Ko te kiriata OPP he momo kiriata polypropylene, e kiia ana ko te kiriata polypropylene aronga-whakaputa-tahi (OPP) nā te mea he whakaputa-maha-paparanga te tukanga whakaputa. Mena he tukanga totoro-rua-aronga kei roto i te tukatuka, ka kiia ko te kiriata polypropylene aronga-rua-aronga (BOPP). Ko tētahi atu ka kiia ko te kiriata polypropylene whakarewa (CPP) he rerekē ki te tukanga whakaputa-tahi. He rerekē ngā āhuatanga me ngā whakamahinga o ngā kiriata e toru.
I. Ngā whakamahinga matua o te kiriata OPP
OPP: te polypropylene hāngai (kiriata), te polypropylene hāngai, he momo polypropylene.
Ngā hua matua i hangaia ki te OPP:
1, rīpene OPPkiriata polypropylene hei papa, he kaha te kume, he māmā, he kore paitini, he kore reka, he hoa taiao, he whānui te whakamahinga me ētahi atu painga
2, Ngā tapanga OPP:Nā te mea he tino mātotoru, he ōrite hoki ngā hua o ia rā i te mākete, ko te āhua te mea nui, ko te whakaaro tuatahi te mea e whakatau ana i te whanonga hoko a te kaihoko. Ka whakamahia te hopi horoi, te wai kaukau, te hopi horoi me ētahi atu hua i roto i ngā kaukau me ngā kīhini mahana, makuku hoki, kia ātete te tapanga ki te makuku, kia kore ai e taka, me tōna ātete ki te whakaputanga me te pounamu, ko ngā pounamu mārama he mea whakatakoto i ngā whakaritenga pakari mō te mārama o te piri me ngā rauemi tapanga.
Ki te whakatauritea ki ngā tapanga OPP me ngā tapanga pepa, he mārama, he kaha, he makuku, he ngāwari ki te taka, me ētahi atu painga anō hoki. Ahakoa te pikinga o te utu, ka taea te whakaatu me te whakamahi i ngā tapanga he tino pai. Engari ka taea te whakaatu me te whakamahi i ngā tapanga he tino pai. Nā te whanaketanga o te hangarau tā ā-rohe, te hangarau paninga, te hanga tapanga kiriata piri-ā-roto me ngā tapanga kiriata tā, kāore e raru ana, ka taea te matapae ka piki haere tonu te whakamahinga ā-rohe o ngā tapanga OPP.
I te mea he PP te tapanga, ka taea te hono pai ki te mata o te ipu PP/PE, kua whakamātauhia e te mahi ko te kiriata OPP te rauemi pai rawa atu mō te tapanga i roto i te pokepokea ai, te kai me te ahumahi matū o ia rā i Uropi. He maha ngā tono i puta i reira, ā, kua horapa haere ki te kāinga, kua piki haere te maha o ngā kaiwhakamahi kua tīmata ki te aro ki te tukanga tapanga i roto i te pokepokea ai, ki te whakamahi rānei.
Tuarua, ko te kaupapa matua o te kiriata BOPP
BOPP: Kiriata polypropylene e anga ana ki ngā taha e rua, tētahi momo polypropylene anō hoki.
Ko ngā kiriata BOPP e whakamahia whānuitia ana ko:
● kiriata polypropylene whānui e rua ngā aronga,
● kiriata polypropylene takirua-hāngai hiri-wera,
● kiriata takai hikareti,
● kiriata peara polypropylene e rua-aronga ana,
● kiriata whakarewa polypropylene e rua-aronga ana,
● kiriata matte me ētahi atu.
Ko ngā whakamahinga matua o ngā kiriata rerekē koia ēnei:
1, Kiriata BOPP noa
E whakamahia ana mō te tā, te hanga putea, hei rīpene piri me te honohono ki ētahi atu papa.
2, kiriata hiri wera BOPP
Te nuinga e whakamahia ana mō te tā, te hanga putea me ētahi atu.
3, kiriata takai hikareti BOPP
Whakamahinga: Mō te takai hikareti tere-rahi.
4, kiriata pearized BOPP
Whakamahia mō te takai kai me ngā hua o te whare i muri i te tānga.
5、Kiriata Whakarewa BOPP
Whakamahia hei whakarewa korehau, hei irahiko, hei papa ārai-tinihanga, hei takai kai.
6, kiriata BOPP matte
Whakamahia mō te hopi, te kai, te hikareti, ngā mea whakapaipai, ngā hua rongoā me ētahi atu pouaka takai.
7, kiriata ārai-kohu BOPP
Whakamahia mō te takai i ngā huawhenua, ngā hua rākau, te sushi, ngā putiputi me ērā atu.
He mea tino nui te kiriata BOPP hei rauemi takai ngāwari, ā, he whānuitia te whakamahinga.
Ko te kiriata BOPP he kore tae, kāore he kakara, kāore he reka, kāore he paitini, ā, he kaha kume teitei, he kaha pānga, he pakari, he pakari, he mārama hoki.
