Parizvino, mapepa epurasitiki anochinjika kurongedza chikafu chakaoma uye chikafu chine mvura chinonyanya kushandiswa mukofi, nzungu uye zviyo, mucheche formula, chikafu chekudya, mabhisikiti, zviyo nemafuta zvigadzirwa kana zvigadzirwa zvemukaka. Iyo huru dhizaini ndeye 4 akaturikidzana eakaumbwa akawanda-echikamu chimiro, iyo inovharira zvinhu ndeye aluminium foil, aluminium yakavharwa PET uye PVDC coating, oxygen chipingamupinyi uye mvura vapor barriers inogona kusvika padanho rakanaka, kusangana nezvinodiwa zveanopfuura gore rimwe rehupenyu hwesherufu, mukufambisa uye pasherufu hupenyu hunogona kuchengetedza kutsva kwechikafu. Asi iyo yezvakatipoteredza mhando yepepa-plastiki inosanganiswa haigone kuburitsa kukosha kwekudzokorora.
Sezvo zvinhu zvinochinjika zvakaumbwa zvekurongedza zvisingakwanisi kurongwa kuita mapepa nemapurasitiki muzvivakwa zvekudzokorodza, nyika huru dzakasimukira dzinosimudzira yakaderera kabhoni uye yakarongwa patsva inodzikamisa pachena huwandu hwemapepa uye epurasitiki anoumbwa epakeji anoshandiswa, kuderedza kudzvanywa kweanoumbwa zvinhu kudzokorodza uye huwandu hwese hwepepa uye pulp reprocessing.
Zvivako zvekurongedza zvine mapepa epamusoro zvinogona kudzokororwa, kudzoreredzwa kana kuumbwa, asi hazvipe zvakakwana kudzivirira kwechikafu kudzivirira oxidation yezviri mukati kana kudonha hunyoro munzvimbo dzinopisa uye dzine hunyoro. Kuchengeta kutsva uye kuchengetedzwa kwechigadzirwa panguva yekutumira, hupenyu hwesherufu uye kushandiswa kwemba kunonetsa.
Flexible food packaging barrier material, coating kana co-extrusion film structure, panguva imwe chete mukufambisa, sherufu yehupenyu uye nguva yekushandiswa kwevatengi ine yakagadzika chipingamupinyi okisijeni uye mhute yemvura kuita, kuitira kuchengetedza kutsva kwechikafu.
