ʻO ka ʻili OPP kahi ʻano ʻili polypropylene, i kapa ʻia ʻo co-extruded oriented polypropylene (OPP) film no ka mea ʻo ke kaʻina hana he multi-layer extrusion. Inā he kaʻina hana hoʻolōʻihi bi-directional i ka hana ʻana, ua kapa ʻia ʻo bi-directional oriented polypropylene film (BOPP). ʻO kekahi ua kapa ʻia ʻo cast polypropylene film (CPP) i kūʻē i ke kaʻina hana co-extrusion. ʻOkoʻa nā ʻili ʻekolu i ko lākou mau waiwai a me nā hoʻohana.
I. Nā hoʻohana nui o ka ʻili OPP
OPP: polypropylene i kuhikuhi ʻia (kiʻiʻoniʻoni), polypropylene i kuhikuhi ʻia, ʻo ia kekahi ʻano polypropylene.
Nā huahana nui i hana ʻia me OPP:
1, lipine OPPʻO ka kiʻiʻoniʻoni polypropylene ma ke ʻano he substrate, me ka ikaika tensile kiʻekiʻe, māmā, ʻaʻohe ʻawaʻawa, ʻono ʻole, pili i ke kaiapuni, ākea ka hoʻohana ʻana a me nā pono ʻē aʻe
2, nā lepili OPP:No ka mea, ua piha ka mākeke i nā huahana o kēlā me kēia lā a ua like ka ʻano, ʻo ke ʻano ka mea nui, ʻo ka manaʻo mua ke kumu o ke kūʻai ʻana o ka mea kūʻai. Hoʻohana ʻia ka shampoo, ka gel ʻauʻau, nā detergents a me nā huahana ʻē aʻe i loko o nā lumi ʻauʻau a me nā lumi kuke mehana a pulu, ʻo nā koi o ka lepili e kū i ka makū a ʻaʻole e hāʻule, a ʻo kona kūʻē ʻana i ka extrusion e pono e kūlike me ka ʻōmole, ʻoiai ʻo nā ʻōmole moakaka no ka moakaka o nā mea hoʻopili a me nā lepili e kau i nā koi koʻikoʻi.
ʻO nā lepili OPP e pili ana i nā lepili pepa, me ka moakaka, ka ikaika kiʻekiʻe, ka makū, ʻaʻole maʻalahi e hāʻule a me nā pono ʻē aʻe, ʻoiai ke piʻi nei ke kumukūʻai, akā hiki ke loaʻa kahi hōʻike lepili a me ka hopena hoʻohana maikaʻi loa. Akā hiki ke loaʻa kahi hōʻike lepili a me ka hopena hoʻohana maikaʻi loa. Me ka hoʻomohala ʻana o ka ʻenehana paʻi kūloko, ʻenehana uhi, ka hana ʻana o nā lepili kiʻiʻoniʻoni hoʻopili ponoʻī a me nā lepili kiʻiʻoniʻoni paʻi ʻaʻole ia he pilikia hou, hiki ke wānana ʻia e hoʻomau ka hoʻonui ʻana o ka hoʻohana kūloko o nā lepili OPP.
ʻOiai ʻo ka lepili ponoʻī he PP, hiki ke hoʻohui maikaʻi ʻia me ka ʻili o ka ipu PP/PE, ua hōʻoia ka hana ʻana ʻo ka kiʻiʻoniʻoni OPP i kēia manawa ka mea maikaʻi loa no ka lepili ʻana i loko o ka mold, ʻo ka ʻoihana meaʻai a me nā kemika o kēlā me kēia lā ma ʻEulopa ua nui nā noi, a ua pālahalaha mālie i ka home, a ua hoʻomaka ka nui o nā mea hoʻohana e hoʻolohe a hoʻohana paha i ke kaʻina lepili ʻana i loko o ka mold.
ʻO ka lua, ke kumu nui o ke kiʻiʻoniʻoni BOPP
BOPP: ʻO ke kiʻiʻoniʻoni polypropylene i hoʻonohonoho ʻia i ka biaxially, hoʻokahi ʻano polypropylene hoʻi.
ʻO nā kiʻiʻoniʻoni BOPP i hoʻohana pinepine ʻia:
● ʻili polypropylene bi-oriented maʻamau,
● ʻili polypropylene bi-oriented i hoʻopaʻa ʻia i ka wela,
● ʻili ʻili ʻōpala cigarette,
● ʻiliʻili pearlescent polypropylene bi-oriented,
● ʻiliʻili metala polypropylene bi-oriented,
● kiʻiʻoniʻoni matte a pēlā aku.
