Ukwethulwa kwe-Frozen Food Packaging Bags

Izigaba eziyinhloko zokudla okuqandisiwe:

Ngokuthuthuka kwamazinga okuphila kanye nesivinini sokuphila esisheshayo, ukunciphisa umsebenzi wasekhishini sekuyizidingo zabantu, futhi ukudla okuqandisiwe kuthandwa abantu ngenxa yobulula bakho, ukushesha, ukunambitheka okumnandi kanye nezinhlobonhlobo ezicebile.Kunezigaba ezine eziyinhloko zokudla okuqandisiwe:
1. Ukudla kwasemanzini okuqandiswe ngokushesha, njengezinhlanzi nezimfanzi, izinti zenkalankala, njll.
2. Izithelo nemifino efriziwe, njengamahlumela e-bamboo, i-edamame, njll.
3. Imfuyo ukudla okuqandiswe ngokushesha njengengulube, inkukhu, njll.
4. Ukufaka ukudla okuqandiswe ngokushesha, okufana namadombolo e-pasta, amadombolo, amabhanisi ashuniwe, amadombolo ezinhlanzi ebhodwe elishisayo, amabhola ezinhlanzi, amabhola okuhlonipha, ama-chicken Nuggets, ama-squid steaks, nezitsha, njll.

isikhwama sokupakisha
Ezinhlotsheni eziningi kangaka zokudla okuqandisiwe, ukuphepha kanye nezinzuzo zokudla okuqandisiwe kuncike ezintweni ezine ezibalulekile:
Okokuqala, izinto zokusetshenziswa zokudla okugayiwe zintsha futhi zisezingeni elihle;
Okwesibili, inqubo yokucubungula ayingcolisi;
Okwesithathu ukupakisha kahle, hhayi ukugqekeza isikhwama ukuze ungcolise;
Eyesine iketango lonke elibandayo.
Ukupakisha kuyingxenye ebalulekile yokudla okuqandisiwe, okuhlobene nokuphepha kokudla, isithunzi senkampani kanye nenzuzo.

Ukupakishwa kokudla okuqandisiwe kufanele kunake ukucatshangelwa:
1. Izindinganiso zokupakisha nemithethonqubo.
Okwesibili, izici zokudla okuqandisiwe nezimo zako zokuvikela.
3. Ukusebenza kanye nobubanzi bokusetshenziswa kwezinto zokupakisha.
4. Ukuma kwemakethe yokudla kanye nezimo zesifunda zokusabalalisa.
5. Umthelela wesakhiwo sonke kanye nempahla yokupakishwa ekudleni okuqandisiwe.
6. Umklamo wesakhiwo sokupakisha esinengqondo kanye nomklamo wokuhlobisa.
Okuyisikhombisa, ukuhlolwa kokupakisha.

Ukupakishwa kokudla okuqandisiwe kufanele kuhlangabezane nezidingo zokujikeleza okukhulu, kusukela ekukhiqizeni, ekuthuthweni kuye ekuthengisweni, ukuze kugcinwe izici zekhwalithi yemikhiqizo eqandisiwe, futhi kuvinjwe ukungcoliswa kwamagciwane nezinto eziyingozi.Ukuthatha amadombolo aqandiswe ngokushesha njengesibonelo, abathengi abaningi benqabile ukuthenga ezinye izinhlobo ngemuva kokusetshenziswa isikhathi esisodwa.Izizathu eziningi ukuthi izinto zokupakisha azilungile, okwenza amadombolo alahlekelwe amanzi, amafutha oxidize kanye nomoya-omile, aphuzi, aqhekeke, acwebe, njll. Iphunga nezinye izinkinga zekhwalithi.

Ukupakishwa kokudla okuqandisiwe kufanele kube nezici ezinhlanu:
1. Kumelwe ibe nezindawo zokuvinjelwa okuphezulu ukuvimbela umkhiqizo ukuthi ungathintani nomoya-mpilo kanye namanzi ashisayo.
2. Ukumelana nomthelela nokumelana nokubhoboza.
3. Ukumelana nokushisa okuphansi, impahla yokupakisha ngeke ikhubaze noma iqhekeke ngisho nasezingeni eliphansi lokushisa -45 °C.
Okwesine, ukumelana nowoyela.
5. Inhlanzeko, ukuvimbela ukufuduka nokungena kwezinto ezinobuthi neziyingozi ekudleni.

Ukupakisha okuguquguqukayo kwepulasitiki okusetshenziswa emkhakheni wokudla okuqandisiwe kuhlukaniswe ikakhulukazi izigaba ezimbili:
Enye ihlanganisa izinto ezihlanganisiwe, lapho izingqimba ezimbili zamafilimu epulasitiki zihlanganiswa ne-adhesive, futhi izinto eziningi ezinamathelayo ziqukethe izinto eziyingozi njenge-ester ne-benzene, ezingangena kalula ekudleni futhi zidale ukungcola.
Eyodwa iphakethe le-multi-layer co-extruded high-barrier.Ikhiqizwa ngezinto zokupakisha eziluhlaza futhi ezivumelana nemvelo, ezinezingqimba ezinhlanu, izendlalelo eziyisikhombisa, nezingqimba eziyisishiyagalolunye.Esikhundleni sokusebenzisa izinto zokunamathisela, ama-extruder angaphezu kwe-3 asetshenziselwa ukuhlanganisa izinto zokusetshenziswa kwe-resin ezinemisebenzi ehlukene efana ne-PA, PE, PP, PET, EVOH Inezici zokungangcoli, isithiyo esiphezulu, amandla aphezulu, isakhiwo esivumelana nezimo, njll. kwenza inqubo yokukhiqiza ukudla okufakwayo kanye nokupakisha kungangcoli.Isibonelo, ukupakisha okunezingqimba eziyisikhombisa okuhlanganisiwe okuhlanganisiwe okuphezulu kwenziwa ngezingqimba ezingaphezu kwezimbili zenayiloni, okuthuthukisa kakhulu amandla okubamba nokudabula kwephakheji.Ukumelana nokushisa okuphezulu nokuphansi, ukumelana nokugcinwa nokuthutha, isitoreji esilula, kungagwema ngokuphumelelayo ukuwohloka kwe-oxidative yokudla kanye nokulahlekelwa kwamanzi, kuvimbela ukukhiqizwa kwe-microbial, ngaleyo ndlela kunwebe impilo yeshalofu yokudla okufriziwe.
