Kana zvasvika pakuchengetedza waini, kusarudzwa kwebhodhoro liner kunoita basa rakakosha mukuchengetedza mhando yewaini. Zvinhu zviviri zvinowanzo shandiswa liner, Saranex naSarantin, imwe neimwe ine hunhu hwakasiyana hwakakodzera kune zvakasiyana chengetedzo zvinodiwa.
Saranex linersinogadzirwa kubva kune yakawanda-layer co-extruded firimu ine ethylene-vinyl doro (EVOH), ichipa mwero oxygen barriers zvivakwa. Iine mwero wekufambiswa kweokisijeni (OTR) yeanenge 1-3 cc/m²/24 maawa, Saranex inobvumira shoma shoma yeokisijeni kupinda mubhodhoro, iyo inogona kukurumidzira kuibva kwewaini. Izvi zvinoita kuti ive yakanaka kune waini dzakagadzirirwa kushandiswa kwenguva pfupi. Iyo mvura vapor transmission rate (WVTR) yeSaranex zvakare iri pakati nepakati, yakatenderedza 0.5-1.5 g/m²/24 maawa, iyo inokodzera waini inozonakidzwa mukati memwedzi mishoma.
Sarantin liners, kune rumwe rutivi, anogadzirwa kubva kune yakakwirira-chivharo PVC zvinhu zvine yakaderera permeability, ine OTR yakaderera se 0.2-0.5 cc/m²/24 maawa, zvinonyatso kunonoka maitiro eoxidation kuchengetedza waini yakaoma inonaka. Iyo WVTR zvakare yakadzikira, kazhinji kutenderera 0.1-0.3 g/m²/24 maawa, zvichiita kuti Sarantin yakanakira mawaini ekutanga anoitirwa kuchengetedza kwenguva refu. Tichifunga nezve yakakwirira chipingamupinyi zvivakwa, Sarantin inoshandiswa zvakanyanya kune waini inotarisirwa kukwegura kupfuura makore, kuve nechokwadi chekuti hunhu hunoramba husina kukanganiswa nekuratidzwa kweokisijeni.
Muchidimbu, Saranex inonyatsokodzera waini dzakagadzirirwa kunwa kwenguva pfupi, nepo Sarantin ndiyo yakanakira waini dzemhando yepamusoro dzakagadzirirwa kuchengetedza kwenguva refu. Nekusarudza jira rakakodzera, vagadziri vewaini vanogona kusangana zviri nani kuchengetedza uye kunwa zvinodiwa nevatengi vavo.
