Nā ʻokoʻa ma waena o BOPP a me PET

I kēia manawa, ke ulu nei nā kiʻi ʻoniʻoni kiʻekiʻe a me nā kiʻi ʻoniʻoni i kahi pae ʻenehana hou. No ke kiʻiʻoniʻoni hana, ma muli o kāna hana kūikawā, hiki iā ia ke hoʻokō maikaʻi i nā koi o ka pahu kūʻai, a i ʻole e hoʻokō pono i nā pono o ka ʻoluʻolu o ka waiwai, no laila ʻoi aku ka maikaʻi o ka hopena a ʻoi aku ka hoʻokūkū ma ka mākeke. Maanei, e nānā mākou i nā kiʻi ʻoniʻoni BOPP a me PET

ʻO BOPP, a i ʻole Biaxially Oriented Polypropylene, he kiʻiʻoniʻoni i hoʻohana nui ʻia i ka hoʻopili ʻana a me ka lepili. Loaʻa ia i kahi kaʻina hana biaxial, e hoʻonui ana i kona mālamalama, ikaika, a me ka paʻi. ʻIke ʻia no kona maʻalahi, hoʻohana maʻamau ʻia ʻo BOPP i ka hoʻopili maʻalahi, nā lepili, nā lipine adhesive, a me nā noi lamination. Hāʻawi ia i ka ʻike huahana maikaʻi loa, ka lōʻihi, a hiki ke hoʻohana hou ʻia, e lilo ia i koho kaulana no nā pono ʻāpana like ʻole.

ʻO PET, a i ʻole Polyethylene Terephthalate, he polymer thermoplastic i hoʻohana nui ʻia no kona versatility a me ka maopopo. Hoʻohana maʻamau ʻia i ka hana ʻana i nā ʻōmole plastik no nā mea inu, nā ipu meaʻai, a me ka hoʻopili ʻana, ʻike ʻia ka PET a loaʻa iā ia nā waiwai pale maikaʻi e kūʻē i ka oxygen a me ka makū. He māmā, lōʻihi, a hiki ke hoʻohana hou ʻia, e lilo ia i koho kaulana no nā noi hoʻopili like ʻole. Hoʻohui ʻia, hoʻohana ʻia ʻo PET i nā fibers no ka lole, a me ka hana ʻana i nā kiʻiʻoniʻoni a me nā pepa no nā kumu like ʻole.

 

ʻokoʻa

ʻO PET ka polyethylene terephthalate, aʻo BOPP ke kū nei no ka polypropylene biaxially oriented. ʻO nā kiʻi ʻoniʻoni PET a me BOPP nā kiʻiʻoniʻoni ʻiliʻili lahilahi i hoʻohana pinepine ʻia no ka hoʻopili ʻana. ʻO nā mea ʻelua he mau koho kaulana no ka hoʻopili meaʻai a me nā noi ʻē aʻe, e like me nā lepili huahana a me nā pale pale.

E pili ana i nā ʻokoʻa ma waena o nā kiʻi ʻoniʻoni PET a me BOPP, ʻo ka ʻokoʻa ʻoi loa ke kumukūʻai. ʻOi aku ka maikaʻi o ke kiʻi ʻoniʻoni PET ma mua o ka kiʻiʻoniʻoni BOPP ma muli o kona ikaika a me nā waiwai pale. ʻOiai ʻoi aku ka maikaʻi o ke kiʻi ʻoniʻoni BOPP, ʻaʻole ia e hāʻawi i ka pale like a i ʻole nā ​​​​mea pale e like me ke kiʻi ʻoniʻoni PET.

Ma waho aʻe o ke kumukūʻai, aia nā ʻokoʻa i ka pale wela ma waena o nā ʻano kiʻiʻoniʻoni ʻelua. ʻO ka kiʻiʻoniʻoni PET he wahi heheʻe kiʻekiʻe ma mua o ka kiʻiʻoniʻoni BOPP, no laila hiki iā ia ke pale i nā mahana kiʻekiʻe me ka ʻole o ka warping a i ʻole ka emi ʻana. ʻOi aku ka paʻa ʻana o ke kiʻi ʻoniʻoni BOPP i ka wai, no laila hiki iā ia ke pale i nā huahana i maʻalahi i ka wai.

