Bite se ku mateka y'isakoshi ifunze ya zipu?

Mu 1951, hashinzwe ikigo cyitwa Flexigrip, Inc. kugira ngo giteze imbere kandi gitange isokozipu ya pulasitikiizina rimwe. Iyi zipu yari ishingiye ku rutonde rw'ipatanti, zaguzwe n'uwayivumbuye, Borge Madsen. Ibicuruzwa bya mbere bya Flexigrip n'ibindiamazipu ya pulasitiki(nk'ukozipu zitagira imirasire(toptite) byakozwe na Flexigrip) byari ibikoresho byo gupfunyikamo imyenda n'amasakoshi maremare. Nyuma y'aho, ibikorwa byo kwamamaza byibanze ku gupakira ibicuruzwa muriimifuka ya pulasitiki ifite zipu, byaje kuba isoko rikomeye ry'ibicuruzwa bya Flexigrip, Inc.. Mu 1961, Flexigrip, Inc. yabonye ibicuruzwa bivuye ku sosiyete y'Abayapani, Seisan Nippon Sha, yavumbuye ubwoko bwa Minigripagakapu ka pulasitiki gafite zipu, uburenganzira bwihariye bwo gukora no kugurisha muri Leta Zunze Ubumwe za Amerika, bushingiye ku rukurikirane rwazipu ya pulasitikiIpatanti za Seisan. Hashinzwe ikigo gifite izina rimwe kugira ngo gikore kandi gitange isokoAmasakoshi ya MinigripMu mwaka wa 1964 cyangwa ahagana muri uwo mwaka, Minigrip, Inc. yagiranye amasezerano na Dow Chemical Company yo kubona uruhushya rwo gucuruza ibiribwa (supermarkets) ku gicuruzwa cya Minigrip. Byaje kugenda neza cyane.

Muri icyo gihe,imifuka ya pulasitikibyakorerwaga mu bihugu 25 ku muvuduko wa metero 10 ku munota, ariko nta na kimwe cyagurishwaga ku baguzi kuko cyari gihenze cyane ku buryo batagishobora kubikora. Dow yahaye umwe mu bavumbuzi bayo, R. Douglas Behr, inshingano zo guteza imbere uburyo bwihuta kandi bunoze. Kubera ko nta bunararibonye buhagije bari bafite mbere muripulasitiki, akazi kari kagoye kuri Behr ariko yarenze abantu bose ku isi mu mwaka umwe. Ubwo yanozaga uburyo bwo gukora no kongera umuvuduko w’imirongo kugera kuri 60, hanyuma 90, hanyuma 150 ndetse amaherezo na metero 300 ku munota mu 1972, byabaye ngombwa ko ashushanya ibikoresho bishya. Bimwe byahawe uburenganzira bwo gukora ibikoresho naho ibindi bibikwa nk’amabanga y’ubucuruzi na Dow. Amaherezo, abandi bashakashatsi n’abakora ibikoresho, nka tekinisiye wa laboratwari William Shrum n’abandi, bagize uruhare mu iterambere ry’ibikorwa, ariko Behr yakomeje kuba umushakashatsi ukomeye kugeza ubwo yagiye mu kiruhuko cy’izabukuru mu 1993 nk’umuhanga mukuru w’umuhanga. Icyo gihe inyubako y’ubushakashatsi yari “yeguriwe umwuga ukomeye wa R. Douglas Behr”.

Ibyo'Nta gushidikanya ko ari byo. KuvaMu 1978, Minigrip yaguzwe na Signode, Inc. maze iba ishami ry’iyo sosiyete. Mu 1986, Signode na Dow bashinze sosiyete, ari yo Zippak, kugira ngo bateze imbereamasakoshi ya zipuku bicuruzwa by'ibiribwa. Mu 1987, ITW yaguze Signode, maze Minigrip iba ishami rya ITW. Mu 1991, ITW yaguze inyungu za Dow muriZippakikugira ngoZippakiyabaye ishami ryigenga rya ITW. Zippak ikoraamazipu ya pulasitikikuriisoko ry'ibipfunyika by'ibiribwaKuva yashingwa kugeza uyu munsi, Flexigrip/Minigrip/Zippak/Dow/Dow Brands yabonye patenti zisaga 300 zoamazipu ya pulasitiki, amasakoshi ya zipu, n'uburyo n'imashini zo kubikora. Mu 1997, Dow Chemical yagurishije uburenganzira bwa DowBrands, harimo na Ziploc, kuri SC Johnson ku giciro kiri hagati ya miliyari 1.3 na 1.7 z'amadolari y'Amerika. Zip-Pak yakoze zipper zihuye na Polypropylene mu 2003.

Ariko aikigoZiplocnaZippak'sAbahanganye ni Presto, ishami rya Reynolds, na Pactiv. Mu 1995, Hefty, umwe mu masosiyete ya Reynolds, yasohotse afite intsinzi.isakoshi ya zipu.

Ibicuruzwa

Ziploc yaguriye ibicuruzwa byayo ku bindi bitari imifuka ya sandwich gusa. Ibicuruzwa bya Ziploc ubu bitandukanye kuva ku mifuka icunga ibyuma kugeza ku bikoresho bizunguruka. Bafite imifuka yo hasi ishobora kwaguka kandi ihagaze ukwayo. Bafite kandi imifuka minini. Iyi mifuka ikoreshwa mu kubika ibiryo bitari ibiribwa kandi ifite uburebure bwa metero 0.61 × metero 0.82. Imifuka ya zip n'umwuka ikoreshwa mu guteka ibiryo muri mikoroonde. Imifuka yoroshye yakozwe naZiploczikoreshwa mu kubika ibiryo bitari ibiryo kandi zingana na galoni 22 za Amerika. Vuba aha, Ziploc yakoze umurongo wa sandwich n'amasashe yo kubikamo. Amasashe yose ari muri uyu murongo akozwe muri pulasitiki iri munsi ya 25% kandi akorwa hakoreshejwe ingufu z'umuyaga. Amasashe ya sandwich ya Ziploc Evolve yagenze neza cyane ku buryo yafashwe nk'"Iyitwaye neza kurusha ayandi" mu bihembo bya 2010 bya Best New Product Awards muri Kanada.

Kwamamaza

SC Johnson and Son ikoresha iyamamaza ry’ubucuruzi ryanditse, kuri interineti, rihuza abantu, kandi rigaca kuri televiziyo ku bicuruzwa byabo bya Ziploc. Aya matangazo akorera muri: Brezili, Ubudage, Tayilande, Leta Zunze Ubumwe za Amerika n’ahandi henshi. Umuyobozi ushinzwe iyamamaza rya Ziploc ni Scott Heim uyobora ibikorwa byabo byo kwamamaza bigura miliyoni nyinshi z’amadolari. Mu 2002, SC Johnson & Son yatangije ubukangurambaga bwayo bukomeye mu mateka, bukangurambaga burengeje miliyoni 50 z’amadolari bwo gutangiza umurongo mushya w’ibikoresho byo ku meza/ububiko bizagurishwa ku izina rya Ziploc.

Irushanwa

Ziploc ihanganye cyane n'abanywanyi nka Glad, Hefty, n'amaduka menshi y'abikorera ku giti cyabo, asanzwe.imifuka ya pulasitikin'amakonteyineri.