ʻO nā hoʻohana nui o nā kiʻiʻoniʻoni like ʻole penei:
1, ʻO ke kiʻiʻoniʻoni BOPP maʻamau
Hoʻohana nui ʻia no ka paʻi ʻana, ka hana ʻana i nā ʻeke, e like me ka lipine hoʻopili a me ka hui pū ʻana me nā substrates ʻē aʻe.
2, ʻoniʻoni sila wela BOPP
Hoʻohana nui ʻia no ka paʻi ʻana, ka hana ʻeke a pēlā aku.
3, ʻili ʻili BOPP
Hoʻohana: Hoʻohana ʻia no ka hoʻopili ʻana i ka cigarette wikiwiki.
4, ʻoniʻoni momi BOPP
Hoʻohana ʻia no ka hoʻopili ʻana i ka meaʻai a me nā huahana home ma hope o ka paʻi ʻana.
5、Kiʻiʻoniʻoni Metallized BOPP
Hoʻohana ʻia e like me ka metallization vacuum, radiation, substrate anti-counterfeiting, packaging food.
6, ʻiliʻili matte BOPP
Hoʻohana ʻia no ke kopa, ka meaʻai, nā cigarette, nā mea hoʻonani, nā huahana lāʻau lapaʻau a me nā pahu hoʻopili ʻē aʻe.
7, ʻoniʻoni anti-noe BOPP
Hoʻohana ʻia no ka hoʻopili ʻana i nā mea kanu, nā huaʻai, nā sushi, nā pua a pēlā aku.
ʻO ka kiʻiʻoniʻoni BOPP kahi mea hoʻopili palupalu koʻikoʻi loa, hoʻohana nui ʻia.
ʻAʻohe kala o ka kiʻiʻoniʻoni BOPP, ʻaʻohe ʻala, ʻono ʻole, ʻaʻohe ʻawahia, a he ikaika tensile kiʻekiʻe, ikaika hopena, paʻakikī, paʻakikī a me ka transparency maikaʻi.
He haʻahaʻa ka ikehu ʻili o ka kiʻiʻoniʻoni BOPP, no laila e hoʻopili a paʻi paha ma mua o ka mālama ʻana i ka corona. Eia nō naʻe, ʻo ka kiʻiʻoniʻoni BOPP ma hope o ka mālama ʻana i ka corona, he maikaʻi ke hoʻololi ʻana i ka paʻi ʻana, hiki ke paʻi kala a loaʻa i kahi hiʻohiʻona nani, a no laila e hoʻohana pinepine ʻia e like me ka mea ʻili kiʻiʻoniʻoni hui pū ʻia.
He mau hemahema nō hoʻi ka kiʻiʻoniʻoni BOPP, e like me ka maʻalahi o ka hōʻiliʻili ʻana i ka uila static, ʻaʻohe sila wela a pēlā aku. I ka laina hana wikiwiki, ua maʻalahi ka kiʻiʻoniʻoni BOPP i ka uila static, pono e hoʻokomo i ka mea wehe uila static.
I mea e loaʻa ai ka kiʻiʻoniʻoni BOPP hiki ke hoʻopaʻa wela ʻia, hiki ke uhi ʻia ka mālama ʻana i ka ʻili corona o ka kiʻiʻoniʻoni BOPP me ka mea hoʻopili resin hiki ke hoʻopaʻa wela ʻia, e like me ka PVDC latex, EVA latex, a pēlā aku. Hiki ke uhi ʻia me ka mea hoʻopili solvent, akā hiki ke hoʻohana ʻia ke ʻano extrusion coating a i ʻole co-extrusion laminating e hana i ka kiʻiʻoniʻoni BOPP hiki ke hoʻopaʻa wela ʻia. Hoʻohana nui ʻia ka kiʻiʻoniʻoni i ka berena, nā lole, nā kāmaʻa a me nā ʻūpā socks, a me nā cigarettes, nā ʻūpā uhi puke.
Ua hoʻonui ʻia ka ikaika haehae o ka hoʻomaka ʻana o ka kiʻiʻoniʻoni BOPP ma hope o ke kīkoʻo ʻana, akā ua haʻahaʻa loa ka ikaika haehae lua, no laila ʻaʻole hiki ke waiho ʻia ke kiʻiʻoniʻoni BOPP ma nā ʻaoʻao ʻelua o ka maka hope o ka notch, inā ʻaʻole e maʻalahi ka haehae ʻana o ke kiʻiʻoniʻoni BOPP i ka wā paʻi, laminating.
