Kanema wa OPP ndi mtundu wa filimu ya polypropylene, yomwe imatchedwa filimu ya co-extruded oriented polypropylene (OPP) chifukwa kachitidwe kake kamakhala ndi multilayer extrusion. Ngati pali njira yotambasulira yozungulira pokonza, imatchedwa bi-directional oriented polypropylene film (BOPP). Zina zimatchedwa filimu ya polypropylene (CPP) mosiyana ndi njira yolumikizirana. Mafilimu atatuwa amasiyana malinga ndi momwe amagwiritsira ntchito.
I. Ntchito zazikulu za filimu ya OPP
OPP: oriented polypropylene (filimu), oriented polypropylene, ndi mtundu umodzi wa polypropylene.
Zogulitsa zazikulu zopangidwa ndi OPP:
1, OPP tepi: filimu ya polypropylene ngati gawo lapansi, yokhala ndi mphamvu zolimba kwambiri, zopepuka, zopanda poizoni, zopanda pake, zachilengedwe, zogwiritsa ntchito zosiyanasiyana ndi zabwino zina
2, zolemba za OPP:chifukwa msika umakhala wodzaza ndi zinthu zatsiku ndi tsiku, mawonekedwe ndi chilichonse, mawonekedwe oyamba amatsimikizira zomwe wogula amagula. Shampoo, gel osamba, zotsukira ndi zinthu zina zimagwiritsidwa ntchito m'zipinda zosambira zotentha ndi zonyowa ndi khitchini, zofunikira za chizindikirocho kuti zipirire chinyezi komanso sizikugwa, komanso kukana kwake kutulutsa kuyenera kugwirizana ndi botolo, pomwe mabotolo owonekera Kuwonekera kwa zomatira ndi zolembera kumapereka zofunika kwambiri.
Zolemba za OPP zokhudzana ndi zolemba zamapepala, zowonekera bwino, mphamvu zambiri, chinyezi, zosavuta kugwa ndi ubwino wina, ngakhale kuti mtengowo ukuwonjezeka, koma ukhoza kupeza mawonedwe abwino kwambiri ndi ntchito. Koma mutha kupeza mawonekedwe abwino kwambiri a zilembo ndikugwiritsa ntchito. Ndi chitukuko cha teknoloji yosindikizira m'nyumba, teknoloji yokutira, kupanga zolemba za mafilimu odziphatika ndi zosindikizira mafilimu sikulinso vuto, zikhoza kunenedweratu kuti ntchito zapakhomo za zolemba za OPP zidzapitirira kuwonjezeka.
Monga chizindikiro palokha ndi PP, akhoza bwino pamodzi ndi PP / PE chidebe pamwamba, mchitidwe watsimikizira kuti OPP filimu panopa zinthu zabwino mu nkhungu kulemba, chakudya ndi tsiku makampani mankhwala ku Ulaya wakhala chiwerengero chachikulu cha ntchito, ndipo pang'onopang'ono kufalikira kwa zoweta, pali owerenga ambiri anayamba kulabadira kapena ntchito mu nkhungu kulemba ndondomeko.
Chachiwiri, cholinga chachikulu cha filimu ya BOPP
BOPP: Kanema wa polypropylene wa Biaxially, komanso mtundu umodzi wa polypropylene.
Makanema omwe amagwiritsidwa ntchito kwambiri a BOPP ndi awa:
● filimu ya polypropylene yokhazikika kwambiri,
● filimu ya polypropylene yotsekedwa ndi kutentha,
● filimu yonyamula ndudu,
● filimu ya pearlescent ya bi-oriented polypropylene,
● filimu yopangidwa ndi zitsulo zopangidwa ndi polypropylene,
● filimu ya matte ndi zina zotero.
Ntchito zazikulu zamakanema osiyanasiyana ndi izi:
1, Kanema wamba wa BOPP
Amagwiritsidwa ntchito makamaka kusindikiza, kupanga thumba, ngati tepi yomatira komanso kuphatikiza ndi magawo ena.
2, BOPP kutentha kusindikiza filimu
Amagwiritsidwa ntchito makamaka kusindikiza, kupanga thumba ndi zina zotero.
3, filimu yonyamula ndudu ya BOPP
Ntchito: Amagwiritsidwa ntchito polongedza ndudu zothamanga kwambiri.
4, filimu yodziwika bwino ya BOPP
Amagwiritsidwa ntchito ngati chakudya ndi zopangira zapakhomo pambuyo posindikiza.
5, BOPP Metalized Film
Amagwiritsidwa ntchito ngati vacuum metallization, radiation, anti-counterfeiting gawo lapansi, ma CD a chakudya.
6, BOPP matte filimu
Amagwiritsidwa ntchito ngati sopo, chakudya, ndudu, zodzoladzola, mankhwala ndi mabokosi ena oyikamo.
7, filimu yotsutsa chifunga ya BOPP
Amagwiritsidwa ntchito kunyamula masamba, zipatso, sushi, maluwa ndi zina zotero.
Kanema wa BOPP ndichinthu chofunikira kwambiri chosinthira, chomwe chimagwiritsidwa ntchito kwambiri.
Kanema wa BOPP wopanda utoto, wopanda fungo, wosakoma, wopanda poizoni, ndipo ali ndi mphamvu zolimba kwambiri, kulimba, kulimba, kulimba komanso kuwonekera bwino.
