Iyini isikhwama se-Mylar nokuthi ungayikhetha kanjani?

Ngaphambi kokuthi uthenge imikhiqizo ye-Mylar, lesi sihloko sizokusiza ukuthi ubuyekeze izinto eziyisisekelo futhi uphendule imibuzo ebalulekile ezogxuma iqale iphrojekthi yakho yokupakisha ukudla negiya yakwaMylar. Uma usuphendule le mibuzo, uzokwazi kangcono ukukhetha izikhwama nemikhiqizo ye-Mylar engcono kakhulu yakho kanye nesimo sakho.

 

Siyini isikhwama se-Mylar?

Izikhwama ze-Mylar, mhlawumbe uzwile leli gama ukukhombisa uhlobo lwezikhwama ezisetshenziselwa ukupakisha imikhiqizo yakho. Izikhwama ze-Mylar zingenye yezinhlobo ezivame kakhulu zokupakishwa kwesithiyo, kusukela ku-trail mix kuya ku-protein powder, ukusuka ekhofi kuya ku-hemp. Nokho, abantu abaningi abazi ukuthi iyini iMylar.

Okokuqala, igama elithi "Mylar" empeleni lingelinye lamagama amaningana okuhweba efilimu ye-polyester eyaziwa ngokuthi ifilimu ye-bopp.

Kobuchwepheshe obuyinkimbinkimbi futhi obunokuqonda, imele "i-biaxially oriented polyethylene terephthalate."

Yathuthukiswa yi-DuPont ngeminyaka yawo-1950s, ifilimu ekuqaleni yayisetshenziswa yi-NASA ngezingubo zokulala ze-Mylar kanye nokugcina isikhathi eside ngoba yandisa impilo yeshalofu yokudla ngokumunca umoya-mpilo. Khetha i-aluminium foil enamandla kakhulu.

Kusukela ngaleso sikhathi, i-Mylar ibilokhu isetshenziswa kabanzi ngenxa yamandla ayo aphezulu okuqina kanye nezindawo zayo zomlilo, ukukhanya, igesi kanye nephunga.

I-Mylar iphinde ibe yi-insulator enhle ngokumelene nokuphazamiseka kukagesi, yingakho isetshenziselwa ukwenza izingubo zokulala eziphuthumayo.

Kuzo zonke lezi zizathu nokunye, izikhwama ze-Mylar zibhekwa njengezinga legolide lokugcina ukudla isikhathi eside.

Yiziphi izinzuzo ze-Mylar?

Amandla aphezulu aqinile, ukumelana nezinga lokushisa, ukuzinza kwamakhemikhali, ukuvikelwa emagesini, iphunga, nokukhanya kuyizici eziyingqayizivele ezenza i-Mylar ibe inombolo eyodwa yokugcina ukudla isikhathi eside.

Kungakho ubona imikhiqizo eminingi yokudla epakishwe ezikhwameni ze-Mylar ezinensimbi ezaziwa ngokuthi yizikhwama ze-foil ngenxa yongqimba lwe-aluminium kuzo.

Ukudla kuzohlala isikhathi esingakanani ezikhwameni ze-Mylar?

Ukudla kungahlala amashumi eminyaka ezikhwameni zakho zeMylar, kodwa lokhu kuncike kakhulu ezintweni ezi-3 ezibaluleke kakhulu okuyilezi:

1. Isimo sesitoreji

2. Uhlobo lokudla

3. Uma ukudla kuvalwe kahle.

Lezi zici ezi-3 ezibalulekile zizonquma isikhathi nempilo yakho yokudla lapho kugcinwa nesikhwama se-Mylar. Ngokudla okuningi okufana nezimpahla ezisemathinini, isikhathi sazo sokuqinisekisa silinganiselwa eminyakeni eyi-10, kuyilapho ukudla okomiswe kahle okunjengobhontshisi nokusanhlamvu kungahlala iminyaka engu-20-30.

Lapho ukudla kuvaleke kahle, usesimweni esingcono sokuthola isikhathi eside ngisho nangaphezulu.

Yiziphi izinhloboUkudla okungafanele kuhlanganiswe neMylar?

