I nā makahiki i hala iho nei, ua hoʻonui ʻia ka manaʻo nui o ka honua i ka hoʻomau i ka ʻoihana paʻi. ʻO nā kiʻiʻoniʻoni plastik kuʻuna, e like me PET (Polyethylene Terephthalate), ua lōʻihi ka mana ma muli o ko lākou lōʻihi a me ka versatility. Eia nō naʻe, ʻo nā hopohopo e pili ana i kā lākou hopena kaiapuni ua hoʻoulu i ka hoihoi ikiʻiʻoniʻoni biodegradablenā mea ʻē aʻe e like me Cellophane a me PLA (Polylactic Acid). Hōʻike kēia ʻatikala i kahi hoʻohālikelike piha ma waena o nā kiʻiʻoniʻoni biodegradable a me nā kiʻiʻoniʻoni PET kuʻuna, e kālele ana i kā lākou haku mele ʻana, ka hopena o ke kaiapuni, ka hana, a me nā kumukūʻai.
Ka Hui Mea a me ke Kumu
Kiʻiʻoniʻoni PET kuʻuna
ʻO PET kahi resin plastic synthetic i hana ʻia ma o ka polymerization o ka ethylene glycol a me terephthalic acid, nā mea ʻelua i loaʻa mai ka ʻaila ʻaila. Ma ke ʻano he mea hilinaʻi piha i nā wahie fossil hiki ʻole ke hoʻololi hou ʻia, ʻoi aku ka ikaika o kāna hana ʻana i ka ikehu a hāʻawi nui i nā hoʻokuʻu kalapona honua.

✅Kiʻiʻoniʻoni Cellophane:Kiʻiʻoniʻoni cellophanehe kiʻiʻoniʻoni biopolymer i hana ʻia mai ka cellulose i hoʻōla hou ʻia, i kumu mua ʻia mai ka pulp lāʻau. Hana ʻia kēia mea me ka hoʻohana ʻana i nā kumuwaiwai hou e like me ka lāʻau a i ʻole ka ʻohe, e kōkua ana i kāna ʻike paʻa. ʻO ke kaʻina hana e hoʻoheheʻe i ka cellulose i loko o kahi hopena alkali a me ka carbon disulfide e hana i kahi hopena viscose. Hoʻokuʻu ʻia kēia hoʻonā ma kahi ʻāpana lahilahi a hana hou ʻia i kahi kiʻiʻoniʻoni. ʻOiai ʻo kēia kaʻina hana maʻalahi ka ikehu a pili i ka hoʻohana ʻana i nā kemika weliweli, ke kūkulu ʻia nei nā kaʻina hana hou e hōʻemi i ka hopena o ke kaiapuni a hoʻomaikaʻi i ka hoʻomau holoʻokoʻa o ka hana cellophane.

✅Kiʻiʻoniʻoni PLA:PLA kiʻiʻoniʻoni(Polylactic Acid) he biopolymer thermoplastic i loaʻa mai ka waika lactic, i loaʻa mai nā kumuwaiwai hou e like me ka starch kulina a i ʻole ke kō. Ua ʻike ʻia kēia mea he mea hoʻololi mau i nā plastic plastic ma muli o kona hilinaʻi ʻana i nā meaʻai mahiʻai ma mua o nā wahie fossil. ʻO ka hana ʻana o PLA e pili ana i ka fermentation o nā mea kanu sugars e hana i ka lactic acid, a laila polymerized e hana i ka biopolymer. ʻOi aku ka liʻiliʻi o kēia kaʻina hana i ka wahie mōʻalihaku i hoʻohālikelike ʻia i ka hana ʻana i nā plastics i hoʻokumu ʻia i ka aila, e hana ana i ka PLA i kahi koho ʻoi aku ka maikaʻi o ke kaiapuni.
Ka hopena o ke kaiapuni
Hiki i ka biodegradability
-
Cellophane: Hiki ke hoʻoheheʻe ʻia i loko o ka hale a i ʻole ka ʻoihana, e hoʻohaʻahaʻa ʻia i loko o 30-90 mau lā.
-
PLA: Hiki ke hoʻoheheʻe ʻia ma lalo o nā kūlana compost ʻoihana (≥58°C a me ka haʻahaʻa kiʻekiʻe), maʻamau i loko o 12-24 pule. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ke kai a i ʻole ka honua kūlohelohe.
-
PET: ʻAʻole hiki ke biodegradable. Hiki ke hoʻomau i ke kaiapuni no 400-500 mau makahiki, e hāʻawi ana i ka pollution plastic lōʻihi.
Kaha Kaona
- Cellophane: Mai ka 2.5 a i ka 3.5 kg CO₂ no ke kilo kiʻiʻoniʻoni, e pili ana i ke ʻano hana.
- PLA: Hoʻopuka ma kahi o 1.3 a 1.8 kg CO₂ no ke kilo kiʻiʻoniʻoni, ʻoi aku ka haʻahaʻa ma mua o nā plastik kahiko.
- PET: Mai ka 2.8 a hiki i ka 4.0 kg CO₂ no ke kilo kiʻiʻoniʻoni ma muli o ka hoʻohana ʻana i ka wahie fossil a me ka hoʻohana ʻana i ka ikehu kiʻekiʻe.
Hana hou
- Cellophane: Hiki ke hana hou ia, aka, ua hoopili pinepine ia ma muli o kona biodegradability.
- PLA: Hiki ke hana hou ʻia i loko o nā hale hana kūikawā, ʻoiai ua kaupalena ʻia nā ʻōnaehana honua maoli. Hoʻopau ka hapa nui o ka PLA i nā ʻōpala a i ʻole ka hoʻopau ʻana.
- PET: Hiki ke hana hou ʻia a ʻae ʻia i ka hapa nui o nā papahana kaona. Eia nō naʻe, haʻahaʻa mau ka nui o ka hana hou ʻana o ka honua (~ 20–30%), me 26% wale nō o nā hue PET i hana hou ʻia ma US (2022).

