Mumakore achangopfuura, polypropylene (PP) yave chinhu chinogoneka uye chakasimba, kunyanya mukugadzirwa kwemabhegi akarukwa. Inozivikanwa nekusimba kwayo uye kureruka zvivakwa, PP iri kuwedzera kufarirwa nemaindasitiri akasiyana anosanganisira ekurima, kuvaka uye kurongedza.

Iyo mbishi yemabhegi akarukwa inonyanya kugadzirwa nepolypropylene, ine simba rakanakisa uye kuchinjika. Kwete chete mabhegi aya anopokana nehunyoro nemakemikari, zvakare anodzivirira UV, achiaita akanakira kuchengetedza kunze uye kutakura zvinhu. UV inodzivirira inochengetedza zviri mukati zvakachengetedzwa kubva kukukuvara kwezuva, kuwedzera hupenyu hwezvigadzirwa mukati.

Kufambira mberi kukuru mune tekinoroji yepolypropylene yaive kuvandudzwa kwebiaxially oriented polypropylene (BOPP). Musiyano uyu unowedzera kusimba uye kujeka kwezvinhu, zvichiita kuti ive yakakodzera kudhindwa kwemhando yepamusoro uye kushambadzira. Mafirimu eBOPP anoshandiswa zvakanyanya mukurongedza maapplication kuti ape chipingamupinyi pakunyorova uye oksijeni, iyo yakakosha kuchengetedza chikafu.

Mukuwedzera, sezvo matambudziko ezvakatipoteredza anowedzera,kudzokororwa kwe polypropyleneyakagamuchira ngwariro inowedzera. PP nderimwe remapurasitiki anogona kushandiswa zvakare, uye zvirongwa zviri kuitika zvino kukurudzira kuunganidzwa uye kushandiswa zvakare. Nekudzokorodza polypropylene, vagadziri vanogona kuderedza marara uye kudzikisa kabhoni tsoka, nekudaro zvichibatsira kune remangwana rakagadzikana.

Sezvo indasitiri inoenderera mberi nekuvandudza, kudiwa kwezvinhu zvemhando yepamusoro, zvakatipoteredza zvakadai sepolypropylene zvinotarisirwa kukura. Nezvayo zvakasarudzika zvivakwa uye kugona kudzokorodza, polypropylene inotarisirwa kuita basa rakakosha mukuvandudza mhinduro dzekutakura dzekutakura, kunyanya mumunda wemabhegi akarukwa. Kuchinja uku hakungobatsiri vanogadzira chete, asiwo kunopindirana nekuedza kwepasi rose kusimudzira mutoro wezvakatipoteredza.
