ʻO ka pahu lāʻau lapaʻau maʻamau a mākou a ʻoi aʻe paha e launa pū me, ʻo kahi laʻana, maʻamau anu lāʻau hoʻopili ili he papa o pepa alumini no ka hoʻopili ʻana, Manaʻo ka poʻe he nui kēia papa o ka alumini alumini he papa ʻokoʻa wale nō o ke kiʻi ʻoniʻoni alumini, i ka ʻoiaʻiʻo, ʻoiai ke nānā aku ʻo ia i kahi ʻāpana alumini, akā, he ʻano mea like ʻole kona ʻano no ka composite.

Hoʻokaʻawale ʻia ke ʻano o nā lako lāʻau lapaʻau maʻamau i: papa ʻili (papa pai), papa pale (alumini pepa), papa loko (papa hoʻopaʻa wela) pipili (VC) ʻano papa-nui. Hana ʻia kēlā me kēia papa i nā mea like ʻole a lawelawe i kahi kumu like ʻole. Hoʻopili ʻia nā ʻāpana ʻekolu me kahi mea hoʻopili. A ua māhele ʻia ka paʻi ʻana i ka paʻi i loko a me ka paʻi waho, paʻi ʻia ma ka ʻaoʻao o loko o ka papa pale, hiki ke paʻi ʻia ka paʻi waho ma ka ʻaoʻao o loko o ka ʻili o ka ʻili..

Loaʻa i kēia mau papa nā hana like ʻole a me nā ʻano waiwai, ʻO ka ʻili alumini alumini ka paʻi a me ka hoʻonaninani maikaʻi, pale wela ikaika, ʻaʻahu kūʻē. Ke paʻalua a multi-layer paʻakikī, hiki ke pāʻani i ka ʻili o ka ʻili; ʻO kēia papa o nā mea hoʻohana maʻamau he PET, BOPP, PT, pepa, HANA, etc., maʻamau e like me nā huahana like ʻole e koho i ka mea kūpono.

Lapa pale waena: ʻo ka mea nui ke pāʻani i kahi hana pale, keia papa o na mea e hiki ai ke pale aku i ke komo ana o ke kinoea o loko a me waho a wai paha, ka pale ʻana i nā lāʻau i loko. I ka manawa like, pono nō hoʻi e loaʻa ka pale māmā maikaʻi e pale ai i kekahi mau lāʻau pale māmā mai ka ʻike ʻana i ka lā. Pono nā ʻāpana pale a pau i kahi kokoke i ka puʻupuʻu e like me ka hiki. ʻO kēia papa o nā mea maʻamau i hoʻohana ʻia he alumini foil a i ʻole ke kiʻi aluminized, HANA, EVOH, PVDC, etc.

Papa loko: e pili pono ana ka papa o loko me ka laau, ʻAʻole koi ʻia kēia papa e launa pū me ka ʻeke e hana i ka corrosion a i ʻole ke komo ʻana; He laumania ka ʻili o loko a hiki ke kū i ka wela a i ke anu. ʻO nā mea maʻamau ka PE, PP, EVA a pēlā aku.

Hoʻopili: Hoʻohana ʻia ka ʻāpana paʻa e hoʻopaʻa i ka paʻa ʻana ma waena o nā papa. ʻO ka mea maʻamau i haku ʻia me nā mea pili, mea hoola, mea hoʻoheheʻe, nā mea hoʻohui ʻē aʻe (mea hoʻopololei, mea hoʻopiha, mea hoʻoheheʻe).
