Ua lilo ka pepa Kraft i mea i koho ʻia ma muli o kona ikaika kiʻekiʻe, versatility, a me ka hopena haʻahaʻa o ke kaiapuni. He 100% hiki ke hoʻohana hou ʻia a pili kaiapuni, me ka mōʻaukala lōʻihi o ka hana ʻana e pili ana i nā fila lāʻau, ka wai, nā kemika, a me ka wela. ʻOi aku ka ikaika o ka pepa Kraft a ʻoi aku ka porous, kūpono ia no nā kaʻina hana kūikawā. Hoʻohana nui ʻia ia i ka hoʻopili ʻana, e like me nā pahu pahu a me nā ʻeke pepa, a aia nā ʻano ʻano like ʻole e like me ko lākou ʻano a me ke kumu.
1. He ahahe pepa kraft?
ʻO ka pepa Kraft e pili ana i ka pepa a i ʻole ka pepa pepa i hana ʻia mai ka pulp kemika me ka hoʻohana ʻana i ke kaʻina hana kraft papermaking. Ma muli o ke kaʻina hana kraft pulping, loaʻa i ka pepa kraft ke kūpaʻa maikaʻi loa, ka pale wai, a me ka pale ʻana i ka waimaka, a ʻo kona waihoʻoluʻu he hue melemele-ʻeleʻele.
ʻOi aku ka hohonu o ka waihoʻoluʻu o Kraft pulp ma mua o nā pulp lāʻau ʻē aʻe, akā hiki ke bleach e hana i kahi pulp keʻokeʻo loa. Hoʻohana ʻia ka pulp kraft piha piha i ka hana ʻana i ka pepa kiʻekiʻe kahi mea koʻikoʻi ka ikaika, keʻokeʻo, a me ke kū'ē ʻana i ka melemele.
2. Ka Mo'olelo a me ka Hana Hana o ka Pepa Kraft
ʻO ka pepa Kraft, kahi mea hoʻohana maʻamau, ua kapa ʻia no kāna hana pulping. Ua hoʻokumu ʻia ke kaʻina hana kraft e Carl F. Dahl ma Danzig, Prussia (i kēia manawa ʻo Gdańsk, Polani) i ka makahiki 1879. Ua loaʻa ka inoa kraft mai ka huaʻōlelo Kelemania ʻo "Kraft," ʻo ia hoʻi ka ikaika a i ʻole ke ola.
ʻO nā kumu kumu no ka hana ʻana i ka pulp kraft he mau lāʻau, ka wai, nā kemika, a me ka wela. Hoʻokumu ʻia ka pulp Kraft ma o ka hui ʻana i nā ʻili lāʻau me kahi hopena o ka soda caustic a me ka sodium sulfide a hoʻomoʻa iā lākou i loko o kahi digester.
Ma hope o ka hana ʻana i nā kaʻina hana like ʻole e like me ka impregnation, ka kuke ʻana, ka pulp bleaching, ka hahau ʻana, ka nui ʻana, ka keʻokeʻo, ka hoʻomaʻemaʻe ʻana, ka nānā ʻana, ka hana ʻana, ka maloʻo a me ke kaomi ʻana, ka maloʻo, ka calendering, a me ka wili ʻana, me ka mana o ka kaʻina hana, ua hoʻololi ʻia ka pulp kraft. pepa kraft.
3. Pepa Kraft vs. Pepa mau
Hoʻopaʻapaʻa paha kekahi he pepa wale nō, no laila he aha ka mea kūikawā o ka pepa kraft?
Ma nā ʻōlelo maʻalahi, ʻoi aku ka ikaika o ka pepa kraft.
Ma muli o ke kaʻina hana kraft pulping i ʻōlelo ʻia ma mua, ua hoʻoneʻe ʻia ka lignin mai ka kraft pulp wood fibers, e waiho ana i nā mea hou aku. Hāʻawi kēia i ka pepa i kona kūpaʻa waimaka a paʻa.
ʻOi aku ka porous o ka pepa kraft unbleached ma mua o ka pepa maʻamau, ʻoi aku ka maikaʻi o nā hopena paʻi. Eia nō naʻe, ua kūpono kēia porosity no kekahi mau kaʻina hana kūikawā, e like me ka embossing a i ʻole ka hōʻailona wela.
4. Nā noi o ka pepa Kraft i ka Packaging
I kēia lā, hoʻohana nui ʻia ka pepa kraft no nā pahu corrugated a i ka hana ʻana i nā ʻeke pepa me ka ʻole o nā pōʻino plastik, e like me nā mea i hoʻohana ʻia no ka sima, nā meaʻai, nā kemika, nā mea kūʻai aku, a me ka palaoa.
Ma muli o kona lōʻihi a me ka hoʻomaʻamaʻa, kaulana loa nā pahu corrugated i hana ʻia me ka pepa kraft i ka ʻoihana hoʻopuka a me ka logistic. Mālama maikaʻi kēia mau pahu i nā huahana a hiki ke kū i nā kūlana halihali koʻikoʻi. Eia kekahi, ʻo ke kumu kūʻai o ka pepa kraft he mea kūpono ia no ka hoʻomohala ʻana i ka ʻoihana.
