Kugwiritsa ntchito sera ya polyethylene mu zokutira ufa kumaphatikizapo sera ya polyethylene, sera ya polypropylene, sera ya polytetrafluoroethylene, sera ya polyamide, ndi zina zotero.Pankhani yogwirizana komanso yotsika mtengo,pa waxndi yabwino ndipo imatha kukwaniritsa zofunikira zonse pakuumitsa ndi kukana kukankha, motero kukhala ndi mapulogalamu osiyanasiyana.

Mafuta ena a sera samangokhalira kuuma komanso kukana kukanda, komanso amakhala ndi kutha kwapadera.Mwachitsanzo, sera ya polypropylene ingagwiritsidwe ntchito ngati m'malo mwa zowonongeka zowonongeka mu zokutira za ufa zomwe sizifuna zotsatira za kutha kwakukulu.Koma panthawiyi, mlingowo ndi wokulirapo kuposa 2%, ndipo nthawi zina pamakhala kutsika kwa phula mu ❖ kuyanika.
Poikapo, ufa wa sera nthawi zambiri umakhala wophatikizika, ndipo palinso njira ziwiri zogwiritsira ntchito: kuwonjezera ndi kusakaniza positi.Wax wosakanizika wamtsogolo ndi micro ufa wa tinthu tating'onoting'ono kwambiri, komanso tinthu tambiri tating'onoting'ono tiyenera kusakanikirana ndikuchotsa limodzi ndi zinthu zosaphika kuti zizigwiritsa ntchito.
1. Kuwonjezera zosakwana 1% flakephula la polyethyleneku chilinganizo akhoza kuonjezera kupanga ndi kuchepetsa mawotchi kuvala pa extrusion, makamaka mikhalidwe ndi magawano zambiri, kumabweretsa zotsatira zazikulu.
2. Kuthira 0.5-0.8% polyethylene ndi amide wosakanizidwa sera ku chilinganizo akhoza kusintha youma ufa fluidity ndi kukwaniritsa ngakhale kugawa.

3. Kusalala, kukana kukanda, kutulutsa mpweya, kutsekereza madzi, kusanja, ndi kuchepetsa gloss ya filimu yokutira pambuyo powonjezera.
4. Ufa wa sera wamba ukhoza kupititsa patsogolo kukweza kwa filimu kapena kuonjezera chidzalo, koma pali kutha pang'ono malingana ndi zosiyanasiyana ndi mlingo.
Kuyanjana pakati pa mitundu yosiyanasiyana ya sera kungathe kusintha kwambiri makina a filimu yokutira, koma palinso malingaliro olakwika pakugwiritsa ntchito.Mwachitsanzo, kuwonjezera phula pang'ono mu njira yosindikizira ndiyopindulitsa pakung'ambika kwa mapepala, ndipo kuwonjezera sera yambiri kungayambitse kusamutsidwa kosadziwika bwino kwa zokutira.

Tizidutswa ta sera tambirimbiri titha kuwonjezedwa, zomwe zimapangitsa kuti mabowo azing'ambika kapena kuwonongeka kwa tinthu pa ❖ kuyanika pamwamba;Ma amide wax ena amawonjezeredwa kwambiri, zomwe zimatha kuyambitsa chifunga pamwamba pa zokutira ndikupangitsa kuti gloss iwonongeke kwambiri.Choncho, pogwiritsira ntchito, choyamba, m'pofunika kumvetsetsa zakuthupi zamagulu osiyanasiyana a ufa wa sera, ndipo kachiwiri, pamene sera ya ufa imagawidwa, mlingo uyenera kuyendetsedwa moyenerera mpaka 2%.
