Amateka yiterambere yimifuka ipakira

Umufuka wapakiratekinoloji yatangiriye mu myaka ya za 40, kuva 50 ya firime ya pulasitike ikoreshwa neza mugupakira ibicuruzwa, tekinoroji ya vacuum yamashanyarazi yatejwe imbere byihuse.Urwego rwo gupakira kurwego runaka rugaragaza urwego rwa siyanse n'ikoranabuhanga n'ubutunzi bw'igihugu.Ubushakashatsi no gukoresha ibikoresho byubushakashatsi bwa vacuum mubushinwa biracyari mu ntangiriro.
Ubwa mbere, mu 1962, Ordal yasabye firime idashobora kwangirika irashobora gukura kwa mikorobe itera indwara, gupakira inyama nshya bishobora kongera ubuzima bwayo.
Icya kabiri, Baltzer ko imifuka yo gupakira vacuum yuzuye inyama zipfunyitse mu kirere igihe kirekire kubera impamvu zikurikira: (1) umubare wa mikorobe yose mubihe bya anaerobic wiyongera buhoro;(2) kubora no kugabanuka;.Ibi byerekana ko firime vacuum idashobora gupakira inyama nshya, mugihe ogisijene irimo ihindurwamo dioxyde de carbone, firime idashobora kwangirika kugirango yongere kwinjira muri paki, bityo igikapu cyo gupakira vacuum gishobora kwongerera ubuzima bwinyama nshya.
Icya gatatu, mu 1970, Pierson hamwe nibindi byifuzo byo gupakira vacuum kugirango habeho gutoranya amoko ya mikorobe ninzego za "ecosystem".1974 Isosiyete ya SCOPA yabanje gukoresha MAP (ModifiedAtmospherePackage, ni icyuho mbere, hanyuma Mu 1974, SCOPA yabanje gukoresha MAP (Modified AtmospherePackage, ni ubwoko bwo gupakira bwabanje gukururwa hanyuma bukuzuzwa ijanisha runaka rya gaze ivanze) kugirango bapakire ibikomoka ku nyama.
Icya kane, Pesi n'abandi.(1986) yabisabyeimifuka yo gupakiranuburyo bwiza bwo gukomeza ubwiza nubukomezi bwo kubika imbuto za perimoni.Ibi birerekana ko iterambere no gukundwa muburyo bwo kubika no kubungabunga bigenda bihabwa agaciro nababikora, abakora n'abaguzi.Ikindi gice cyibikoresho bikenerwa mu gupakira vacuum ni ibikoresho byo gupakira, ibikoresho byo gupakira mubwoko bwinshi, hariho plastike, plastike nimpapuro, feri ya aluminium nibindi bikoresho bigizwe nibice, amacupa yikirahure, ibyuma hamwe na plastiki ikomeye, nibindi, nibindi, guhitamo ibikoresho byo gupakira bigomba gushingira kumiterere yibiribwa bipfunyitse, nkibiryo byabitswe bikoreshwa mumacupa yikirahure cyangwa amabati, nkimiti yimiti yubushinwa hamwe na aluminium foil cyangwa plastike, nibindi .. Nubwo hariho ubwoko bwinshi bwa ibikoresho bya kontineri yo gupakira vacuum, ariko ibisanzwe ni firime ya plastike.
Hamwe n’iterambere ry’ubukungu bw’isi yose, Ubushinwa buza ku isonga mu gukora inganda za pulasitike kugira ngo "zibe umuyobozi w’inganda zipakurura ibintu byoroshye", nkintego, gukomeza kwiteza imbere, guhanga udushya, kandi dutegerezanyije amatsiko gukorana na benshi mu bo bakorana mu gihugu ndetse no mu mahanga kugira ngo dushyireho. ejo hazaza heza.
