafu. Zvinhu zvinokanganisa kunaka kwechikafu ndeizvi: – chiedza; Yechipiri itembiricha; Chetatu iokisijeni; Ina hunyoro; Chechishanu, utachiona. Kubva pakugadzirwa kwechikafu, kutengesa uye kushandiswa kwematanho matatu ekuona, chinangwa chebhokisi rekurongedza chikafu: - ndechekudzivirira kuparara, kuve nechokwadi chemhando; Zviviri ndezvekudzivirira microbial uye guruva kusvibiswa; Chechitatu, ruramisa uye nekukasika kugadzirwa kwechikafu; Chechina, inobatsira pakufambisa uye kutenderera; Chechishanu, kuwedzera kukosha kwechikafu. Chikafu chekurongedza bhokisi zvinoenderana neyakagadzirwa zvinhu kuumbwa, yakakamurwa kuita polyethylene, polypropylene, polystyrene, polyvinyl chloride uye mamwe marudzi, polyethylene, polypropylene ipurasitiki yakachengeteka, inogona kushandiswa kuve nechikafu. Anoraswa furo epurasitiki mabhokisi zita rakazara inguva imwe-yakapetwa polystyrene snack bhokisi, iyo huru mbishi ndeye polystyrene uye furo agent, polystyrene is styrene polymers, inosvika pa65 madhigirii Celsius, kuchave nekumwe kusununguka kwe styrene uye kutama kwerudzi rwezvinhu zvinokuvadza zvinonzi dioxins, kukuvadza kumuviri wemunhu. Uye zvakare, inofuridza mumiriri zvakare imhando yemakemikari zvinhu zvinokuvadza kumuviri wemunhu. Mamwe mabhokisi echikafu echikafu anotyora mitemo yenyika yekudyara anoburitsa kunhuwa kusingafadzi kana akazadzwa nechikafu chinopisa, izvo zvinhu zvine chepfu zvinoburitswa nemabhokisi ezvikafu epurasitiki anopupuma. Izvi zvinhu zvinokonzeresa kukuvadzwa kweiyo yepakati tsinga yemunhu uye kutyisidzira zvakanyanya hutano hwevanhu.
