Iinketho zesithintelo
Zonke iinketho zesithintelo ziyafumaneka, nto leyo eyenza ukuba ibe lukhetho oluguquguqukayo kakhulu kwiimfuno zakho.
Ukunyamezela ubushushu
Iipowutshi zokuma zingasetyenziselwa ukuzaliswa okushushu kunye neemveliso ezifakwe kwi-microwave ezifana neesuphu, iisosi okanye izidlo.
Kulula ukuthwala
Umthamo wezothutho wamawaka ambalwa eepoutshi ngekhathoni unciphisa kakhulu iimfuno zothutho, nto leyo ethoba iindleko zakho kunye nekhabhoni yakho.
Nciphisa inkcitho yokutya
Ukukwazi ukwahlula ulawulo ngokukhetha ubungakanani besingxobo kukhokelela ekuncitshisweni kwenkunkuma yokutya iyonke.
Izingxobo zokuma zibubunzima obulula kwaye buhlala ixesha elide endaweni yeetoti kunye neengqayi zeglasi, zibonelela ngesisombululo esiguqukayo sokupakishwa kwezicelo ezininzi.Oku kupakishwa okuguquguqukayo kunika izibonelelo ezininzi, ukuvumela ukubonakala kwemveliso, impilo engcono kunye nokhuseleko ekuphatheni, ukunciphisa iindleko zokuthutha kunye nokugcinwa kunye nokuphucula iindleko zomgca wemveliso.
Gcwalisa ngeesuphu, iisosi, iimveliso ezomileyo, iimveliso ezimanzi, iimveliso zenyama okanye iintlobo ezininzi zokutya.Siza kusebenzisana nawe ukwenza isingxobo sokuma silungele iimfuno zakho ezizodwa.
"Kubonakala kunzima ukukholelwa ngoku, kodwa abantu babengazi ukuba bavule njani isikhwama," uSteven Ausnit, umqambi weZiploc yasekuqaleni, usandul 'ukuxelela abaphulaphuli kwiYunivesithi yaseMarquette.Wakhumbula ukuba ngaxesha lithile ekuqaleni kweminyaka yoo-1960, inkampani yakhe yacenga iiRekhodi zaseColumbia ukuba zizame umkhono weplastiki oneziphu phezulu kwii-albhamu."Kwintlanganiso yokugqibela, sonke sasilungele ukuhamba. Umfana wabiza umncedisi wakhe, wamnika ibhegi evaliweyo kwaye wathi, 'Vula.'Ndazicingela, Nkosazana, nceda wenze into elungileyo! Okukhona wayeyijonga, kokukhona intliziyo yam yayisiba buhlungu. Waze wakrazula uziphu kanye ebhegini.
UAusnit, owabaleka eRomania yamaKomanisi nentsapho yakhe ngowe-1947, wayezama ukusebenzisa iziphu zeplastiki ukususela ngowe-1951. Kungelo xesha apho yena, uyise (uMax) nomalume wakhe (Edgar) bathenga ilungelo lokufaka iziphu yeplastiki yokuqala, eyayiyilwe ngummi waseDenmark. umqambi ogama linguBorge Madsen, owayengenasicelo sithile engqondweni.Baye benza inkampani ebizwa ngokuba yiFlexigrip ukwenza iziphu, eyasebenzisa isilayidi seplastiki ukutywina imijelo emibini edibeneyo.Xa isilayida sibonakalise ixabiso elikhulu ukuvelisa, u-Ausnit, injineli yoomatshini, wenza into eyaziwa ngoku njengoziphu yocinezelo kunye netywina.
Kwi-1962, u-Ausnit wafunda ngenkampani yaseJapan ebizwa ngokuba yiSeisan Nihon Sha, eyayifumene indlela yokufaka i-zipper kwisikhwama ngokwayo, eya kunciphisa iindleko zokuvelisa ngesiqingatha.(I-Flexigrip yayiqhoboshela iiziphu zayo kwiingxowa ezinomshicileli wobushushu.) Emva kokugunyazisa amalungelo, abakwa-Ausnits baseka inkampani yesibini ebizwa ngokuba yiMinigrip;Ikhefu labo elikhulu lafika xa iDow Chemical icela ilayisensi yegrosari yevenkile, ekugqibeleni yazisa ingxowa yeZiploc kwimarike yovavanyo ngo-1968. Yayingeyompumelelo yangoko, kodwa ngo-1973, yayiyimfuneko kwaye inqulwa."Akukho siphelo sokusetyenziswa kwezo ngxowa zinkulu zeZiploc," uVogue uxelele abafundi ngoNovemba.“Ukususela ekubambeni imidlalo ukugcina ulutsha luxakekile kuhambo olude oluya ezintabeni, ukuya kwiindawo ezikhuselekileyo zokugcina izinto zokuthambisa, izinto zoncedo lokuqala kunye nokutya.Nokuba iwigi yakho iya konwaba ngakumbi kwiZiploc.
