isicelo

Kubaluleke kakhulu ukupakishwa kwezinto eziguquguqukayo ezinoluhlu olubanzi lwezicelo.Ifilimu ye-BOPP ayinambala, ayinavumba, ayinavumba, ayinayo ityhefu, kwaye inamandla aphezulu, amandla empembelelo, ukuqina, ukuqina kunye nokungafihli kakuhle.Amandla angaphezulu kwefilimu ye-BOPP aphantsi, kwaye unyango lwe-corona luyafuneka ngaphambi kwegluing okanye ukuprinta.Nangona kunjalo, emva konyango lwe-corona, ifilimu ye-BOPP inokuguquguquka okuhle kokuprinta kwaye inokuprintwa ngaphezulu ukuze ifumane inkangeleko egqibeleleyo, ke ihlala isetyenziswa njengesixhobo somgangatho wefilimu edibeneyo.Ifilimu ye-BOPP nayo ineziphene, ezifana nokuqokelelwa lula kombane ongatshintshiyo kwaye akukho kutywinwa kobushushu.Kumgca wokuvelisa ngesantya esiphezulu, ifilimu ye-BOPP ixhomekeke kumbane ongatshintshiyo, ngoko ke kuyimfuneko ukuba kufakwe i-static remover.Ukuze ufumane ifilimu ye-BOPP etywinwe ubushushu, iglue ye-resin etywiniweyo yobushushu, efana ne-PVDC latex, i-EVA latex, njl. indlela ye-co-extrusion kunye nokudibanisa ivelisa ifilimu ye-BOPP evaliweyo ngobushushu.Lo mboniso bhanyabhanya usetyenziswa kakhulu ekupakishweni kwesonka, iimpahla, izihlangu neekawusi, kunye noqweqwe olugqunyiweyo lwecuba kunye neencwadi.Amandla okukrazula kwefilimu yeBOPP aphuculwe emva kokwelula, kodwa amandla esibini okukrala aphantsi kakhulu.Ngoko ke, akukho kunciphisa kufuneka kushiywe kuzo zombini iziphelo zefilimu ye-BOPP, ngaphandle koko ifilimu ye-BOPP iya kukrazulwa ngokulula ngexesha lokushicilela kunye ne-lamination.Emva kokuba i-BOPP ifakwe kwi-self-adhesive, i-tape yokutywina inokuveliswa, eyimarike enenani elikhulu le-BOPP.

Ifilimu yeBOPP inokuveliswa ngendlela yefilimu yetyhubhu okanye indlela yefilimu ecaba.Iipropati zeefilimu ze-BOPP ezifunyenwe ngeendlela ezahlukeneyo zokucwangcisa ziyahluka.Ifilimu ye-BOPP eveliswe yi-flat film method inomlinganiselo omkhulu wokwelula (ukuya kwi-8-10), ngoko ke amandla aphezulu kunendlela yefilimu ye-tube, kwaye ukufana kobunzima befilimu bungcono.

Ukuze ufumane intsebenzo engcono iyonke, idla ngokuveliswa yindlela edibeneyo yoluhlu oluninzi ngexesha lokusetyenziswa.I-BOPP inokudityaniswa nezinto ezininzi ezahlukeneyo ukuhlangabezana neemfuno zezicelo ezizodwa.Ngokomzekelo, i-BOPP inokudibaniswa ne-LDPE (CPP), i-PE, i-PT, i-PO, i-PVA, njl.Iifilimu ezidibeneyo ezidibeneyo zingasetyenziswa ekutyeni okunamafutha.
