Kraft bepa rave sarudzo inosarudzika nekuda kwesimba rayo rakakura, kuita zvakasiyana-siyana, uye kuderera kwemamiriro ekunze. Iyo 100% inodzokororwa uye inoshamwaridzana nenharaunda, ine nhoroondo refu yekugadzirwa inosanganisira huni fiber, mvura, makemikari, uye kupisa. Kraft bepa rakasimba uye rinowedzera porous, zvichiita kuti ive yakakodzera kune yakakosha maitiro. Inoshandiswa zvakanyanya mukurongedza, senge makatoni nemabhegi emapepa, uye kune akasiyana marudzi akakamurwa zvichienderana nehunhu hwawo uye chinangwa.
1.Chiikraft bepa here?
Kraft bepa rinoreva bepa kana bhodhi rakagadzirwa kubva kumakemikari pulp uchishandisa kraft papermaking process. Nekuda kweiyo kraft pulping process, kraft bepa rine kusimba kwakanyanya, kuramba kwemvura, uye kuramba kubvarura, uye ruvara rwayo runowanzo yero-brown hue.
Kraft pulp ine ruvara rwakadzama kupfuura mamwe mapulp ehuni, asi inogona kucheneswa kugadzira pulp chena kwazvo. Yakanyatso bleached kraft pulp inoshandiswa mukugadzira mapepa emhando yepamusoro apo kusimba, kuchena, uye kuramba kutsvuka kwakakosha.
2. Nhoroondo uye Kugadzira Maitiro eKraft Paper
Kraft bepa, chinhu chinowanzo shandiswa kurongedza, chinopihwa zita rekuti pulping process. Kraft papermaking process yakagadzirwa naCarl F. Dahl muDanzig, Prussia (yava kunzi Gdańsk, Poland) muna 1879. Zita rokuti kraft rinobva pashoko rechiGerman rokuti "Kraft," rinoreva simba kana simba.
Zvinhu zvakakosha zvekugadzira kraft pulp ndeyehuni fiber, mvura, makemikari, uye kupisa. Kraft pulp inogadzirwa nekusanganisa matanda ehuni nemhinduro ye caustic soda uye sodium sulfide uye kuibika mu digester.
Mushure mekuita maitiro akasiyana-siyana ekugadzira akadai sekupfekedza, kubika, kucheneswa, kurova, saizi, chena, kucheneswa, kuongorora, kuumba, kupera mvura uye kudzvanya, kuomesa, kurongedza, uye kupeta, pamwe nekuomesera maitiro ekudzora, iyo kraft pulp inozopedzisira yashandurwa kuita. kraft bepa.
3. Kraft Paper vs. Regular Pepa
Vamwe vanogona kukakavara kuti ingori pepa, saka chii chakakosha nezve kraft paper?
Mumashoko akareruka, kraft bepa rakasimba.
Nekuda kweiyo kraft pulping process yambotaurwa, yakawanda lignin inobviswa kubva kraft pulp huni fibers, ichisiya kumashure akawanda. Izvi zvinopa bepa kurwisa kwayo kubvarura uye kusimba.
Unbleached kraft paper inowanzoita porous pane pepa renguva dzose, izvo zvinogona kuguma nemigumisiro yekudhinda zvishoma. Nekudaro, iyi porosity inoita kuti ive yakanyanya kukodzera kune mamwe maitiro akakosha, senge embossing kana kupisa stamping.
4.Zvikumbiro zveKraft Paper muPackaging
Nhasi, kraft bepa rinonyanya kushandiswa kumabhokisi ane marara uye mukugadzira mabhegi emapepa asina njodzi dzepurasitiki, seaya anoshandiswa simende, chikafu, makemikari, zvinhu zvevatengi uye hupfu.
Nekuda kwekugara kwayo uye kushanda kwayo, mabhokisi ane corrugated akagadzirwa nekraft bepa anozivikanwa zvakanyanya muindasitiri yekuburitsa uye logistics indasitiri. Aya mabhokisi anochengetedza zvigadzirwa uye anogona kutsungirira mamiriro ekufambisa akaomarara. Pamusoro pezvo, iyo inodhura-inoshanda yekraft bepa inoita kuti ive sarudzo yakakodzera yekusimudzira bhizinesi.
