Njengoko sonke sisazi, iingxowa zokupakisha zinokubonwa kuyo yonke indawo kubomi bethu bemihla ngemihla, nokuba kusezivenkileni, kwiivenkile ezinkulu, okanye kumaqonga e-e-commerce. Iingxowa ezahlukeneyo zokupakisha ukutya eziyilwe kakuhle, ezisebenzayo, nezilula zinokubonwa kuyo yonke indawo. Zisebenza njengomaleko wokukhusela okanye wokuthintela ukutya, njenge "suti yokukhusela" yokutya.
Ayinakuphepha nje kuphela izinto ezimbi zangaphandle, ezinje ngokugqwala kweentsholongwane, ungcoliseko lweekhemikhali, i-oxidation kunye nezinye iingozi, iqinisekise umgangatho kunye nokhuseleko lokutya ngexesha lokugcina nokuthuthwa, kwaye yandise ixesha lokuhlala kwayo eshelufini, ingadlala indima yokukhuthaza abavelisi bokutya, ibulala iintaka ezininzi ngelitye elinye. . Ke ngoko, ubukhulu becala, iingxowa zokupakisha ziye zaba yinxalenye ebalulekileyo yeemveliso ezahlukeneyo zokutya.
Oku kukwanyuse kakhulu imarike yeengxowa zokupakisha. Ukuze zithathe indawo kwimarike yeengxowa zokupakisha ukutya, abavelisi abakhulu bayaqhubeka nokuphucula umgangatho wezixhobo zokupakisha kwaye bafumana iintlobo ngeentlobo zeengxowa zokupakisha ukutya. Oku kukwazise ukhetho olukhulu kubavelisi bokutya.
Nangona kunjalo, ukutya okwahlukileyo kuneempawu ezahlukeneyo, ngoko ke ukutya okwahlukileyo kuneemfuno ezahlukeneyo zokukhusela xa kupakishwa. Umzekelo, amagqabi eti athanda ukubola, ukufuma kunye nokungunda, ngoko ke afuna iingxowa zokupakisha ezinesivalo esihle, umqobo ophezulu weoksijini kunye ne-hygroscopicity elungileyo. Ukuba izinto ezikhethiweyo azihlangabezani neempawu, umgangatho wamagqabi eti awunakuqinisekiswa.
Ngoko ke, izinto zokupakisha kufuneka zikhethwe ngokwesayensi ngokweempawu ezahlukeneyo zokutya ngokwako. Namhlanje, iPack Mic (Shanghai Xiangwei Packaging Co., Ltd) yabelana ngesakhiwo sezinto ezithile zeengxowa zokupakisha ukutya. Izinto zokupakisha ukutya ezikwimarike ziquka ikakhulu oku kulandelayo. Kwangaxeshanye, izinto ezahlukeneyo zihlanganiswa ngokweempawu zokutya.
INGQOKELELO YEZIXHOBO ZOKUPHAKISHA UKUTYA
vIsilwanyana sasekhaya:
I-PET yi-polyethylene terephthalate, eyi-polymer emhlophe okanye etyheli ekhanyayo, enekristale ephezulu. Ineempawu zokumelana nobushushu obuphezulu, ukuqina okuhle, isiphumo esihle sokuprinta kunye namandla aphezulu.
vI-PA:
I-PA (Nylon, Polyamide) ibhekisa kwiplastiki eyenziwe nge-polyamide resin. Yinto eneempawu ezintle kakhulu zokuthintela kwaye ineempawu zokumelana nobushushu obuphezulu, amandla aphezulu, ukuguquguquka, iimpawu ezilungileyo zokuthintela, kunye nokumelana nokubhoboza.
vAL:
I-AL yinto eyenziwe ngefoyile ye-aluminiyam emhlophe njengesilivere, ekhanyayo, kwaye ithambile kakuhle, ineempawu zokuthintela, ivala ubushushu, ikhusela ukukhanya, imelana nobushushu obuphezulu, imelana nobushushu obuphantsi, imelana neoyile, kwaye igcina ivumba elimnandi.
vI-CPP:
Ifilimu ye-CPP yifilimu ye-polypropylene ephosiweyo, eyaziwa ngokuba yifilimu ye-polypropylene eyoluliweyo. Ineempawu zokumelana nobushushu obuphezulu, ukuvaleka kakuhle kobushushu, iimpawu ezilungileyo zokuthintela, ayinatyhefu kwaye ayinavumba.
vI-PVDC:
I-PVDC, ekwaziwa ngokuba yi-polyvinylidene chloride, yinto ethintela ubushushu obuphezulu eneempawu ezifana nokumelana nomlilo, ukumelana nokugqwala, kunye nokuqina komoya okuhle.
vI-VMPET:
I-VMPET yifilimu egqunywe nge-aluminium eyenziwe nge-polyester, eyinto eneempawu zokuthintela eziphezulu kwaye ineempawu zokuthintela ezilungileyo kwi-oksijini, umphunga wamanzi kunye nevumba.
vI-BOPP:
I-BOPP (i-Biaxially Oriented Polypropylene) sisixhobo sokupakisha esibaluleke kakhulu nesiguquguqukayo esineempawu zokungabi nambala nokungavumba, amandla aphezulu okutsalwa, amandla okuchaphazeleka, ukuqina, ukuqina kunye nokubonakala kakuhle.
vI-KPET:
I-KPET yinto eneempawu ezintle kakhulu zokuthintela. I-PVDC igqunywe kwi-PET substrate ukuphucula iimpawu zayo zokuthintela kwiigesi ezahlukeneyo, ngaloo ndlela ihlangabezana neemfuno zokupakisha ukutya okuphezulu.
IINDLELA EZAHLUKENEYO ZOKUPAKISHA UKUTYA
Ingxowa yokupakisha yokujika
Isetyenziselwa ukupakisha inyama, iinkukhu, njl.njl., ukupakisha kufuna iimpawu ezintle zokuthintela, ukumelana nokukrazuka, kwaye kunokucoca iintsholongwane phantsi kweemeko zokupheka ngaphandle kokuqhekeka, ukuqhekeka, ukuncipha, kunye nokungabi navumba. Ngokubanzi, ulwakhiwo lwezinto kufuneka lukhethwe ngokwemveliso ethile. Umzekelo, iingxowa ezibonakalayo zingasetyenziselwa ukupheka, kwaye iingxowa zefoyile ye-aluminium zifanelekile ukupheka kubushushu obuphezulu. Umxube wesakhiwo sezinto ezithile:
EcacileyoIzakhiwo Ezilaminethiweyo:
I-BOPA/CPP, i-PET/CPP, i-PET/BOPA/CPP, i-BOPA/PVDC/CPP, i-PET/PVDC/CPP, i-GL-PET/BOPA/CPP
Ifoyile yealuminiyamizinto ezilaminethiweyo Izakhiwo:
I-PET/AL/CPP, PA/AL/CPP, I-PET/PA/AL/CPP, I-PET/AL/PA/CPP
Iingxowa zokupakisha ukutya okunesidlo esincinci ezikhukhumeleyo
Ngokubanzi, ukutya okufumileyo kuhambelana kakhulu neempawu zomqobo weoksijini, umqobo wamanzi, ukhuseleko lokukhanya, ukumelana neoyile, ukugcinwa kwevumba elimnandi, inkangeleko ecacileyo, umbala oqaqambileyo, kunye nexabiso eliphantsi. Ukusetyenziswa kwendibaniselwano yesakhiwo sezinto zeBOPP/VMCPP kunokuhlangabezana neemfuno zokupakisha ukutya okufumileyo.
Ibhegi yokupakisha yebhisikithi
Ukuba iza kusetyenziselwa ukupakisha ukutya okufana neebhisikithi, ibhegi yezinto zokupakisha kufuneka ibe neempawu ezintle zokuthintela, iimpawu zokukhusela ukukhanya ezinamandla, ukumelana neoyile, amandla aphezulu, ayinavumba kwaye ayinancasa, kwaye ipakishwe ngokuguquguquka. Ke ngoko, sikhetha umxube wezakhiwo zezinto ezifana neBOPP/EXPE/VMPET/EXPE/S-CPP.
Ingxowa yokupakisha yomgubo wobisi
Isetyenziselwa ukupakisha umgubo wobisi. Ingxowa yokupakisha kufuneka ihlangabezane neemfuno zobomi obude, ivumba elimnandi kunye nokugcinwa kwencasa, ukumelana ne-oxidation kunye nokuwohloka, kunye nokumelana nokufunxwa komswakama kunye nokuhlangana. Kwiphakheji yomgubo wobisi, ulwakhiwo lwezinto zeBOPP/VMPET/S-PE lunokukhethwa.
Ingxowa yokuPakisha yeTi eluhlaza
Kwiingxowa zokupakisha iti, ukuqinisekisa ukuba amagqabi eti ayawohloka, atshintsha umbala kunye nencasa, khetha i-BOPP/AL/PE, i-BOPP/VMPET/PE, i-KPET/PE
Ulwakhiwo lwezinto lunokuthintela ngcono iproteni, i-chlorophyll, i-catechin, kunye ne-vitamin C ekwiti eluhlaza ukuba ingangcoliswa.
Ezi zingentla zezinye zezinto zokupakisha ukutya eziqokelelwe yiPack Mic kunye nendlela yokudibanisa iimveliso ezahlukeneyo. Ndiyathemba ukuba ziya kukunceda :)
