Te kimi i te tikapepa kraft mō te hanga envelopaKa tīmata mā te mārama ki ngā kaupapa hanga taketake o te rauemi. He mea hanga tēnei pepa mai i ngā muka cellulose rakau mā te tukanga matū kraft, he kaha ā-taiao, he maha ngā whakamahinga, ā, he hoa hoki ki te taiao.
He mea hanga motuhake te rauemi hei whakahaere i ngā uauatanga o ngā raina whakaputa aunoa, me te tiaki hoki i ngā tuhinga, ngā rārangi pukapuka, me ngā taonga mama i te wā e haere ana. Mō ngā whare tā B2B me ngā kamupene kawe taonga, mā te tohu i te turanga tika ka ārai i ngā aukati mīhini utu nui me te moumou rauemi.
Ngā whakaritenga tahuri matua
Me hiahia ngā kaihanga ki te pepa e pai ana te whanonga i runga i te matapaepapa whakaputaHe tere te oma o ngā mīhini huri kōpaki, mai i te 500 ki te 1,200 kōpaki ia meneti. I ēnei tere, me tino pai te takai o te pepa, me te kore e pakaru ngā tuitui.
Ko te pakari tētahi atu āhuatanga nui; ki te ngoikore rawa te pepa, ka aukati i te mīhini whakapiko, ka nui te utu mō te wā kore mahi, ā, ka nui hoki ngā hapa. Hei tāpiri, me whakaae te mata ki ngā kāpia paerewa me ngā kiriata whakapiri matapihi kia pai ai te hononga, kia tere ai te whakapiripiri (e kiia ana i raro i te 0.5 hēkona) ka hanga he hononga pumau, pumau.
Ngā tikanga whakatakotoranga matua
Hei hoko i te rauemi tika, me kōrero ngā kaihoko i te reo o ngā mira pepa. Ko te karamu mō ia mita tapawha (GSM) te mea e whakatau ana i te taumaha me te matotoru, e pā tika ana ki te roa me ngā utu tuku whakamutunga.
Ko te ahunga mīhini (MD) me te ahunga whakawhiti (CD) e whakaahua ana i te tūnga o ngā muka, e pā ana ki te haehae me te piko o te pepa i ngā kopa o te kōpaki. He mea nui anō hoki te nui o te makuku ki te angitu o te hurihanga. He maha ngā wā e hiahiatia ana he taumata makuku e arohia ana i waenga i te 5% me te 7%, ahakoa he rerekē tēnei i runga i te mira me te āhuarangi ā-rohe; hei tauira, ko ngā taiao haumākū teitei me whakarerekē pea i ngā taumata makuku hei ārai i te pepa mai i te piko, te mimiti, te pakarukaru rānei i te wā e rongoa ana me te tukatuka ana i te whare putunga.

Ngā kōwhiringa pepa parauri tūturu, mā, me te pepa pania
Ko te āhua o te pepa e whakatau ana i tōna whai huatanga me tōna pānga ki te taiao.Kraft parauri tūturu kāore i whakamaHe tino pai ki te taiao, ā, ka pirau hoki, nō reira he mea tino pai ki ngā waitohu tauwhiro e hiahia ana ki te whakaiti i ō rātou tapuwae waro.
Ka pāngia te kraft mā e te tukanga whakama - he mea nui te matū motuhake e whakamahia ana, pērā i te Elemental Chlorine-Free (ECF) me te Totally Chlorine-Free (TCF) mō ngā kereme pumau - kia puta ai he papamuri mārama, he rerekē hoki mō ngā hoahoa whakatairanga tae kanapa. Heoi, ka taea e te whakama te whakaiti i te kaha o te muka mā te 5% ki te 10% pea, ko te tikanga me whakanui ake e ngā kaihoko te GSM kia rite ki te roa o te wā e rite ana ki te roa o te kōpaki parauri. Kei te wātea hoki ngā kōwhiringa paninga, e tāpiri ana i ngā ārai ātete makuku, i ngā poly-lining rānei mō ngā mōkihi e hiahia ana ki te tiaki huarere tāpiri, ahakoa he mea nui kia mōhio ko te kraft paninga poly-canned he maha ngā wā kāore e taea te hangarua i roto i ngā awa paerewa.
Kōwhiria te Pepa Kraft Tika
Ko te whiriwhiri i te pepa kraft tino tika ko te whakamātautau i te rauemi i roto i ngā horopaki o te ao tūturu, me te whakataurite i aua hua ki ngā hua o te kamupene.
E kore te pepa kaha rawa atu o te ao e āwhina mēnā kāore e taea te pupuri tika i te mangumangu, ka ārai i te pūreretā whakarerekē, ka nui rawa rānei te utu mō te tuku nui.
Ngā taahiraa whakamātautau tā
I mua i te whakaae ki tētahi ota nui, me whakatinana e ngā kaiwhakawhiti he rārangi arowhai tirotiro tika. Me tono ngā tīma hokongā tiwhikete mirao te tātaritanga (COA), manatokohia te ōritetanga o te caliper puta noa i te rōra, ā, tirohia mēnā he kōpikopiko i ngā taumata makuku e hiahiatia ana.
Muri iho, me whakahaere e ngā kaitahuri ngā whakamātautau tānga mō te tānga flexo, te tānga offset rānei. Me maeneene te mata o te pepa kia taea ai te hopu i ngā taipitopito pai o te waehere pae engari kia rite te kakano kia tere te mimiti i te mangumangu me te kore e pania. Ka inehia tēnei e ngā mira mā te whakamahi i te tauine maeneene o Bendtsen; he pai te pānui o te 200 ki te 400 ml/min mō te tānga envelopu paerewa. He mahi mohio tonu te whakahaere i tētahi puranga whakamātautau 5,000-wahi hei tirotiro i te piri o te mangumangu, te mārama o te waitohu, me te pai o te piri o ngā piripiri ki ngā taupoki pepa i raro i ngā āhuatanga whakamaroke noa.
Te whakataurite i te pepa ki ngā hiahia pakihi
Hei whakamutunga, me rite ngā whakaritenga ki ngā hiahia whakahaere a te kaiwhakamahi whakamutunga. Ko ngā umanga pūtea e tuku ana i ngā tuhinga tairongo me nui te māramatanga (he maha ngā wā ka tohua neke atu i te 95%), ā, ka hiahiatia pea he tae haumarutanga ritenga kua tāia ki roto. Nā te mea he whakaritenga motuhake te māramatanga me te tae haumarutanga, ā, kāore e taea e rāua anake te whakapūmau i te muna katoa, he maha ngā wā ka honoa ngātahitia rāua.
Ko ngā waitohu hokohoko ipurangi me ngā kamupene kawe rauemi he mea nui ki ngā mea mama, pakari hoki, hei whakaiti i ngā utu tuku mō ia waeine. I te wā e rapu ana i ēnei rauemi, me whai whakaaro hoki ngā tīma hoko ki ngā rahinga ota iti rawa (MOQ).Ngā rōra nunui ritengaKo te tikanga, e 3 ki te 5 tana te nui o te hanga e hiahiatia ana. Mā te whakataurite i ngā whakaritenga hangarau ki te kaha rokiroki, ngā whāinga tutuki i ngā whakaritenga, me ngā here tahua ka pai te whakahaerenga o te hanga, ā, ka whai hua hoki.
Hei ārahi i te whakatau whakamutunga, ka taea e ngā kaihoko te whakarite i ā rātou momo kōpaki ki ngā paihere whakatakotoranga kua tūtohutia:
