Ikepisi lepulasitiki le-pvc lewayini elibomvu lisho ibhodlela lepulasitiki elivala umlomo webhodlela. Ngokuvamile, iwayini elivalwe ngesivalo sikakhokho lizovalwa ngongqimba lwebhodlela lepulasitiki elivala emlonyeni webhodlela ngemva kokuba liboshiwe. Umsebenzi walolu ngqimba lwe-plastic bottle seal ikakhulukazi ukuvimbela ukhokho ukuthi ungakhunti futhi ugcine umlomo webhodlela uhlanzekile futhi uhlanzekile. Ngokuqondene nomsuka walolu ngqimba lwe-cap yenjoloba, kungatholakala ukuthi lwavela eminyakeni eyi-100 kuya kwengama-200 edlule.
Ezinsukwini zakuqala, abakhiqizi bewayini babengeza amakepisi phezulu ebhodleleni ukuvimbela amagundane ukuthi angakwazi ukuququda amakhokho futhi avimbele izikelemu ezifana ne-weevil ukuthi zingene ebhodleleni. Izigqoko zamabhodlela ngaleso sikhathi zazenziwe ngomthofu. Kamuva, abantu baqaphela ukuthi umthofu wawunobuthi, futhi umthofu owawusele emlonyeni webhodlela wawungena ewayinini lapho ulithela, okwakungafaka impilo yomuntu engozini. Ngo-1996, i-European Union kanye ne-United States ngesikhathi esisodwa bashaya umthetho wokuvala ukusetshenziswa kwamakepisi omthofu. Ngemuva kwalokho, ama-caps ngokuvamile enziwe ngezinto ze-tin, i-aluminium noma i-polyethylene.
Ukuvala ibhodlela lepulasitiki ubuchwepheshe bokuvala ukushisa, ngokuvamile okwenziwa ngokuzenzakalelayo ngomshini ngokushisisa ifilimu yepulasitiki nokusonga umlomo webhodlela.
Izici:
1. I-cap ye-raber ye-pvc ine-shrinkage enhle, futhi ingaboshelwa kahle entweni ehlanganisiwe ngemva kokunciphisa ukushisa, futhi akulula ukuwa.
2. Isigqoko serabha se-pvc asikwazi nje kuphela ukuvikela amanzi ngokuphumelelayo, umswakama-umswakama kanye nokuvikela uthuli, kodwa futhi nokuvikela kangcono umkhiqizo kusixhumanisi sokujikeleza.
3. Ilungele kakhulu ukupakishwa kwewayini neminye imikhiqizo ngomshini.
4. Iphethini yokuphrinta yekepisi yerabha ye-pvc yinhle kakhulu futhi icacile, futhi umthelela obonakalayo uqinile, olungele ukukhombisa izinga eliphezulu lomkhiqizo futhi uthuthukisa nakakhulu inani lomkhiqizo.
5. Izigqoko zepulasitiki ze-PVC zisetshenziswa kakhulu ekufakweni kwangaphandle kwamabhodlela ahlukahlukene ewayini elibomvu newayini, angakwazi ukuhlonza kangcono, ukukhangisa kanye nemikhiqizo emihle.
