1. Magwiridwe ndi kugwiritsa ntchito PVDC:
Makampani apulasitiki apadziko lonse lapansi amagwiritsidwa ntchito kugwiritsa ntchito kuchuluka kwamphamvu kwa thupi kuwonetsa kusiyana kwa magwiridwe antchito ndi zinthu zomwe zimakhala ndi mpweya wocheperako pansi pa 10 zimatchedwa.mkulu chotchinga zipangizo.10 ~ 100 amatchedwa zida zotchinga zapakati.Zoposa 100 zimatchedwa wamba chotchinga.Pakali pano, atatu anazindikiramkulu chotchinga zipangizopadziko lapansi ndi PVDC, EVOH ndi PAN.Zida zitatu zonse ndi copolymers.Chotchinga cha oxygen cha EVOH ndi chabwino kuposa cha PVDC ndipo cha PVDC ndi chabwino kuposa PAN;Pazotchinga mpweya wa madzi, EVOH ndi yabwino kuposa PVDC, ndipo PVDC ndiyabwino kuposa PAN.Komabe, pansi pa chinyezi chambiri, mawonekedwe a maselo a EVOH ali ndi - gulu la OH, lomwe ndilosavuta kuyamwa chinyezi, ndipo ntchito yake yotchinga idzachepetsedwa kwambiri.Nthawi yomweyo, zotchinga za zinthu za PAN zimachepanso kwambiri ndi kuchuluka kwa chinyezi cha chilengedwe.PVDC ndiye njira yabwino kwambiri yotchingazipangizo zamapulasitikimdziko lapansi.

Polyvinylidene chloride resin (PVDC) ndi copolymer yokhala ndi vinylidene chloride monomer monga chigawo chachikulu.Ndizinthu zopangira zinthu zabwino kwambiri zotchinga kwambiri, kulimba kolimba, kutsika kwamafuta kwambiri komanso kukhazikika kwamankhwala komanso kusindikiza kwabwino kwambiri komanso kusindikiza kutentha.Amagwiritsidwa ntchito kwambiri muzakudya, zamankhwala, zankhondo ndi zina.

Kupanga zinthu za PVDC zokhala ndi ukadaulo wapamwamba ndikofunikira kwambiri pakulinganiza zinthu za klorini m'makampani a chlor-alkali ndikuwongolera bwino mabizinesi komanso kupikisana.PVDC ili ndi katundu wotchinga wabwino kwambiri ngati cholembera.Kugwiritsa ntchito PVDC kuyika chakudya kumatha kukulitsa moyo wa alumali, ndipo nthawi yomweyo, kumateteza kwambiri mtundu, fungo ndi kukoma kwa chakudya.PVDC composite ma CD ali ndi zida zochepa zogwiritsira ntchito kuposa filimu wamba ya PE, mapepala, nkhuni,zitsulo za aluminiyumundi zinthu zina zopakira.Kuchuluka kwa zinyalala zonyamula katundu kwachepetsedwa kwambiri ndipo ndalama zonse zachepetsedwa, kuti akwaniritse cholinga chochepetsera ma phukusi.

PVDC imagwiritsidwa ntchito kwambiri m'mayiko akumadzulo, kuphatikizapo chakudya, mankhwala, zodzoladzola, mankhwala, hardware ndi makina opanga zinthu, ndipo amadziwika kuti "green" packaging materials.Kugwiritsiridwa ntchito kwa PVDC kumakhudzana ndi moyo wadziko lonse.Pakali pano, kumwa pachaka kwa PVDC kuli pafupifupi matani 50000 ku America & matani 45000 ku Ulaya, ndi matani pafupifupi 40000 ku Asia ndi Australia.Kukula kwapakati pachaka kwa msika wa PVDC ku Europe, America ndi Japan ndi 10%.Ku America, matani oposa 15000 a PVDC resin amagwiritsidwa ntchitovacuum phukusiza nyama zazikulu zatsopano chaka chilichonse, ndipo kumwa kwa PVDC zokutira pamapepala kumapanga 40% ya chiwopsezo chonse cha PVDC.Ku Japan ndi South Korea, zida zambiri zopangira ma PVDC zimagwiritsidwa ntchito muzakudya, mankhwala, mankhwala ndi zinthu zamagetsi zamagetsi.Kumwa kwapachaka kwa utomoni wa PVDC kumapitilira matani 10000 kokha pafilimu yapulasitiki.
