Nā Kūlana (Material)
Nā ʻeke hikiwawe, ʻeke a me nā kiʻiʻoniʻoni Rollstock
Hoʻopili ʻia ka ʻeke paʻa e nā kiʻi ʻoniʻoni ʻē aʻe, ʻo ke kumu e hāʻawi i kahi pale maikaʻi o nā mea i loko mai nā hopena o ka oxidation, ka mākū, ka māmā, ka ʻala a i ʻole nā hui pū ʻana o kēia mau mea.No ka mea maʻamau, ʻokoʻa ke ʻano o nā mea i hoʻohana ʻia e ka papa waho, ka papa waena, a me ka papa o loko, nā inika a me nā mea hoʻopili.
1. Papa waho:
Hana ʻia ka papa paʻi waho me ka ikaika mechanical maikaʻi, ke kūpaʻa wela maikaʻi, ke kūpono paʻi maikaʻi a me ka hana optical maikaʻi.ʻO ka mea maʻamau no ka papa paʻi ʻia ʻo BOPET, BOPA, BOPP a me kekahi mau mea pepa kraft.
ʻO ka pono o ka papa waho e like me kēia:
| Nā kumu no ka nānā ʻana | hana |
| Ka ikaika mīkini | ʻO ke kū'ē huki, ke kū'ē i ka waimaka, ke kū'ē a me ke kū'ē |
| Keakea | Pale i ka oxygen a me ka makū, ka ʻala, a me ka pale UV. |
| Paʻa | ʻO ke kūpaʻa māmā, ke kūpaʻa ʻaila, ke kūpaʻa ʻana i nā mea organik, ka pale wela, ke kū anuanu |
| Hiki ke hana | ʻO ke koena friction, ʻokiʻoki thermal curl |
| Palekana olakino | ʻAʻole ʻona, māmā a ʻala ʻole |
| ʻO nā mea ʻē aʻe | ʻO ka māmā, ke aniani, ka pale māmā, ke keʻokeʻo, a hiki ke paʻi ʻia |
2. Papawaena
ʻO ka mea maʻamau i hoʻohana ʻia ma ka papa waena ʻo Al (aluminium film), VMCPP, VMPET, KBOPP, KPET, KOPA a me EVOH a me nā mea ʻē aʻe. ʻO ka papa waena no ka pale o CO2, Oxygen, a me Nitrogen e hele i loko o nā pūʻolo o loko.
| Nā kumu no ka nānā ʻana | hana |
| Ka ikaika mīkini | Huki, hoʻopaʻapaʻa, haʻihaʻihaʻi, kūʻē i ka hopena |
| Keakea | Pale o ka wai, ke kinoea a me ka ʻala |
| Hiki ke hana | Hiki ke laminated ma nā ʻaoʻao ʻelua no nā papa waena |
| ʻO nā mea ʻē aʻe | E pale i ka hele ʻana o ka mālamalama. |
3. Papa loko
ʻO ka mea nui loa no ka papa o loko me ka ikaika hoʻopaʻa maikaʻi.ʻO CPP a me PE ka mea kaulana loa e hoʻohana ʻia e ka papa o loko.
| Nā kumu no ka nānā ʻana | hana |
| Ka ikaika mīkini | ʻO ke kū'ē huki, ke kū'ē i ka waimaka, ke kū'ē a me ke kū'ē |
| Keakea | E mālama i kahi ʻala maikaʻi a me ka adsorption ow |
| Paʻa | ʻO ke kūpaʻa māmā, ke kūpaʻa ʻaila, ke kūpaʻa ʻana i nā mea organik, ka pale wela, ke kū anuanu |
| Hiki ke hana | ʻO ke koena friction, ʻokiʻoki thermal curl |
| Palekana olakino | Nontoxic, emi ʻala |
| ʻO nā mea ʻē aʻe | ʻAlohilohi, inpermeable. |
