Ka kakaretso, lifilimi tse jeoang li na le tšebeliso e fokolang haholo-holo ka lebaka la litšobotsi tsa tsona tse tlaase tsa 'mele.Mohlala, lifilimi tse le 'ngoe, tse thehiloeng ho lipid li na le thepa e ntle ea thibelo ea mongobo empa ha li na matla a mochini23.Ka lebaka leo, lifilimi tsa laminated li ile tsa thehoa ka ho khomarela lifilimi tse peli kapa ho feta tsa biopolymer hammoho.Leha ho le joalo, lifilimi tsa laminated li molemo ho lifilimi tse le 'ngoe, tse thehiloeng ho emulsion ka lebaka la ho ba le thepa e ntlafetseng ea lithibelo.Ho bōptjoa ha mehaho ea laminated ho na le monyetla oa ho hlōla mefokolo ena ka boenjiniere ba lifilimi tse jeoang / tse nang le likokoana-hloko tse nang le likarolo tse ngata tse sebetsang.
