E like me kā kākou e ʻike nei, hiki ke ʻike ʻia nā ʻeke ʻōpala ma nā wahi āpau o ko kākou ola o kēlā me kēia lā, inā paha ma nā hale kūʻai, nā supermarkets, a i ʻole nā kahua e-commerce. Hiki ke ʻike ʻia nā ʻeke ʻōpala meaʻai like ʻole i hoʻolālā nani ʻia, pono, a maʻalahi hoʻi ma nā wahi āpau. Hana ia ma ke ʻano he pale a pale paha no ka meaʻai, e like me ka "pale pale" no ka meaʻai.
ʻAʻole hiki iā ia ke pale pono i nā mea ʻino o waho, e like me ka microbial corrosion, ka haumia kemika, ka oxidation a me nā pōʻino ʻē aʻe, e hōʻoia i ka maikaʻi a me ka palekana o ka meaʻai i ka wā e mālama ai a me ka halihali ʻana, a hoʻolōʻihi i kona ola papa, hiki iā ia ke pāʻani i kahi kuleana hoʻolaha no nā mea hana meaʻai, e pepehi ana i nā manu he nui me ka pōhaku hoʻokahi. . No laila, i kahi nui, ua lilo nā ʻeke hoʻopili i ʻāpana koʻikoʻi o nā huahana meaʻai like ʻole.
Ua hoʻoikaika nui kēia i ka mākeke no nā ʻeke ʻōpala. I mea e noho ai i kahi ma ka mākeke ʻeke ʻōpala meaʻai, hoʻomau nā mea hana nui i ka hoʻomaikaʻi ʻana i ka maikaʻi o nā mea ʻōpala a loaʻa nā ʻano ʻeke ʻōpala meaʻai like ʻole. Ua lawe mai kēia i nā koho i nā mea hana meaʻai i kahi nui.
Eia nō naʻe, he ʻokoʻa nā ʻano o nā meaʻai like ʻole, no laila he ʻokoʻa nā koi palekana no ka hoʻopili ʻana i nā meaʻai like ʻole. No ka laʻana, he maʻalahi nā lau kī i ka oxidation, ka makū a me ka ʻōpala, no laila pono lākou i nā ʻeke hoʻopili me ka sila maikaʻi, ka pale oxygen kiʻekiʻe a me ka hygroscopicity maikaʻi. Inā ʻaʻole kūlike ka mea i koho ʻia me nā ʻano, ʻaʻole hiki ke hōʻoia ʻia ka maikaʻi o nā lau kī.
No laila, pono e koho ʻia nā mea hoʻopili ʻana ma ke ʻano ʻepekema e like me nā ʻano like ʻole o ka meaʻai ponoʻī. I kēia lā, ke kaʻana like nei ʻo Pack Mic (Shanghai Xiangwei Packaging Co., Ltd) i ke ʻano o kekahi mau ʻeke hoʻopili meaʻai. ʻO nā mea hoʻopili meaʻai ma ka mākeke e komo pū me kēia mau mea. I ka manawa like, ua hoʻohuihui ʻia nā mea like ʻole e like me nā ʻano o ka meaʻai.
Hōʻiliʻili Mea ʻAi no ka ʻUhi ʻana
vHOLOHOLONA:
ʻO PET ka polyethylene terephthalate, he polymer keʻokeʻo waiū a melemele māmā paha, he crystalline kiʻekiʻe. Loaʻa iā ia nā ʻano o ke kūpaʻa wela kiʻekiʻe, ka paʻakikī maikaʻi, ka hopena paʻi maikaʻi a me ka ikaika kiʻekiʻe.
vPA:
ʻO PA (Nylon, Polyamide) e pili ana i kahi palakiko i hana ʻia me ka resin polyamide. He mea ia me nā waiwai pale maikaʻi loa a he mau ʻano o ke kūpaʻa wela kiʻekiʻe, ka ikaika kiʻekiʻe, ka maʻalahi, nā waiwai pale maikaʻi, a me ke kūpaʻa ʻana i ka puncture.
vAL:
He mea pepa alumini ʻo AL keʻokeʻo kālā, he ʻālohilohi, a he palupalu maikaʻi, nā waiwai pale, ka hiki ke sila i ka wela, ka pale māmā, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa wela haʻahaʻa, ke kūpaʻa aila, a me ka paʻa ʻana o ke ʻala.
vCPP:
ʻO ka ʻili CPP he ʻili polypropylene i hoʻolei ʻia, i ʻike ʻia hoʻi he ʻili polypropylene i hoʻolōʻihi ʻia. Loaʻa iā ia nā ʻano o ke kūpaʻa wela kiʻekiʻe, ka sila wela maikaʻi, nā waiwai pale maikaʻi, ʻaʻohe mea ʻawahia a ʻaʻohe ʻala.
vPVDC:
ʻO PVDC, i ʻike ʻia hoʻi ʻo polyvinylidene chloride, he mea pale wela kiʻekiʻe me nā ʻano e like me ke kūpaʻa lapalapa, ke kūpaʻa i ka pala, a me ka paʻa maikaʻi o ka ea.