Hiki a me ka ikaika
Cellophane
Hōʻike ʻo Cellophane i ka maʻalahi a me ke kūpaʻa haʻahaʻa haʻahaʻa, kūpono ia no nā noi hoʻopili e koi ana i kahi kaulike maʻalahi ma waena o ke kūpaʻa a me ka maʻalahi o ka wehe. ʻO kona ikaika tensile maʻamau mai100–150 MPa, e pili ana i ke kaʻina hana a i uhi ʻia no ka hoʻomaikaʻi ʻana i nā waiwai pale. ʻOiai ʻaʻole ikaika e like me ka PET, hiki i ka cellophane ke kulou me ka ʻole o ka haki ʻana a me kona ʻano kūlohelohe he mea kūpono ia no ke kāʻei ʻana i nā mea māmā a me nā mea maʻalahi e like me nā mea i kālua ʻia a me nā kukui.
PLA (Polylactic Acid)
Hāʻawi ka PLA i ka ikaika mechanical kūpono, me ka ikaika tensile maʻamau ma waena50–70 MPa, ka mea e hoʻohālikelike ʻia me kekahi o nā plastik maʻamau. Eia naʻe, konapalupaluʻO kahi drawback koʻikoʻi—ma lalo o ke koʻikoʻi a i ʻole nā haʻahaʻa haʻahaʻa, hiki i ka PLA ke haki a ʻāhaʻi paha, ʻaʻole kūpono ia no nā noi e koi ana i ke kūpaʻa hopena kiʻekiʻe. Hiki i nā mea hoʻohui a me ka hui pū ʻana me nā polymers ʻē aʻe ke hoʻomaikaʻi i ka paʻakikī o PLA, akā pili paha kēia i kona compostability.
PET (Polyethylene Terephthalate)
Manaʻo nui ʻia ʻo PET no kāna mau waiwai mechanical maikaʻi. Hāʻawi ia i ka ikaika tensile kiʻekiʻe-mai ka50 a 150 MPa, ma muli o nā kumu e like me ka māka, ka mānoanoa, a me nā ʻano hana (e laʻa, biaxial orientation). ʻO ka hui pū ʻana o ka PET o ka maʻalahi, ka lōʻihi, a me ke kūʻē ʻana i ka puncture a me ka waimaka e lilo ia i mea makemake no nā ʻōmole inu, nā pā, a me nā ʻeke hana kiʻekiʻe. Hana maikaʻi ʻo ia ma kahi ākea ākea ākea, mālama pono i ka pono ma lalo o ke kaumaha a i ka wā o ka lawe ʻana.

