1. Māmā ke kaumaha, paʻakikī: ʻO ka crystallinity polyethylene density kiʻekiʻe (HDPE) he 80% ~ 90%, ʻo ka wahi palupalu he 125 ~ 135 ℃, kahi e alakaʻi aii ka paʻakikī, ʻoi aku ka maikaʻi o ka ikaika tensile ma mua o ka polyethylene haʻahaʻa haʻahaʻa; ʻO ka hapa he 0.941 ~ 0.960 ʻoi aku ka māmā ma mua owai. ʻO kēia ka mea e palupalu ai a e ahonui ai.

2. Palekana ʻawaʻawa a me ke kaiapuni: ʻAʻohe mea hoʻohui metala kaumaha, ʻaʻohe lepo a haumia bacteria paha; Maikaʻi ka mea HDPE no ka hana hou ʻana a me ka pale ʻana i ke kaiapuni.

3. Ola lawelawe lōʻihi: ʻEleʻele PE paipu kūpono uv kūpaʻa, kūpaʻa ʻelemakule, ola lawelawe lōʻihi o 50 mau makahiki.

4. Mea hana hoʻoheheʻe: Hiki ke hoʻoheheʻe ʻia ka paipu polyethylene i hoʻokahi me ka mea paipu. ʻAʻohe hiki ke liki,ka mālama ʻana i ka wai, ka hoʻemi ʻana i ke kumukūʻai a me ke kumukūʻai mālama.
