ʻO ka EVA he mea ʻilika i haku ʻia me ka ethylene (E) a me ka vinyl acetate (VA). Hiki ke hoʻololi ʻia ka ratio o kēia mau kemika ʻelua e hoʻokō i nā pono noi like ʻole. ʻOi aku ka kiʻekiʻe o ka vinyl acetate (VA content), ʻoi aku ka kiʻekiʻe o kona ʻike, palupalu a paʻakikī.
ʻO nā hiʻohiʻona o EVA a me PEVA:
1. Biodegradable: ʻAʻole ia e pōʻino i ke kaiapuni ke hoʻolei ʻia a puhi ʻia paha.
2. E like me ke kumukūʻai PVC: ʻoi aku ka maikaʻi o ka EVA ma mua o ka PVC ʻona, akā ʻoi aku ka maikaʻi ma mua o PVC me ka ʻole o ka phthalates.
3. Māmā: ʻO ka nui o ka EVA mai ka 0.91 a i ka 0.93, aʻo ka PVC he 1.32.
4. ʻAʻala ʻole: ʻAʻole i loko o ka EVA ka amonia a i ʻole nā mea ʻala ʻē aʻe.
5. ʻAʻohe metala kaumaha: Hoʻokō ia i nā lula pāʻani pili honua (EN-71 Māhele 3 a me ASTM-F963).
6. ʻAʻole Phthalates: He kūpono ia i nā mea pāʻani a nā keiki a ʻaʻole ia e hoʻokuʻu i ka plasticizer.
7. ʻO ke aniani kiʻekiʻe, ka palupalu a me ka paʻakikī: ākea loa ka laulā noi.
8. Super haʻahaʻa wela pale (-70C): kūpono no ka hau hau.
9. ʻO ke kūpaʻa wai, ka paʻakai a me nā mea ʻē aʻe: hiki ke kūpaʻa i ka nui o nā noi.
10. Hoʻopili wela kiʻekiʻe: hiki ke hoʻopili paʻa ʻia i ka nylon, polyester, canvas a me nā lole ʻē aʻe.
11. Haʻahaʻa lamination wela: hiki ke hoʻoikaika i ka hana.
12. Hiki ke pa'i 'ia ka pale a pa'i 'ia ka 'offset: hiki ke ho'ohana 'ia no nā huahana nani (akā pono e ho'ohana i ka inika EVA).
ʻO ka lining EVA, e like me ka inoa e hōʻike nei, he huahana i waiho ʻia i loko o kēia pahu EVA, a laila makemake ʻia kahi pūʻolo ma waho, a kau ʻia ka lining EVA i loko o kēia pūʻolo. Hiki i kēia pūʻolo ke pahu hao metala, a i ʻole ka pahu pahu keʻokeʻo a i ʻole ka pahu pahu.
ʻO ka hoʻokaʻawale ʻana o nā mea hoʻonaninani EVA
Hoʻokaʻawale nui ʻia ʻo EVA packaging lining i nā wahi aʻe:
1. Haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa e pili ana i ke kaiapuni EVA, ʻeleʻele, keʻokeʻo a me ke kala.
2. Kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe e pili ana i ke kaiapuni EVA, ʻeleʻele, keʻokeʻo a me ke kala.
3. EVA keena pani 28 degere, 33 degere, 38 degere, 42 degere.
4. EVA keena hamama 25 degere, 38 degere
