Ukupakishwa kokutyalinyathelo elibalulekileyo lokuqinisekisa ukuba ukuthuthwa, ukuthengisa kunye nokusetyenziswa kwezinto zorhwebo akonakali ngenxa yeemeko zangaphandle zokusingqongileyo kunye nokuphucula ixabiso leemveliso.Ngokuphucuka okuqhubekayo komgangatho wobomi babahlali, ifuthe lezinto kubomi bemihla ngemihla babahlali liya lisanda, kwaye ingxaki yongcoliseko olumhlophe iya isiba mandundu ngakumbi.Izinto zepolymer eziguquguqukayo zeBiodegradable ziye zaba yindawo eshushu kuphando kunye nophuhliso lwezinto zokupakisha ukutya.Iimathiriyeli zepolymer ezibolayoayifuni indawo ekhethekileyo okanye uluhlu lweemeko zangaphandle ezifana nokukhanya, ubushushu kunye namanzi kwinkqubo yokuthotywa.Bafuna kuphela ukusebenzisa i-microorganisms ukuvelisa i-physicochemical reaction elungileyo kwaye ekugqibeleni bavelise i-carbon dioxide.Zonke iintlobo zezinto eziveliswa kukuwohloka komgangatho aziyi kuvelisa naluphi na ungcoliso kwaye zibeke isoyikiso esincinane kwimpilo yabantu.
I-Biodegradableizinto zepolymer azidingi indawo ekhethekileyo okanye uluhlu lweemeko zangaphandle ezifana nokukhanya, ukushisa kunye namanzi kwinkqubo yokuthotywa.Kufuneka basebenzise kuphelaii-microorganismsukuvelisa isenzo esihle se-physicochemical kwaye ekugqibeleni siveliseumoya omdaka.Zonke iintlobo zezinto eziveliswa kukuwohloka komgangatho aziyi kuvelisa naluphi na ungcoliso kwaye zibeke isoyikiso esincinane kwimpilo yabantu.
Iingxowa zokupakisha ezinokubola -iingxowa zekofukunye neengxowa zokupakisha ezinokuphinda zisetyenziswe-iingxowa zokupakisha ukutyauveliswe nguYantai Meifeng Plastic Packaging Co.
Kukho iintlobo ezintathu eziphambili zei-biodegradableizinto zepolymer.Enye zixhobo zepolymer eziveliswa yi-microorganisms, ezifumaneka ngokuyininzi ngokuvutshelwa kwe-microbial, kwaye ummeli omkhulu yi-polyhydroxybutyrate, eneempawu ezilungileyo ze-biodegradation.Nangona kunjalo, iindleko zokucubungula kunye nokuveliswa kwezinto ezinjalo ziphezulu kakhulu, kwaye azifane zisetyenziswe kwimveliso ethile.Okwesibini zizinto ezenziwe ngepolymer.Okwangoku, ezona zixhobo zisetyenziswa kakhulu kwimakethi yaseTshayina yipolyvinyl utywala kunye nepolycaprolactone.Phakathi kwabo, i-polycaprolactone isetyenziswa ngokubanzi kwipakethe yokutya.Okwesithathu zizinto zepolymer zendalo.Izinto eziqhelekileyo zepolymer zendalo ziquka i-cellulose, isitashi, iprotheni, kunye ne-chitosan njengezinto ze-matrix.Emva kokusetyenziswa kwexesha elithile, izinto zepolymer zendalo zinokuthotywa kakuhle kwaye azinampembelelo kwimeko yangaphandle yendalo.naluphi na ungcoliseko.
I-Biodegradableiipolymers yenye yezona zinto zintsha kakhulu kwindawo yokupakisha.Iipolymers zeBiodegradable zineenzuzo zeimithombo ebanzi, enokuphinda isetyenziswe, ukhuseleko lokusingqongileyo kwaye akukho ngcoliseko,kodwa i-biopolymers inemida ethile malunga nokumelana nobushushu, i-oksijini kunye neempawu zokuthintela umphunga wamanzi, iindleko kunye neempawu zomatshini.Ke ngoko, uphando lwale mathiriyeli yokupakisha kufuneka igxininiswe ngakumbi ukuphucula ubomi beshelufu, ixabiso lesondlo kunye nokhuseleko lwe-microbial yokutya.
Ngenxa yoko, iinkampani ezininzi ziye zaqalisa ukuphuhlisa ukupakishwa okwenziwe ngezinto ezinokubola, ukuhambelana nendlela yamaxesha kunye nokuziqhelanisa neemarike ezintsha.
