He aha ka ʻeke kraft me ka PLA i uhi ʻia

ʻO ka ʻeke kraft i uhi ʻia ʻo PLA he ʻenehana hou o ka pōʻai, ʻo ia ka hoʻohaʻahaʻa ola kino, a me ka decomposition i loko o nā ʻāpana kūlohelohe. No laila he aha ke ʻano o ia mea? Hoʻohana mākou i ke kuanaʻike biological e wehewehe pehea.

ʻO ka pepa i uhi ʻia ʻo PLA (biodegradable coated paper) ponoʻī he huahana pale kaiapuni holoʻokoʻa. ʻO ka polylactic acid (PLA) he ʻano mea hou o ka biodegradable hoʻomalu kaiapuni, i hana ʻia mai nā mea starch i manaʻo ʻia e nā kumu mea kanu hou (e like me ke kulina). Hoʻomaʻamaʻa ʻia ka starch raw material no ka loaʻa ʻana o ka glucose, a laila hoʻoheheʻe ʻia ka glucose a me kekahi kānana e hana ai i ka waikawa lactic maʻemaʻe kiʻekiʻe, a laila hoʻohui ʻia ka polylactic acid me kahi kaumaha molecular e ka synthesis kemika. Loaʻa iā ia nā mea thermoplastic biodegradable a me ka compostable, a ʻo nā mea kanu ka mea kumu nui; Ma hope o ka unuhi ʻana, ka fermentation a me ka polymerization, hiki ke hoʻohaʻahaʻa ʻia ka 100% biodegradable piha i carbon dioxide a me ka wai i koi ʻia no ka ulu ʻana o nā mea kanu e nā microorganism ma ke ʻano i loko o kahi kaiapuni. He biodegradability maikaʻi a ʻaʻole hoʻohaumia i ke kaiapuni, he mea maikaʻi loa ia i ka pale ʻana i ke kaiapuni. He mea maʻamau ka mālama kaiapuni ma waho. Ke hoʻohālikelike ʻia me nā huahana pepa i uhi ʻia PE maʻamau, hiki ke hana hou ʻia nā huahana pepa i uhi ʻia ma hope o ka hoʻohana ʻana. ʻO nā ʻano hana hoʻopōmaikaʻi kūikawā a me nā ʻano like ʻole o nā kumuwaiwai hou e hoʻemi nui i ke kaumaha o nā kumuwaiwai kūlohelohe a me ke kaiapuni, a hoʻokō i nā pae hoʻohālikelike ʻōmaʻomaʻo pau ʻole.

Hiki i ka ʻeke makemake ke hoʻohana i ka ʻeke kraft me ka hoʻolālā ʻoki maʻalahi, ka mānoanoa tassel, nā kaʻina hana e hoʻopaʻa ʻia, kūpono i kāu mea kūʻai aku e mālama, ʻike maikaʻi, a me nā koi palekana. Hiki i ka ʻeke pepa kraft ke ʻeke kūʻokoʻa kūʻokoʻa / ʻeke kope kūʻokoʻa, hiki iā ia ke kū pono i nā ʻeke kraft hiki ke hōʻike kūʻokoʻa ma ka papa me ka ʻole carton. ʻAʻole i koho ʻia. No laila ke hele mai nei ke kumukūʻai. Ma waho aʻe o nā ʻeke kū i luna, hiki ke lilo i ʻeke kope me ka valve. Hoʻohana nui ʻia lākou a pau ma lalo o nā ʻoihana: Kofe, kī, Snack, meaʻai holoholona a me nā kuki.