E pili ana i nā waiwai optical o nā kiʻi ʻoniʻoni PET a me BOPP, ʻoi aku ka maikaʻi o ke kiʻi ʻoniʻoni PET a me ka nani, aʻo ka kiʻiʻoniʻoni BOPP he hopena matte. ʻO ke kiʻi ʻoniʻoni PET ke koho maikaʻi loa inā ʻoe e ʻimi nei i kahi kiʻiʻoniʻoni e hāʻawi ana i nā waiwai optical maikaʻi loa.

Hana ʻia nā kiʻi ʻoniʻoni PET a me BOPP mai nā resins plastik akā aia nā mea like ʻole. ʻO ka PET ka polyethylene terephthalate, e hui pū ana i ʻelua monomer, ethylene glycol, a me terephthalic acid. Hoʻokumu kēia hui ʻana i kahi mea paʻa a māmā hoʻi i kūpaʻa loa i ka wela, nā kemika, a me nā solvents. Ma ka ʻaoʻao ʻē aʻe, hana ʻia ke kiʻi ʻoniʻoni BOPP mai ka biaxially-oriented polypropylene, kahi hui o polypropylene a me nā mea synthetic ʻē aʻe. He ikaika a māmā hoʻi kēia mea akā ʻaʻole hiki ke pale i ka wela a me nā kemika.

He nui nā ʻano like o nā mea ʻelua e pili ana i nā waiwai kino. He ʻokoʻa loa nā mea ʻelua a loaʻa ka mālamalama maikaʻi loa, e hoʻolilo iā lākou i mea kūpono no nā noi e koi ana i ka ʻike maopopo o nā ʻike. Hoʻohui ʻia, paʻa a maʻalahi nā mea ʻelua, e kūpono ia no nā noi like ʻole.

Eia nō naʻe, aia kekahi mau ʻokoʻa nui. ʻOi aku ka paʻakikī o PET ma mua o ka kiʻiʻoniʻoni BOPP a ʻaʻole hiki ke haehae a ʻokiʻoki paha. He kiʻekiʻe ka helu heheʻe ʻana o ka PET a ʻoi aku ke kūpaʻa i ka radiation UV. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka malleable kiʻi ʻoniʻoni BOPP a hiki ke hoʻolōʻihi ʻia a hana ʻia e kūpono i nā noi like ʻole.

 

hōʻuluʻulu manaʻo

I ka hopena, ʻokoʻa ka kiʻiʻoniʻoni pipi a me ka kiʻi Bopp. ʻO ka kiʻi ʻoniʻoni PET he kiʻiʻoniʻoni polyethylene terephthalate, e hana ana i ka thermoplastic hiki ke hoʻomehana ʻia a hoʻoheheʻe ʻia me ka nalowale ʻole o kona kūpaʻa. Loaʻa iā ia ke kūpaʻa dimensional maikaʻi loa, nā waiwai optical, a me ke kūpaʻa kemika, e lilo ia i koho maikaʻi loa no nā noi he nui. ʻO ka kiʻiʻoniʻoni Bopp, ma kekahi ʻaoʻao, he kiʻiʻoniʻoni polypropylene biaxially-oriented. He mea māmā akā ikaika me nā waiwai optical, mechanical, a me ka wela. He mea maikaʻi ia i nā noi kahi e pono ai ka mālamalama kiʻekiʻe a me ka ikaika kiʻekiʻe.

Ke koho nei ma waena o kēia mau kiʻiʻoniʻoni ʻelua, pono e noʻonoʻo i ka noi. He kūpono ke kiʻi ʻoniʻoni PET no nā noi e koi ana i ka paʻa o ka dimensional a me ke kūpaʻa kemika. ʻOi aku ka maikaʻi o ke kiʻi ʻoniʻoni Bopp no ​​nā noi e koi ana i ka mālamalama kiʻekiʻe a me ka ikaika kiʻekiʻe.

Lana ko mākou manaʻo ua kōkua kēia blog iā ʻoe e hoʻomaopopo maikaʻi i ka ʻokoʻa ma waena o nā kiʻiʻoniʻoni pipi a me Bopp a koho i ka mea i kūpono i kāu noi.