Hoʻohana pinepine ʻia nā pahu pepa Kraft e nā ʻoihana e hoʻokō i nā pahuhopu hoʻomohala hoʻomau, e hōʻike pono ana i nā hoʻoikaika ʻana i ke kaiapuni ma o ke ʻano o ka pepa kraft brown. Loaʻa i ka pepa Kraft ka nui o nā noi a hiki ke hāʻawi i nā ʻano like ʻolehōʻano hounā hāʻina i loko o ka ʻoihana paʻi o kēia lā.
5. Nā ʻano o ka pepa Kraft
Paʻa pinepine ka pepa Kraft i kona waihoʻoluʻu melemele-ʻeleʻele mua, i kūpono ia no ka hana ʻana i nā ʻeke a me ka pepa ʻōwili. Aia nā ʻano like ʻole o ka pepa kraft e pili ana i kāna mau waiwai a me nā noi. He huaʻōlelo maʻamau ka pepa Kraft no ka pepa a ʻaʻohe ona kūlana kikoʻī. Hoʻokaʻawale ʻia e like me kāna mau waiwai a me ka hoʻohana ʻana.
Ma ka waihoʻoluʻu, hiki ke hoʻokaʻawale ʻia ka pepa kraft i loko o ka pepa kraft maoli, pepa kraft ʻulaʻula, pepa kraft keʻokeʻo, pepa kraft matte, pepa kraft gloss ʻaoʻao hoʻokahi, pepa kraft ʻelua kala, a me nā mea ʻē aʻe.
Ma muli o kāna mau noi, hiki ke hoʻokaʻawale ʻia ka pepa kraft i ka pepa kraft packaging, pepa kraft wai, pepa kraft beveled, pepa kraft rust-proof, pepa kraft patterned, insulating kraft paperboard, kraft stickers, a me nā mea hou aku.
E like me ka mea i haku ʻia, hiki ke hoʻokaʻawale ʻia ka pepa kraft i ka pepa kraft recycled, kraft core pepa, kraft base pepa, kraft wax pepa, lāʻau pulp kraft pepa, composite kraft pepa, a me nā mea ʻē aʻe.
Nā ʻano maʻamau o ka pepa Kraft
1. Pepa Kraft i hoolele ole ia (CUK)
Ua manaʻo ʻia kēia mea ʻo ke ʻano maʻamau o ka pepa kraft. ʻAʻole ia e hana i kekahi "bleaching" a i ʻole nā mea hoʻohui kemika, ʻokoʻa mai nā kemika i hoʻohana ʻia i ke kaʻina hana kraft pulping. ʻO ka hopena, ua ʻike ʻia ʻo ia he kraft solid unbleached a i ʻole sulfite, nona ka 80% virgin fiber wood pulp/cellulose kraft pulp. Hōʻike ʻo ia i ke kūpaʻa waimaka maikaʻi a me ka ʻoʻoleʻa kiʻekiʻe me ka ʻole o ka mānoanoa. ʻO ka ʻoiaʻiʻo, ʻo ia ka ʻoi loa o nā substrates pepa kraft pepa.
2. Pepa Kraft bleached paʻa (SBS)
ʻOiai ua manaʻo ʻia ʻo ka pepa kraft unbleached i ʻoi aku ka maikaʻi o ke kaiapuni ma muli o kona kala kūlohelohe a me ka nele o nā lāʻau kemika, ʻaʻole paha ʻo ia ke koho maikaʻi loa no kekahi mau noi, e like me ka hoʻopili ʻana no nā huahana momona a kiʻekiʻe paha. I kēia mau hihia, ʻoi aku ka maikaʻi o ka pepa kraft bleached no ka mea he ʻoi aku ka maʻalahi o ka ʻili a me ka hiʻohiʻona ʻālohilohi, hiki ke hoʻonui i ka maikaʻi o ka paʻi ʻana a hāʻawi i kahi hiʻohiʻona ʻoi aku ka maikaʻi.
3. Papa Ho'opi'i Hou 'ia (CRB)
Hana ʻia ka papa i hoʻopaʻa ʻia me 100% pepa kraft recycled. No ka mea, ʻaʻole ia i hana ʻia mai nā fiber puʻupaʻa, ʻoi aku ka liʻiliʻi o kāna mau kikoʻī a me nā hoʻomanawanui ma mua o ka pepa kraft bleached paʻa. Eia nō naʻe, ʻo ka pepa kraft i hana hou ʻia he substrate puʻupuʻu haʻahaʻa haʻahaʻa, kūpono ia no nā noi ʻaʻole koi i ke kūpaʻa waimaka kiʻekiʻe a i ʻole ka ikaika, e like me nā pahu cereal. No nā pahu corrugated, hiki ke loaʻa i nā ʻano like ʻole me ka hoʻohui ʻana i nā papa pepa kraft.
