1. Nā ʻokoʻa i ka noi.
E hoʻohana i ka pālākiō PE: hoʻohana nui ʻia i ka ʻoihana kemika, ka mīkini, ka ʻoihana kemika, ka mana uila, ka lole, ka ʻeke, ka meaʻai a me nā hana ʻē aʻe.Hoʻohana nui ʻia i ka lawe ʻana i ke kinoea, ka lako wai, ka wai, ka wai hoʻoheheʻe, ka hoʻoulu ʻana i ka ʻai, 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 ka alkali kū'ē mea lako, kaiapuni palekana lako, ka wai pau, pau kinoea hoʻokuʻu lako, holoi hale kiaʻi, maʻemaʻe lumi, semiconductor hale hana a me nā mea pili i ka ʻoihana, ʻo ia hoʻi ke koho mua no ka hana ʻana i ka pahu wai plastik, pp hoʻohana nui ʻia ka pā mānoanoa i ka pā kuʻi, ka pā 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 buffer, 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 waiwai.
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.
