Polypropilene cyangwa PP nigiciro gito cya thermoplastique yumucyo mwinshi, urumuri rwinshi nimbaraga nziza.Ifite ingingo yo hejuru yo gushonga kuruta PE, ituma ikwiranye na porogaramu zisaba sterisizione ku bushyuhe bwinshi.Ifite kandi igihu gike hamwe nuburabyo bwinshi.Mubisanzwe, ubushyuhe bwo gufunga ubushyuhe bwa PP ntabwo ari bwiza nkubwa LDPE.LDPE ifite kandi imbaraga zo kurira hamwe no kurwanya ubushyuhe buke.
PP irashobora guhurizwa hamwe bigatuma habaho kunoza imyuka ya gazi yo gusaba ibisabwa aho igihe kirekire cyibicuruzwa ari ngombwa.Filime ya PP ikwiranye ninganda nini yinganda, abaguzi, hamwe n’imodoka.
PP irashobora gukoreshwa neza kandi irashobora gusubirwamo byoroshye mubindi bicuruzwa byinshi kubikorwa bitandukanye.Ariko, bitandukanye nimpapuro nibindi bicuruzwa bya selile, PP ntishobora kubora.Kuruhande, imyanda ya PP ntabwo itanga uburozi cyangwa ibicuruzwa byangiza.
Ubwoko bubiri bwingenzi ni polypropilene (CPP) hamwe na polypropilene (BOPP).Ubwoko bwombi bufite urumuri rwinshi, optique idasanzwe, imikorere myiza cyangwa nziza yo gufunga ubushyuhe, kurwanya ubushyuhe bwiza kuruta PE, hamwe nuburyo bwiza bwo gukumira.
Kora Filime ya Polypropilene (CPP)
Kora polypropilene idahuye (CPP) mubisanzwe usanga porogaramu nkeya ugereranije na polypropilene (BOPP).Nyamara, CPP yagiye yunguka buhoro buhoro nk'ihitamo ryiza mubikoresho byinshi gakondo byapakirwa kimwe nibidapakira.Imiterere ya firime irashobora guhindurwa kugirango ihuze ibintu byihariye bipfunyika, imikorere, nibisabwa.Muri rusange, CPP ifite amarira menshi no kurwanya ingaruka, imikorere yubushyuhe bukonje hamwe nubushuhe bwo gufunga ubushyuhe kuruta BOPP.
Filime ya Polypropilene yerekanwe Biaxically (BOPP)
Biaxally yerekanwe polypropilene cyangwa BOPP1 niyo firime ikomeye ya polypropilene.Nuburyo bwiza cyane kuri selofane, impapuro zishashara, na aluminiyumu.Icyerekezo cyongera imbaraga zingutu no gukomera, bigabanya kurambura (bigoye kurambura), kandi bigateza imbere optique, kandi bigateza imbere imyuka ya barrière.Muri rusange, BOPP ifite imbaraga zingana, modulus yo hejuru (stiffness), kurambura hasi, inzitizi ya gaze nziza, hamwe numwotsi wo hasi kuruta CPP.
Porogaramu
Filime ya PP ikoreshwa mubintu byinshi bisanzwe bipakira nka gasegereti, bombo, ibiryo ndetse no gupfunyika ibiryo.Irashobora kandi gukoreshwa mukugabanya gupfunyika, gufata kaseti, impapuro hamwe na sterile bipfunyika bikoreshwa mubuvuzi.Kuberako PP ifite impuzandengo ya gaze ya gazi gusa, akenshi iba isizwe hamwe nizindi polymers nka PVDC cyangwa acrylic itezimbere cyane imiterere ya bariyeri.
Bitewe numunuko muke, imiti myinshi irwanya imiti nubusembure, amanota menshi ya PP arakwiriye gupakira porogaramu nkuko amategeko ya FDA abiteganya.
