M'munda wa zipangizo zamakono mafakitale, mtanda filimu wakhala kusankha zofunika kwa mafakitale ambiri chifukwa cha zinthu zabwino thupi ndi zochitika lonse ntchito. Kaya ndikumanga zotchinga madzi, zonyamula katundu kapena chitetezo chamagetsi, filimu yodutsa imayamikiridwa chifukwa champhamvu zake, kukana nyengo komanso kukhazikika. Nkhaniyi isanthula mozama njira yoyendetsera filimuyi kuti ithandize owerenga kumvetsetsa bwino momwe kamangidwe ka zinthu zofunikazi zimapangidwira.
Kupanga filimu ya mtanda kumayamba ndi kusankha ndi kugawaniza zipangizo. Nthawi zambiri, ma polima apamwamba a molekyulu amagwiritsidwa ntchito ngati zida zoyambira, monga polyethylene (PE), polypropylene (PP) kapena polyester (PET), ndipo zowonjezera monga UV inhibitors, antioxidants kapena plasticizers amawonjezedwa malinga ndi zofunikira za kagwiritsidwe ntchito ka filimuyo. Pambuyo metering yeniyeni, zopangira kulowa kusakaniza chipangizo kuonetsetsa yunifolomu kugawa zosakaniza, kuyala maziko a processing wotsatira.
Chotsatira ndi kuumba kwa extrusion. Zosakanizazo zimatenthedwa kuti zisungunuke ndi chotungira ndi kuzitulutsa m'mapepala owonda kudzera mu T-die. Pochita izi, kuwongolera kutentha ndi kupanikizika ndikofunikira, zomwe zimakhudza mwachindunji makulidwe ndi kukhazikika kwa filimuyo. Filimu yosungunuka yotulutsidwayo imalowa m'gulu lozizira lozizira, imapanga mawonekedwe, ndikupanga filimu yoyamba.
Pambuyo kuzirala, filimuyo imalowa mu siteji yotambasula, yomwe ndi sitepe yaikulu ya filimu ya mtanda. Kanemayo amayamba kutambasula motalika, ndiye kuti, kumangika kumagwiritsidwa ntchito kumalo amodzi kuti agwirizane ndi unyolo wa maselo pamodzi ndi njira yotambasula, potero kuwongolera mphamvu ndi kukhazikika kwa filimuyo. Pambuyo pake, filimuyo imatambasulidwa mopingasa, nthawi zambiri kutentha kwambiri, kuti ikonzenso unyolo wa maselo kumbali ina, ndikupanga mawonekedwe otambasulidwa a biaxially. Izi biaxial kutambasula ndondomeko amapereka mtanda filimu zabwino makina katundu ndi kutentha kukana.
Kanema wotambasulidwa amafunikanso kuthandizidwa ndi chithandizo chapamwamba, monga chithandizo cha corona kapena zokutira, kuti apititse patsogolo kusindikiza kapena kumamatira kuzinthu zina. Pomaliza, filimuyo imadulidwa, kugubuduzika ndikuyesedwa bwino kuti zitsimikizire kuti mpukutu uliwonse wazinthu ukukumana ndi zomwe zanenedwa.
Njira yopangira filimu yamtanda imaphatikiza sayansi ya zinthu za polima, uinjiniya wamakina ndi ukadaulo wowongolera bwino, komanso zovuta zake komanso zolondola zimatsimikizira momwe chomaliza chimagwirira ntchito. Ndi kupita patsogolo kosalekeza kwaukadaulo, gawo logwiritsira ntchito mafilimu ophatikizika lidzakulitsidwanso kuti lipereke mayankho ogwira mtima m'mafakitale osiyanasiyana.