Mphamvu zamakanema a BOPP ndizotsika, zomatira kapena zosindikiza musanalandire chithandizo cha corona. Komabe, filimu ya BOPP pambuyo pa chithandizo cha corona, imakhala ndi kusinthika kwabwino kosindikiza, imatha kusindikiza mitundu ndikuwoneka bwino, motero imagwiritsidwa ntchito ngati filimu yophatikizika pamwamba.
Filimu ya BOPP imakhalanso ndi zofooka, monga zosavuta kusonkhanitsa magetsi osasunthika, palibe kusindikiza kutentha ndi zina zotero. Mumzere wothamanga kwambiri, filimu ya BOPP imakonda kukhala ndi magetsi osasunthika, imayenera kukhazikitsa chochotsera magetsi.
Kuti mupeze filimu ya BOPP yotsekedwa ndi kutentha, chithandizo cha filimu ya BOPP pamwamba pa korona chikhoza kuphimbidwa ndi zomatira zomata zotsekedwa ndi kutentha, monga PVDC latex, EVA latex, etc. -extrusion laminating njira angagwiritsidwe ntchito kupanga kutentha-sealable BOPP film. Firimuyi imagwiritsidwa ntchito kwambiri mu mkate, zovala, nsapato ndi masokosi, komanso ndudu, mabuku ophimba mabuku.
Kuyambitsa filimu ya BOPP ya mphamvu ya misozi pambuyo pa kutambasula kwawonjezeka, koma mphamvu yachiwiri ya misozi ndiyotsika kwambiri, kotero kuti filimu ya BOPP silingasiyidwe kumbali zonse za mapeto a notch, mwinamwake filimu ya BOPP ndiyosavuta kung'amba kusindikiza. , laminating.
BOPP yokutidwa ndi tepi yodzimatira imatha kupangidwa kuti isindikize tepi ya bokosi, ndiye mlingo wa BOPP wodzimatira wa BOPP wodzimatira ukhoza kupanga tepi yosindikiza, ndiye kugwiritsa ntchito kwa BOPP pamsika waukulu.
Makanema a BOPP amatha kupangidwa ndi njira ya filimu ya chubu kapena njira ya filimu yosalala. Mawonekedwe a makanema a BOPP omwe amapezedwa ndi njira zosiyanasiyana zopangira ndi zosiyana. Kanema wa BOPP wopangidwa ndi njira ya filimu yosalala chifukwa cha chiwopsezo chachikulu (mpaka 8-10), ndiye kuti mphamvu ndi yayikulu kuposa njira ya filimu ya chubu, makulidwe a filimuyo ndi abwinoko.
Pofuna kupeza ntchito yabwino kwambiri, pogwiritsira ntchito ndondomekoyi nthawi zambiri amagwiritsidwa ntchito popanga njira zophatikizira zamitundu yambiri.BOPP ikhoza kuphatikizidwa ndi zipangizo zosiyanasiyana kuti zigwirizane ndi zosowa zapadera. Monga BOPP imatha kuphatikizidwa ndi LDPE (CPP), PE, PT, PO, PVA, ndi zina zambiri kuti mupeze chotchinga chachikulu cha gasi, chotchinga chinyezi, kuwonekera, kukana kutentha kwambiri komanso kutsika, kukana kuphika ndi kukana mafuta, kuphatikiza kosiyanasiyana. mafilimu angagwiritsidwe ntchito pa zakudya zamafuta.
Chachitatu, cholinga chachikulu cha filimu ya CPP
CPP: kuwonekera bwino, gloss mkulu, kuuma bwino, chotchinga chinyezi chabwino, kukana kutentha kwambiri, kusindikiza kosavuta kutentha ndi zina zotero.
Kanema wa CPP pambuyo pa kusindikiza, kupanga thumba, koyenera: zovala, knitwear ndi matumba a maluwa; zikalata ndi Albums filimu; kuyika chakudya; ndi chotchinga ma CD ndi kukongoletsa filimu metallized.
Zomwe zitha kugwiritsidwa ntchito zikuphatikizanso: kuphimba chakudya, chowonjezera cha confectionery (filimu yopotoka), zopaka zamankhwala (matumba olowetsedwa), m'malo mwa PVC mu Albums zazithunzi, zikwatu ndi zikalata, mapepala opangira, matepi odzimatira, zosunga makhadi abizinesi, zomangira mphete ndi kuyimilira. ma composite.
CPP ili ndi kukana kwambiri kutentha.
Popeza kufewetsa kwa PP kuli pafupi ndi 140 ° C, filimu yamtunduwu ingagwiritsidwe ntchito m'madera monga kudzaza kutentha, matumba a steaming ndi aseptic phukusi.
Kuphatikizidwa ndi asidi wabwino kwambiri, alkali ndi kukana mafuta, kumapangitsa kukhala chinthu chosankha m'malo monga zopangira mkate kapena zida zam'madzi.
Chitetezo chake chokhudzana ndi chakudya, machitidwe abwino owonetsera, sichingakhudze kukoma kwa chakudya mkati, ndipo amatha kusankha mitundu yosiyanasiyana ya utomoni kuti apeze zomwe mukufuna.
