Unyaka we-1911 wawusisiganeko esibalulekileyo kwimbali yokupakishwa kokutya kwehlabathi.Ngenxa yokuba lo nyaka yayingunyaka wokuqala we-aluminium foil kwintsimi yokupakisha ukutya, kwaye ngaloo ndlela yaqala uhambo lwayo oluzukileyo kwintsimi yokupakisha ukutya.Njengovulindlela kwiukupakishwa kwefoyile ye-aluminium, Inkampani yetshokolethi yaseSwitzerland ikhule ngaphezu kweminyaka eyi-100 kwaye ngoku ibe yinto eyaziwayo (i-Toblerone).
Ifoyile yeAluminiyamngokuqhelekileyo ibhekisela kwi-aluminiyam enobunyulu obungaphezulu kwe-99.5% kunye nobukhulu obungaphantsi kwe-0.2 millimeters, ngelixa i-aluminium foil esetyenziselwa izinto ezidibeneyo inobunzima obuncinci.Ewe kunjalo, amazwe ahlukeneyo aneemfuno ezahlukeneyo zobunzima kunye nokwakheka kwefoyile ye-aluminium.Umbuzo ngulo, ngaba ifoyile yealuminiyam, ebhityileyo njengamaphiko ecicada, ingaba nako ukwenza umsebenzi obalulekileyo wokupakishwa kokutya?Oku kukwaqala ngomsebenzi wokupakishwa kokutya kunye neempawu zefoyile ye-aluminium.Nangona ukupakishwa kokutya ngokuqhelekileyo kungatyiwa, yinxalenye ebalulekileyo yeempawu zemveliso yokutya.Ngokumalunga nomsebenzi wokupakishwa kokutya, eyona nto ingundoqo ngumsebenzi wokukhusela ukutya.Ukutya kungena kwinkqubo entsonkothileyo ukusuka kwimveliso ukuya ekutyeni, enokuthi iphenjelelwe zizinto zangaphandle ezifana nebhayoloji, ikhemistri, kunye nefiziksi kwindalo esingqongileyo.Ukupakishwa kokutya kufuneka kukwazi ukugcina ukuzinza komgangatho wokutya kunye nokuchasana nemiphumo emibi eyahlukeneyo kwindalo.Kwangaxeshanye, ukupakishwa kokutya kufuneka kuhlangabezane neemfuno zobuhle, ukulunga, ukukhuselwa kwendalo kunye nokufikeleleka.
Makhe sijonge kwiimpawu zeifoyile yealuminiyamkwakhona.Okokuqala, ifoyile ye-aluminiyam inamandla amakhulu omatshini kunye nempembelelo ethile kunye nokuchasana nokubhoboza.Ngoko ke, ngexesha lokugcina, ukuthutha, kunye nezinye iinkqubo,ifoyile aluminiyam epakishwe ukutyaayonakaliswa lula ngenxa yezinto ezifana noxinzelelo, impembelelo, ukungcangcazela, ukuhluka kobushushu, njl. Okwesibini, ifoyile ye-aluminium inomsebenzi omthintelo ophezulu, ochasene kakhulu nokukhanya kwelanga, ubushushu obuphezulu, ukufuma, ioksijini, iintsholongwane, njl. zonke izinto ezikhuthaza ukonakaliswa kokutya, kunye nokuthintela ezi zinto kunokwandisa ubomi beshelufu yokutya.Okwesithathu, i-aluminium foil kulula ukuyiqhuba kwaye inexabiso eliphantsi, elinokuthi lihlangabezane neemfuno zokupakisha ukutya okuninzi kwaye inombala omhlophe wesilivere kunye nokuthungwa okungaqondakaliyo.Okwesine, i-aluminiyam yentsimbi ngokwayo iyintsimbi ekhaphukhaphu, kwaye icwecwe elibhityileyo kakhulu le-aluminiyam lihlangabezana neemfuno ezisisiseko zokupakishwa okukhaphukhaphu, okubaluleke kakhulu ekunciphiseni iindleko zokuhamba.Okwesihlanu, i-aluminium foil ayinayo ityhefu kwaye ayinavumba, kulula ukuyibuyisela kwakhona, kwaye ihlangabezana neemfuno zokukhusela okusingqongileyo kunye nophuhliso oluzinzileyo.
