1. Nā ʻokoʻa o ka noi.
Ka nui o ka hoʻohana ʻana oPepa PE: hoʻohana nui ʻia i ka ʻoihana kemika, mīkini, ʻoihana kemika, uila, lole, ʻōpala, meaʻai a me nā ʻoihana ʻē aʻe. Hoʻohana nui ʻia ia i ka lawe ʻana i ke kinoea, ka lako wai, ka hoʻokuʻu ʻana i ka wai ʻino, ka hoʻoulu ʻana i ka mahiʻai, ka lawe ʻana i nā ʻāpana paʻa maikaʻi i nā mines, a me ke kahua aila, ka ʻoihana kemika, ka leka uila a me ke kelepona, a pēlā aku, ʻoi aku hoʻi i ka lawe ʻana i ke kinoea.
ʻO ke ana hoʻohana o ka papa PP: no nā lako kūpaʻa waikawa a me ka alkaline, nā lako palekana kaiapuni, nā lako hoʻokuʻu wai ʻōpala a me nā lako hoʻokuʻu kinoea ʻōpala, hale kiaʻi holoi, lumi ʻole lepo, nā lako o ka hale hana semiconductor a me kāna mau ʻoihana pili, a me ka mea makemake ʻia no ka hana ʻana i ka pahu wai plastik. I loko o kēia wā, hoʻohana nui ʻia ka papa mānoanoa PP no ka papa hehi, ka papa punch, a pēlā aku.
2. Nā ʻokoʻa o nā ʻano.
He palupalu ka papa PE a he paʻakikī kekahi, a ʻoi aku ka maikaʻi o kona kūpaʻa i ka hopena a me ka hana cushioning, ʻoi aku ka maikaʻi o ka hana o ka papa i hoʻoheheʻe ʻia; He paʻakikī kiʻekiʻe ka papa PP, nā waiwai mechanical maikaʻi ʻole, haʻahaʻa ka paʻakikī a me ka pale hopena maikaʻi ʻole.
3. Nā ʻokoʻa o nā mea hana.
ʻO ka papa PP, i ʻike ʻia hoʻi he papa polypropylene (PP), he mea semi-crystalline. ʻOi aku ka paʻakikī ma mua o ka PE a he kiʻekiʻe ke kiko heheʻe. ʻO ka pepa PE kahi ʻano resin thermoplastic me ke kiʻekiʻe crystallinity a me ka non-polarity. ʻO ke ʻano o ka HDPE mua he keʻokeʻo waiū, a he translucent ia i kekahi ʻano ma ka ʻāpana lahilahi.
