Ukwaziswa kweFrozen Food Packaging Bags

Iindidi eziphambili zokutya okukhenkcezisiweyo:

Ngokuphucuka kwemigangatho yokuphila kunye nesantya esikhawulezayo sobomi, ukunciphisa umsebenzi wasekhitshini kuye kwaba ziimfuno zabantu, kwaye ukutya okukhenkcezisiweyo kuthandwa ngabantu ngenxa yoncedo, ukukhawulezisa, incasa emnandi kunye neentlobo ezahlukeneyo ezityebileyo.Kukho iindidi ezine eziphambili zokutya okukhenkcezisiweyo:
1. Ukutya kwamanzi okukhenkcezayo ngokukhawuleza, njengentlanzi kunye ne-shrimp, iintonga zoononkala, njl.
2. Iziqhamo kunye nemifuno ekhenkcezisiweyo, njengamahlumela e-bamboo, i-edamame, njl.
3. Imfuyo yokutya okukhenkcezayo ngokukhawuleza, okufana nehagu, inkukhu, njl.
4. Ukulungisa ukutya okukhenkcezisiweyo okukhawulezayo, okufana namadombolo e-pasta, amadombolo, i-squid buns, i-hot pot fish dumplings, iibhola zentlanzi, iibhola ze-tribute, i-chicken nuggets, i-squid steaks, kunye nezitya, njl.

ibhegi yokupakisha
Kwiintlobo ezininzi zokutya okukhenkcezisiweyo, ukhuseleko kunye noncedo lokutya okufakwe emkhenkceni kuxhomekeke kwizinto ezine eziphambili:
Okokuqala, izinto ezikrwada zokutya okucutshungulwayo zintsha kwaye zisemgangathweni olungileyo;
Okwesibini, inkqubo yokucubungula ayinangcoliseko;
Okwesithathu kukupakisha kakuhle, kungekhona ukuqhekeza ingxowa ukungcolisa;
Eyesine litsheyini elibandayo lonke.
Ukupakishwa yinxalenye ebalulekileyo yokutya okunomkhenkce, okunxulumene nokhuseleko lokutya, isidima senkampani kunye nenzuzo.

Ukupakishwa kokutya okukhenkcezisiweyo kufuneka kuthathelwe ingqalelo ingqwalasela:
1. Imigangatho yokupakisha kunye nemimiselo.
Okwesibini, iimpawu zokutya okufriziwe kunye neemeko zokukhusela.
3. Ukusebenza kunye nobubanzi bokusetyenziswa kwezinto zokupakisha.
4. Ukubekwa kwemarike yokutya kunye neemeko zokujikeleza kwengingqi.
5. Impembelelo yesakhiwo esipheleleyo kunye nempahla yokupakishwa kokutya okufriziwe.
6. Uyilo lwesakhiwo sokupakisha esinengqiqo kunye noyilo lokuhombisa.
Isixhenxe, uvavanyo lokupakisha.

Ukupakishwa kokutya okunomkhenkce kufuneka kuhlangabezane neemfuno zokujikeleza okukhulu, ukusuka kwimveliso, ukuthuthwa ukuya ekuthengisweni, ukugcina iimpawu zomgangatho weemveliso ezikhenkcezisiweyo, kunye nokuthintela ukungcoliseka kweebhaktheriya kunye nezinto ezinobungozi.Ukuthatha i-dumplings ekhenkcezayo ngokukhawuleza njengomzekelo, abathengi abaninzi bakuchasile ukuthenga ezinye iimveliso emva kokusetyenziswa kwexesha elinye.Uninzi lwezizathu kukuba izinto zokupakisha azilungile, zibangela ukuba amadombolo alahlekelwe ngamanzi, ioli ye-oxidize kunye ne-air-dry, ijika iphuzi, i-crack, i-crusty, njl. Ivumba kunye nezinye iingxaki zekhwalithi.

Ukupakishwa kokutya okukhenkcezisiweyo kufuneka kube neempawu ezintlanu:
1. Kufuneka ibe neepropati eziphezulu zokuthintela ukuthintela umkhiqizo ukuba udibanise ne-oksijini kunye namanzi avuthayo.
2. Ukuchasana kwempembelelo kunye nokuchasana nokubhoboza.
3. Ukumelana nokushisa okuphantsi, izinto zokupakisha aziyi kuphazamisa okanye ziqhekeke nakwiqondo lokushisa eliphantsi -45 °C.
Okwesine, ukuxhathisa kweoli.
5. Ucoceko, ukuthintela ukufuduka kunye nokungena kwezinto ezinobuthi kunye nezinobungozi ekudleni.

Ukupakishwa kwePlastiki eguquguqukayo esetyenziswa kwibala lokutya okukhenkcezisiweyo kohlulwe kakhulu kube ziindidi ezimbini:
Enye yeyokupakishwa kwezinto eziyintlanganisela, apho iileya ezimbini zeefilim zeplastiki zidityaniswa kunye nokuncamathelisa, kwaye uninzi lwezincamathelisi ziqulethe izinto eziyingozi ezinjengeesters kunye nebenzene, ezinokungena lula ekutyeni kwaye zibangele ungcoliseko.
Enye yeyokupakishwa kwe-multi-layer co-extruded high-barrier package.Iveliswa ngezinto zokupakisha eziluhlaza kunye nezokusingqongileyo, ezinemigangatho emihlanu, iileya ezisixhenxe, kunye neeleya ezilithoba.Esikhundleni sokusebenzisa i-adhesives, ngaphezu kwe-3 extruders isetyenziselwa ukudibanisa izinto eziluhlaza ze-resin kunye nemisebenzi eyahlukeneyo efana ne-PA, PE, PP, PET, EVOH Ineempawu zokungangcolisi, umqobo ophezulu, amandla aphezulu, isakhiwo esiguquguqukayo, njl. yenza inkqubo yemveliso yokupakishwa kokutya kunye nemathiriyeli yokupakisha ingangcoliseki.Ngokomzekelo, i-sex-layer co-extruded high-barrier packaging iqulethwe ngamacandelo angaphezu kwembini ye-nylon, ephucula kakhulu amandla okunyamezela kunye nokukrazula kwepakethe.Ukumelana nokushisa okuphezulu kunye nokuphantsi, ukugcinwa kunye nokumelana nokuthutha, ukugcinwa okulula, kunokuphepha ngokufanelekileyo ukuchithwa kwe-oxidative yokutya kunye nokulahlekelwa kwamanzi, ukuvimbela ukuveliswa kwe-microbial, ngaloo ndlela ukwandisa ubomi beshelufu yokutya okufriziwe.
