Abantu baqhele ukusonga zonke iintlobo zokutya kwiplastiki.Xa izitya kufuneka zifudunyezwe, ziyesaba ukuchithwa kweoli.Baphinde basonge umaleko weplastiki kwaye bawafake kwi-microwave ukuze baphinde bafudumale.Ngokwenene, ukusongwa kweplastiki ngokuthe ngcembe kuye kwaba yinto eyimfuneko kubomi bemihla ngemihla babantu.Kodwa, uyazi, yintoni le nto ibhityileyo yeplastiki esongelayo?
Okwangoku, ininzi yefilimu yokutya ethengiswa kwiimarike, njengeengxowa zeplastiki ezisetyenziswa ngokuqhelekileyo, zenziwe nge-ethylene masterbatch.Ezinye izinto zeplastiki zokugoqa ziyi-polyethylene (ebizwa ngokuba yi-PE), engenazo iiplastiki kwaye ikhuselekile ngokufanelekileyo ukuyisebenzisa;ezinye izinto ziyi-polyvinyl chloride (ebizwa ngokuba yi-PVC), ehlala idibanisa i-stabilizers kunye ne-lubricants , ii-Antiliary processing agents kunye nezinye izinto eziluhlaza ziyingozi kumzimba womntu.

Indlela yokwahlula ifilimu yokutya kunye ne-PVC?
1. Kwiliso lenyama: Izinto ze-PE zinokungafihli kakuhle, kwaye umbala umhlophe, kwaye ukutya okugqunyiweyo kubonakala kufiphele;Izinto zePVC zineglosi elungileyo kwaye zibukeka zicacile kwaye ziselubala, ngenxa yeplasticizer, kukhanya kancinci ukukhanyisa tyheli.

2. Ngesandla: Isixhobo se-PE sithambile, kodwa sinokuqina okulambathayo, kwaye sinokuphuka emva kokuzolula;Izinto zePVC zinokuqina okuqinileyo, zinokolulwa kakhulu kwaye zolulwe ngaphandle kokwaphuka, kwaye kulula ukunamathela esandleni.

3. Ukutshisa ngomlilo: Emva kokuba ifilimu ye-PE ye-cling itshiswa ngomlilo, ilangatye liphuzi kwaye livutha ngokukhawuleza, kunye nephunga elivuthayo lekhandlela;ngelixa ilangatye lefilimu yokubambelela ye-PVC ivutha i-yellow-green, ngaphandle kweoli ethontsizayo, iya kucinywa ukuba ishiya umthombo womlilo, kwaye inamandla Iphunga elibukhali.

4. Ukuntywiliselwa kwamanzi: Ngenxa yokuba ukuxinana kwezi zimbini zihluke, ubuninzi befilimu ye-PE cling iphantsi kunamanzi, kwaye iya kudada emva kokuntywiliselwa emanzini;ngelixa ubuninzi befilimu yokutya ye-PVC iphezulu kunamanzi, kwaye iya kutshona xa intywiliselwa emanzini.

Abantu kufuneka bajonge ngononophelo imathiriyeli ekwileyibhile yemveliso xa kuthengwa isongelo seplastiki.Izinto ezihambelanayo zezinto ze-PE zicocekile, zikhuselekile kwaye azinatyhefu.Xa uthenga, yiya kwivenkile eqhelekileyo ukuthenga iimveliso ezivela kubavelisi abaqhelekileyo.Xa usebenzisa, nikela ingqalelo kwiqondo lokushisa ukuba ifilimu yokutya inokumelana nayo, kwaye uyifudumeze ngokuhambelana neqondo lokushisa eliphawulwe kwi-brand, ukuze uthintele ifilimu ye-cling ephantsi ukuba ithambile xa ishushu kwaye ibangela ingozi kwimpilo yabantu.