He iti te kaha o te mata o te kiriata BOPP, ka taea te whakapiripiri, te tā rānei i mua i te maimoatanga korona. Heoi, he pai te urutau o te kiriata BOPP i muri i te maimoatanga korona, ka taea te tā tae me te whiwhi i te āhua ataahua, nō reira ka whakamahia whānuitia hei rauemi mata kiriata hiato.
He ngoikoretanga anō hoki te kiriata BOPP, pērā i te ngāwari ki te kohikohi hiko pateko, kāore he hiri wera me ērā atu mea. I roto i te raina whakaputa tere-rahi, he ngāwari te kiriata BOPP ki te hiko pateko, me tāuta he tango hiko pateko.
Hei whiwhi i te kiriata BOPP hiri-wera, ka taea te pani i te mata o te kiriata BOPP ki te piri kapia hiri-wera, pērā i te PVDC latex, te EVA latex, me ētahi atu. Ka taea hoki te pani ki te piri whakarewa, engari ka taea hoki te whakamahi i te paninga extrusion, te tikanga laminating co-extrusion rānei hei whakaputa i te kiriata BOPP hiri-wera. He whānuitia te whakamahinga o te kiriata i roto i ngā takai taro, kākahu, hu me ngā tōkena, tae atu ki ngā hikareti, ngā takai uhi pukapuka.
Kua piki ake te kaha o te haehae i muri i te totoro o te kiriata BOPP, engari he iti rawa te kaha o te haehae tuarua, no reira kāore e taea te waiho i te kiriata BOPP ki ngā taha e rua o te mata pito o te koki, ki te kore ka ngawari te haehae o te kiriata BOPP i te wā e tā ana, ka pania.
Ka taea te hanga i te rīpene BOPP kua pania ki te rīpene piri-whaiaro hei hiri i te rīpene pouaka, ko te horopeta BOPP ka taea te hanga rīpene hiri BOPP kua pania ki te rīpene piri-whaiaro, ko te whakamahinga BOPP o te mākete whānui.
Ka taea te hanga kiriata BOPP mā te tikanga kiriata ngongo, mā te tikanga kiriata papatahi rānei. He rerekē ngā āhuatanga o ngā kiriata BOPP i whiwhihia mā ngā tikanga tukatuka rerekē. Nā te ōwehenga kume nui (tae atu ki te 8-10) i hanga ai te kiriata BOPP mā te tikanga kiriata papatahi, nō reira he teitei ake te kaha i te tikanga kiriata ngongo, ā, he pai ake te ōritetanga o te matotoru o te kiriata.
Hei whakatutuki i te mahi whānui pai ake, i roto i te whakamahinga o te tukanga e whakamahia ana i roto i te hanga i te tikanga hiato maha-paparanga. Ka taea te whakakotahi i te BOPP me ngā momo rauemi rerekē hei whakatutuki i ngā hiahia o ngā tono motuhake. Pērā i te BOPP ka taea te whakakotahi me te LDPE (CPP), PE, PT, PO, PVA, me ētahi atu. Hei whakatutuki i te taumata teitei o te arai hau, te arai makuku, te mārama, te ātete pāmahana teitei me te iti, te ātete tunu kai me te ātete hinu, ka taea te whakamahi i ngā kiriata hiato rerekē ki ngā kai hinuhinu.
Tuatoru, ko te kaupapa matua o te kiriata CPP
CPP: he mārama pai, he kanapa teitei, he pakari pai, he ārai makuku pai, he ātete wera pai, he ngāwari ki te hiri i te wera me ērā atu.
Kiriata CPP i muri i te tānga, te hanga putea, he pai mō: ngā putea kakahu, whatu me ngā putiputi; kiriata tuhinga me ngā pukaemi; takai kai; me te mō te takai arai me te kiriata whakarewa whakapaipai.
Ko ētahi atu whakamahinga pea ko: te takai kai, te takai monamona (kiriata miro), te takai rongoā (pēke whaowhia), te whakakapi i te PVC i roto i ngā puka whakaahua, ngā kōpaki me ngā tuhinga, te pepa hangai, ngā rīpene piri-ake, ngā kaipupuri kāri pakihi, ngā here mowhiti me ngā putea tū-ake.
He tino pai te ātete wera o te CPP.
I te mea ko te pūwāhi whakangawari o te PP e tata ana ki te 140°C, ka taea te whakamahi i tēnei momo kiriata ki ngā wāhi pēnei i te whakakī wera, ngā putea korohū me te takai ātete.
He pai rawa atu hoki tōna ātete ki te waikawa, te kawakore me te hinu, ā, koinei te rauemi pai rawa atu mō ngā mahi pēnei i te takai taro, ngā rauemi whakakikoruatia rānei.
He pai te āhua o te haumaru ki te pa atu ki ngā kai, ā, he pai te whakaaturanga, kāore e pā ki te reka o te kai i roto, ā, ka taea te whiriwhiri i ngā momo kāpia rerekē hei whakatutuki i ngā āhuatanga e hiahiatia ana.
