Ngo-1951, kwasungulwa inkampani ebizwa ngokuthi iFlexigrip, Inc. ukuze ithuthukise futhi imakethe i-uziphu wepulasitikingegama elifanayo. Le ziphu yayisekelwe kusethi yamalungelo obunikazi, athengwa kumsunguli wawo, uBorge Madsen. Imikhiqizo yokuqala yeFlexigrip kanye neminyeiziphu zepulasitiki(njenge-iziphu ezingenasilayidi(toptite) ezathuthukiswa yiFlexigrip) kwakuyizinto zokufaka ezikhululekile kanye nezikhwama ezisicaba. Ngemva kwalokho, imizamo yokumaketha yaqondiswa ekupakisheni imikhiqizo e-izikhwama zepulasitiki eziziphu, okwaba yimakethe eyinhloko yemikhiqizo yeFlexigrip, Inc.. Ngo-1961, iFlexigrip, Inc. yathola enkampanini yaseJapan, iSeisan Nippon Sha, eyasungula uhlobo lweMinigripisikhwama sepulasitiki esinoziphu, amalungelo okukhiqiza nokuthengisa okukhethekile e-United States, ngokusekelwe ochungechungeni lweuziphu wepulasitikiAmalungelo obunikazi eSeisan. Kwasungulwa inkampani enegama elifanayo ukuze ikhiqize futhi imaketheIzikhwama ze-MinigripCishe ngo-1964, i-Minigrip, Inc. yaxoxisana ne-Dow Chemical Company ngelayisensi ekhethekile yokuhweba ngezitolo ezinkulu (izitolo ezinkulu). Kwaba yimpumelelo enkulu.
Ngaleso sikhathi,izikhwama zepulasitikizazikhiqizwa emazweni angu-25 ngesivinini somugqa esingamamitha angu-30 ngomzuzu, kodwa azikho ezazithengiswa kubathengi ngoba zazibiza kakhulu ukukhiqiza. I-Dow yabela omunye wabasunguli bayo, u-R. Douglas Behr, ukuthi athuthukise inqubo esheshayo nephumelelayo. Njengoba bengenalo ulwazi oluningi ngaphambili ku-ipulasitiki, lo msebenzi wawunzima kuBehr kodwa wadlula wonke umuntu emhlabeni kungakapheli nonyaka. Njengoba ethuthukisa inqubo futhi ekhulisa isivinini somugqa saya ku-60, sabe sesingu-90, sabe sesingu-150 futhi ekugcineni safinyelela kumamitha angu-300 ngomzuzu ngo-1972, kwadingeka aklame imishini emisha. Eminye yanikezwa ilungelo lobunikazi kanti eminye yagcinwa njengezimfihlo zokuhweba yiDow. Ekugcineni, abanye abacwaningi kanye nabasebenzi bokukhiqiza, njengochwepheshe belebhu uWilliam Shrum nabanye, bafaka isandla ekuthuthukisweni kwenqubo, kodwa uBehr waqhubeka nokuba ngumcwaningi oholayo kwaze kwaba yilapho ethatha umhlalaphansi ngo-1993 njengososayensi ohlangene ophezulu. Ngaleso sikhathi isakhiwo socwaningo "sasinikezelwe ekuqaphelisweni komsebenzi ovelele kaR. Douglas Behr".
Lokho'akungabazeki ukuthi. KusukelaNgo-1978, iMinigrip yathengwa yiSignode, Inc. futhi yaba yinkampani engaphansi kwaleyo nkampani. Ngo-1986, iSignode noDow bakha inkampani, iZippak, ukuze bathuthukise.izikhwama ze-zipperngemikhiqizo yokudla. Ngo-1987, i-ITW yathenga i-Signode, kwathi i-Minigrip yaba yinkampani engaphansi kwe-ITW. Ngo-1991, i-ITW yathola isithakazelo se-Dow ku-I-ZippakukuzeI-Zippakyaba yinkampani ephethwe ngokugcwele yi-ITW. I-Zippak ikhiqizaiziphu zepulasitikiOkweimakethe yokupakisha ukudlaKusukela ngesikhathi sokuqala kuze kube namuhla, i-Flexigrip/Minigrip/Zippak/Dow/Dow Brands ithole amalungelo obunikazi angaphezu kuka-300iziphu zepulasitiki, izikhwama ze-zipper, kanye nezindlela kanye nemishini yokukhiqiza okufanayo. Ngo-1997, iDow Chemical yathengisa amalungelo eDowBrands, afaka phakathi iZiploc, ku-SC Johnson ngemali ephakathi kuka-$1.3 no-$1.7 billion. I-Zip-Pak yathuthukisa ama-zipper ahambisana ne-Polypropylene ngo-2003.
