Filimu ya OPP ndi mtundu wa filimu ya polypropylene, yomwe imatchedwa filimu ya co-extruded oriented polypropylene (OPP) chifukwa njira yopangira ndi multi-layer extrusion. Ngati pali njira yotambasula mbali ziwiri pokonza, imatchedwa bi-directional oriented polypropylene film (BOPP). Wina umatchedwa cast polypropylene film (CPP) mosiyana ndi njira ya co-extrusion. Mafilimu atatuwa amasiyana malinga ndi momwe amagwiritsidwira ntchito komanso momwe amagwiritsidwira ntchito.
I. Ntchito zazikulu za filimu ya OPP
OPP: polypropylene yolunjika (filimu), polypropylene yolunjika, ndi mtundu umodzi wa polypropylene.
Zinthu zazikulu zopangidwa ndi OPP:
1, tepi ya OPP: filimu ya polypropylene ngati substrate, yokhala ndi mphamvu yokoka kwambiri, yopepuka, yopanda poizoni, yopanda kukoma, yosamalira chilengedwe, yogwiritsidwa ntchito mosiyanasiyana komanso zabwino zina
2, zilembo za OPP:Popeza msika uli ndi zinthu zodzaza tsiku ndi tsiku komanso zofanana, mawonekedwe ake ndi ofunika kwambiri, lingaliro loyamba limatsimikiza khalidwe la ogula pogula. Shampoo, shawa gel, sopo ndi zinthu zina zimagwiritsidwa ntchito m'zimbudzi zofunda komanso zonyowa, zofunikira za chizindikirocho kuti zipirire chinyezi ndipo sizigwa, ndipo kukana kwake kutuluka kuyenera kufananizidwa ndi botolo, pomwe mabotolo owonekera bwino kuti guluu ndi zinthu zolembera ziwonekere bwino zimayika zofunikira kwambiri.
Zolemba za OPP poyerekeza ndi zilembo zamapepala, zowonekera bwino, zolimba kwambiri, chinyezi, zosavuta kugwa ndi zabwino zina, ngakhale mtengo wake ukukwera, koma zimatha kuwonetsa bwino kwambiri zilembo ndikugwiritsa ntchito. Koma zimatha kuwonetsa bwino kwambiri zilembo ndikugwiritsa ntchito. Ndi chitukuko cha ukadaulo wosindikiza m'nyumba, ukadaulo wokutira, kupanga zilembo zamakanema zodzimatira ndi zilembo zamakanema zosindikizira sikulinso vuto, zitha kunenedweratu kuti kugwiritsa ntchito zilembo za OPP m'nyumba kudzapitirira kuwonjezeka.
Popeza chizindikirocho ndi PP, chikhoza kuphatikizidwa bwino ndi pamwamba pa chidebe cha PP/PE, machitidwe atsimikizira kuti filimu ya OPP pakadali pano ndi chinthu chabwino kwambiri cholembera mu nkhungu, chakudya ndi makampani opanga mankhwala tsiku ndi tsiku ku Europe akhala akugwiritsa ntchito ntchito zambiri, ndipo pang'onopang'ono kufalikira kumayiko akunja, pali ogwiritsa ntchito ambiri omwe adayamba kulabadira kapena kugwiritsa ntchito njira yolembera mu nkhungu.
Chachiwiri, cholinga chachikulu cha filimu ya BOPP
BOPP: Filimu ya polypropylene yolunjika mbali imodzi, komanso mtundu umodzi wa polypropylene.
Mafilimu a BOPP omwe amagwiritsidwa ntchito kwambiri ndi awa:
● filimu ya polypropylene yozungulira mbali zonse ziwiri,
● filimu ya polypropylene yozungulira kawiri yotsekedwa ndi kutentha,
● filimu yopaka ndudu,
● filimu ya polypropylene ya pearlescent yokhala ndi mbali ziwiri,
● filimu ya polypropylene yozungulira kawiri,
● filimu yosaoneka bwino ndi zina zotero.
Kugwiritsa ntchito kwakukulu kwa mafilimu osiyanasiyana ndi awa:
1, filimu ya BOPP yachizolowezi
Amagwiritsidwa ntchito makamaka posindikiza, kupanga matumba, ngati tepi yomatira komanso kuphatikiza ndi zinthu zina.
2, BOPP kutentha kusindikiza filimu
Amagwiritsidwa ntchito makamaka posindikiza, kupanga matumba ndi zina zotero.
3, filimu yopaka ndudu ya BOPP
Kugwiritsa Ntchito: Kumagwiritsidwa ntchito popangira ndudu zachangu kwambiri.
4, filimu ya BOPP yopangidwa ndi ngale
Amagwiritsidwa ntchito popangira chakudya ndi zinthu zapakhomo pambuyo posindikiza.
5, Filimu ya Bopp Metallized
Amagwiritsidwa ntchito ngati vacuum metallization, radiation, anti-counterfeiting substrate, ndi ma CD a chakudya.
6, filimu ya BOPP matte
Amagwiritsidwa ntchito pa sopo, chakudya, ndudu, zodzoladzola, mankhwala ndi mabokosi ena olongedza.
7, filimu yotsutsana ndi chifunga ya BOPP
Amagwiritsidwa ntchito popaka ndiwo zamasamba, zipatso, sushi, maluwa ndi zina zotero.
Filimu ya BOPP ndi zinthu zofunika kwambiri zosungiramo zinthu zosinthika, zomwe zimagwiritsidwa ntchito kwambiri.
