I kēia mau lā, he paʻakikī ka manaʻoʻiʻo i kēia, akā i kēia manawa, ua nui ka waiwai o nāʻeke'ilika a me ka lakaʻole, aʻaʻole kekahi o nāʻano hōʻailona hiki ke kūʻaiʻia. Ua loli ka manawa maikaʻi no ka maikaʻi a kokoke i kēlā me kēia lumi kuke e loaʻa iāʻoe kahi'ōwili polyethylene a polyvinyl chloride film. Ua mahalo nā wahine wahine i nāʻano maikaʻi a pau o kēia mea a hoʻohanaʻia me ka holomua maikaʻi no ka hoʻolakoʻana i nā huahana, me ka hoʻopiliʻana i nā papa'āina a me ka kukeʻai. Aʻo nā mea pāʻani maikaʻi loa e hiki iāʻoe ke aʻo mai ka mea kākau.
Hōʻike kiʻi no nā meaʻai
ʻO ka mea mua, eʻike kākou i ka heroine o kā kākou mea e pili nei. Hiki i ka'enehe meaʻai ke hana a polyethylene a polyvinyl chloride (PVC). Aʻoiai he mea paʻakikī ia i kahi kanaka moe eʻike i keʻano o kekahi i kekahi ma kaʻike muaʻana, aia kekahi mauʻokoʻa ma nāʻano. ʻO ka mea nui ka hoʻopihaʻia o ke kinoea a me ka ikaika o ka wai o polyethylene film ma keʻano likeʻole i kona pili "PVC". I kēiaʻano, hiki ke hoʻohanaʻia ke kiʻi i hanaʻia i nā papaʻi lahilahi o ka polyethylene, no ka mea maʻamau wale nō, no ka hōʻailonaʻana i nāʻala , nā huaʻai, nā hua, ka berena. ʻO nā huahana i lalo o kēlā pū e hōʻikeʻoleʻia i nā hopena luku o ka'ōlohelohe a mālama piha i nā mea waiwai i loko o ke ola o ka huahana. E hoʻopau ka ho'āʻoʻana e launa i kahi mea i loko o kahi kiʻi paʻi paopao i kahi fiasco holoʻokoʻa: e hoʻololi a haʻalele i kona mau mea mālama. ʻAʻole ke ala maikaʻi loa, hiki i ka polyethylene ka hopena i kahi hāmole lōʻihi o ka mahana - ma ka paʻukū , e lilo koke ia i ao a lilo i mea kūpilikiʻi. Akā, e paʻi ka PVC kiʻi i nā meaʻai wela a me ka maloʻo, aʻo ka pele ma lalo o ia mea,ʻaʻole e nalowale kona nani aʻaʻole e liʻiliʻi. Eia hou, ua piliʻole i nā momona a me nā waikawa, aʻo ia ka mea hou e lilo ai i mea palekana no ka hōʻaikaʻana i nā kīʻahaʻaila. Eia hou, hiki i ka hiki ke pale i nā mea wela kūpono e hoʻohana ai i kahi pēlāʻoniʻoni ma loko o ka umu welawewe, e like me ka hoʻoukaʻana i nā kīʻaha me ka weheʻoleʻana i ka hōʻailona. Eia kekahi, ua like ka nui o nā kiʻiʻoniʻoni likeʻole -ʻo kēia mau mea i loaʻa ka ikaika e hoʻoluliluli iʻekolu manawa i ka lōʻihi o ka lōʻihi a pili pono i kekahi mahele. ʻO kēia mau mea eʻae ai iāʻoe e kokoke koke e hoʻolako i nā huahana o kēlā me kēiaʻano a me ka nui, me ka hoʻohanaʻoleʻana i nā pākuʻi a me nā laikiniʻekolu. Hiki iā ia ke hana me ke kōkua o nā mīkini loiloi kūikawā, a ma ka hoʻoukaʻana i ka'ōwili pepa ma ka lima.
E hōʻemi i ka meaʻai kiʻi
ʻO kekahi wahi kūikawā i waena o nā mea hoʻomoʻa meaʻai hōʻemi i ke kiʻi. ʻO kona hiʻohiʻona hiʻohiʻona ka hiki i ka'elikeʻana ma lalo o ka hopena o ka wela a lawe i keʻano o ka mea i hoʻokomoʻia. Ua loaʻa iā ia ka noi nui loa ma kahi o ke kālepaʻana, kahi i hoʻolakoʻia ai nāʻano meaʻai likeʻole i loko o kahi kiʻiʻoniʻoni. I kēia hihia, hiki i ka kiʻi paʻi ke kūpono i ka mālie, a no laila ua loaʻa i ka mea kūʻai ke kūpono i nā mea a pau
ʻO ka meaʻeleʻele o ka meaʻai
Hiki ke loaʻa ka polyethylene meaʻai maʻamau i kaʻeleʻele o 6, 7.5, aiʻole 8 mau micron. No ka pāʻani PVC no kaʻai, hiki ke kohoʻia kēia koho i 8, 9, 10, 12 aiʻole 14 mau micron. Ke kohoʻoe i ka mānoanoa, ponoʻoe e nānā i kaʻano o nā huahana e hoʻopiliʻia. No laila, no ka hoʻopiliʻana i nā hua, nā hua, nā halola a me nā huaʻai, ponoʻia kahi pVC kiʻi me ka mānoanoa o 9 micron. A no nā meaʻai, iʻa a me nā huaʻai hoʻopauʻole, ponoʻoe e kiʻi i kahi kiʻiʻoniʻoni me 12mm mau micron.
