Degradable packaging eke, ka implication degradable, akā degradable packaging ua maheleia i "degradable" a me ka "piha degradable" elua ano.
Hana ʻia ka ʻeke plastik biodegradable i ka mauʻu mea kanu a me nā mea aloha i ke kino o ke kanaka a me ke kaiapuni, ʻokoʻa mai nā plastic synthetic ʻekolu, ma hope o ka ʻōpala, ma lalo o ka hana o ke kaiaola olaola, hiki ke decomposed iā ia iho, ʻaʻohe mea i ka poʻe a me ke kaiapuni. ʻaʻohe pōʻino, no ka ʻeke ʻōmaʻomaʻo.ʻO ka ʻeke plastic degradable kahi ʻano ʻeke kūʻai hoʻopau hiki ke hoʻohaʻahaʻa a maʻalahi hoʻi.
Hiki ke hoʻokaʻawale ʻia nā ʻeke plastik degradable i ʻelua ʻano mai ka ʻokoʻa o nā mea maka a me nā mea decomposition:
• Ua hana nui 'ia ka 'eke'ilika me ka plastic polyethylene, i hui 'ia me ka starch a me nā mea ho'ohehe'e olaola 'ē a'e, i 'ike 'ia ho'i he 'eke plastik biodegradable.ʻO kēia ʻano ʻeke plastik e decompose ma muli o ka hana a nā microorganisms.
• ʻO ka ʻano ʻē aʻe i hana nui ʻia me ka polyethylene plastic, i hui pū ʻia me ka pauka mineral e like me ka māmā desorption agent a me ka calcium carbonate, ʻo ia hoʻi i kapa ʻia he ʻeke plastik desorption māmā.ʻO kēia ʻano ʻeke plastik e haki ana ma lalo o ka hana a ka lā.
ʻO ka ʻeke hiki ke hoʻopau ʻia, ʻo ia hoʻi, ua hoʻohaʻahaʻa ʻia nā ʻeke plastik a pau i ka wai a me ka carbon dioxide.ʻO ke kumu nui o kēia mea hoʻoheheʻe piha ʻia e hana ʻia mai ka kulina, cassava a me nā mea ʻē aʻe i loko o ka lactic acid, i ʻike ʻia ʻo PLA.ʻO ka Poly Lactic Acid (PLA) kahi ʻano hou o ka substrate biological a me nā mea biodegradable hou.Hoʻomaʻamaʻa ʻia ka starch raw material no ka loaʻa ʻana o ka glucose, a laila hoʻomoʻi ʻia ka glucose a me kekahi mau kānana i mea e hana ai i ka waika lactic maʻemaʻe kiʻekiʻe, a laila hoʻohui ʻia ka PLA me kekahi kaumaha molekala e ke ʻano synthesis kemika.Loaʻa iā ia ka biodegradability maikaʻi.Ma hope o ka hoʻohana ʻana, hiki ke hoʻohaʻahaʻa loa ʻia e nā microorganism i ke ʻano ma lalo o nā kūlana kikoʻī, a ma hope e hoʻopuka ai i ka carbon dioxide a me ka wai.ʻAʻole ia e hoʻohaumia i ke kaiapuni, he mea maikaʻi loa ia i ka pale ʻana i ke kaiapuni a he mea pili i ke kaiapuni no nā limahana.
