Monga zinthu zosawononga chilengedwe, zipangizo za PP zakhala zikugwiritsidwa ntchito kwambiri popaka, ndipo zipangizo zobwezeretsanso za PCR zawonjezeredwanso ku chitukuko cha makampani. Monga wolimbikitsa ma paketi osawononga chilengedwe,Topfeelpack yakhala ikupanga zinthu zambiri zopangidwa ndi PP kuti ikwaniritse zosowa zamsika.
Zipangizo za PP (polypropylene) zimagwiritsidwa ntchito kwambiri mumakampani opanga ma CD chifukwa cha magwiridwe antchito ake abwino komanso kusinthasintha kwake. Ndi polima ya thermoplastic yodziwika bwino chifukwa cha mphamvu zake zambiri, kulimba, komanso kukana mankhwala ndi chinyezi. Zipangizozi zimagwiritsidwa ntchito m'mitundu yonse ya ma CD, kuphatikizapo ziwiya, mabotolo, matumba ndi mafilimu.
Chimodzi mwa ubwino waukulu wogwiritsa ntchito zinthu za PP polongedza ndi kupepuka kwake. PP ndi yopepuka kwambiri kuposa zinthu zina monga galasi kapena chitsulo, zomwe zimapangitsa kuti kunyamula kukhale kosavuta komanso kotsika mtengo. Izi ndizothandiza makamaka m'mafakitale omwe amafuna kulongedza kwakukulu, monga chakudya ndi zakumwa, mankhwala ndi malonda apaintaneti.
Chinthu china chofunika kwambiri cha PP ndi kukana kwake mankhwala. Chimatha kupirira kukhudzana ndi ma acid, alkali ndi zinthu zina zowononga, zomwe zimapangitsa kuti chikhale choyenera kulongedza zinthu zomwe zingakhudze zinthu zotere. Izi ndizofunikira kwambiri makamaka m'mafakitale omwe amanyamula kapena kusunga mankhwala, monga makampani opanga mankhwala, magalimoto ndi zinthu zoyeretsera.
Katunduyu amamupangitsa kukhala woyenera kulongedza zinthu zomwe zimawonongeka monga chakudya ndi zakumwa, komanso zinthu zomwe ziyenera kusungidwa m'malo ozizira.
Chimodzi mwa zabwino kwambiri za PP ndi mphamvu zake zambiri komanso kulimba kwake. Chili ndi mphamvu zambiri zokoka, zomwe zikutanthauza kuti chimatha kupirira kupsinjika kwakukulu kapena kupsinjika chisanasweke. Izi zimatsimikizira kuti phukusili limakhalabe lolimba ngakhale litagwiritsidwa ntchito molakwika kapena kutumizidwa. Sizimakhudzidwanso ndi kugwedezeka, kotero sichingasweke kapena kusweka ngati chagwetsedwa kapena kugwedezeka.
Kuwonjezera pa makhalidwe ake enieni, zipangizo za PP zimadziwikanso ndi makhalidwe ake abwino kwambiri owoneka bwino. Ndi zowonekera bwino, zomwe zimathandiza ogula kuwona mosavuta chinthucho mkati mwa phukusi. Izi ndizofunikira kwambiri m'mafakitale komwe kukongola kwa mawonekedwe ndikofunikira, monga zodzoladzola ndi mafakitale osamalira anthu. Zipangizo za PP zimakhalanso zosinthasintha kwambiri ndipo zimatha kupangidwa m'mawonekedwe ndi kukula kosiyanasiyana. Kusinthasintha kumeneku kumapangitsa kuti ikhale yoyenera kugwiritsa ntchito mitundu yosiyanasiyana ya ma CD, kuphatikizapo mabotolo, ziwiya ndi matumba. Zitha kupangidwa mosavuta m'mawonekedwe ovuta ndipo zimatha kusinthidwa kuti zikwaniritse zofunikira zinazake zomangirira.Zipangizo za PP nazonso zimatha kubwezeretsedwanso komanso zimakhala zotetezeka ku chilengedwe. Zitha kusungunuka ndikusinthidwanso kukhala zinthu zatsopano, kuchepetsa zinyalala ndikuchepetsa kufunikira kwa zipangizo zatsopano zopangira.
Kubwezeretsanso zinthu za PP kumathandiza kusunga chuma ndikuchepetsa kugwiritsa ntchito mphamvu, zomwe zimapangitsa kuti zikhale zosankha zokhazikika pakulongedza. Ponseponse, zinthu za PP zimapereka zabwino zambiri pakugwiritsa ntchito ma CD. Chilengedwe chake chopepuka, kukana mankhwala ndi chinyezi, mphamvu zambiri komanso kulimba, mawonekedwe abwino kwambiri, komanso kubwezeretsanso zinthu zimapangitsa kuti zikhale zosinthika komanso zosawononga chilengedwe. Zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndipo zakhala gawo lofunikira kwambiri pamakampani opanga ma CD.
