Ukunikezelwa kwenani leenketho ezikhoyo, ukukhetha isikhwama seplastiki esifanelekileyo kunokuba ngumsebenzi onzima.Oku kungenxa yokuba iingxowa zeplastiki zenziwe ngezinto ezahlukeneyo kwaye nganye yezi zinto inika abasebenzisi iimpawu ezithile.Zikwafumaneka kwiimilo ezahlukeneyo ezixubeneyo kunye nemibala.
Kukho iinguqulelo ezininzi zeengxowa zeplastiki ngaphandle, nangona kunjalo, ngokuziqhelanisa nohlobo ngalunye, ngokuqinisekileyo unokunciphisa ukhetho lwakho kakhulu kwaye ukhethe isikhwama esifanelekileyo kwiimfuno zakho.Ke, masingene ngaphakathi kwaye sijonge kwiindidi ezahlukeneyo zeengxowa zeplastiki ezikhoyo kwimarike namhlanje:
Uxinaniso oluPhezulu lwePolyethylene (HDPE)
Enye yeeplastiki eziqhelekileyo ezisetyenziswa kwihlabathi jikelele, i-HDPE ibonakalisa iimpawu ezahlukeneyo, nto leyo eyenza ukuba ibe yinto ebalaseleyo yokwenza iingxowa zeplastiki.Ikhaphukhaphu, ayifihli, ayinamanzi kunye nobushushu, kwaye inamandla aphezulu wokuzibamba.
Ngaphandle koko, iingxowa zeplastiki ze-HDPE zidibana ne-USDA kunye ne-FDA yezikhokelo zokuphatha ukutya, ngaloo ndlela zizenza zibe lukhetho oludumileyo lokugcina kunye nokuphakela ukutya ekukhupheni nasekuthengiseni.
Iingxowa zeplastiki zeHDPE zinokufumaneka kwiivenkile zokutyela, kwiivenkile ezithengisa ukutya, iivenkile zokutya, idelis kunye nasemakhaya ngeenjongo zokuzigcina nokupakisha.I-HDPE ikwasetyenziselwa iingxowa zenkunkuma, iibhegi eziluncedo, iibhegi zeT-shirt, kunye neengxowa zokuhlamba impahla, phakathi kwezinye.
IPolyethylene yoXinano oluPhantsi (LDPE)
Olu hlobo lweplastiki luqhele ukusetyenziselwa iibhegi eziluncedo, iibhegi zokutya, iibhegi zesonka kunye neebhegi ezinamandla aphakathi kunye neempawu ezolula.Nangona i-LDPE ingenamandla njengeengxowa ze-HDPE, ziyakwazi ukugcina izinto ezininzi, ngakumbi ukutya kunye neemveliso zenyama.
Ngaphezu koko, iplastiki ecacileyo yenza kube lula ukuchonga iziqulatho, ivumela i-restaurateurs ukuba ihlale kwindawo ekhawulezayo yeekhikhini zorhwebo.
Oko kuthethiweyo, iingxowa zeplastiki ze-LDPE ziguquguquka kakhulu kwaye zithandwa ukusetyenziswa ngokutywinwa kobushushu ngenxa yendawo ephantsi yokunyibilika.I-LDPE ikwadibana ne-USDA kunye ne-FDA yezikhokelo zokuphatha ukutya kwaye ikwasetyenziswa ngamanye amaxesha ukwenza ukusonga amaqamza.
I-Linear Low Density Polyethylene (LLDPE)
Owona mahluko mkhulu phakathi kweengxowa zeplastiki ze-LDPE kunye ne-LLDPE kukuba le yamva inegeyiji encinane kancinane.Nangona kunjalo, eyona nto ingcono ngale plastiki akukho mahluko kumandla, okuvumela abasebenzisi ukuba bagcine imali ngaphandle kokuthotyelwa kumgangatho.
Iingxowa ze-LLDPE zibonisa iqondo eliphakathi lokucaca kwaye zisetyenziselwa ukwenziwa kweengxowa zokutya, iingxowa zephephandaba, iingxowa zokuthenga kunye neengxowa zenkunkuma.Zingasetyenziselwa ukugcina ukutya kwiifriji kunye neefriji, ngenxa yokuba zisetyenziselwa ukugcinwa kwezinto zokutya ezininzi kwiikhitshi zorhwebo.
IPolyethylene yoXinano oluPhakathi (MDPE)
I-MDPE icace ngokuthelekiswa ne-HDPE, kodwa ayicacanga njenge-polyethylene ephantsi.Iingxowa ezenziwe nge-MDPE azihambelani nomgangatho ophezulu wamandla, kwaye kwaye azinwebeki kakuhle, ngoko ke azikhethwanga ukuthwala okanye ukugcinwa kweemveliso ezininzi.
Nangona kunjalo, i-MDPE yinto eqhelekileyo kwiingxowa zenkunkuma kwaye isetyenziswa ngokubanzi kwipakethe yabathengi kwiimveliso zephepha ezifana nephepha le-toiler okanye iitawuli zephepha.
Iipolypropylene (PP)
Iingxowa ze-PP zibonakaliswa ngamandla azo amangalisayo ekhemikhali kunye nokuchasana.Ngokungafaniyo nezinye iingxowa, iingxowa ze-polypropylene aziphefumli kwaye zilungele iimeko zokuthengisa ngenxa yobomi bazo obude.I-PP isetyenziselwa ukupakishwa kokutya, apho izinto ezifana neelekese, amantongomane, imifuno kunye nezinye i-confectionaries zingagcinwa lula kwiingxowa ezenziwe kuyo.
Ezi bhegi zicace ngakumbi kunezinye, zivumela abasebenzisi ukuba babonakale ngakumbi.Iingxowa ze-PP nazo zilungele ukutywinwa kobushushu ngenxa yendawo ephezulu yokunyibilika, kwaye, njengezinye iinketho zeengxowa zeplastiki, yi-USDA kunye ne-FDA evunyiweyo yokuphatha ukutya.
