Izindleko zokuphila bezilokhu zikhuphuka emhlabeni wonke futhi manje zithinta yonke indawo yokuphila kwabantu.
Kubantu abaningi, izindleko zokukhula zingase zisho ukuthi ikhofi ephumayo manje selibiza kakhulu kunangaphambili.Idatha evela e-Europe ibonisa ukuthi izindleko zekhofi elithathwayo zikhuphuke ngaphezu kwengxenye yesihlanu onyakeni ongaphambi kuka-Agasti 2022 ngokuqhathaniswa no-0.5% ezinyangeni eziyi-12 ezandulele.
Lokhu kungase kuholele ekutheni amakhasimende amaningi aphise ikhofi ekhaya esikhundleni sokuthi ayale ukuthi lihambe, okuyindlela eyaduma ngesikhathi sokuqubuka kwe-Covid-19.Kuyithuba elihle laba rosa abaningi ukuthi babuyekeze ukukhetha kwabo ikhofi abaya nalo ekhaya.
Ukuze ugweme ukuhlukanisa amakhasimende ngomkhiqizo olahlekelwa ubusha ngokushesha okukhulu, kufanele kukhethwe ukupakishwa kwekhofi okulungile.Abathosi bavamise ukuligcina ikhofi labo ezikhwameni zekhofi ezine-foil ukuze bagcine ikhwalithi kabhontshisi.
Izindleko kanye nomthelela wemvelo walolu khetho, nokho, kungayenza ifaneleke kakhulu kwabanye abathosiwe kunabanye.
Ukuvela kokupakishwa kwe-foil
Ucwecwe lwe-aluminium ngokwesiko lwenziwa ngokusakaza ama-slabs e-aluminium encibilikisiwe.
I-aluminium igoqwe kuyo yonke le nqubo kuze kube yilapho kufinyelelwa ubukhulu obudingekayo.Ingakhiqizwa njengemiqulu ye-foil ngayinye enobukhulu obusuka ku-4 kuya ku-150 micrometer.
Kuwo wonke ama-1900s, ukudla okuthengiswayo kanye neziphuzo kuye kwasetshenziswa ucwecwe lwe-aluminium.Ngokuphawulekayo, esinye sezicelo zayo zokuqala kwaba ukuthi inkampani yamaswidi yaseFrance i-Toblerone isonge amabha kashokoledi.
Ngaphezu kwalokho, isebenze njengesembozo sepani lommbila amakhasimende angalithenga futhi alishise ekhaya ukuze adale ama-popcorn e-“Jiffy Pop” amasha.Ukwengeza, ithole ukuduma ekupakishweni kwezidlo ze-TV ezihlukene.
Ucwecwe lwe-aluminium lusetshenziswa kakhulu ukwakha amaphakheji aqinile, aqinile, futhi aguquguqukayo namuhla.Namuhla, ama-foil avame ukusetshenziselwa ukuhlanganisa amaphakethe ekhofi eliphelele noma eliphansi.
Ngokuvamile, iguqulwa ibe ishidi lensimbi elincanyana kakhulu futhi linamathiselwe kungqimba lwangaphandle lokupakisha oluvame ukwenziwa ngepulasitiki, iphepha, noma i-bioplastics njenge-polylactic acid.
Isendlalelo sangaphandle sivumela ukwenziwa ngokwezifiso, njengokuphrinta okucacisiwe kwekhofi ngaphakathi, kuyilapho ungqimba lwangaphakathi lusebenza njengesithiyo.
Icwecwe le-aluminium lilula, liphephile ukusetshenziswa ekudleni, ngeke ligle kalula, futhi livikela ukukhanya nomswakama.
Kodwa kunemikhawulo eminingana lapho usebenzisa izikhwama zekhofi ezine-foil.Njengoba imbiwa, i-aluminium ibhekwa njengesisetshenziswa esilinganiselwe esizogcina siphelile, sikhulise izindleko zokusetshenziswa.
Ngaphezu kwalokho, uma igoqiwe noma ishwabene, i-aluminium foil ngezikhathi ezithile ingalahlekelwa ukuma kwayo noma ithole ama-puncture amancane.Lapho upakisha ikhofi ku-foil, i-valve yokukhipha umoya kufanele ifakwe esikhwameni ngoba i-foil ingavalela umoya.
Ukuze kugcinwe ukunambitheka kwekhofi eligazingiwe futhi kuvinjwe ukupakishwa ukuthi kungaqhumi, isikhutha esikhishwa njengezingcolisi zekhofi elosiwe kumelwe sivunyelwe ukuba siphume.
Ingabe izikhwama zekhofi zidinga ukulayishwa nge-foil?
Isidingo sokupakishwa okuguquguqukayo sizokhula kanye nenani labantu bomhlaba.
Ngenxa yokusetshenziswa nokufinyeleleka kwayo, ukupakishwa kwekhofi okuguquguqukayo nakho kulindeleke ukuthi kubonakale ukwanda kwesidingo.
