Izinto zokuPakisha ukutya zichaziwe: Iintlobo, Ukusetyenziswa, kunye nomahluko ophambili

Iphepha, iplastiki, iPLA, ikrafti—phezu komhlaba, izinto zokupakisha ukutya ziyafana. Kodwa xa kusetyenziswa ngokwenene, ukukhetha ukhetho olungalunganga kudla ngokukhokelela ekuvutheni kwezikhongozeli, ukutya okumanzi, ukuhanjiswa okungaphumelelanga, okanye iimveliso ezingasindiyo ekuthuthweni.

Iimpawu zokutya ezininzi zivelisaizinto zokupakisha ukutyangokusekelwe kumkhwa, ixabiso, okanye inkangeleko, uze ufumanise kamva ukuba loo nto ayisebenzi phantsi kweemeko zokwenyani.

Kutheni enye iphakheji isebenza ngokugqibeleleyo kwisidlo esishushu, ngelixa enye ingaphumeleli ngexesha lokuhanjiswa?

Kutheni ukupakisha “okulungela indalo” ngamanye amaxesha kubiza kakhulu kodwa kusabangela izikhalazo zabathengi?

Inyani yile yokuba izinto zokupakisha ukutya ziziphatha ngendlela eyahlukileyo xa kushushu, kubanda, kufuma, naxa kuxinezelekile. Ngaphandle kokuqonda la mahluko, izigqibo zokupakisha ziba yinto yokuqikelela endaweni yokuba zibe yiqhinga.

1. Uhlu lwezixhobo zokuPakisha ukutya

Izinto zokupakisha ukutya zingahlulwahlulwa ngokubanzi ngokusekelwe kwizinto eziluhlaza, iimpawu zokusebenza, kunye nefuthe lokusingqongileyo.

1.1 Izixhobo zokuPakisha Ukutya eziSephepheni

Izinto ezisekelwe ephepheni zisetyenziswa kakhuluukupakishwa kwekomityi yephepha, kuqukaiikomityi zekofu zephephakwayeiikomityi zephepha ezilahlwayo zokutya neziselo, ingakumbi kwiziselo ezishushu, iziselo ezibandayo, kunye nokusetyenziswa kwento enye. Zivela kwimicu yomthi kwaye ziquka ikhadibhodi, ibhodi yekraft, kunye namaphepha agqunyiweyo. Ezi zinto zilula kwaye zibonelela ngokuprintwa okuhle kakhulu, okwenza ukuba zilungele iibhokisi ezisetyenziswa ekutyeni okomileyo okufana neenkozo, iibhisikithi, kunye nezinto ezibhakiweyo. Ukupakisha amaphepha kuvumela ukuphefumla, okunceda ukuthintela ukwakheka komswakama kwiimveliso ezithile. Nangona kunjalo, ngaphandle konyango, ifunxa ulwelo ngokulula, ngoko ke ukugqunywa kudla ngokongeza ukuze kuthintelwe amanzi ngcono. Kwiminyaka yakutshanje, ukusetyenziswa kwephepha eliphinda lisetyenziswe kuye kwanda kakhulu, kunceda ukugcina izixhobo kunye nokutsala abathengi abaqaphela indalo.

1.2 Ukupakisha Ukutya kwePhepha leKraft

Iphepha le-Kraft lenziwa kusetyenziswa inkqubo ye-sulfate, egcina imicu emide kwaye inika loo nto amandla aphezulu kunye nokumelana nokukrazuka. Ihlala inembonakalo yendalo emdaka ebonisa ubuhle obungenabungozi kwindalo, obuncinci.
Iphepha le-Kraft lisetyenziswa kakhulu kwi-iibhokisi zokutya zephepha, izikhongozeli zokutya ezithathwayokunyeiibhokisi zokupakisha ukutya ezilahlwayokwishishini leenkonzo zokutya. Amandla ayo kunye nokumelana kwayo nokukrazuka kwenza ukuba ifaneleke zombini kwiindawo zokutyela kunye nezokutya.
Xa igqunyiwe, iphepha le-kraft linika amandla okumelana negrisi, nto leyo eyenza ukuba lilungele ukutya okunamafutha njengenkukhu eqhotsiweyo, iiburger, kunye neepastries. Liyabola kwaye lingasetyenziswa kwakhona, nto leyo eyenza ukuba libe lolona khetho lukhethwayo kwiimpawu ezigxile ekuzinzeni.

1.3 Izixhobo zokuPakisha ukutya zePlastiki (iiPE kunye neendidi ezinxulumene noko)

I-Polyethylene (PE) yenye yezona plastiki zixhaphakileyo ekupakisheni ukutya, kuquka i-low-density PE (LDPE) kunye ne-high-density PE (HDPE). Iifilimu ze-PE ziguquguquka kwaye ziyamelana namaqondo obushushu aphantsi, zisetyenziswa kakhulu kwiingxowa zefriji, ii-cling wraps, kunye neebhotile. Zibonelela ngemiqobo emihle yokulwa nokufuma kunye neoksijini, zigcina ukutya kutsha ixesha elide ngexabiso eliphantsi. I-PE ifanelekile kwimveliso entsha, inyama, kunye neemveliso ezikhenkcezisiweyo. Ii-composites ze-PE ezinamalayelo amaninzi ziphucula ngakumbi amandla okugcina.

1.4 Izixhobo zokuPakisha ukutya ezibolayo (i-PLA kunye nezinye iindlela)

I-Polylactic acid (PLA) ifumaneka kwizixhobo ezivuselelekayo ezifana nesitatshi sombona, nto leyo eyenza ukuba ibe yindlela ephambili yeplastiki ebolayo. Inika ukucaca okuphezulu okufana neeplastiki zemveli kwaye isetyenziselwa iikomityi, iitreyi, kunye neefilimu. I-PLA inokonakala kwiindawo zokwenza umgquba kwimizi-mveliso, inciphise impembelelo yexesha elide kwindalo esingqongileyo. Ezinye iindlela ziquka i-PHA (polyhydroxyalkanoates) kunye nezinto ezisekwe kwisitatshi, ezifanelekileyo ekutyeni okungenaxesha elide.

Ukuze ukwazi ukuqonda ngcono la mahluko, kuluncedo ukuthelekisa iindidi ezithile zezinto ezibonakalayo ngokunzulu. Umzekelo, okuIsikhokelo sokupakisha ukutya kwephepha vs iplastikiihlukanisa ukusebenza kunye nokuthengisana okuzinzileyo phakathi kwephepha, i-PE, kunye nezinto ezixutyiweyo, ngelixa okuinqaku elinokuchumisa ngokuchasene nelibolayoinceda ekucaciseni ukuba zeziphi izibhengezo zokupakisha ezinobuhlobo nokusingqongileyo ezisebenza ngokwenene.

1.5 Ezinye Izinto Zokupakisha Ukutya Eziqhelekileyo

Ukongeza kwiindidi eziphambili, ezinye izixhobo zisetyenziselwa usetyenziso oluthile:
