Njengoko sonke sisazi, iingxowa zokupakisha zinokubonwa kuyo yonke indawo kubomi bethu bemihla ngemihla, nokuba kusezivenkileni, kwiivenkile ezinkulu, okanye kumaqonga e-e-commerce. Iingxowa zokutya eziyilwe kakuhle, ezisebenzayo, neziluncedo zinokubonwa kuyo yonke indawo. Isebenza njengokhuselo okanye umqobo wokutya, njenge "suti yokukhusela" yokutya.
Ayinakwenzeka kuphela ukuphepha ngokufanelekileyo izinto ezimbi zangaphandle, ezinje nge-microbial corrosion, ungcoliseko lweekhemikhali, i-oxidation kunye nezinye iingozi, iqinisekisa umgangatho kunye nokhuseleko lokutya ngexesha lokugcinwa kunye nokuthutha, kunye nokwandisa ubomi beshelufu, inokudlala indima yokukhuthaza ukutya. abavelisi, ukubulala iintaka ezininzi ngelitye elinye. . Ke ngoko, ubukhulu becala, iingxowa zokupakisha ziye zaba yinxalenye ebalulekileyo yeemveliso ezahlukahlukeneyo zokutya.
Oku kukwanyuse kakhulu intengiso yeengxowa zokupakisha. Ukuze ufumane indawo kwimakethi yengxowa yokupakisha ukutya, abavelisi abakhulu bayaqhubeka nokuphucula umgangatho wezinto zokupakisha kunye nokufumana iintlobo zeengxowa zokupakisha ukutya. Oku kuzise ukhetho kubenzi bokutya kakhulu.
Nangona kunjalo, ukutya okuhlukeneyo kuneempawu ezahlukeneyo, ngoko ke ukutya okuhlukeneyo kuneemfuno ezahlukeneyo zokukhusela ukupakishwa. Ngokomzekelo, amaqabunga eti athambekele kwi-oxidation, ukufuma kunye nokungunda, ngoko bafuna iingxowa zokupakisha ngokutywinwa kakuhle, umqobo ophezulu we-oksijeni kunye ne-hygroscopicity enhle. Ukuba izinto ezikhethiweyo azihambelani neempawu, umgangatho wamagqabi eti awunakuqinisekiswa.
Ke ngoko, izinto zokupakisha kufuneka zikhethwe ngokwesayensi ngokweempawu ezahlukeneyo zokutya ngokwazo. Namhlanje, i-Pack Mic (i-Shanghai Xiangwei Packaging Co., Ltd) yabelana ngesakhiwo sezinto eziphathekayo kwezinye iingxowa zokupakisha ukutya. Izinto zokupakisha ukutya kwiimarike ziquka ezi zilandelayo. Kwangaxeshanye, izinto ezahlukeneyo ziyadityaniswa ngokweempawu zokutya.
UKUQOKELELWA KWEZINTO EZIPAKIWEYO ZOKUTYA
vI-PET:
I-PET yi-polyethylene terephthalate, eyi-milky emhlophe okanye etyheli ekhanyayo, i-polymer ene-crystalline ephezulu. Ineempawu zokumelana nobushushu obuphezulu, ukuqina okuhle, isiphumo esihle sokushicilela kunye namandla aphezulu.
vPA:
I-PA (Nayiloni, iPolyamide) ibhekisa kwiplastiki eyenziwe ngentlaka yepolyamide. Yimpahla eneempawu ezibalaseleyo zomqobo kwaye ineempawu zokumelana nobushushu obuphezulu, amandla aphezulu, ukuguquguquka, iipropathi zomqobo ezilungileyo, kunye nokumelana nokugqobhoza.
vAL:
I-AL yimathiriyeli yefoyile ye-aluminiyam emhlophe esiliva, ekhanyayo, kwaye inokuthamba okuhle, iipropathi zomqobo, ukutywinwa kobushushu, ukukhusela ukukhanya, ukumelana nobushushu obuphezulu, ukumelana nobushushu obuphantsi, ukumelana neoyile, kunye nokugcinwa kwevumba elimnandi.
vCPP:
Ifilimu ye-CPP iphoswe ngefilimu yepolypropylene, ekwabizwa ngokuba yifilimu eyoluliweyo yepolypropylene. Ineempawu zokumelana nobushushu obuphezulu, ukutywinwa kobushushu obulungileyo, iipropathi ezintle zomqobo, ezingenabuthi kunye nevumba.
vPVDC:
I-PVDC, ekwabizwa ngokuba yi-polyvinylidene chloride, sisixhobo sokuthintela ubushushu obuphezulu esineempawu ezifana nokuxhathisa idangatye, ukuxhathisa umhlwa, kunye nokuqina kakuhle komoya.
vI-VMPET:
I-VMPET yifilimu ye-polyester aluminiyam-egqunywe nge-aluminiyam, eyimathiriyeli eneempawu eziphezulu zokuthintela kwaye ineempawu ezintle zokuthintela ngokuchasene neoksijini, umphunga wamanzi kunye nevumba.
vI-BOPP:
I-BOPP (i-Biaxially Oriented Polypropylene) yinto ebaluleke kakhulu yokupakishwa kwezinto eziguquguqukayo ezineempawu ezingenambala kunye nevumba, amandla aphezulu, amandla empembelelo, ukuqina, ukuqina kunye nokubonakala kakuhle.
vI-KPET:
I-KPET yimathiriyeli eneempawu ezibalaseleyo zomqobo. I-PVDC ifakwe kwi-substrate ye-PET ukuze iphucule iipropati zayo zokuthintela ngokuchasene neegesi ezahlukeneyo, ngaloo ndlela ihlangabezana neemfuno zokupakishwa kokutya okuphezulu.
IZAKHIWO EZAHLUKENEYO ZOKUPAKA UKUTYA
Ibhegi yokupakisha yokubuyisela
Isetyenziselwa ukupakishwa kwenyama, iinkukhu, njl., ukupakishwa kufuna iipropathi ezilungileyo zomqobo, ukuxhathisa ukukrazula, kwaye kunokuvalwa inzala phantsi kweemeko zokupheka ngaphandle kokwaphuka, ukuqhekeka, ukucutheka, kunye nokungabi navumba. Ngokuqhelekileyo, isakhiwo sezinto eziphathekayo kufuneka sikhethwe ngokwemveliso ethile. Ngokomzekelo, iingxowa ezicacileyo zingasetyenziselwa ukupheka, kunye neengxowa ze-aluminium foil zifanelekile ukupheka okuphezulu kokushisa. Indibaniselwano yesakhiwo semathiriyeli ethile:
NgokucacileyoUlwakhiwo lweLaminated:
I-BOPA/CPP, PET/CPP, PET/BOPA/CPP, BOPA/PVDC/CPP, PET/PVDC/CPP, GL-PET/BOPA/CPP
Ifoyile yeAluminiyamimathiriyeli elaminethiweyo Izakhiwo:
PET/AL/CPP, PA/AL/CPP, PET/PA/AL/CPP, PET/AL/PA/CPP
Iingxowa zokupakisha ukutya okune-snack
Ngokubanzi, ukutya okukhukhumeleyo kuhlangabezana neempawu zesithintelo seoksijini, isithintelo samanzi, ukhuseleko lokukhanya, ukumelana neoyile, ukugcinwa kwevumba elimnandi, inkangeleko eqaqambileyo, umbala oqaqambileyo, kunye nexabiso eliphantsi. Ukusetyenziswa kweBOPP/VMCPP indibaniselwano yolwakhiwo lwemathiriyeli inokuhlangabezana neemfuno zokupakishwa kokutya okuphuphumayo.
Ibhegi yokupakisha yebhiskithi
Ukuba iza kusetyenziselwa ukupakisha ukutya okunje ngeebhiskithi, ibhegi yezinto zokupakisha kufuneka ibeneempawu ezintle zokuthintela, iipropathi ezinamandla zokukhusela ukukhanya, ukumelana neoyile, amandla aphezulu, azinavumba kwaye zingenancasa, kunye nokupakishwa okuguquguqukayo. Ngoko ke, sikhetha ukudibanisa izinto eziphathekayo ezifana ne-BOPP / EXPE / VMPET / EXPE / S-CPP.
Ingxowa yokupakisha yomgubo wobisi
Isetyenziselwa ukupakisha umgubo wobisi. Isikhwama sokupakisha kufuneka sihlangabezane neemfuno zobomi beshelufu ende, ukuvumba kunye nokugcinwa kwencasa, ukuchasana ne-oxidation kunye nokuwohloka, kunye nokuchasana nokufunxa ukufuma kunye ne-agglomeration. Ukupakishwa kwepowder yobisi, i-BOPP / VMPET / S-PE isakhiwo sezinto eziphathekayo sinokukhethwa.
Ibhegi yokuPakisha iTea eluhlaza
Kwiibhegi zokupakisha iti, ukuze kuqinisekiswe ukuba amagqabi eti ayawohloka, atshintshe umbala kunye nencasa, khetha iBOPP/AL/PE, BOPP/VMPET/PE, KPET/PE
Ubume bezinto eziphathekayo bunokuthintela ngcono iprotheyini, i-chlorophyll, i-catechin, kunye ne-vitamin C equlethwe kwiti eluhlaza ekubeni i-oxidized.
Ezi zingentla zezinye zezinto zokupakisha ukutya eziqulunqelwe wena nguPack Mic kunye nendlela yokudibanisa iimveliso ezahlukeneyo. Ndiyathemba ukuba iya kuba luncedo kuwe :)