Hiki ke hana ʻia ka BOPP i uhi ʻia me ka lipine hoʻopili ponoʻī e sila i ka lipine pahu, ʻo ia ka dosage BOPP hiki i ka BOPP i uhi ʻia me ka hoʻopili ponoʻī ke hana i ka lipine hoʻopaʻa, ʻo ia ka hoʻohana ʻana o ka BOPP i ka mākeke nui.
Hiki ke hana ʻia nā kiʻiʻoniʻoni BOPP ma ke ʻano kiʻiʻoniʻoni paipu a i ʻole ke ʻano kiʻiʻoniʻoni pālahalaha. ʻOkoʻa nā waiwai o nā kiʻiʻoniʻoni BOPP i loaʻa ma o nā ʻano hana like ʻole. ʻO ke kiʻiʻoniʻoni BOPP i hana ʻia e ke ʻano kiʻiʻoniʻoni pālahalaha ma muli o ka lakio tensile nui (a hiki i ka 8-10), no laila ʻoi aku ka ikaika ma mua o ke ʻano kiʻiʻoniʻoni paipu, ʻoi aku ka maikaʻi o ka like ʻana o ka mānoanoa o ke kiʻiʻoniʻoni.
I mea e loaʻa ai kahi hana holoʻokoʻa ʻoi aku ka maikaʻi, i ka hoʻohana ʻana i ke kaʻina hana e hoʻohana pinepine ʻia i ka hana ʻana o ke ʻano hui multi-layer. Hiki ke hoʻohui ʻia ʻo BOPP me nā ʻano mea like ʻole e hoʻokō ai i nā pono o nā noi kūikawā. E like me ka BOPP hiki ke hoʻohui ʻia me LDPE (CPP), PE, PT, PO, PVA, a pēlā aku e loaʻa ai ke kiʻekiʻe o ka pale kinoea, ka pale makū, ka transparency, ke kū'ē ʻana i ke kiʻekiʻe a me ka haʻahaʻa o ka mahana, ke kū'ē ʻana i ka kuke ʻana a me ke kū'ē ʻana i ka aila, hiki ke hoʻopili ʻia nā kiʻiʻoniʻoni hui like ʻole i ka meaʻai ʻaila.
ʻO ke kolu, ke kumu nui o ke kiʻiʻoniʻoni CPP
CPP: ʻike maikaʻi, ʻōlinolino kiʻekiʻe, ʻoʻoleʻa maikaʻi, pale makū maikaʻi, kūpaʻa wela maikaʻi loa, maʻalahi ke sila wela a pēlā aku.
ʻO ka kiʻiʻoniʻoni CPP ma hope o ka paʻi ʻana, ka hana ʻana i nā ʻeke, kūpono no: nā lole, nā lole ulana a me nā ʻeke pua; nā kiʻiʻoniʻoni palapala a me nā album; nā ʻōpala meaʻai; a no ka ʻōpala pale a me ke kiʻiʻoniʻoni metala hoʻonaninani.
ʻO nā hoʻohana kūpono e komo pū ana me: ka uhi ʻana i ka meaʻai, ka uhi ʻana i nā mea ʻono (ʻili wili ʻia), ka ʻōpala lāʻau lapaʻau (ʻeke infusion), ke pani ʻana i ka PVC i nā album kiʻi, nā waihona a me nā palapala, ka pepa synthetic, nā lipine hoʻopili ponoʻī, nā mea paʻa kāleka ʻoihana, nā mea hoʻopaʻa apo a me nā composites ʻeke kū.
He kūpaʻa wela maikaʻi loa ko CPP.
ʻOiai ʻo ke kiko palupalu o PP ma kahi o 140°C, hiki ke hoʻohana ʻia kēia ʻano ʻiliʻili ma nā wahi e like me ka hoʻopiha wela, nā ʻeke mahu a me ka hoʻopili aseptic.
I hui pū ʻia me ke kūpaʻa maikaʻi loa i ka waikawa, alkali a me ka momona, ʻo ia ka mea i koho ʻia ma nā wahi e like me ka ʻōpala huahana berena a i ʻole nā mea laminated.
ʻO kona palekana hoʻopili meaʻai, hana hōʻike maikaʻi loa, ʻaʻole ia e hoʻopilikia i ka ʻono o ka meaʻai i loko, a hiki ke koho i nā ʻano resin like ʻole e loaʻa ai nā ʻano i makemake ʻia.