Na Waiwai Keakea
Cellophane
Ua loaʻa iā Cellophaneʻano pale ʻano haʻahaʻakū'ē i nā kinoea a me ka makū. Konaka nui o ka lawe ʻana o ka oxygen (OTR)mea maʻamau mai500 a 1200 cm³/m²/lā, i kūpono no nā huahana pōkole e like me nā huahana hou a i ʻole nā mea i kālua ʻia. Ke uhi ʻia (e laʻa me PVDC a i ʻole nitrocellulose), ʻoi aku ka maikaʻi o kāna hana pale. ʻOiai ʻoi aku ka maʻalahi ma mua o ka PET a i ʻole PLA, hiki i ka hanu kūlohelohe o cellophane ke lilo i mea maikaʻi no nā huahana e koi ana i kahi hoʻololi wai.
PLA
Hāʻawi nā kiʻiʻoniʻoni PLAʻoi aku ka maikaʻi o ka pale ʻana ma mua o ka cellophaneakā ua loaʻakiʻekiʻe o ka oxygen permeabilityma mua o PET. Hāʻule ka OTR ma waena100–200 cm³/m²/lā, ma muli o ka mānoanoa film a me ka crystallinity. ʻOiai ʻaʻole maikaʻi no ka hoʻohana ʻana i ka oxygen-sensitive (e like me nā mea inu kalapona), hana maikaʻi ʻo PLA no ka hoʻopili ʻana i nā huaʻai hou, nā mea kanu, a me nā meaʻai maloʻo. Ke kūkulu ʻia nei nā papa hana PLA i hoʻonui ʻia i ka pale e hoʻomaikaʻi i ka hana ma nā noi koi.
PET
Hāʻawi ʻo PETʻoi aku ka maikaʻi o nā mea palema luna o ka papa. Me ka OTR e like me ka haʻahaʻa1–15 cm³/m²/lā, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka oxygen a me ka makū, e hoʻolilo iā ia i mea kūpono no ka ʻeke meaʻai a me ka mea inu kahi e pono ai ke ola lōʻihi. ʻO ka hiki ke pale o PET ke kōkua i ka mālama ʻana i ka ʻono o ka huahana, carbonation, a me ka hou, ʻo ia ke kumu e lanakila ai ka ʻāpana inu ʻeke.

ʻO nā mea ʻekolu a pau—Cellophane, PLA, a me PET—hāʻawimaikaʻi o ka ʻike maka, e hana ana ia lakou i kupono no ka hoopuka ana i na huahana kahihōʻike makamea nui.

Cellophanehe hiʻohiʻona ʻōlinolino a me ke ʻano kūlohelohe, hoʻonui pinepine i ka ʻike o nā mea hana a i ʻole nā huahana eco-friendly.

PETʻO ia ka ʻoihana ʻoihana no ka mālamalama, ʻoi aku ka nui o nā noi e like me nā hue wai a me nā ipu meaʻai maʻemaʻe, kahi e pono ai ka ʻike kiʻekiʻe e hōʻike i ka maikaʻi o ka huahana.

Hoʻopili Meaʻai
Cellophane: Hoʻohana mau ʻia no nā hua hou, nā mea ʻai palaoa no nā makana, e like meʻeke makana cellophane, a me nā mea ʻono ma muli o ka hanu a me ka biodegradability.
PLA: Hoʻohana nui ʻia i loko o nā ipu clamshell, hana i nā kiʻiʻoniʻoni, a me ka paʻi waiu ma muli o kona māmā a me ka compostability, e like mePLA pili kiʻiʻoniʻoni.
PET: ʻO ke kūlana o ka ʻoihana no nā ʻōmole inu, nā pā meaʻai maloʻo, a me nā ipu like ʻole, mahalo ʻia no kona ikaika a me ka hana pale.

Hoohana Hana Hana
Cellophane: Loaʻa i loko o nā noi kūikawā e like me ka uhi ʻana i ka cigarette, ka ʻōpala blister pharmaceutical, a me ka uhi makana.
PLA: Hoʻohana ʻia i loko o ka ʻeke lapaʻau, nā kiʻiʻoniʻoni mahiʻai, a me ka hoʻonui ʻana i nā filament paʻi 3D.
PET: Hoʻohana nui ʻia i loko o ka hoʻopili ʻana i nā mea kūʻai aku, nā ʻāpana kaʻa, a me nā mea uila ma muli o kona ikaika a me ke kūpaʻa kemika.
ʻO ke koho ʻana ma waena o nā koho biodegradable e like me Cellophane a me PLA a i ʻole nā kiʻi ʻoniʻoni PET kuʻuna e pili ana i nā kumu he nui e pili ana i nā mea nui o ke kaiapuni, nā pono hana, a me nā kaohi kālā. ʻOiai ʻo PET ka mea nui ma muli o ke kumu kūʻai haʻahaʻa a me nā waiwai maikaʻi loa, ʻo ke kaumaha o ke kaiapuni a me ka manaʻo o nā mea kūʻai aku ke neʻe nei i ka neʻe ʻana i nā kiʻiʻoniʻoni biodegradable. Hāʻawi ʻo Cellophane a me PLA i nā pono kaiaola koʻikoʻi a hiki ke hoʻonui i ke kiʻi brand, ʻoi aku hoʻi i nā mākeke eco-conscious. No nā ʻoihana e ʻimi nei e noho ma mua o nā ʻano hoʻomau, ʻo ka hoʻopukapuka kālā ʻana i kēia mau mea ʻē aʻe hiki ke lilo i kuleana a me ka hoʻolālā.