vVMPET:
ʻO VMPET ka ʻili polyester i uhi ʻia i ka alumini, he mea ia me nā waiwai pale kiʻekiʻe a he mau waiwai pale maikaʻi kona e kūʻē i ka oxygen, ka mahu wai a me ke ʻala.
vBOPP:
ʻO BOPP (Biaxially Oriented Polypropylene) kahi mea hoʻopili palupalu koʻikoʻi me nā hiʻohiʻona o ke kala ʻole a me ka ʻala ʻole, ka ikaika tensile kiʻekiʻe, ka ikaika hopena, ka paʻakikī, ka paʻakikī a me ka transparency maikaʻi.
vKPET:
He mea hana ʻo KPET me nā waiwai pale maikaʻi loa. Uhi ʻia ka PVDC ma luna o ka substrate PET e hoʻomaikaʻi i kona mau waiwai pale e kūʻē i nā kinoea like ʻole, no laila e hoʻokō ai i nā koi o ka hoʻopili meaʻai kiʻekiʻe.
Nā ʻano hoʻopili meaʻai like ʻole
ʻEke hoʻopili Retort
Hoʻohana ʻia no ka hoʻopili ʻana i ka ʻiʻo, ka moa, a me nā mea ʻē aʻe, pono ka ʻōpala i nā waiwai pale maikaʻi, ke kūpaʻa i ka haehae, a hiki ke hoʻomaʻemaʻe ʻia ma lalo o nā kūlana kuke me ka ʻole o ka haki ʻana, ka nahā ʻana, ka emi ʻana, a me ka ʻala ʻole. Ma ke ʻano laulā, pono e koho ʻia ke ʻano o ka mea e like me ka huahana kikoʻī. No ka laʻana, hiki ke hoʻohana ʻia nā ʻeke moakaka no ka kuke ʻana, a kūpono nā ʻeke pepa alumini no ka kuke ʻana i ka mahana kiʻekiʻe. Hoʻohuihui ʻano mea kikoʻī:
MoakakaNā Hale i Hoʻopaʻa ʻia:
BOPA/CPP, PET/CPP, PET/BOPA/CPP, BOPA/PVDC/CPP, PET/PVDC/CPP, GL-PET/BOPA/CPP
Pepa alumininā mea i hoʻopaʻa ʻia:
PET/AL/CPP, PA/AL/CPP, PET/PA/AL/CPP, PET/AL/PA/CPP
Nā ʻeke ʻeke meaʻai māmā i puhi ʻia
Ma keʻano laulā, ʻo ka meaʻai puffed e hoʻokō nui i nā ʻano o ka pale oxygen, ka pale wai, ka pale māmā, ke kūpaʻa ʻaila, ka paʻa ʻana o ka ʻala, ke ʻano ʻoi, ke kala ʻālohilohi, a me ke kumukūʻai haʻahaʻa. ʻO ka hoʻohana ʻana i ka hui pū ʻana o ka hoʻonohonoho mea BOPP/VMCPP hiki ke hoʻokō i nā pono o ka hoʻopili ʻana o nā meaʻai māmā puffed.
ʻEke ʻeke pōpō
Inā e hoʻohana ʻia no ka hoʻopili ʻana i ka meaʻai e like me nā biscuits, pono i ka ʻeke mea hoʻopili ke loaʻa nā waiwai pale maikaʻi, nā waiwai pale māmā ikaika, ke kūpaʻa ʻana i ka ʻaila, ka ikaika kiʻekiʻe, ʻaʻohe ʻala a me ka ʻono ʻole, a me ka hoʻopili palupalu. No laila, koho mākou i nā hui hoʻonohonoho mea e like me BOPP/EXPE/VMPET/EXPE/S-CPP.
ʻEke ʻeke pauka waiū
Hoʻohana ʻia ia no ka hoʻopili ʻana i ka pauka waiū. Pono ka ʻeke hoʻopili e hoʻokō i nā koi o ke ola lōʻihi, ka mālama ʻana i ka ʻala a me ka ʻono, ke kūʻē ʻana i ka oxidation a me ka palaho, a me ke kūʻē ʻana i ka omo ʻana o ka makū a me ka hoʻopili ʻana. No ka hoʻopili ʻana i ka pauka waiū, hiki ke koho ʻia ke ʻano o ka mea BOPP/VMPET/S-PE.
No nā ʻeke ʻōpala kī, i mea e hōʻoia ai e pala nā lau kī, hoʻololi i ke kala a me ka ʻono, koho iā BOPP/AL/PE, BOPP/VMPET/PE, KPET/PE
Hiki i ke ʻano o ka mea ke pale aku i ka oxidation o ka protein, chlorophyll, catechin, a me ka wikamina C i loko o ke kī ʻōmaʻomaʻo.
ʻO nā mea i luna aʻe nei kekahi o nā mea hoʻopili meaʻai a Pack Mic i hōʻuluʻulu ai no ʻoe a pehea e hoʻohui ai i nā huahana like ʻole. Manaʻolana wau e kōkua ia iā ʻoe :)