Nangona kunjalo, kwindlela yokupakisha ukutya,ifoyile yealuminiyamkunqabile ukuba isetyenziswe iyodwa, kuba ifoyile yealuminiyam nayo inazo iintsilelo.Ngokomzekelo, njengoko i-aluminium foil iyancipha ngakumbi, inani le-pores liya kwanda, eliya kuchaphazela ukusebenza komqobo we-aluminium foil.Okwangoku, i-foil ye-aluminium ekhaphukhaphu kunye nethambileyo inemida ngokwemiqathango yokuqina kunye nokumelana nokucheba, kwaye ihlala ingafanelekanga ukupakishwa kwesakhiwo.Ngethamsanqa, ifoyile yealuminiyam inomsebenzi oncomekayo wokuqhubekeka wesibini.Ngokuqhelekileyo, izinto zokupakisha ezidibeneyo zingenziwa ngokudibanisa i-aluminium foil kunye nezinye izinto zokupakisha ukwenza ukusilela kwe-aluminium foil kunye nokuphucula ukusebenza okubanzi kokupakisha kwezinto zokupakisha ezidibeneyo.
Ngokuqhelekileyo sibhekisela kwifilimu eyenziwe ngezinto ezimbini okanye ngaphezulu njengefilimu edibeneyo, kunye nengxowa yokupakisha eyenziwe ngefilimu edibeneyo ibizwa ngokuba yi-composite film bag.Ngokubanzi, iplastiki,ifoyile yealuminiyam, iphepha kunye nezinye izinto zingenziwa kwiifilimu ezidibeneyo ngokudibanisa okanye ukutywinwa kokushisa ukuhlangabezana neemfuno zokupakisha ezahlukeneyo zokutya okuhlukahlukeneyo.Kwipakethe yanamhlanje, phantse zonke izinto ezidibeneyo ezifuna ukukhanya kunye nezithintelo eziphezulu zenziweifoyile aluminiyam njengomaleko wesithintelo, ngenxa yokuba i-aluminium foil inesakhiwo sekristale esishinyene kakhulu kwaye inomsebenzi omhle womqobo kuyo nayiphi na igesi.
Kwipakethe ethambileyo yokutya, kukho imathiriyeli yokupakisha ebizwa ngokuba yi "vacuum aluminized film".Ngaba iyafana nai-aluminium foil composite izinto zokupakisha?Nangona zombini ziqulethe umaleko obhityileyo kakhulu we-aluminiyam, aziyonto enye.Ifilimu yokucoca i-aluminiyam yeVacuum yindlela yokuphuphuma komphunga kunye nokufaka i-aluminiyam ecocekileyo ephezulu kwifilimu yeplastiki kwindawo yokucoca, ngelixa.Ifoyile ye-aluminiyam yezinto eziphathekayoyenziwe ngefoyile ye-aluminiyam kunye nezinye izinto ngokudibanisa okanye i-thermal bonding.
NgokungafaniyoIfoyile ye-aluminiyam izinto ezidibeneyo, Ukufakwa kwe-aluminium kwifilimu efakwe kwi-aluminium ayinayo impembelelo yomqobo ye-aluminium foil, kodwa kunoko ifilimu ye-substrate ngokwayo.Njengoko umaleko owenziwe ngealuminiyam uncinci kakhulu kunefoyile yealuminiyam, ixabiso lefilim yealuminiyamu lisezantsi kuneloIfoyile ye-aluminiyam yezinto eziphathekayo, kwaye imarike yesicelo sayo ibanzi kakhulu, kodwa ayisetyenziswa ngokubanzi ukupakisha iVacuum.