Filimu ya BOPP ndi yopanda utoto, yopanda fungo, yopanda kukoma, yopanda poizoni, ndipo imakhala ndi mphamvu yokoka, mphamvu yokoka, kulimba, komanso yowonekera bwino.
Mphamvu ya pamwamba pa filimu ya BOPP ndi yochepa, ngati pali guluu kapena kusindikiza isanayambe chithandizo cha corona. Komabe, filimu ya BOPP ikatha chithandizo cha corona, imatha kusinthidwa bwino, imatha kusindikizidwa ndi utoto ndikuwoneka bwino, motero imagwiritsidwa ntchito kwambiri ngati zinthu zopangira filimu yophatikizana.
Filimu ya BOPP ilinso ndi zofooka, monga kusonkhanitsa mosavuta magetsi osasunthika, palibe kutseka kutentha ndi zina zotero. Mu mzere wopanga mwachangu, filimu ya BOPP imakonda magetsi osasunthika, ndipo muyenera kuyika chochotsera magetsi osasunthika.
Kuti mupeze filimu ya BOPP yotsekedwa ndi kutentha, chithandizo cha korona cha filimu ya BOPP pamwamba pa korona chikhoza kuphimbidwa ndi guluu wa resin wotsekedwa ndi kutentha, monga PVDC latex, EVA latex, ndi zina zotero, chikhoza kuphimbidwanso ndi guluu wosungunulira, komanso njira yotulutsira extrusion kapena co-extrusion laminating ingagwiritsidwe ntchito popanga filimu ya BOPP yotsekedwa ndi kutentha. Filimuyi imagwiritsidwa ntchito kwambiri mu buledi, zovala, nsapato ndi masokosi, komanso ndudu, mabuku ophimba.
Kuyamba kwa mphamvu ya misozi mu filimu ya BOPP pambuyo potambasula kwawonjezeka, koma mphamvu ya misozi yachiwiri ndi yochepa kwambiri, kotero filimu ya BOPP siingasiyidwe mbali zonse ziwiri za kumapeto kwa notch, apo ayi filimu ya BOPP ndi yosavuta kung'ambika mu kusindikiza, ndikuyika laminating.
Bopp yokutidwa ndi tepi yodzimatira yokha imatha kupangidwa kuti isindikize tepi ya bokosi, ndipo mlingo wa BOPP womwe BOPP yokutidwa ndi zomatira yokha imatha kupanga tepi yomatira, ndiye kuti BOPP imagwiritsidwa ntchito kwambiri pamsika waukulu.
Makanema a BOPP amatha kupangidwa pogwiritsa ntchito njira ya chubu kapena njira ya flat film. Kapangidwe ka mafilimu a BOPP omwe amapezeka pogwiritsa ntchito njira zosiyanasiyana zokonzera ndi kosiyana. Kanema wa BOPP wopangidwa pogwiritsa ntchito njira ya flat film chifukwa cha chiŵerengero chachikulu cha ma tensile (mpaka 8-10), kotero mphamvu yake ndi yayikulu kuposa njira ya chubu, kufanana kwa makulidwe a filimuyi nakonso kuli bwino.
Kuti zinthu ziyende bwino, njira yogwiritsira ntchito nthawi zambiri imagwiritsidwa ntchito popanga zinthu zosiyanasiyana. BOPP imatha kuwonjezeredwa ndi zinthu zosiyanasiyana kuti ikwaniritse zosowa za ntchito zapadera. Monga BOPP, imatha kuwonjezeredwa ndi LDPE (CPP), PE, PT, PO, PVA, ndi zina zotero kuti ipeze chotchinga cha mpweya, chotchinga chinyezi, kuwonekera bwino, kukana kutentha kwambiri komanso kotsika, kukana kuphika komanso kukana mafuta, mafilimu osiyanasiyana ophatikizika amatha kugwiritsidwa ntchito pazakudya zamafuta.
Chachitatu, cholinga chachikulu cha filimu ya CPP
CPP: kuwonekera bwino, kunyezimira kwambiri, kuuma bwino, chotchinga chinyezi chabwino, kukana kutentha bwino, kutseka kutentha kosavuta ndi zina zotero.
Filimu ya CPP ikatha kusindikizidwa, kupanga matumba, yoyenera: zovala, matumba oluka ndi maluwa; mapepala ndi ma Albums filimu; ma CD a chakudya; komanso ma CD otchinga ndi filimu yokongoletsera yachitsulo.
Ntchito zomwe zingagwiritsidwe ntchito zikuphatikizapo: kuphimba chakudya, kuphimba makeke (filimu yopotoka), kuyika mankhwala (matumba olowetsera), kusintha PVC m'ma Albums a zithunzi, mafoda ndi zikalata, mapepala opangidwa, matepi odzimatira okha, zogwirira makadi a bizinesi, zomangira mphete ndi zomangira matumba oimika.
CPP ili ndi kukana kutentha kwambiri.
Popeza malo ofewa a PP ndi pafupifupi 140°C, mtundu uwu wa filimu ungagwiritsidwe ntchito m'malo monga kudzaza ndi kutentha, matumba otenthetsera ndi kuyikapo zinthu zopanda poizoni.
Kuphatikiza pa kukana asidi, alkali ndi mafuta bwino, zimapangitsa kuti ikhale chinthu chosankhidwa kwambiri m'malo monga ma CD a buledi kapena zinthu zopakidwa laminated.
Chitetezo chake pa kukhudzana ndi chakudya, mawonekedwe ake abwino kwambiri, sichidzakhudza kukoma kwa chakudya mkati, ndipo chingasankhe mitundu yosiyanasiyana ya utomoni kuti chipeze mawonekedwe omwe mukufuna.
