Hoʻopiliʻia nā paipu Hopesun Polyethylene (РЕ) mai ka resin polyethylene kiʻekiʻe, a ua hoʻonohonoho ponoʻia ke kaʻina hana e like me nā kūlana pili GB / T. ʻAʻole i loko o ka huahana nā mea hoʻohui metala koʻikoʻi, ʻaʻole i paʻa, ʻaʻole hoʻohua i ka bacteria, ʻaʻole ia e hoʻohaumia i ka lua o ka mea hoʻouna, a he paʻa kemika maikaʻi.
ʻO ka paipu PE he pale wela maikaʻi a me ke anu anuanu, kiʻekiʻe rigidity a me ka paʻakikī, maikaʻi ke kino a me ka mechanical waiwai, ka hopena o ka hopena, ke kūpaʻa haʻalulu ikaika, ka maʻalahi a me ka hoʻololi ʻana i ka hana, a hoʻololi i ka nui o nā loli kaiapuni. He mea maʻalahi ke kaʻina hana wili paipu РЕ, a ʻo ka ʻenehana kuʻi ʻana o ka makua e hōʻoia i ka ikaika o ka interface kiʻekiʻe, no laila ua maʻalahi ke kūkulu ʻana a ua haʻahaʻa ke kumukūʻai o ka papahana holoʻokoʻa.
ʻO ka paia o loko o ka paipu РЕ a me nā hiʻohiʻona non-adhesive o ka mea ponoʻī e hoʻoholo ai i ka hiki ke kiʻekiʻe o ka lawe ʻana i ka huahana, no laila ua emi ka hoʻohana ʻana i ka ikehu.
