Lisebelisoa tse tsebahalang haholo tsa lifilimi tse phahameng ke tse latelang:
1. Lisebelisoa tsa PVDC (Polyvinylidene Chloride)
Polyvinylidene chloride (PVDC) resin, e atisang ho sebelisoa e le thepa e kopantsoeng kapa thepa ea monomer le filimi e kopantsoeng, ke thepa e sebelisoang ka ho fetisisa ea ho paka litšitiso tse phahameng.Tšebeliso ea filimi e koahetsoeng ea PVDC e kholo haholo.Filimi e entsoeng ka PVDC ke tšebeliso ea polypropylene (OPP), polyethylene terephthalate (PET) e le thepa ea motheo.Ka lebaka la mocheso o phahameng oa ho nolofatsa oa PVDC e hloekileng, ho qhibiliha ha PVDC ho haufi le mocheso oa eona oa ho bola, 'me ho senyeha ha polasetiki ka kakaretso ho futsanehile, ho futhumala ha mocheso ho thata ebile ho thata ho sebelisoa ka ho toba.Tšebeliso ea 'nete ea filimi ea PVDC hangata ke copolymer ea vinylidene chloride (VDC) le vinyl chloride (VC), hammoho le acrylic methylene (MA) copolymerization e entsoeng ka filimi e ntle haholo ea thibelo.
