Kuthekani ngembali yengxowa yokutshixa eneziphu?

Ngo-1951, inkampani ebizwa ngokuba yiFlexigrip, Inc. yasekwa ukuze iphuhlise kwaye ithengise i-iziphu yeplastikienegama elifanayo. Le ziphu yayisekelwe kwiseti yamalungelo omenzi, awathengwa kumqambi wabo, uBorge Madsen. Iimveliso zokuqala zeFlexigrip kunye nezinyeiiziphu zeplastiki(njengeiiziphu ezingenasilayidi(toptite) ezaphuhliswa yiFlexigrip) yayizizinto zokubopha ezikhululekileyo kunye neebhegi zebriefcase ezisicaba. Emva koko, imizamo yokuthengisa yajoliswa ekupakisheni iimveliso kwiiingxowa zeplastiki eziziphu, eyathi yaba yimarike ephambili yeemveliso zeFlexigrip, Inc. Ngo-1961, iFlexigrip, Inc. yafumana kwinkampani yaseJapan, iSeisan Nippon Sha, eyasungula uhlobo lweMinigripibhegi yeplastiki ye-zipper, amalungelo okuvelisa nokuthengisa akhethekileyo e-United States, ngokusekelwe kuthotho lweiziphu yeplastikiIipatenti zeSeisan. Kwasekwa inkampani enegama elifanayo ukuze ivelise kwaye ithengiseIingxowa zeMinigripMalunga nowe-1964, iMinigrip, Inc. yathetha-thethana neDow Chemical Company ngelayisenisi ekhethekileyo yorhwebo lwevenkile yokutya (iivenkile ezinkulu) ukuze ifumane imveliso yeMinigrip. Yaphumelela kakhulu.

Ngela xesha,iingxowa zeplastikizaziveliswa kumazwe angama-25 ngesantya somgca seenyawo ezingama-30 ngomzuzu, kodwa akukho nanye eyayithengiswa kubathengi kuba yayibiza kakhulu ukuba ingaveliswa. UDow wabela omnye wabasunguli bayo, uR. Douglas Behr, ukuba aphuhlise inkqubo ekhawulezayo nesebenzayo. Ukuba namava amancinci ngaphambili kwiiiplastiki, lo msebenzi wawunzima kuBehr kodwa wadlula wonke umntu emhlabeni kungekapheli nonyaka. Njengoko wayephucula inkqubo kwaye enyusa isantya somgca ukuya kuma-60, emva koko ama-90, emva koko ama-150 kwaye ekugqibeleni ama-300 eenyawo ngomzuzu ngo-1972, kwafuneka ayile izixhobo ezintsha. Ezinye zanikwa amalungelo obunikazi kwaye ezinye zagcinwa njengemfihlo zorhwebo nguDow. Ekugqibeleni, abanye abasebenzi bophando kunye nemveliso, abafana netekhnoloji yelebhu uWilliam Shrum nabanye, banegalelo ekuphuhlisweni kwenkqubo, kodwa uBehr waqhubeka nokuba ngumphandi okhokelayo de wathatha umhlala-phantsi ngo-1993 njengososayensi oncedisayo ophezulu. Ngelo xesha isakhiwo sophando "sasinikezelwe ekuqaphelisweni komsebenzi obalaseleyo kaR. Douglas Behr".

Oko'Akukho mathandabuzo ngaloo nto. Ukususela ngokoNgowe-1978, iMinigrip yathengwa yiSignode, Inc. yaza yaba lisebe eliphantsi kwaloo nkampani. Ngowe-1986, iSignode kunye noDow baseka inkampani, ebizwa ngokuba yiZippak, ukuze baphuhlise.iingxowa ze-zipperkwiimveliso zokutya. Ngo-1987, i-ITW yathenga iSignode, kwaye iMinigrip yaba lisebe le-ITW. Ngo-1991, i-ITW yafumana umdla weDow kwiI-Zippaklo ntoI-Zippakyaba yinkampani ephethwe ngokupheleleyo yi-ITW. I-Zippak ivelisaiiziphu zeplastikiukwenzela iimakethi yokupakisha ukutyaUkususela kwixesha lokuqaliswa kwayo kude kube namhlanje, iiFlexigrip/Minigrip/Zippak/Dow/Dow Brands zifumene amalungelo awodwa obunikazi angaphezu kwama-300.iiziphu zeplastiki, iingxowa ze-zipper, kunye neendlela kunye noomatshini bokuvelisa okufanayo. Ngo-1997, iDow Chemical yathengisa amalungelo eDowBrands, aquka iZiploc, kwi-SC Johnson ngexabiso eliphakathi kwe-$1.3 kunye ne-$1.7 yeebhiliyoni. I-Zip-Pak yaphuhlisa iiziphu ezihambelana nePolypropylene ngo-2003.

