BOPA Yotsatizana Ndi Mbali Imodzi Corona Yothandizidwa
OA1 ndiye mbali imodzi ya corona yomwe imayendetsedwa motsatizana ndi BOPA yokhala ndi zinthu zabwino kwambiri zomwe ndizoyenera kulongedza mapulogalamu.

OA1 itha kugwiritsidwa ntchito posindikiza ma CD mkati mwamitundu 6 (kuphatikiza mitundu 6) ndi mapaketi wamba okhala ndi m'mphepete mwake m'lifupi ≤ 3cm komanso osafunikira chimango.Itha kusunga pang'ono kupotoza ndi kupindika pambuyo pa kuwira ndi koyenera kunyamula zolemera ndi mafupa, misana yomwe imafuna kukana kwambiri kuti iwonongeke komanso kukhudzidwa, monga mapepala ogwiritsidwa ntchito pamasamba okazinga (mpiru wonyezimira, mphukira za nsungwi, masamba okazinga, ndi zina zotero. ), nsomba zam'madzi, mtedza, ufa wochapira, Zakudyazi za udong, magazi a bakha, zipatso zofewa zam'chitini, makeke, keke ya mwezi, pudding yachikhalidwe yaku China, ma dumplings, zosakaniza za mphika wotentha, chakudya chachisanu, ndi zina zambiri.
Njira Zoyikira Pakuyika Zosinthika
Njira zophatikizira zophatikizira zosinthira zosinthika makamaka zimaphatikizira zowuma zowuma, zonyowa zophatikizika, zophatikizika za extrusion, co-extrusion composite ndi zina zotero.
● Chophatikizika chowuma
M'maukadaulo osiyanasiyana opangira filimu yophatikizika, kompositi yowuma ndiukadaulo wachikhalidwe komanso wogwiritsidwa ntchito kwambiri ku China, womwe umagwiritsidwa ntchito kwambiri ponyamula zakudya, mankhwala, zodzola, zofunikira zatsiku ndi tsiku, zinthu zopepuka zamakampani, mankhwala, zinthu zamagetsi, ndi zina zambiri. .
● Kaphatikizidwe konyowa
Chonyowa chophatikizika ndi kuvala wosanjikiza zomatira pamwamba pa gulu gawo lapansi (pulasitiki filimu, aluminiyamu zojambulazo).Pamene zomatira si youma, izo laminates ndi zipangizo zina (pepala, cellophane) kudzera kuthamanga wodzigudubuza, ndiyeno zouma mu gulu filimu kudzera otentha kuyanika ngalande.
● Kutulutsa kophatikiza
Extrusion pawiri ndi kusungunula polyethylene ndi zinthu zina thermoplastic mu extruder pambuyo extrusion mu lathyathyathya kufa pakamwa, kukhala pepala filimu outflow yomweyo ndi wina kapena mitundu iwiri ya mafilimu mwa kuzirala mpukutu ndi gulu atolankhani mpukutu laminate pamodzi.
● Chotsani filimu yokutira
Extrusion yokutira ndi njira yopangira filimu yophatikizika posungunuka thermoplastic, monga polyethylene kuchokera pamutu wathyathyathya ndikukankhira pagawo lina pakati pa odzigudubuza awiri polumikizana kwambiri.
● Filimu yamagulu ambiri
Extrusion pawiri ndi extruded utomoni sandwiched pakati magawo awiri, izo azisewera magawo awiri pamodzi zomatira kanthu, komanso gulu wosanjikiza.
