Te whakamārama i te kōpae BOPP i tāwhai kē atu i ngā whakamātua ārā: He whakamārama

He aha te take i whakamāhinga ai i te kōpae BOPP i tēnei wā hei whiriwhiri tuatahi

Inā whāia e te kaihoko i ngā whakamātautau whakamutunga o te whakaprint, ka tū a BOPP precoated film, kāore he tohu, engari i te hāngai o ngā āhua o te kōpae ki ngā whāinga ōkawa o te whakamahinga maha, he nui ngā whāinga. Ko te polypropylene biaxially oriented he kōpae e whai ana i te pūmau o te āhua, te whakamānātanga ki te wai, me te whakamārama o ngā whakaahua, ā, he uaua tonu te whakamātua i ēnei āhua i ngā kōpae kē atu i te utu rite. I te mātauranga i te whakamātua i tēnei kōpae ki ōna kaitātai tata, he pai ake te whakamārama i ngā kōrero whakamātua.

He aha ngā rerekētanga o ngā tikanga whakamātua kōpae i waenganui i ngā momo kōpae

Ko ngā kōpae i tātai mua he whakamātautau i te rere o te hāngai, ā, ko te rere o te hāngai e whakamāhi ana i te wā o te hanga, nā reira kāore he hāngai i te pāpātanga o te kaiwhakamahi i te pūhanga hāngai. Ko tēnei rerekētanga he mea matua i ngā taputapu e rere ana tonu. Ko te whakamātautau hāngai i te wai e hiahiatia ana he wāhi takitahi hei whakamāhi i te hāngai, te whakamāhi i ngā wai kaha, me ngā wā whakamātautau, ā, kātahi ka whakauru ai ngā mahinga pānga, me ngā wāhi noho. Ko ngā kōpae BOPP i tātai mua e whakamāhi ana i ngā tāwhai hāngai i waenganui i te 80°C me te 120°C, ā, ko te hāngai e whanake ana i ngā sekone e toru i raro i te pākī, ā, ko ngā kōpae PET i tātai mua e whakamāhi ana i tēnei tikanga anō, engari i ngā tāwhai hāngai ake, i te take o te pārāwaha ake o te PET, ā, ka whakamātau i ngā kōpae e mātua pākoki ana, pērā i ngā pepa iti kāore i te whakamātautau.

Whakawhitinga ō ngā Kōpae Matua

He maha ngā whānau kōpae i te pākanga o ngā kōpae whakamātautau, ā, ko ia whānau he rerekē ngā whāinga. Ko ngā whakawhitinga i raro nei he whakamātautau i ngā whāinga e mātao ana i ngā whakamātautau hāngai, me ngā whakamātautau pakanga.

Ko te whakamāhua o te utu o te BOPP he nui i te whakamātautau māmā, engari he rerekē te uara ina whakamahinga i ngā whakamātautau kaha i muri i te whakamātata. Ko ngā whakamātautau pūmau, ngā whakamātautau pūmau hoki, me ngā wāhi e whakamāhinga ana i ngā huringa hāngā o te hāngā, e whakamāhinga ana i ngā kaihoko ki te PET, ki te nylon hoki, mo te kaha o te whakamātata.

Ngā wāhi e iti ana ngā whakamātautau o te kōpae BOPP i mua i te whakamātata

Ko te whakamātautau pono he whakamātautau i ngā wāhi e iti ana. Kāore te kōpae BOPP i mua i te whakamātata he whakamātautau tika mō ngā whakamātautau e whakamāhinga ana i te whakamātautau o te UV i waho i te wā roa, kāore he whakamātata kia mau, nā te mātua o te polypropylene e whakamāhinga ana i te whakamātata. I tēnei hoki, kāore he pai i ngā whakamātautau e whai ana i te kaha o te hāngā i runga ake i te 100°C, pērā i ngā whakamātautau kai e whakamāhinga ana i ngā whakamātata e whakamāhinga ana i te microwave.

I tēnei te whakamātautau i tēnei: ko tēnei he kaiwhakamāngō pākanga i te tonga o Tāiwhān e whakamahi ana i ngā pouaka koha, i kitea tēnei i tēnei wā i tēnei rōpū o ngā pouaka kaha i hoki mai i tēnei whakamātautau pāpātanga i ngā whakamāngō o te kiri pūrere i ngā tapa kōpae. I tēnei whakamātautau i tātaihia mai i tēnei rerekētanga i waenganui i te whakamātautau o te kiri pūrere me te whakamātautau o te whakamāngō i whakamahinga hei whakamātautau mō te whakamāngō o te tapa kōpae. I whakamāhinga te whakamātautau hou me te kaha o te whakamāngō kia nui ake, ā, i tēnei wā i whakamārama ai te hāngā o te whakamātautau o te whakamāngō me ngā whakamāngō kia rite te whakamātautau ki te momo kiri pūrere anō.

Inā he aha te take e whakamāna ana i te utu mātua mō te Kiri Pūrere PET

Mō ngā tono e tino whakahaeretia ana e te mahi matapihi, ka nui ake te utu o te kiriata PET kua oti te whakakikoruatia. Ko te tohu whakaheke taketake o te PET e whakaputa ana i nga taumata kakara nui ake me te whakamarama atarangi tino pai i roto i nga huinga pepa whakairo. Ko nga kaihoahoa takai papai e mahi ana i runga i nga momo whakapaipai me nga waipiro ka tohu i te PET i runga i te papa o waho mo tenei take. Ko te utu ko te pāmahana tukatuka, e hiahiatia ana kia whakapumautia e taea ana e te paparanga o te laminator me te paera wera te pupuri i te putanga ōrite me te kore e rere te pāmahana.

E ai ki ngā raraunga whakamātautau i whakaputaina e te Flexographic Technical Association, ko ngā inenga o te porohita o te mata (i whanganga i te 60 nekehanga mā ASTM D2457) mō ngā laminates PET-based he 85 ki te 95 GU i whakaritea ki te 70 ki te 80 GU mō ngā kiriata BOPP ō

Te Hōmai i te Whakarite ki te Mahi

Ko te whakautū tātai hei whakautū tātai, he iti ngā wā e tika ana i ngā whakamātautau katoa. Ko te kōpae BOPP kua whakamātua te whakamāhi i te nuinga o ngā mahi whakamātautau hāpaitanga, nā te pānga utu-putanga e tātai ana i te whānuitanga o ngā whakamāhi ā-papa me ngā hāpai whakamātautau. Ka tīkina te PET inā he mea tāwhai tonu te whakamāhi i ngā whakamāhi ā-tiro, i ngā whakamāhi ā-tepō, i ngā whakamāhi ā-hiko. Kei te piki ake ngā whakamāhi kāore i te pāpā, hei whakamāhi mō ngā whakamāhi e tātai ana i te whakamāhi i ngā whakamāhi kia ora tonu, ahakoa ko ngā utu kei te piki ake i tēnei wā, me ngā whakamāhi anō hoki e hiahiatia ana.

I whakamāhi a EKO i tēnei katoa o ngā rākau, mai i te BOPP tātai kua whakamātua ki ngā rākau ā-inkjet me ngā rākau kāore i te pāpā, i te whakamāhi tonu i ngā rākau i te tau e rua tekau nei.