Nangona kunjaloingIZiplockwayeIZippak'sabakhuphisanayo yiPresto, inkampani engaphantsi kweReynolds, kunye nePactiv. Ngo-1995, uHefty, enye yeenkampani zikaReynolds, waphuma ne-sliding.ibhegi ye-zipper.

Iimveliso

IZiploc yandise iimveliso zayo ukuya kuthi ga kwiingxowa zesandwich nje kuphela. Iimveliso zeZiploc ngoku zahlukile kwiingxowa zefriji ukuya kwiikhonteyina ezijijekileyo. Zineengxowa ezisezantsi ezinokwandiswa ezizimeleyo. Zikwanazo neengxowa ezinkulu. Ezi ngxowa zisetyenziselwa ukugcina ukutya kwaye zinkulu kangange-0.61 m × 0.82 m (2 ft x 2.7 ft). Iingxowa ze-zip n' steam zisetyenziselwa ukupheka ukutya kwi-microwave. Iitoti eziguquguqukayo ezenziwe yiIZiploczisetyenziselwa ukugcina ukutya okungekuko kwaye zinkulu kangangeegaloni ezingama-22 zase-US. Kutshanje, iZiploc yenze uluhlu oluphucukileyo lweesandwich kunye neebhegi zokugcina. Zonke iibhegi ezikulo mgca zenziwe ngeplastiki engaphantsi ngama-25% kwaye zenziwe kusetyenziswa amandla omoya. Ibhegi yesandwich yeZiploc Evolve ibe yimpumelelo kangangokuba yabonwa njengeyona "iBalaseleyo kwiMboniso" kwiMbasa zeMveliso eNtsha eziBalaseleyo zika-2010 eCanada.

Intengiso

I-SC Johnson kunye ne-Son basebenzisa intengiso yorhwebo ebhaliweyo, ekwi-intanethi, esebenzisanayo, neboniswa kumabonakude kwimveliso yabo i-Ziploc. Ezi ntengiso zisebenza eBrazil, eJamani, eThailand, e-United States nakwamanye amazwe amaninzi. Intloko yentengiso ye-Ziploc nguScott Heim ophatha iiphulo zabo zentengiso ezixabisa izigidi zeerandi. Ngo-2002, i-SC Johnson & Son yaqalisa iphulo layo elikhulu kwimbali, iphulo elingaphezulu kwezigidi ezingama-50 zeerandi lokuqalisa uluhlu olutsha lweemveliso zetafile/zokugcina ezilahlwayo eziza kuthengiswa phantsi kwegama le-brand ye-Ziploc. I-SC Johnson ithambekele ekujoliseni iiphulo zabo kwicala leentengiso zeTV. Kwiphulo lika-2002, i-$35 yezigidi yanikelwa kwiphulo leTV. Ngo-2015, badale iphulo lentengiso kunye ne-Tough Mudder ukuze bathengisele oomama ngendlela ethintelayo.

Ukuvelisa

Ukuveliswa kweIingxowa zeZiplociyahluka phakathi kweemveliso ezahlukeneyo. UmmiseloIZiplocibhegi yokugcina kunye neyokukhenkceza yenziwe ngeiplastiki ye-polyethylene.

Ukhuphiswano

IZiploc ijongene nokhuphiswano oluqinileyo oluvela kubakhuphisana abanjengoGlad, Hefty, kunye nezinye iivenkile ezininzi ezizimeleyo, ezisetyenziswa ngabantu abaqhelekileyo.iingxowa zeplastikikunye neekhonteyina. Njengoko uJules Rose, usihlalo weSloan's Supermarkets Inc. eNew York City, esitsho: “Le yimarike enokhuphiswano olukhulu enabadlali abaninzi kunye nentengiso yeeleyibhile zabucala ezinamandla ngokungaqhelekanga.” Ngo-1992, iZiploc yajongana nokhuphiswano olukhawulezileyo oluvela kwintengiso eyayikhula ngokukhawuleza yengxowa yeGlad-Lock yeFirst Brands Corporation eyayikhuphisana nayo. Iingxowa zeGlad Lock zanda nge-13.1% kwiiveki ezili-12 ekupheleni kuka-1992, nto leyo eyanika iGlad-Lock isabelo se-18.4% semarike xa kuthelekiswa nesabelo seZiploc sama-43%.
