Indasitiri yechikafu inonyanya kushandisa BOPP plastiki kurongedza.Mabhegi eBOPP ari nyore kudhinda, jasi uye laminate izvo zvinoita kuti ive yakakodzera kurongedza zvigadzirwa senge zvinyowani zvigadzirwa, confectionaries uye snacks.Pamwe chete neBOPP, OPP, uye PP mabhegi anoshandiswawo kurongedza.Polypropylene yakajairika polymer pakati peatatu anoshandiswa kugadzira mabhegi.
OPP inomirira Oriented Polypropylene, BOPP inomirira Biaxially Oriented Polypropylene uye PP inomirira Polypropylene.Vese vari vatatu vanosiyana pamaitiro avo ekugadzira.Polypropylene inozivikanwawo sepolypropene ndeye thermoplastic semi-crystalline polymer.Iyo yakaoma, yakasimba uye ine high impact resistance.Mapochi ekumira, maspout pouches uye ziplock pouche anogadzirwa kubva ku polypropylene.
Zvakaoma kwazvo kusiyanisa pakati peOPP, BOPP uye PP mapurasitiki pakutanga.Musiyano unogona kunzwika nekubata sezvo PP yakapfava nepo OPP ine brittle.Izvo zvakakosha kuti unzwisise kushandiswa kweOPP, PP uye BOPP mabhegi mune chaiyo-yenyika zvinhu zvekuzvisiyanisa.ThePPkana mabhegi epolypropene anoshandiswa semasaga asina kurukwa.Dzinorapwa kuitira kuti dzive mwando kana kuti dzitore mvura.
Diapers, sanitary napkins uye mafirita emhepo pakati pezvimwe zvinhu zvakajairika PP zvigadzirwa.Zvinhu zvakafanana zvinoshandiswawo kugadzira zvipfeko zvinopisa sezvo zvichipa tembiricha inodzivirira.OPP mabhegi akajeka muruvara uye ane yakakwira tensile simba.Inoshingirira kune tembiricha yepamusoro asi inounyana kana ikaunzwa mukushandiswa kwakashata.Transparent adhesive matepi anogadzirwa achishandisa mafomula akafanana.
Izvo zvakaoma kubvarura uye mabhegi eOPP anoshandiswa mukurongedza matehwe nembatya pakati pezvimwe.BOPP mabhegi mabhegi akajeka epolyethylene.Iyo biaxial orientation inovapa kujeka kutaridzika uye inovaita kuti vakwanise kushambadzira nekudhinda pamusoro.BOPP mabhegi anoshandiswa kutengesa kurongedza.Iyo biaxial orientation inowedzera simba uye vanogona kutakura mitoro inorema.
Aya masaga haapindi mvura.
Zvigadzirwa zviri mukati mavo zvinodzivirirwa kubva kune unyoro kwenguva yakareba.Ndivo sarudzo yekutanga muindasitiri yekurongedza machira.PP, OPP uye mabhegi eBOPP anoshingirira kune acid, alkali uye organic solvents.Ichi ndicho chikonzero nei vachishandiswa muindasitiri yekurongedza uko kuchengetedza uye zvekufambisa pasi pekuchinja kwemhepo hazvigone kudzivirirwa.Ivo vanogadzira chigadzirwa kubva mukunyoro uye guruva senge mafirimu ekudya.
Ivo vanogona kudzokororwa uye kugadzira kwavo kunosanganisira kushoma kabhoni kubuda.PP, BOPP uye OPP mabhegi zvakare akanaka kubva kune zvakatipoteredza maonero.Rishi FIBC inogadzira bhegi reBOPP uye inoripa nemitengo inodhura yemusika.