– Noma yini enomswakama ongu-10% noma ngaphansi kufanele igcinwe ezikhwameni zeMylar. Futhi, izithako ezinomswakama ongu-35% noma ngaphezulu zingakhuthaza i-botulism ezindaweni ezingenamoya ngakho-ke zidinga ukufakwa ku-pasteurized. Kudingeka kucaciswe ukuthi imizuzu eyi-10 yokuncelisa ibele ibhubhisa ubuthi be-botulinum. Kodwa-ke, uma uhlangana nephasela elinamandle (okusho ukuthi amagciwane akhula ngaphakathi futhi akhiqiza ubuthi) ungakudli okuphakathi kwesikhwama! Sicela uqaphele, sinikeza ama-substrates efilimu okuyisinqumo esihle kakhulu sezinto zokudla ezinomswakama. Xhumana nathi ukuze uthole imininingwane eyengeziwe. 

– Izithelo nemifino kungagcinwa kodwa kuphela uma kungaqandisiwe.

– Ubisi, inyama, isithelo kanye nesikhumba kuzoshintsha kushintshe isikhathi eside.

Izinhlobo ezahlukene ze-Mylar Bags kanye nokusetshenziswa kwazo

Isikhwama esiphansi

Kunezikhwama zeMylar eziyisikwele ngokuma. Banomshini ofanayo wokusebenza nokuvala, kodwa ukwakheka kwawo kuhlukile.

Ngamanye amazwi, uma ugcwalisa futhi uvala lesi sikhwama se-Mylar, kunesikwele esiyisicaba noma isikhala esingunxande ngezansi. Izikhwama zilungele ukusetshenziswa kwansuku zonke, ikakhulukazi lezo okunzima ukuzigcina ezitsheni.

Kungenzeka ukuthi ubabonile bepakisha itiye, amakhambi, neminye imikhiqizo eyomisiwe yensangu.

Izikhwama Zokumisa

I-stand-up Mylars ayihlukani kakhulu nezikhwama zezinkinobho eziyisicaba. Banomgomo ofanayo wokusebenza kanye nokusebenzisa.

Umehluko kuphela ukuma kwalezi zikhwama. Ngokungafani nezikhwama ezingezansi eziyisikwele, i-Mylar yokuma ayinamkhawulo. Iphansi labo lingaba yindilinga, i-oval, noma isikwele noma unxande ngesimo.

Izikhwama ze-Mylar ezingazweli ezinganeni

Isikhwama se-Mylar esingamelani nezingane simane siyinguqulo ethuthukisiwe yesikhwama se-Mylar esijwayelekile. Lezi zikhwama zingavalwa ngevacuum, ilokhi uziphu nanoma yiluphi olunye uhlobo lwesikhwama se-Mylar, umehluko kuphela indlela yokukhiya eyengeziwe eqinisekisa ukuthi akukho ukuchithwa noma ukufinyelela kwengane kokuphakathi.

Ilokhi entsha yokuphepha iqinisekisa nokuthi ingane yakho ayikwazi ukuvula isikhwama seMylar.

Sula izikhwama ze-Mylar ze-foil ngaphambili nangemuva

Uma udinga isikhwama se-Mylar esingavikeli nje kuphela umkhiqizo wakho, kodwa futhi esikuvumela ukuthi ubone ukuthi yini engaphakathi, khetha isikhwama se-Mylar sewindi. Lesi sitayela sesikhwama se-Mylar sinokubukeka kwezendlalelo ezimbili. Uhlangothi olungemuva lukhanya ngokuphelele, kuyilapho ingaphambili libonisa ngale ngokuphelele noma ngokwengxenye, njengefasitela.

Kodwa-ke, ukukhanya kwenza umkhiqizo ube lula ekulimaleni okukhanyayo. Ngakho-ke, ungasebenzisi lezi zikhwama ngezinhloso zokugcina isikhathi eside.

Zonke izikhwama ngaphandle kwe-vacuum yezikhwama ze-Mylar zinezingidi zoziphu.

Isiphetho

Lesi isingeniso sezikhwama ze-Mylar, ngethemba ukuthi lesi sihloko siwusizo kini nonke.

Ngiyabonga ngokufunda.
