ʻO ka maʻamau, hana ʻia nā ʻeke ʻōpala no nā napkin home i ka polyethylene haʻahaʻa (LDPE) a i ʻole copolymer polypropylene (CPP), e hāʻawi ana iā lākou i kahi ʻano palupalu a matte me ke kūpaʻa i ka makū a me ke kūpaʻa i ka haehae e pale i nā napkin mai ka makū.

Hoʻohana ʻia ka māka hoʻololi kala laser UV ma ka papa waho, e hoʻololi ana i ke ʻano molekala o ka uhi e hana i nā māka lā hana maopopo. Hōʻoia kēia ʻano hana ʻole-hoʻopau i nā māka kūpaʻa i ke komo ʻana, pale i ka mae ʻana e mau ana ka heluhelu ʻana i ka hala ʻana o ka manawa.

Hoʻohana ka māka laser UV ma ka uhi PET waho o nā ʻeke hoʻopili PET/AL/PE i nā kukuna laser ikehu kiʻekiʻe e hoʻoulu i nā hopena photochemical a me nā hopena wela iki. Ke hoʻopili ʻia i ka uhi keʻokeʻo, hoʻololi ka laser i ke ʻano molekala, e hoʻohuli ana i ka ʻili hina ma kahi o ka ablating wale ʻana i ka papa.

Hoʻopaʻa kēia kumumanaʻo hoʻololi kala i nā māka maopopo a paʻa, i hoʻohana pinepine ʻia no ka paʻi ʻana i nā lā hana a me nā helu puʻupuʻu. Noho paʻa nā māka i ke komo ʻana a me ka pale ʻana i ka mae ʻana, e noho maʻalahi ana ke heluhelu ʻia ʻoiai ma lalo o ka hoʻohana lōʻihi a i ʻole nā ​​​​kūlana kaiapuni koʻikoʻi.

ʻO ka maʻamau, hana ʻia ka ʻōpala sanitary pad me ka ʻili composite polyethylene (PE)/polypropylene (PP), e hāʻawi ana i ka maʻalahi maikaʻi loa no ka hoʻolōʻihi ʻana a me ke sila ʻana. Me kahi ʻano matte a me ka manaʻo ʻoluʻolu, hāʻawi ia i ka pale ʻana i ka makū a me ka lepo, e pale pono ana i ka huahana me ka mālama ʻana i ka ikaika o ka ʻōpala.

Kākoʻo kēia kiʻiʻoniʻoni hui i ka māka laser UV, kahi e hoʻoulu ai ka laser i kahi hopena photochemical i loko o ka uhi, e hoʻololi ana i kona kala e hana i nā māka hina ma ka ʻili keʻokeʻo no nā lā hana a me nā helu batch. Hōʻoia kēia ʻano hana i nā māka maopopo a paʻa e mau ana ka pale ʻana i ka mae ʻana i ka wā mālama a me ka lawe ʻana i ka wā lōʻihi.

ʻO nā ʻeke ʻōpala meaʻai me kahi ʻili keʻokeʻo-kala laumania, i hana ʻia me ka pepa alumini (AL) a me ka hui PET, hoʻohana pinepine ʻia no ka ʻōpala meaʻai kiʻekiʻe. Loaʻa i kēia mau ʻeke kahi ʻālohilohi metala me kahi ʻano matte, e hāʻawi ana i ka makū maikaʻi loa, ka oxidation, a me ke kūpaʻa māmā, e hōʻoiaʻiʻo ana e noho hou a ʻōlinolino ka meaʻai i ka wā o ka lawe ʻana a me ka mālama ʻana.

Hoʻohana pinepine ʻia no nā pīni kope, ke kī, nā nati, nā mea ʻala, a me nā meaʻai māmā e ʻai ai, mālama kēia mau ʻeke i ka hou a me ke ʻala o ka meaʻai. Hoʻopau ka māka laser fiber i ka uhi ʻili, e hōʻike ana i kahi kala hohonu e hana i nā māka lā hana a me ka helu pūʻulu maopopo a paʻa e kūʻē i ka ʻaʻahu a me ka mae.

ʻO ka maʻamau, hana ʻia nā ʻeke ʻōpala noodles me ka mea hui BOPP/PE (biaxially oriented polypropylene/polyethylene). Hāʻawi ka papa waho BOPP i ka transparency kiʻekiʻe a me ka hiki ke paʻi maikaʻi loa, e ʻae ana i ka ʻike ʻia o nā noodles me ka hāʻawi ʻana i ke kūpaʻa makū no ka hou. He palupalu ka papa PE o loko, ʻaʻohe ʻawahia, a palekana i ka meaʻai, me nā waiwai sila wela ikaika e hōʻoia i kahi sila paʻa a pale i ka makū.

Ua koho ʻia kahi ʻāpana i uhi ʻia i ke keʻokeʻo ma ka ʻili BOPP no ka māka laser UV. Ma ka hoʻohana ʻana i ke kumumanaʻo hoʻololi kala laser, ua hoʻololi ʻia ke kala o ka uhi e paʻi i nā lā hana maopopo a me nā helu puʻupuʻu me ka ʻole o ka hou ʻana i ka ʻōpala. ʻO nā māka paʻa a kūpaʻa i ke komo ʻana e hōʻoia i ka palekana o ka huahana i ka wā o ka lawe ʻana a me ka mālama ʻana.

Hoʻohana ʻia ka ʻenehana māka laser UV ma ka lepili PET wrap-around o nā ʻōmole hoʻomaʻemaʻe maka cylindrical, e hōʻoiaʻiʻo ana i nā māka lā hana maopopo ma nā ʻili piʻo. Hana ka laser ma o kahi ʻano hoʻololi kala, kahi e hoʻoulu ai nā kukuna ikehu kiʻekiʻe i kahi hopena photochemical, e hoʻololi ana i ke ʻano molekala o ka ʻili PET e hana i nā māka hina-keʻokeʻo a ʻeleʻele paha me ka ʻole o ka wehe ʻana i nā mea.

He kūpono kēia ʻano hana no nā ʻili piʻo, me ka hopena wela haʻahaʻa e pale ai i ka hōʻino ʻana o ka ʻili a i ʻole ke ʻano ʻē.

ʻO nā ʻeke liʻiliʻi no ka wai i hoʻopaʻa ʻia e hana pinepine ʻia me ka mea hui PET/AL/PE. He paʻa a kūpaʻa ka papa PET waho i ke komo ʻana, ke ālai nei ka papa pepa alumini (AL) i ka mālamalama, ka oxygen, a me ka makū, ʻoiai ʻo ka papa PE o loko e hōʻoiaʻiʻo i ka palekana o ka meaʻai a me ka sila ʻana.

No ka hōʻailona ʻana i nā lā hana a me nā helu batch, ua hoʻopili ʻia ka māka laser UV i ka papa waho PET. Hoʻoulu ka laser i kahi hopena photochemical e hoʻololi i ke ʻano molekala o ka ʻili PET, e hana ana i nā māka hina a ʻeleʻele paha me ka ʻole o ka hou ʻana i ka ʻōpala. Hōʻoia kēia ʻano hana i nā māka maopopo a pale i ke komo ʻana me ka mālama ʻana i ka pono o ka pepa alumini a me nā papa PE, e pale ana i ka liki ʻana o ka wai.
