Ma waho aʻe o ka PVC, hana pū mākou i nā kāleka i loko o ka polycarbonate (PC) a me ka Polyethylene Terephthalate Glycol (PETG). ʻO kēia mau mea palaki ʻelua e hana i nā kāleka i kūpaʻa loa i ka wela.

No laila, he aha ka PETG a no ke aha ʻoe e noʻonoʻo ai no kāu mau kāleka plastik? ʻO ka mea hoihoi, hana ʻia ʻo PETG mai ka polyester (e pololei, thermoplastic copolyester) ʻaʻole PVC, a he 100 pakeneka hiki ke hana hou ʻia A biodegradable. Eia naʻe, hana mau ia e like me PVC, no laila he paʻakikī loa ia a kūʻē i ka hopena. He maʻalahi ka paʻi ʻana me PETG a nani ke ʻano o nā hoʻolālā! E nānā i ke ʻano maikaʻi o nā hoʻolālā ma PETG.

No laila, kūpono nā kāleka PC a me PETG no nā ʻāina wela, no ka laʻana ʻo United Arab Emirates a i ʻole ʻAmelika Hema, kahi e hiki ai i ka mahana i ke kauwela ke piʻi i 40 degere Celsius, a i ʻole 65 degere Celsius i loko o nā kaʻa. Hoʻomaka ka PVC e heheʻe ma 60 degere.

He kūpaʻa ko mākou kāleka PC a me PETG i ka wela a hiki i 120 degere Celsius. ʻO ia hoʻi, i kekahi mau kūlana ʻino loa, hiki ke waiho ʻia kahi kāleka ID kūhelu i loko o ke kaʻa i ka wā ʻaina awakea me ka hopohopo ʻole, a ʻaʻole pono e hoʻokahe ʻia kahi mīkini kāleka ma kahi kahua kaʻa ma Toronto a hiki i ke ahiahi. He paʻakikī loa kēia mau kāleka, no laila hiki ke hoʻohana ʻia a hiki i ka ʻumi makahiki.

E hana mākou i ka mea maikaʻi loa e hoʻomau i ka hoʻokō ʻana i nā pono o kā mākou mea kūʻai aku ma o ka hoʻomau ʻana i ka hoʻomohala ʻana, hana ʻana a me ka hoʻolako ʻana i nā huahana hou a kiʻekiʻe hoʻi.
