Nā Kūlana Nānā Nui no nā Huahana Pepa

Pepa kumu po'o: Pono ka pa'a pa'a a me ka 'o'ole'a ki'eki'e o ka pepa pa'a. Pono kekahi degere o ka elasticity no ka mālama ʻana i ka hiki ke hoʻopaʻa haʻalulu a me ke kaomi ʻana o nā pahu i hana ʻia. No laila, ʻo ka ikaika o ka pohā a me ka ikaika o ke apo (a i ʻole ka ikaika paʻa palahalaha) nā hōʻailona nui e hōʻike ana i ka ikaika o ka pepa kumu corrugated. Eia kekahi, pono e mālama ʻia ka moisture index. Inā liʻiliʻi loa ka makū, e maʻalili ka pepa a nahā paha i ka wā e hana ai i ka corrugate. ʻO ka nui o ka wai e hoʻopilikia i ka hana. Ma keʻano maʻamau, pono ka maʻamau o ka wai ma kahi o 10%.

ʻO Cellophane: ʻO ka Cellophane ke aniani i ka waihoʻoluʻu, ʻōmaʻomaʻo ma ka ʻili, ʻaʻahu i ka mānoanoa, palupalu a hiki ke kikoo. E pehu a palupalu ma hope o ka hoʻokomo ʻia ʻana i ka wai, a e emi maoli ma hope o ka maloʻo ʻana. He kiʻekiʻe ka hoʻoheheʻe wai a hiki i nā wrinkles a hiki i ka paʻa i ka wā e ʻike ʻia i ka makū. Eia kekahi, ma muli o ka hoʻonohonoho like ʻana o nā microcrystals cellulose i ka ʻaoʻao longitudinal, nui ka ikaika lōʻihi o ka pepa a he liʻiliʻi ka ʻaoʻao transverse. Inā loaʻa nā māwae, e haki ia ma lalo o ka ikaika liʻiliʻi. ʻO ka Cellophane ka lewa, ka aila a me ka wai.

Pepa paʻi Offset: Hoʻohana ʻia ka pepa offset no ka paʻi ʻana i nā kala he nui. Ma waho aʻe o ke keʻokeʻo maikaʻi a me ka liʻiliʻi o ka lepo, loaʻa iā ia nā koi kiʻekiʻe no ka paʻa o ka pepa, ka ikaika tensile, a me ka pale ʻana. I ka wā e paʻi ʻia ai, ʻaʻole e hoʻoheheʻe ka ili o ka pepa i ka lint, ka pauka, a i ʻole ka paʻi ʻana. Ua like nā koi me ka pepa i uhi ʻia.