Ukupakisha okuguquguqukayo nakho kuvumelana nemvelo kakhudlwana kunokukhetha okuqhudelanayo, ngesilinganiso sokupakisha ukuya komkhiqizo esingaphansi izikhathi ezi-5 kuya kweziyi-10.
Amathani angaphezu kwezigidi ezingu-20 wezinto zokupakisha angase agcinwe e-EU kuphela uma amafemu engeziwe ethuthela emaphaketheni avumelana nezimo.
Ngakho-ke, amarosa ahlinzeka ngokupakisha okuvumelana nemvelo kakhudlwana angase akhuthaze amakhasimende ukuba akhethe umkhiqizo wawo kunemikhiqizo eqhudelanayo.Kodwa-ke, uphenyo lwakamuva lweGreenpeace luthole ukuthi esikhundleni sokuthi zigaywe kabusha, izinto eziningi ziyashiswa noma ziyekwe.
Lokhu kusho ukuthi abathosi kufanele basebenzise ukupakisha okuzinzile ngangokunokwenzeka.Ngisho noma i-foil iyinto ewusizo yokugqoka izikhwama zekhofi, kunezithiyo ezinabashicileli abafuna ezinye izindlela.
Ama-roasters amaningi akhetha ukusebenzisa ungqimba lwangaphakathi lwe-PET eyenziwe ngensimbi nolwelwesi lwangaphandle olwenziwe nge-polyethylene (PE).Nokho, i-adhesive ivame ukusetshenziswa ukubopha lezi zingxenye, okwenza zingahlukaniseki.
Njengoba i-aluminium esetshenziswe kuleli fomu ayikwazi ukugaywa kabusha noma ukutholwa, ngokuvamile igcina ngokushiswa.
Ilayini ye-polylactic acid (PLA) ingase ibe ukukhetha okungcono kwemvelo.Le bioplastic ikhiqizwa ngezinto ezivuselelekayo njengommbila nommbila futhi ayinabo ubuthi.
Ukwengeza, i-PLA ingase ibole esimweni sokwenza umquba wezohwebo futhi inikeze umgoqo oqinile ngokumelene namazinga okushisa aphezulu, ukumanzi, kanye nomswakama.Ukuphila kwesikhwama sekhofi kunganyuswa kuze kufike unyaka lapho i-PLA isetshenziselwa umugqa wesikhwama.
ukugcina ukupakishwa kwekhofi okuhambisana nemvelo
Nakuba izikhwama zekhofi ezinomugqa we-foil zingaba nezinzuzo, abathosi banezinhlobonhlobo zezinye izinketho ezingasiza ukugcina ubusha.
Kunezinketho ezimbalwa ezitholakalayo ezihambisana nemvelo, inqobo nje uma abarosi bazisa amaklayenti abo ukuthi bangazilahla kanjani ngendlela efanele.Isibonelo, abarosa ikhofi abakhetha ukupakishwa okufakwe kulayini we-PLA kufanele bacebise amakhasimende ukuthi abeke isikhwama esingenalutho emgqonyeni wokugaya kabusha noma inombolo yomgqomo.
Abagazingi bangase bafune ukuzibuthela ngokwabo izikhwama zekhofi esezike zasetshenziswa uma izindawo zokugaywa kabusha komakhelwane zingakwazi ukuphatha lokhu kwaziswa.
Amakhasimende angathola ikhofi elishibhile kubagazingi ukuze abuyise iphakethe lekhofi elingenalutho.I-roaster ingase ithumele izikhwama ezisetshenzisiwe emuva kumkhiqizi ukuze ziphinde zisetshenziswe noma zilahlwe ngendlela ephephile.
Ukwengeza, ukwenza kanjalo kuzoqinisekisa ukuthi izinto zokupakisha zangaphandle nezinsiza zokupakisha, njengeziphu namavalvu okukhipha umoya, zihlukaniswa ngokufanele futhi zicutshungulwe.
Abathengi bekhofi banamuhla banezidingo ezithile, futhi ukupakishwa kufanele kuqhubeke futhi.Amakhasimende adinga indlela yokugcina ikhofi lawo elinomthelela omncane ongaba khona kwezemvelo, okumele ngabe abagazingi bakunikeze.
Kwa-CYANPAK, sinikezela ngokukhethwa kwezixazululo zokupakishwa kwekhofi ezigaywa kabusha ezingamaphesenti angu-100 ezikhiqizwe ezinsizeni ezivuselelekayo njengephepha le-Kraft, iphepha lerayisi, noma iphakheji ye-LDPE enezingqimba eziningi enomugqa we-PLA eco-friendly, konke okwehlisa imfucuza futhi kusekele umnotho oyindilinga.
Ngaphezu kwalokho, sinikeza abarosi bethu inkululeko ephelele yokudala ngokubavumela ukuthi bazenzele ezabo izikhwama zekhofi.
