The zinchito katundu ma CD zipangizo filimu mwachindunji amayendetsa ntchito chitukuko cha gulu flexible ma CD zipangizo. Zotsatirazi ndizofotokozera mwachidule za magwiridwe antchito azinthu zingapo zomangira zomwe zimagwiritsidwa ntchito.
1. Zomwe zimagwiritsidwa ntchito ponyamula katundu: filimu ya PE
Zipangizo za PE zotsekedwa ndi kutentha zasintha kuchokera ku mafilimu omwe amawombedwa ndi gulu limodzi kupita ku mafilimu amitundu yambiri, kotero kuti mapangidwe amkati, apakati ndi akunja apangidwe mosiyana. Mapangidwe ophatikizika amitundu yosiyanasiyana ya utomoni wa polyethylene amatha kutulutsa kutentha kosiyana kosindikiza, kutentha kosiyanasiyana kosindikiza kutentha, kuipitsidwa kosiyana koletsa kusindikiza,hot zomatira mphamvu, odana ndi malo amodzi zotsatira, etc., kukwaniritsa zofunika katundu ma CD ndi zipangizo PE filimu ndi katundu ntchito zosiyanasiyana.
M'zaka zaposachedwa, mafilimu a biaxially oriented polyethylene (BOPE) apangidwanso, omwe amapangitsa kuti mafilimu a polyethylene akhale olimba komanso amakhala ndi mphamvu zotsekera kutentha.
2. Mafilimu a CPP
Zida za CPP zimagwiritsidwa ntchito kwambiri mu BOPP / CPP mawonekedwe opangira kuwala kwa chinyezi, koma mitundu yosiyanasiyana ya utomoni wa CPP imatha kupangidwanso ndi mawonekedwe osiyanasiyana a filimuyo, monga kukana kutentha kwapang'onopang'ono, kukana kutentha kwambiri, kutsika. kutentha kosindikiza, kulimba kwamphamvu kwambiri, kukana dzimbiri, ndi zina zomwe zimagwira ntchito pazinthu zotsekera kutentha.
RZaka zaposachedwapa, makampaniwa apanganso filimu ya CPP matte, kuonjezera maonekedwe a matumba a mafilimu a CPP osanjikiza.
3. Zipangizo zamakanema a BOPP
Kanema wophatikizira wopepuka yemwe amagwiritsidwa ntchito kwambiri ndi filimu wamba ya BOPP yowala ndi filimu ya matte ya BOPP, palinso filimu yosindikiza kutentha ya BOPP (kusindikiza kutentha kwa mbali imodzi kapena mbali ziwiri), filimu ya ngale ya BOPP.
BOPP imadziwika ndi mphamvu zolimba kwambiri (zoyenera kusindikiza kwamitundu yambiri), zida zabwino kwambiri zotchingira nthunzi zamadzi, zomwe zimagwiritsidwa ntchito kwambiri pamapaketi opepuka osagwira chinyezi pankhope yazinthu zosindikizidwa.
filimu ya matte ya BOPP yokhala ndi zokongoletsera za matte zofanana ndi pepala. Kanema wosindikiza kutentha wa BOPP atha kugwiritsidwa ntchito ngati choyikapo chosanjikiza chimodzi, monga kukulunga mkati mwa maswiti ndi. Kanema wa ngale ya BOPP imagwiritsidwa ntchito kwambiri pakuyika zinthu za ayezi-kirimu zosindikizira kutentha, imatha kupulumutsa inki yoyera, kachulukidwe kakang'ono, 2 mpaka 3N / 15mm kusindikiza mphamvu kuti thumba likhale losavuta kutsegula kuti mutulutse zomwe zili.
Kuphatikiza apo, monga filimu yolimbana ndi chifunga ya BOPP, filimu ya laser ya holographic OPP, pepala lopangidwa ndi PP, filimu ya BOPP yowonongeka ndi mafilimu ena a BOPP omwe amagwira ntchito nawonso adatchuka ndikugwiritsidwa ntchito mosiyanasiyana.
4. Zomwe zimagwiritsidwa ntchito poyika zida: PET filimu zakuthupi
Kanema wamba wamba wa 12MICRONS PET amagwiritsidwa ntchito kwambiri pamapaketi osinthika, mphamvu zamakina zamapaketi ake okhala ndi laminated ndizokwera kwambiri kuposa zopangidwa ndi zigawo ziwiri za BOPP (zotsika pang'ono kuposa zopangidwa ndi BOPA zamitundu iwiri), komanso mphamvu yotchinga mpweya. filimu yophatikizika ya BOPP/PE (CPP) kuti muchepetse nthawi 20 mpaka 30.
Kukaniza kutentha kwa zida za PET ndikwabwino kwambiri, ndipo kumatha kupangidwa kuti matumba abwino azikhala osalala. filimu ya PET yowotcha kutentha, filimu ya matte PET PET yowotcha kutentha, filimu ya matte PET, filimu ya polyester yotchinga kwambiri, filimu ya PET twist, filimu yong'ambika ya PET ndi zinthu zina zogwira ntchito zimagwiritsidwanso ntchito.
5. Wamba ma CD zakuthupi : nayiloni filimu
Kanema wa nayiloni wopangidwa ndi Biaxially amagwiritsidwa ntchito kwambiri mu vacuum, matumba otentha komanso otenthetsera chifukwa champhamvu zake, kukana kuphulika kwakukulu, kukana kutentha kwambiri komanso chotchinga chabwino cha okosijeni.
