Munyika iri kusimukira yekurongedza, kunyanya mupp yakarukwa bag industry.companies ari kuwedzera kutendeukira kune zvinoumbwa zvinhu zvekuwedzera kuchengetedza chigadzirwa uye kuenderera. Idzo dzinonyanya kufarirwa sarudzo dzepp dzakarukwa mabhegi evharuvhu mhando nhatu dzakasiyana dzekurongedza: PP+PE, PP+PE+OPP uye PP+PE ine imwechete layer kraft bepa. Mhando imwe neimwe inoshandisa chinangwa chakasiyana uye inosangana nezvinodiwa zvakasiyana-siyana zvemaindasitiri.

1. PP + PE (polypropylene uye polyethylene): Musanganiswa uyu unoshandiswa zvakanyanya pakuita kwayo kwakanakisa-uchapupu hwekuita uye kusimba. Iyo PP layer inopa simba uye kubvarura kuramba, nepo PE layer inopa kuchinjika uye inovharika pamusoro. Iyi mhando yekurongedza yeblock bottom valve bagyakanakira zvigadzirwa zvekudya, kuve nechokwadi kutsva uye kuwedzera hupenyu hwesherufu. Iyo inowanzo shandiswa mukurongedza kwezvinhu zvevatengi, uko kuchengetedzwa kubva kune zvakatipoteredza kwakakosha.

2. PP+PE+OPP (Oriented Polypropylene): Iyi composite yepamusoro inotora mabhenefiti emhando yekutanga nhanho mberi nekuwedzera OPP layer yeblock bottom valve mabhegi, iyo inovandudza kujeka uye kudhinda. Iyo OPP layer ine inopenya pamusoro uye inoyevedza sarudzo yemabhureki anotarisa kuwedzera kukwezva kwezvigadzirwa zvavo. Rudzi urwu runonyanya kufarirwa mune zvekudya zvekudya uye maindasitiri ezvekudya, uko kutaridzika kunoita basa rakakosha mukusarudza kwevatengi.

3. PP+PE Single Ply Kraft Pepa: Iyi eco-friendly sarudzo yead* nyeredzi bhegiinosanganisa kusimba kwepolypropylene uye polyethylene nekukwezva kwechisikigo kwekraft bepa. Iyo kraft paper layer haingo wedzera rustic aesthetic, asi zvakare inovandudza kudzokorora. Rudzi urwu rwekurongedza rwuri kuwedzera kufarirwa mune organic uye zvakasikwa zvigadzirwa chikamu, uko kusimudzira ndiko kunetseka kukuru kune vatengi.

Sezvo makambani anoramba achiisa pamberi pekusimudzira uye kutendeseka kwechigadzirwa, aya akaumbwa ekurongedza mhinduro achaita basa rakakosha mune ramangwana reindasitiri.
