1. Nā ʻokoʻa o ka noi.
ʻO ka unahi hoʻohana o ka papa PE: hoʻohana nui ʻia i ka ʻoihana kemika, mīkini, ʻoihana kemika, mana uila, lole, ʻōpala, meaʻai a me nā ʻoihana ʻē aʻe. Hoʻohana nui ʻia i ka lawe ʻana i ke kinoea, ka lako wai, ka wai ʻino, ka hoʻoulu ʻana i ka mahiʻai, ka lawe ʻana i nā ʻāpana paʻa maikaʻi, a me ke kahua aila, ka ʻoihana kemika a me ka leka uila a me ke kelepona, ʻoi aku hoʻi i ka lawe ʻana i ke kinoea.

ʻO ka unahi hoʻohana ʻana o ka papa Pp: nā lako hana kūpaʻa waikawa a me ka alkali, nā lako palekana kaiapuni, ka wai ʻōpala, nā lako hoʻokuʻu kinoea ʻōpala, ka hale holoi, ka lumi maʻemaʻe, ka hale hana semiconductor a me nā lako ʻoihana e pili ana, ʻo ia hoʻi ke koho mua no ka hana ʻana o ka pahu wai plastik, hoʻohana nui ʻia ka papa pp mānoanoa i ka papa punching, ka papa punching a pēlā aku.
2. Nā ʻokoʻa o nā ʻano.
He palupalu ka papa PE, he paʻakikī kekahi, ʻoi aku ka maikaʻi o ke kūpaʻa a me ka hana buffer, ʻoi aku ka maikaʻi o ka hana o ka papa i hoʻoheheʻe ʻia; paʻakikī kiʻekiʻe ka papa PP, ʻaʻole maikaʻi nā waiwai mechanical, haʻahaʻa ka paʻakikī, a maikaʻi ʻole ka buffer hopena.
3. Nā ʻokoʻa o nā mea hana.
ʻO ka papa PP, i ʻike ʻia hoʻi ʻo ka papa polypropylene (PP), he mea semi-crystalline. ʻOi aku ka paʻakikī ma mua o ka PE a he kiʻekiʻe kona kiko heheʻe. ʻO ka pepa PE kahi crystallinity kiʻekiʻe, non-polar thermoplastic resin. ʻO ke ʻano o ka HDPE mua he keʻokeʻo waiū, me kahi kekelē o ka translucency ma ka ʻāpana lahilahi.
