Bokosi lopindandi chotengera chofunikira choyikamo chomwe chimagwiritsidwa ntchito kunyamula ndi kusungira katundu. M'zaka zaposachedwa, matabwa a thovu a polypropylene agwiritsidwa ntchito kwambiri popanga mabokosi. Polypropylene foam board ndi yopepuka, yolimba, yosalowa madzi, komanso imasunga chinyezi, zomwe zimapangitsa kukhala chinthu choyenera kupanga mabokosi opinda.
Kugwiritsa ntchito kwapolypropylene foam boardm'mabokosi opinda amapereka mabokosi opinda kuti atetezedwe kwambiri. Kuchita kwake kwabwino kwambiri kumateteza katundu kuti asawonongeke panthawi yamayendedwe, makamaka pazinthu zosalimba. Kuphatikiza apo, matabwa a thovu a polypropylene amakhalanso ndi zinthu zabwino zotchinjiriza kutentha, zomwe zimatha kusunga kutentha kwa katundu kukhazikika pamlingo wina, ndipo ndizoyenera kunyamula katundu wofunikira kuti asunge kutentha.
Kuphatikiza pa zinthu zoteteza, matabwa a thovu a polypropylene amakhalanso ndi processability yabwino komanso mawonekedwe, ndipo amatha kusinthidwa malinga ndi kukula ndi mawonekedwe a mabokosi opindika, ndikupanga mabokosi opindika kukhala osinthika komanso osiyanasiyana. Nthawi yomweyo,matabwa a polypropylenenawonso ndi ochezeka ndi chilengedwe, akhoza kubwezeretsedwanso komanso amakwaniritsa zofunikira za anthu amakono kuti akhale ndi chitukuko chokhazikika.
M'magwiritsidwe ntchito,mabokosi opindazopangidwa ndi matabwa a thovu a polypropylene amagwiritsidwa ntchito kwambiri muzakudya, mankhwala, zinthu zamagetsi ndi mafakitale ena. M'makampani azakudya, mabokosi opindika atha kugwiritsidwa ntchito ponyamula ndi kusunga masamba, zipatso ndi zinthu zina zaulimi. Makhalidwe awo osagwirizana ndi chinyezi komanso osalowa madzi amatha kukhalabe ndi thanzi labwino. M'makampani opanga mankhwala, mabokosi opindika amatha kugwiritsidwa ntchito kunyamula ndi kunyamula mankhwala, zida zamankhwala ndi zinthu zina kuti zitsimikizire kukhulupirika kwazinthu komanso chitetezo chaukhondo. M'makampani opanga zamagetsi, mabokosi opindika atha kugwiritsidwa ntchito kulongedza ndi kunyamula zinthu zamagetsi, zida zolondola ndi zinthu zina kuti ziteteze zinthu kuti zisagwe kugwedezeka komanso kugundana.
Ambiri, ntchito yamatabwa a polypropylenem'munda wa mabokosi lopinda wabweretsa mwayi chitukuko latsopano makampani ma CD. Kuchita kwake kwabwino kwambiri komanso kuthekera kogwiritsa ntchito kwakukulu kwapangitsa mabokosi opinda kuti agwiritsidwe ntchito kwambiri m'mafakitale osiyanasiyana, kupereka chitetezo chotetezeka komanso chodalirika pamayendedwe ndi kusungirako katundu. Ndi chitukuko chosalekeza chazachuma komanso kuchuluka kwazinthu zomwe anthu amafuna pamtundu wazinthu komanso kuteteza chilengedwe, mabokosi opindika opangidwa ndi matabwa a thovu a polypropylene adzagwiritsidwa ntchito kwambiri ndikulimbikitsidwa mtsogolo.
