1. No ka mea, aia ka pia i nā mea olaola e like me ka waiʻona, a ʻo ka plastic i loko o nā ʻōmole plastik no nā mea olaola, ua pōʻino kēia mau mea ola i ke kino o ke kanaka. Wahi a ke kumu o ka hoʻohālikelike kikoʻī, e hoʻoheheʻe kēia mau mea organik i ka pia. Hoʻokomo ʻia nā mea ʻawaʻawa ʻawaʻawa i loko o ke kino, no laila e pōʻino ai ke kino o ke kanaka, no laila ʻaʻole paʻa ka pia i loko o nā ʻōmole plastik.
2. Loaʻa i nā ʻōmole aniani ka maikaʻi o nā waiwai pale kinoea maikaʻi, ke ola mālama lōʻihi, ka ʻike maikaʻi, a me ka maʻalahi o ka hana hou ʻana, akā aia nā pilikia e like me ka hoʻohana ʻana i ka ikehu kiʻekiʻe i ka hana, cumbersomeness, a me ka pahū a me ka ʻeha.
I kēia mau lā, ua lilo ka hoʻomohala ʻana a me ka noiʻi ʻana o nā ʻōmole PET pale kiʻekiʻe me ka ʻeke pia e like me ka pahuhopu nui i lilo i wahi wela i ka ʻoihana, a ua holomua ka holomua ma hope o ka lōʻihi o ka hana noiʻi nui. Paʻa loa ka pia i ka māmā a me ka oxygen, a hiki i ka 120 lā ke ola. Pono ka oxygen permeability o ka hue pia ma mua o 1 × 10-6g i nā lā 120, a ʻo ka nalowale o CO2 ʻaʻole iʻoi aku ma mua o 5%.
ʻO kēia koi he 2 ~ 5 mau manawa o ka waiwai pale o ka'ōmole PET maʻemaʻe; Eia kekahi, hoʻohana kekahi mau breweries i ke ʻano pasteurization no ka pia, e koi ana i ka pale wela kiʻekiʻe a hiki i 298 ℃, ʻoiai ka ikaika, ka pale ʻana i ka wela, ka pale kinoea o ka ʻōmole PET maʻemaʻe ʻAʻole kūpono nā waiwai i nā koi o nā hue pia, no laila, ʻo nā kānaka. heihei i ka noiʻi a hoʻomohala i nā mea hou a me nā kaʻina hana hou no nā pale like ʻole a me nā hoʻonui.
I kēia manawa, ua oʻo ka ʻenehana o ka hoʻololi ʻana i nā ʻōmole aniani a me nā kini metala o ka pia me nā hue polyester, a ua hoʻomaka ke kaʻina hana kālepa. Wahi a ka wānana o "Modern Plastics" magazine, i ka 3 a hiki i ka 10 makahiki e hiki mai ana, e hoʻololi ʻia ka 1% a i ka 5% o ka pia o ka honua i ka pahu ʻōmole PET.
