Imarike yeeFilimu eziBanda kakhulu: I-EVOH ilawula iCandelo lokuPakisha ukutya

Uhlalutyo lwamva nje lwemarike lubonisa ukuba i-EVOH (Utywala be-Ethylene Vinyliifilimu ziyaqhubeka nokuba yinxalenye yecandelo lokupakisha ukutya elinomqobo omkhulu, limalunga nama-50% emarike.ivolumu[^1]. Esi sabelo sibalulekileyo semarike sibangelwa ziimpawu zomqobo ophezulu we-EVOH ngokuchasene neoksijini, ukufuma, kunye nezinye izinto zangaphandle ezinokubeka emngciphekweni umgangatho kunye nokhuseleko lokutya. Ingxelo igxininisa ukuba iifilimu zomqobo ophezulu, ingakumbi ezo ziquka i-EVOH, zihlala ziphumelela ngaphezu kwezixhobo zokupakisha eziqhelekileyo ngokubhekiselele ekwandiseni ixesha lokugcinwa kunye nokukhuselwa kwemveliso.

Iingcali zoshishino ziphawula ukuba imfuno ekhulayo yexesha elide lokugcinwa kweemveliso zokutya, ingakumbi kwiimarike ezisakhulayo nakwiindawo zasezidolophini ezineekhonkco zokubonelela ezintsonkothileyo, ibe ngumqhubi ophambili wokwamkelwa kokupakisha izithintelo ze-EVOH. Iimpawu ezibalaseleyo zesithintelo seoksijini, kunye nokukwazi kwayo ukugcina imveliso itsha kwaye isemgangathweni, zenza ukuba ibe luncedo kakhulu kwiimveliso zokutya ezinobuthathaka ezifana nenyama, ubisi, kunye nokutya okulungele ukutyiwa.

Ngaphezu koko, abavelisi bagxila ngakumbi ekuphuhliseni i-thinner Ifilimu ye-Evohngaphandle kokubeka emngciphekweni iipropati zomqobo, ukuphendula kwiingcinezelo zeendleko kunye neenkxalabo zozinzo. Le ndlela ihambelana nentshukumo ebanzi yoshishino yokunciphisa izinto ngelixa igcina okanye iphucula iimpawu zokusebenza. Ingxelo ikwabonisa ukuba ubhubhane we-COVID-19 ukhawulezise ukwamkelwa kwezisombululo zokupakisha ezinomqobo ophezulu, njengoko abathengi kunye nabathengisi befuna ukupakisha okubonelela ngokhuseleko olungcono kunye nobomi obude beshelufu.
