Biohajoavat muovit, joita PLA ja PBAT edustavat, ovat alkaneet puhjeta, ja my\u00f6s PVA on vaivihkaa noussut perinteisten muovien vaihtoehtojen joukkoon ja kehitt\u00e4nyt erilaisia sovelluksia. Jos PVA-kalvoksi valmistetaan perinteisen muovikalvon korvaamiseksi, sit\u00e4 voidaan k\u00e4ytt\u00e4\u00e4 muovipusseissa, elintarvikepakkauksissa ja muilla aloilla.<\/p>\n

Puhdas PVA-kalvo kest\u00e4\u00e4 huonosti vett\u00e4, ja sen k\u00e4ytt\u00f6 k\u00e4yt\u00e4nn\u00f6n sovelluksissa on hyvin rajallista. Siksi sit\u00e4 on useimmissa tapauksissa muutettava ja valmistettava, kuten valmistamalla vesiliukoisia kalvomateriaaleja, joiden p\u00e4\u00e4raaka-aineet ovat PVA-hartsi ja hapetettu t\u00e4rkkelys. Viime vuosina on lanseerattu vesiliukoisia ymp\u00e4rist\u00f6nsuojelupussituotteita, joiden p\u00e4\u00e4raaka-aineet ovat PVA, glyseroli, t\u00e4rkkelys jne. ja jotka voidaan nopeasti liuottaa veteen 70 \u00b0C:ssa, ja hajoamisnopeus voi saavuttaa yli 90% kompostointiymp\u00e4rist\u00f6ss\u00e4 180 p\u00e4iv\u00e4n kuluessa.<\/p>\n
