He aha ka ʻokoʻa ma waena o nā ʻeke PP a me PE?

He mea maʻamau nā ʻeke palaki i ko kākou ola o kēlā me kēia lā, akā, ʻaʻole like nā ʻeke palaki a pau. ʻO ʻelua o nā ʻano ʻeke palaki kaulana loaPPnā ʻeke (Polypropylene) a me PENā ʻeke (Polyethylene). ʻO ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o kēia mau mea ʻelua e hiki ke kōkua i nā mea kūʻai aku a me nā ʻoihana e hana i nā koho maikaʻi aʻe. Ma kēia ʻatikala, e ʻeli mākou i nā ʻano, nā hoʻohana, a me nā pono o nā ʻeke PP a me PE, me ka nānā kūikawā ʻana i ke kumu he koho maikaʻi loa nā ʻeke PE no nā mākeke ma nā ʻāina i hoʻomohala ʻia e like me USA a me ʻEulopa.

Hoʻolauna i nā ʻeke PP (Polypropylene) a me nā ʻeke PE (Polyethylene)
Nā ʻeke PP (Polypropylene):

Mea Hana: ʻO ka Polypropylene kahi polymer thermoplastic i hoʻohana ʻia i nā ʻano hana like ʻole.
Nā ʻano: Ua kaulana nā ʻeke PP no ko lākou kiʻekiʻe o ka heheʻe ʻana, ka lōʻihi, a me ke kūʻē ʻana i nā kemika.
Nā Hoʻohana Maʻamau: Hoʻohana pinepine ʻia kēia mau ʻeke no ka hoʻopili ʻana i ka meaʻai, nā lole, a me nā waiwai kūʻai ʻē aʻe.

Nā ʻeke PE (Polyethylene):

Mea Hana: ʻO Polyethylene kekahi polymer thermoplastic i hoʻohana nui ʻia.

Nā ʻano: ʻOi aku ka palupalu o nā ʻeke PE a ʻoi aku ka maʻalahi ma mua o nā ʻeke PP, me ke kūpaʻa maikaʻi loa i ka makū a me nā kemika.
Nā Hoʻohana Maʻamau: Hoʻohana pinepine ʻia lākou no nā ʻeke meaʻai, nā ʻeke ʻōpala, a me nā kiʻiʻoniʻoni hoʻopili.
Ke hoʻohālikelike nei i nā ʻeke PP a me PE

Mea a me ke kūpaʻa
Nā ʻEke PP: ʻIke ʻia no ko lākou paʻakikī a me ke kiko heheʻe kiʻekiʻe, hiki i nā ʻeke PP ke kū i nā mahana kiʻekiʻe a ʻoi aku ka pale ʻana i ka ʻaʻahu a me ka haehae.
ʻEke PE: ʻOiai ʻaʻole paʻakikī e like me nā ʻeke PP, ʻoi aku ka maʻalahi o nā ʻeke PE a ʻaʻole hiki ke nahā. Loaʻa iā lākou ke kūpaʻa maikaʻi i ka makū a me nā kemika.
Nā Hoʻohana a me nā Noi
ʻEke PP: Kūpono no nā noi e pono ai ka ikaika kiʻekiʻe a me ke kūpaʻa, e like me ka hoʻopili kaumaha a me nā hoʻohana ʻoihana.
Nā ʻEke PE: ʻOi aku ka kūpono no nā noi o kēlā me kēia lā e like me nā ʻeke kūʻai, nā ʻeke mālama meaʻai, a me nā ʻili ʻōpala.
Nā Pōmaikaʻi a me nā Pōʻino
Nā ʻeke PP:
Nā Pōmaikaʻi: Ikaika kiʻekiʻe, kūpaʻa, a me ke kūpaʻa ʻana i nā mahana kiʻekiʻe a me nā kemika.
Nā Pōʻino: ʻAʻole maʻalahi ka loli, ʻoi aku ke kumukūʻai, a ʻaʻole kūpono i ke kūpaʻa ʻana i ka makū.
Nā ʻeke PE:
Nā Pōmaikaʻi: Maʻalahi, kūpono ke kumukūʻai, kūpaʻa maikaʻi loa i ka makū, a hiki ke hana hou ʻia ma nā wahi he nui.
Nā Pōʻino: Haʻahaʻa ka pae hoʻoheheʻe a emi ke kūpaʻa i ka ʻaʻahu a me ka haehae ke hoʻohālikelike ʻia me nā ʻeke PP.

Nā Hoʻohana Kūpono: Nā ʻEke PP vs. PE
Nā Hale Kūʻai Meaʻai: ʻO nā ʻeke PE ke koho makemake ʻia ma muli o ko lākou palupalu a me ke kūpaʻa i ka makū, e kūpono ai lākou no ka lawe ʻana i nā mea palaho.
Nā Hale Kūʻai Lole: Hoʻohana pinepine ʻia nā ʻeke PP no ko lākou kūpaʻa a me ka hiki ke lawelawe i nā mea kaumaha me ka ʻole o ka haehae ʻana.
Pāʻū Meaʻai: Hoʻohana pinepine ʻia nā ʻeke PE no ka pāʻū meaʻai no ka mea hāʻawi lākou i kahi pale makū maikaʻi a palekana no ka hoʻopili ʻana i ka meaʻai.
Koi o ka Mākeke ma nā ʻĀina i Hoʻomohala ʻia
Ma nā ʻāina i hoʻomohala ʻia e like me ʻAmelika Hui Pū ʻIa a me ʻEulopa, nui ka makemake no nā ʻeke palaki, ʻoiai nā ʻeke PE, ma muli o ko lākou hiki ke hoʻohana ʻia a me ke kumukūʻai kūpono. Hoʻoikaika nā mea kūʻai aku ma kēia mau wahi i ka maʻalahi a me ke kūpaʻa o ke kaiapuni, e lilo ai nā ʻeke PE i koho kaulana.