Zikwama zazikulu zokhala ndi laminated zoposa 1.7kg zimagwiritsanso ntchito mawonekedwe a BOPA//PE pofuna kukana kugwa bwino.
Kanema wa nayiloni, womwe umagwiritsidwa ntchito kwambiri ku Japan pakuyika chakudya chozizira, chomwe chimakhala ndi kukana kutentha kwapang'onopang'ono, kuchepetsa kusweka kwa thumba panthawi yosungirako kutentha komanso mayendedwe.
6. Zinthu Zophatikiza Zophatikiza : Chophimba cha Aluminium Filimu ya Metalized
Vacuum aluminizing ndi filimu (monga PET, BOPP, CPP, Pe, PVC, etc.) pamwamba mapangidwe wosanjikiza wandiweyani zotayidwa wosanjikiza, motero kwambiri kuonjezera filimu pa nthunzi madzi, mpweya, kuwala chotchinga mphamvu. , ambiri ankagwiritsa ntchito mu gulu flexible ma CD VMPET, VMCPP zipangizo.
VMPET kwa atatu wosanjikiza laminating, VMCPP kwa awiri wosanjikiza laminating.
OPP//VMPET//PE dongosolo tsopano lagwiritsidwa ntchito mokhwima mu atolankhani masamba, zikumera mankhwala mu vacuum otentha ma CD. Pe dongosolo tsopano okhwima ntchito Finyani masamba, zikumera mankhwala mu vakuyumu otentha ma CD, kuti athetse zofooka za mankhwala wamba aluminiyamu, zotayidwa wosanjikiza zosavuta kusamuka, musakane zolakwa za otentha, chitukuko cha VMPET mankhwala ndi pansi ❖ kuyanika mtundu, isanayambe kapena itatha kuwira kwa peeling mphamvu zoposa 1.5N/15mm, ndi wosanjikiza zotayidwa sizikuwoneka. kusamuka, kupititsa patsogolo ntchito yonse yotchinga ya thumba.
7. Common ma CD zipangizo: Aluminium zojambulazo
Aluminiyamu zojambulazo zomangika zosinthika nthawi zambiri zimakhala 6.5μm kapena 9μM 12microns makulidwe, zotayidwa zojambulazo ndi theoretically chotchinga zinthu mkulu, permeability madzi, permeability mpweya, kuwala permeability ndi "0", koma kwenikweni pali pinholes mu zojambulazo aluminiyamu ndi lopinda osauka pinhole kukana, pali angapo chotchinga ma CD enieni. zotsatira sizabwino. Chinsinsi cha kugwiritsa ntchito zojambulazo za aluminiyamu ndikupewa ma pinholes panthawi yokonza, kulongedza ndi kuyendetsa, motero kuchepetsa mphamvu yeniyeni yotchinga. M'zaka zaposachedwa, pali chizolowezi choti zida za aluminiyamu zojambulidwa kuti zisinthidwe ndi zida zomangira zotsika mtengo m'malo awo ogwiritsira ntchito.
8. Zomwe zimagwiritsidwa ntchito nthawi zambiri zomangira: mafilimu otchinga kwambiri
Makamaka filimu yokutira ya PVDC (filimu yokutira ya K), filimu yokutira ya PVA (Filimu yokutira).
PVDC ili ndi chotchinga chabwino kwambiri cha okosijeni ndi kukana chinyezi, ndipo imakhala yowonekera bwino kwambiri, filimu yophimbidwa ya PVDC yomwe imagwiritsidwa ntchito m'munsi filimuyi imakhala BOPP, BOPET, BOPA, CPP, etc., komanso ikhoza kukhala Pe, PVC, cellophane ndi mafilimu ena. ma CD osinthika omwe amagwiritsidwa ntchito kwambiri mu filimu ya KOPP, KPET, KPA.
9. Zida Zophatikiza Zophatikiza: Co-extruded High Barrier Films
Co-extrusion ndi mapulasitiki awiri kapena osiyana, kupyolera muzitsulo ziwiri kapena zoposa ziwiri, motero, kuti mapulasitiki osiyanasiyana asungunuke ndi pulasitiki kwa mutu wa mutu, kukonzekera mafilimu ophatikizika a njira yowumba. Mafilimu ophatikizika a co-extruded barriers nthawi zambiri amapangidwa kuchokera ku kuphatikiza mapulasitiki otchinga, mapulasitiki a polyolefin ndi zomatira zamitundu itatu yayikulu yazinthu, zotchinga zotchinga zimakhala makamaka PA, EVOH, PVDC, ndi zina zambiri.
Pamwambapa ndi wamba ma CD zipangizo, kwenikweni, osachepera ntchito okusayidi nthunzi ❖ kuyanika, PVC, PS, PEN, pepala, etc., ndi utomoni womwewo malinga ndi njira zosiyanasiyana processing, formulations osiyana akhoza kupangidwa ndi kusinthidwa osiyana. zinchito za filimu zakuthupi. Lamination mafilimu osiyanasiyana zinchito, kudzera youma lamination, zosungunulira-free lamination, extrusion lamination ndi luso lina gulu kutulutsa zinchito gulu flexible ma CD zipangizo kukwaniritsa zosowa zosiyanasiyana.mankhwalakuyika.
