Puke lāʻau lapaʻau i hana anu

ʻO ka pahu alumini kahi mea hoʻopili lāʻau maikaʻi, ʻoiai ʻo ka alumini alumini i hoʻokumu ʻia i ke anu he mea hoʻopihapiha lāʻau lapaʻau me ka hana koʻikoʻi. No ka pahu lāʻau lapaʻau, ʻO ka alumini anu pepa i hoʻohana mau ʻia he hale laminated e hoʻohui i nā mea pale o ka alumini me nā papa hou e hoʻokō ai i nā hana e like me ka pale pale., hiki ke paʻi ʻia, a me ka sila ana.

ʻO ka hale i hana ʻia i ke anuanu kūpono no ka ʻeke lāʻau

ʻO ke ʻano o ka pepa anu no nā lāʻau lapaʻau, maʻamau alumini pepa anu no ka hoʻopili ʻana i ka lāʻau lapaʻau hiki ke loaʻa i nā papa aʻe:

a. Polyester (PET) papa kiʻiʻoniʻoni (12–25 microns)

– Ke kumu: hoʻohana ʻia ma ke ʻano he kiʻiʻoniʻoni kumu e hāʻawi i ka ikaika mechanical a me ka paʻi ʻana.

– Nā hiʻohiʻona: kūlana kūlana kiʻekiʻe, ʻili paʻi paheʻe, maikaʻi ke kūpale waimaka.

– mānoanoa: 12–25 microns, ma muli o nā koi no ka maʻalahi a me ka ikaika.

b. Papa hoʻopili (1–3 microns)

– Ke kumu: hoʻopaʻa kiʻiʻoniʻoni polyester i ka pahu alumini.
– Nā hiʻohiʻona: Heat activated adhesive or pressure sensitive adhesive e hōʻoiaʻiʻo i kahi paʻa paʻa me ka ʻole o ka hoʻopaʻapaʻa ʻana i nā waiwai pale o ka foil.

c. Papa aluminika (6-9 microns)

– Ke kumu: Hana ʻo ia ma ke ʻano he papa pale mua e pale ai i ka lāʻau mai ka makū, māmā, oxygen a me nā mea haumia ʻē aʻe.
– Nā hiʻohiʻona: Pale kiʻekiʻe i nā kinoea a me ka maʻamau, ʻO ka hoʻomaʻamaʻa māmā a ʻaʻohe mea ʻawaʻawa.
– mānoanoa: 6-9 microns (7mic,9mic)ʻo ia ka mānoanoa maʻamau no nā noi pepa anu no nā lāʻau lapaʻau.

d. ʻO ka uhi sila wela/ka papa mua (1-5 microns)

– Ke kumu: Hāʻawi i kahi ʻili i hiki ke hoʻopaʻa ʻia i ka wela i nā ʻeke blister a i ʻole nā ​​​​substrat ʻē aʻe.
– Nā hiʻohiʻona: Ua kūpono kēia papa me ka papa hoʻopaʻa ʻana o nā kiʻi ʻoniʻoni blister PVC a i ʻole PVDC. It ensures a secure seal without affecting the drug inside.
– Type: Typically a heat seal lacquer or primer that adheres well to PVC, PVDC or other common blister substrates.

Enhanced cold foil structure

In some cases, aluminum cold foil may have additional layers for better performance:

e. Protective coating (koho, 1-2 microns)
– Ke kumu: Enhance the abrasion and chemical resistance of the foil.
– Nā hiʻohiʻona: Provide an additional barrier, especially important for highly sensitive pharmaceuticals.

Key to cold aluminum for pharmaceutical packaging

Cold-formed aluminum foil as the outer packaging of pharmaceuticals needs to have the characteristics of protecting the pharmaceuticals and blocking external factors, so the key considerations for pharmaceutical cold foil packaging are four aspects:
1. Barrier: The aluminum foil layer provides an excellent barrier against moisture, oxygen a me nā kukui UV e pale i ka paʻa a me ka pono o ka lāʻau.
2. Hiki ke paʻi: Hiki i ka papa kiʻiʻoniʻoni PET ke hiki i ka lepili kiʻekiʻe a me ka paʻi brand, He mea koʻikoʻi ia no ka hoʻokō ʻana i ke kānāwai a me ka ʻike ʻana i ka huahana.
3. Hoʻolikelike: Pono e kūpono ke ʻano me nā mīkini hoʻopihapiha lāʻau lapaʻau a hoʻokō i nā koi kānāwai (e.g. FDA, EMA).
4. Hoʻokō sila: Pono e hoʻopaʻa ʻia ka hoʻopaʻa ʻana i ka wela-seal i kahi sila ikaika me ka substrate blister packaging (e.g. PVC, PVDC i uhi ʻia i ka PVC a i ʻole Aclar® laminate).

Maʻamau ka mānoanoa o ka pepa anu:

– PET kiʻiʻoniʻoni: 12–25 microns
– Papa hoʻopili: 1–3 microns
– Alumini pepa: 6–9 microns
– Ka uhi sila wela: 1–5 microns

Loaʻa kēia ʻano i kahi kaulike ma waena o ka pale pale, hiki ke paʻi a me ka hoʻopaʻa ʻana. He kūpono loa ka alumini i hana ʻia i ke anuanu no nā mea hoʻopili lāʻau lapaʻau ma muli o kona ʻano hoʻonohonoho, maikaʻi ductility, nā waiwai pale maikaʻi, nā waiwai hoʻopaʻa maikaʻi a me nā pono ʻē aʻe he nui.
