1. Nā ʻokoʻa i ka noi.
Ka hoʻohana ʻana o ka pā pā PE: hoʻohana nui ʻia i ka ʻoihana kemika, nā mīkini, nā ʻoihana kemika, ka mana uila, nā lole, ka ʻeke, nā meaʻai a me nā hana ʻē aʻe. Hoʻohana nui ʻia i ka lawe ʻana i ke kinoea, ka lako wai, ka ʻili wai, ka irrigation mahiʻai, ka hoʻohana ʻana i ka ʻaila paʻa paʻa, a me ka māla aila, ʻoihana kemika a me ka pou a me ke kelepona, ʻoi aku ka nui o ka lawe ʻana i ke kinoea.

Pp pā hoʻohana pālākiō: acid a me alkali pale lako, kaiapuni pale lako, ka wai pau, pau kinoea hoʻokuʻu lako, holoi hale kiaʻi, maʻemaʻe lumi, semiconductor hale hana a me nā mea e pili ana i nā ʻoihana, ʻo ia hoʻi ke koho mua no ka hana ʻana i ka pahu wai plastik, pp mānoanoa pā i hoʻohana nui ʻia i ka punching plate, punching plate a pēlā aku.
2. Nā ʻokoʻa o nā ʻano.
ʻOi aku ka palupalu o ka pā PE, ʻoi aku ka paʻakikī, ʻoi aku ka maikaʻi o ka pale ʻana a me ka hana pale, ʻoi aku ka maikaʻi o ka hana o ka pā i hoʻoheheʻe ʻia; ʻO ka papa PP ka paʻakikī kiʻekiʻe, ʻaʻole maikaʻi nā waiwai mechanical, haʻahaʻa haʻahaʻa, haʻahaʻa hopena maikaʻi ʻole.
3. Nāʻokoʻa i nā mea.
ʻO ka papa PP, i kapa ʻia ʻo polypropylene (PP) papa, he mea semi-crystalline. ʻOi aku ka paʻakikī ma mua o ka PE a ʻoi aku ka nui o ka heheʻe. ʻO ka pepa PE he crystallinity kiʻekiʻe, non-polar thermoplastic resin. ʻO ka hiʻohiʻona o ka HDPE mua he keʻokeʻo waiū, me kahi pae o ka translucency i ka ʻāpana lahilahi.
