Pambuyo pakuwunikidwa kwamakanema a BOPP, kodi mumamvetsetsa movutikira zazinthu zomwe zapezeka paliponse? Mubulogu iyi, tikulitsa chidziwitso chathu pazabwino ndi zoyipa zake, motero timayang'ana bwino zosowa za ogula.
Kodi BOPP Film ndi chiyani
Kanema wa Biaxially Oriented Polypropylene (BOPP) wasintha kwambiri ntchito yonyamula katundu kuyambira pomwe idakhazikitsidwa m'ma 1970s. Zinthu zatsopanozi, zotambasulidwa pamakina komanso pamanja pogwiritsa ntchito njira zolumikizirana, zimapereka kuphatikiza kwapadera kwazinthu zomwe zapangitsa kuti zikhale zofunika kwambiri pamagwiritsidwe osiyanasiyana.
Zofunikira zazikulu za BOPP
chopanda mtundu komanso chopanda fungo Chikhalidwe
Zopanda poizoni
kokhazikika Kukhazikika komanso kulimba
chidwi Kukana kochititsa
kwambiri Kulimba kwamphamvu (zodziwika bwino zimachokera ku 130-300 MPa)
kwapadera Kuwonekera (mpaka 90% kufalitsa kuwala)
Zinthu izi zayika BOPP ngati chinthu chosunthika m'mafakitale angapo, kuyambira pakupakira zakudya mpaka kupangira nsalu.
Ubwino wa BOPP Film
Zakuthupi
BOPP imaposa mphamvu komanso kulimba, yokhala ndi mphamvu yolimba yomwe imatha kufika mpaka 300 MPa polowera makina. Mawonekedwe ake owoneka bwino, okhala ndi ma translights opitilira 90%, amathandizira kuwonekera kwazinthu pamashelefu ogulitsa. Kukhazikika kwa mawonekedwe a filimuyi kumatsimikizira kuti filimuyo imagwira ntchito mosasinthasintha m'mapulogalamu osiyanasiyana, ndi kuchepa kwafupipafupi kwa 4% pa 130 ° C.
Kukana ma punctures ndi ming'alu yosinthika kumapangitsa BOPP kukhala yabwino pakuyika zoteteza. Mwachitsanzo, filimu ya 20-micron BOPP imatha kupirira mpaka 130 g/25 μm pamayesero amphamvu a dart, kuwonetsa kulimba kwake pamapulogalamu apadziko lonse lapansi.
Chemical Properties
BOPP imagwira ntchito ngati chotchinga chowopsa ku chinyezi, kuipitsidwa, ndi mankhwala owopsa. Mlingo wake wotumizira nthunzi wamadzi (WVTR) ukhoza kutsika mpaka 4-5 g/m²/tsiku pa 38°C ndi chinyezi cha 90%, kupangitsa kuti ikhale chisankho chabwino kwambiri pazinthu zomwe sizimva chinyezi.
Kukaniza kwamafuta ndi mafuta mufilimuyi, zomwe zili ndi mtengo wopitilira 7 pamlingo woyeserera wa Kit, zimakulitsa magwiridwe ake. Izi zimapangitsa BOPP kukhala chisankho chabwino kwambiri pakuyika zakudya ndikugwiritsa ntchito mafakitale, komwe chitetezo chazinthu ndizofunikira kwambiri.
Ubwino Wachilengedwe
M'dziko lamasiku ano lokonda zachilengedwe, BOPP imawala ndi zidziwitso zake zachilengedwe:
Recyclability : BOPP imagwera pansi pa code #5 (PP), kupangitsa kuti ikhale yobwezeretsanso.
Opepuka : Kachulukidwe komwe kamazungulira 0.90-0.92 g/cm³ kumathandizira kuchepetsa kutulutsa mpweya wamayendedwe.
Kupanga mphamvu zamagetsi : Njira yopangira mphamvuyi imagwiritsa ntchito mphamvu zochepa poyerekeza ndi zipangizo zina.
Kafukufuku wowunikira moyo wawo wopangidwa ndi European Polypropylene Film Manufacturers Association adapeza kuti makanema a BOPP ali ndi 40% yotsika mpweya wa carbon poyerekezera ndi mafilimu ofanana a PET.
Ubwino Wachuma
BOPP imapereka phindu lalikulu lamtengo wapatali chifukwa cha zokolola zambiri. Kuchulukana kwake kwa pafupifupi 0.90-0.92 g/cm³ kumabweretsa filimu yochulukirapo pa kulemera kwa unit poyerekeza ndi njira zina monga poliyesitala (kachulukidwe ~1.4 g/cm³). Izi zikutanthawuza kupulumutsa mtengo pakugwiritsa ntchito zinthu komanso zoyendera.
Kuvomerezedwa kwapadziko lonse kumathandizira malonda ndi kutumiza mosavuta padziko lonse lapansi. Malinga ndi malipoti amakampani, dera la Asia-Pacific ndi lomwe limayang'anira msika wa BOPP, womwe umapitilira 60% ya mphamvu zopanga padziko lonse lapansi.

Kuipa kwa BOPP Film
Kusindikiza Nkhani
Kusasindikiza koyipa kwa BOPP kumatha kukhala kovuta pamapaketi ena. Mphamvu zosindikizira zotentha zimayambira 200-400 g/25 mm, zomwe ndizotsika poyerekeza ndi makanema ena. Izi nthawi zambiri zimafunikira chithandizo chowonjezera kapena zokutira kuti zisungidwe bwino, zomwe zitha kukulitsa mtengo wopanga.
Zokhudza Mphamvu Zapamwamba
Mphamvu yotsika pansi (nthawi zambiri 29-31 mN / m) imabweretsa zovuta pakumatira kwa inki. Izi zimapangitsa kuti zikhale zovuta kusindikiza bwino, zomwe zimafunika chithandizo chapamwamba musanasindikize. Kuchiza kwa Corona kumatha kukulitsa mphamvu yapamtunda kufika pa 38-42 mN/m, koma izi zimachepa pakapita nthawi.