Kraft mapepa mabhokisi anowanzo shandiswa nemakambani kuzadzisa zvibodzwa zvebudiriro, achiratidza zvakajeka kuedza kwekuchengetedza kwezvakatipoteredza kuburikidza nerustic uye mbishi kutaridzika kwebrown kraft bepa. Kraft bepa rine huwandu hwakawanda hwekushandisa uye rinogona kupa zvakasiyanainnovative packagingmhinduro muindasitiri yemazuva ano yekurongedza.
5. Mhando dzeKraft Paper
Kraft bepa rinowanzochengetedza ruvara rwayo rwekutanga rwero-brown, zvichiita kuti ive yakakodzera kugadzirwa kwemabhegi uye mapepa ekuputira. Kune marudzi akasiyana-siyana ekraft bepa zvichienderana nemaitiro ayo uye mashandisirwo. Kraft bepa ishoko rakajairwa rebepa uye harina maitiro chaiwo. Inowanzo kupatsanurwa maererano nemaitiro ayo uye chinangwa chekushandiswa.
Neruvara, kraft bepa rinogona kuiswa mune rechisikigo kraft bepa, tsvuku kraft bepa, chena kraft bepa, matte kraft bepa, single-sided gloss kraft bepa, maviri-mavara kraft bepa, nevamwe.
Zvichienderana nemashandisirwo ayo, kraft bepa rinogona kukamurwa kuita yekurongedza kraft bepa, isina mvura kraft bepa, beveled kraft bepa, ngura-proof kraft bepa, patterned kraft bepa, insulating kraft paperboard, kraft stickers, nezvimwe.
Zvinoenderana nekuumbwa kwayo kwezvinhu, kraft bepa rinogona kuverengerwazve kuita rakadzokororwa kraft bepa, kraft musimboti bepa, kraft base bepa, kraft wax bepa, huni pulp kraft bepa, composite kraft bepa, nevamwe.
Mhando Dzakajairika dzeKraft Pepa
1. Yakanamirwa isina kubvongodzwa Kraft Paper (CUK)
Ichi chinyorwa chinoonekwa seyakanyanya kukosha vhezheni yekraft bepa. Iyo haipindi chero "bleaching" kana mamwe makemikari ekuwedzera, kunze kwemakemikari anoshandiswa mu kraft pulping process. Nekuda kweizvozvo, inozivikanwa zvakare seyakasimba unbleached kraft kana sulfite, inosanganisira 80% virgin fiber huni pulp / cellulose kraft pulp. Iyo inoratidzira yakanakisa kubvarura kuramba uye kuomarara kwakanyanya pasina kunyanyisa gobvu. Muchokwadi, ndiyo yakatetepa pane ese kraft mapepa ekurongedza substrates.
2. Solid Bleached Kraft Paper (SBS)
Nepo unbleached kraft paper ichionekwa seine hushamwari hwakatipoteredza nekuda kweruvara rwayo rwechisikigo uye kushaikwa kwemakemikari marapirwo, inogona kunge isiri iyo yakanakira sarudzo kune mamwe maapplication, senge kurongedza zveumbozha kana zvigadzirwa zvepamusoro. Muzviitiko izvi, bleached kraft paper inogona kusarudzwa nokuti ine nzvimbo yakatsetseka uye inopenya kutaridzika, iyo inogona kuwedzera kunaka kwekudhinda uye kupa kutaridzika kwakanyanya uye kunzwa.
3. Coated Recycled Board (CRB)
Coated recycled board inogadzirwa ne100% recycled kraft paper. Nekuti haina kugadzirwa kubva virgin fibers, iyo yakatarwa uye kushivirira ishoma pane iyo yakasimba bleached kraft paper. Nekudaro, yakadzokororwa kraft bepa zvakare yakachipa-yekurongedza substrate, ichiita kuti inyatso kukodzera kune maapplication ayo asingade yakakwira kubvarura kuramba kana simba, senge zviyo mabhokisi. Kune mabhokisi ane corrugated, mamwe marudzi anogona kuwanikwa nekuwedzera kraft paper layer.
