Polypropylene cast film (CPP) inoshandiswa zvakanyanya.CPP isiri-kutambanudza, isina-yakatarisana yakakandwa firimu inogadzirwa nekunyunguduka kukanda quenching.Kuenzaniswa nefirimu rakapeperetswa, rinoratidzwa nekukurumidza kugadzira kukurumidza, kuburitsa kwakanyanya, uye yakanaka firimu pachena, gloss uye ukobvu kufanana.Panguva imwecheteyo, nekuti iri firimu rekunze rakatsetseka, maitiro anotevera akadai sekudhinda uye lamination ari nyore kwazvo, saka anoshandiswa zvakanyanya mukurongedza machira, maruva, chikafu, uye zvinodiwa zvezuva nezuva.
Pane nzira mbiri dzekugadzira CPP: single-layer casting uye multi-layer co-extrusion casting.Iyo imwe-layer firimu inonyanya kuda kuti zvinhu zvive zvakanaka zvakaderera tembiricha yekupisa chisimbiso kuita uye kuchinjika.Multi-layer co-extrusion cast film inogona kupatsanurwa kuita zvidimbu zvitatu: kupisa seal seal layer, support layer uye corona layer.Sarudzo yezvinyorwa yakafara kupfuura iyo imwe-layer firimu.Zvishandiso zvinosangana nezvinodiwa zvega rega rega zvinogona kusarudzwa mumwe nemumwe kuti ape iyo firimu maitiro akasiyana, basa uye chinangwa.Pakati pazvo, kupisa-kuvharwa kwechisimbiso kunoda kuvharwa-kupisa, izvo zvinoda kuti zvinhu zvive nechepasi kunyunguduka, yakanaka inopisa-kunyunguduka, kupisa-kupisa kwekushisa, uye kuiswa chisimbiso nyore: chisimbiso chinotsigira firimu uye chinowedzera kuoma kwefirimu.Iyo corona layer inoda kudhindwa kana kugadzirwa simbi, iyo inoda kunetsa kwepakati pepamusoro, uye kuwedzera kwezvinowedzera kunofanirwa kuganhurwa.
CPP yakakandwa firimu ine yakanakisa kupisa chisimbiso kuita uye kujeka kwakanakisa, uye ndeimwe yemahombe ekurongedza anoumba ma substrates.Inoshandiswa kugadzira mafirimu ekubika ekupisa, vacuum aluminized films, nezvimwewo. Musika une tarisiro huru.
