1, ka ʻokoʻa o ka noi.
ʻO ka pālākiō hoʻohana oPepa PE: hoʻohana nui ʻia i ka ʻoihana kemika, ka mīkini, ka ʻoihana kemika, ka mana uila, ka lole, ka pahu, ka meaʻai a me nā ʻoihana ʻē aʻe. Hoʻohana nui ʻia ia i ka lawe ʻana i ke kinoea, ka hoʻolako wai, ka hoʻokuʻu ʻia ʻana o ka wai, ka irrigation mahiʻai, kaʻu kaʻa paʻa paʻa koʻikoʻi, ka ʻaila ʻaila, ka ʻoihana kemika, ka pou a me ke kelepona a me nā māla ʻē aʻe, ʻoi loa i ka lawe kinoea.

Ka laulā o ka hoʻohana ʻana opepa pp: ʻakika a me nā mea pale alkali, nā mea hoʻomalu kaiapuni, ka wai ʻino, nā lako hoʻokuʻu kinoea, ka hale kiaʻi holoi, lumi maʻemaʻe, nā mea hana no nā hale semiconductor a me nā ʻoihana e pili ana, a ʻo ia hoʻi ka mea i makemake ʻia no ka hana ʻana i nā pahu wai plastik, ma waena o nā pā mānoanoa PP hoʻohana nui ʻia.

2. Ka okoa o na ano.

Papa PEhe palupalu, he ʻano paʻakikī, ʻoi aku ka maikaʻi o ka hopena a me ka hana cushioning, a ʻoi aku ka maikaʻi o ka hana o ka papa i hoʻoheheʻe ʻia; He kiʻekiʻe ka paʻakikī o ka papa PP, nā waiwai mechanical maikaʻi ʻole, haʻahaʻa haʻahaʻa, a maikaʻi ʻole ka hopena a me ka cushioning.

3. ʻO ka ʻokoʻa o nā mea.

papa PP, ʻike ʻia ʻo polypropylene (PP), he mea semi-crystalline. ʻOi aku ka paʻakikī a ʻoi aku ka nui o ka heheʻe ma mua o ka PE. ʻO ka pepa PE he mea hoʻoheheʻe nui loa, non-polar thermoplastic resin. ʻO ka hiʻohiʻona o ka HDPE mua he keʻokeʻo waiū, a ʻo ka ʻāpana lahilahi he translucent i kekahi ʻano.