Kodwa-kei-mongI-ZiplocfuthiI-Zippak'sAbancintisana nabo yiPresto, inkampani engaphansi kweReynolds, kanye nePactiv. Ngo-1995, uHefty, enye yezinkampani zikaReynolds, waphuma ne-slidingisikhwama se-zipper.
Imikhiqizo
I-Ziploc yandise imikhiqizo yayo yaba ngaphezu kwezikhwama zesangweji nje kuphela. Imikhiqizo ye-Ziploc manje iyahlukahluka kusukela ezikhwameni zefriji kuya ezitsheni ezisontekile. Inezikhwama ezingezansi ezinwebekayo ezizimele zodwa. Futhi inezikhwama ezinkulu. Lezi zikhwama zisetshenziselwa ukugcina ukudla okungekona ukudla futhi zinkulu njenge-2 ft by 2.7 ft (0.61 m × 0.82 m). Izikhwama ze-zip n' steam zisetshenziselwa ukupheka ukudla kuma-microwave. Ama-tote aguquguqukayo enziwe yiI-Ziploczisetshenziselwa ukugcina ukudla okungekona ukudla futhi zinkulu ngamalitha angu-22 e-US. Muva nje, i-Ziploc yenze umugqa othuthukisiwe wezikhwama zesangweji nezokugcina. Zonke izikhwama ezikulo mugqa zenziwe ngepulasitiki engaphansi ngo-25% futhi zenziwe kusetshenziswa amandla omoya. Isikhwama sesangweji se-Ziploc Evolve saphumelela kakhulu kangangokuthi sabhekwa njenge-"Best in Show" kuma-Best New Product Awards ka-2010 eCanada.
Ukukhangisa
I-SC Johnson and Son isebenzisa ukukhangisa kwezentengiselwano okubhaliwe, okuku-inthanethi, okusebenzisanayo, nokusakazwa kuthelevishini ngomkhiqizo wabo i-Ziploc. Lezi zikhangiso zisebenza eBrazil, eJalimane, eThailand, e-United States nakwamanye amazwe amaningi. Inhloko yokumaketha ye-Ziploc nguScott Heim ophatha imikhankaso yabo yezikhangiso yezigidi zamaRandi. Ngo-2002, i-SC Johnson & Son yethule umkhankaso wayo omkhulu kunayo yonke emlandweni, umkhankaso ongaphezu kwezigidi ezingama-50 zamaRandi wokwethula umugqa omusha wemikhiqizo yetafula/yokugcina elahlwayo ezothengiswa ngaphansi kwegama lomkhiqizo i-Ziploc. I-SC Johnson ivame ukugxila imikhankaso yayo ekuqondisweni kwezikhangiso zeThelevishini. Emkhankasweni ka-2002, amaRandi ayizigidi ezingama-35 anikelwe emkhankasweni weThelevishini. Ngo-2015, bakha umkhankaso wesikhangiso ne-Tough Mudder ukukhangisa omama ngendlela yokuvimbela.
Ukukhiqiza
Ukukhiqizwa kweIzikhwama ze-Ziplockuyahlukahluka phakathi kwemikhiqizo ehlukene. UmthethonquboI-Ziplocisikhwama sokugcina kanye nesikhwama sefriji senziwe ngeipulasitiki ye-polyethylene.
Umncintiswano
I-Ziploc ibhekene nokuncintisana okunamandla okuvela kubancintisani abanjengoGlad, Hefty, kanye nezinye izitolo eziningi eziphethwe ngasese, ezijwayelekile.izikhwama zepulasitikikanye nezitsha. Njengoba uJules Rose, usihlalo weSloan's Supermarkets Inc. eNew York City, esho: “Lena imakethe encintisana kakhulu enabadlali abaningi kanye nokuthengiswa kwamalebula azimele okunamandla ngendlela engavamile.” Ngo-1992, iZiploc yabhekana nokuncintisana okungazelelwe okuvela ekuthengisweni okukhulayo kwesikhwama se-Glad-Lock seFirst Brands Corporation esiphikisana nayo. Izikhwama ze-Glad Lock zenyuke ngo-13.1% emavikini ayi-12 ekupheleni kuka-1992, okwenza iGlad-Lock ibe nesabelo esingu-18.4% semakethe uma kuqhathaniswa nesabelo se-Ziploc esingu-43%.
