Ukuguquguquka kwePhepha eliQokelelweyo le-PE ekuPakisheni
Kwihlabathi lanamhlanje, ukupakisha kudlala indima ebalulekileyo ekugcineni umgangatho weemveliso nokuqinisekisa ukuthuthwa kwazo ngokukhuselekileyo. Enye yezinto zokupakisha eziye zathandwa kakhulu yile Iphepha eliGcotyiweyo le-PEKodwa yintoni kanye kanye iphepha eligqunywe nge-PE, kwaye kutheni lisetyenziswa kakhulu kumashishini ahlukeneyo?
Yintoni i Iphepha eliGcotyiweyo le-PE?
Iphepha eligqunywe nge-PE liphepha nje eligqunywe ngomaleko we-polyethylene (PE), uhlobo lweplastiki. I-Polyethylene isetyenziswa kakhulu ngenxa yeempawu zayo zokungabi namanzi nezomeleleyo, kwaye xa isetyenziswa ephepheni, iphucula amandla ephepha okumelana nokufuma, amafutha, kunye nezinye izinto ezingqongileyo. Le nkqubo ibandakanya ukufaka umaleko omncinci we-PE kwelinye okanye kumacala omabini ephepha, okwenza umphezulu ogudileyo, ongenakukwazi ukungena manzi. Oku kuyenza ibe yinto efanelekileyo yokupakisha, ngakumbi kwiimveliso ezifuna ukukhuselwa kulwelo okanye kwioyile.
Iipropati zePhepha eliQokelelweyo le-PE
Iingenelo eziphambili zephepha eligqunywe yi-PE ziquka:
Ukumelana Namanzi: Ingubo yepolyethylene yenza iphepha likwazi ukumelana namanzi kunye nolwelo, nto leyo enceda ekuthinteleni ukuba lingabi manzi okanye lonakale. Oku kuluncedo ngakumbi kwizicelo ezifana nokupakishwa kokutya, apho iphepha kufuneka lihlale linjalo nokuba lidibana nokufuma.
Ukumelana neGrisi: Ingubo ye-PE ikwasebenza njengesithintelo kwiioyile kunye negrisi. Oku kuluncedo ngakumbi kwizinto zokupakisha ukutya ezifana neebhokisi zepizza, iisandwich wrappers, okanye iibhegi zokutya okulula, ezidla ngokudibana nezinto ezinamafutha okanye ezinamafutha.
Ukuqina: Umaleko we-polyethylene wongeza amandla ephepha, okwenza lihlale ixesha elide kwaye lingakrazuki okanye liqhekeke. Oku kwenza iphepha eligqunywe nge-PE lifaneleke kwiimfuno zokupakisha ezinzima.
Umphezulu Onokuprintwa: Nangona kukho upende, iphepha eligqunywe nge-PE ligcina umphezulu oprintwayo, nto leyo eyenza ukuba lilungele ukuphawulwa kunye nokulebhelishwa ngokwezifiso. Nokuba ziilogo, ulwazi lwemveliso, okanye ezinye iindlela zoyilo, iphepha lingaprintwa ngee-inki ezikumgangatho ophezulu.
Ukusetyenziswa Okuqhelekileyo Kwephepha Eligqunywe Nge-PE
Iphepha eligqunywe nge-PE lisetyenziswa kakhulu kumashishini ahlukeneyo, ingakumbi ekupakisheni. Ezinye zezona zicelo zixhaphakileyo ziquka:
Izikhongozeli zokukhupha ukutya, ii-food wraps, ii-sandwich sleeves, kunye neekomityi zokusela zihlala zisebenzisa iphepha eligqunywe nge-PE ukukhusela ukutya kumswakama, amafutha, kunye nongcoliseko. Oku kuqinisekisa ukuba ukutya kuhlala kutsha kwaye ipakethe ihlala injalo.
Ngenxa yeempawu zayo zokukhusela, iphepha eligqunywe nge-PE likwasetyenziswa kwezinye iinkqubo zokupakisha zonyango ukukhusela iimveliso ekungcoleni okanye ekonakaleni.
Isiphelo esigudileyo nesikhazimlayo sephepha eligqunywe nge-PE lenza ukuba lilungele ukusonga izipho ezikumgangatho ophezulu ezimelana neenyembezi kunye nemibimbi ngelixa zinika ukukhanya okunomtsalane.
Izinto eziqwalaselwayo kwiNdalo
Nangona iphepha eligqunywe nge-PE linika iingenelo ezininzi ezisebenzayo, enye yeengxaki yimpembelelo yalo kwindalo esingqongileyo. Ugqunywe nge-polyethylene kwenza iphepha libe nzima ukuliphinda lisetyenziswe kunephepha eliqhelekileyo. Nangona kunjalo, kukho imizamo eqhubekayo yokuphuhlisa ugqunywe oluhlala ixesha elide okanye ukuphinda lisetyenziswe iphepha eligqunywe nge-PE ngeenkqubo ezikhethekileyo.
Abanye abavelisi bajika basebenzise i-polyethylene esekwe kwi-bio njengendlela enobuhlobo nokusingqongileyo. Ukongeza, amashishini amaninzi agxile ekunciphiseni inkunkuma kunye nokwandisa ukusebenziseka kwakhona kwezinto zabo zokupakisha, kuquka nephepha eligqunywe nge-PE.
Iphepha eligqunywe nge-PE liyinto eguquguqukayo eye yaba yinto ebalulekileyo kwishishini lokupakisha ngenxa yokufuma kwayo kunye nokumelana namafutha, ukuqina kwayo, kunye nomphezulu oprintwayo. Nokuba kukupakisha ukutya, izixhobo zonyango, okanye kwanezipho ezisongayo, iimpawu zalo ezikhethekileyo ziyenza ibe lukhetho oludumileyo kwiintlobo ngeentlobo zezicelo. Njengoko ulwazi ngokusingqongileyo lukhula, ubugcisa kwiingubo ze-PE ezizinzileyo bunokuphucula ngakumbi indima yezixhobo kwizisombululo zokupakisha ezinobuhlobo nokusingqongileyo.
