Ngoku,izixhobo zokupakisha izinto zokuthambisa ezibolayoziye zasetyenziswa ekupakisheni iikhrimu, iilipstick kunye nezinye izinto zokuthambisa eziqinileyo. Ngenxa yobuchule bezinto zokuthambisa ngokwazo, akufuneki nje kuphela ukuba nenkangeleko eyahlukileyo, kodwa kufuneka nokuba nepakeji ehlangabezana nemisebenzi yayo ekhethekileyo.
Umzekelo, ukungazinzi okukhoyo kwezinto zokuhlobisa kufana nokutya. Ke ngoko, ukupakishwa kwezinto zokuhlobisa kufuneka kubonelele ngeempawu zokuthintela ezisebenzayo ngakumbi ngelixa kugcinwa iimpawu zobuhle. Kwelinye icala, kuyimfuneko ukwahlula ngokupheleleyo ukukhanya nomoya, ukuthintela ukubola kwemveliso, kunye nokwahlula iintsholongwane kunye nezinye iintsholongwane ukuba zingangeni kwimveliso. Kwelinye icala, kufuneka kuthintele izithako ezisebenzayo kwizithambiso ukuba zingafunxwa zizinto zokupakisha okanye zisabele nazo ngexesha lokugcina, nto leyo eya kuchaphazela ukhuseleko kunye nomgangatho wezithambiso.
Ukongeza, ukupakishwa kwezinto zokuhombisa kuneemfuneko eziphezulu zokhuseleko lwebhayoloji, kuba kwizongezo zokupakishwa kwezinto zokuhombisa, ezinye izinto eziyingozi zinokunyibilikiswa zizithambiso, nto leyo ebangela ukuba izinto zokuhombisa zingcoliswe.
Izixhobo zokupakisha izithambiso ezinokubola:
Izinto zePLAinokulungiswa kakuhle kwaye ihambelana kakuhle nezinto eziphilayo, kwaye okwangoku yeyona nto iphambili yokupakisha ebolayo kwizinto zokuthambisa. Izinto ze-PLA ziqinile kwaye ziyamelana noomatshini, nto leyo eyenza ukuba ibe yinto elungileyo yokupakisha izinto zokuthambisa eziqinileyo.
I-Cellulose kunye neziphumo zayozezona polysaccharides zisetyenziswa kakhulu ekuveliseni iipakeji kwaye zezona polymers zendalo zininzi emhlabeni. Ziqulathe iiyunithi ze-glucose monomer ezidityaniswe kunye zii-B-1,4 glycosidic bonds, ezivumela ii-cellulose chains ukuba zenze ii-hydrogen bonds eziqinileyo. Iipakeji ze-cellulose zifanelekile ukugcina izinto zokuthambisa ezomileyo ezingezizo ezi-hygroscopic.
Izinto zesitatshiziipolysaccharides ezenziwe yi-amylose kunye ne-amylopectin, ikakhulu ezifumaneka kwiinkozo, i-cassava kunye neetapile. Izinto ezisekwe kwisitatshi ezithengiswayo ziquka umxube wesitatshi kunye nezinye iipolymers, ezifana ne-polyvinyl alcohol okanye i-polycaprolactone. Ezi zinto ze-thermoplastic ezisekwe kwisitatshi zisetyenziswe kwiintlobo ngeentlobo zezicelo zoshishino kwaye zinokuhlangabezana neemeko zokusetyenziswa kwe-extrusion, i-injection molding, i-blow molding, i-film blowing kunye ne-foam ye-cosmetic packaging. Ifanelekile kwi-non-hygroscopic dry cosmetic packaging.
IChitosanInamandla okupakisha izinto ezibolayo ngenxa yomsebenzi wayo wokulwa neentsholongwane. I-Chitosan yi-cationic polysaccharide ephuma kwi-deacetylation ye-chitin, ephuma kwiigobolondo ze-crustacean okanye kwi-fungal hyphae. I-Chitosan ingasetyenziswa njengengubo kwiifilimu ze-PLA ukuvelisa ukupakisha okuguquguqukayo okubolayo kunye ne-antioxidant.
