MpweyaChikwama cha DunnageNdi chida chatsopano komanso chosavuta chotetezera katundu, chokhala ndi PP ndi PE chopangidwa ndi pepala lopangidwa ndi kraft, cholimba komanso cholimba, mkati mwa thumba muli makamaka zigawo zitatu za PE zopangidwa ndi arch crowded membrane, valavu imodzi yosabwerera yopumira kapena yoyikidwa ndi gasi yokhala ndi mphamvu yothamanga, yopumira mpweya, yoteteza bwino magalimoto, chidebe kapena sitima kuti katundu agundane. Ngati matumba a mpweya akudzaza mokwanira malo pakati pa katunduyo, katundu wopangidwa ndi kugwedezeka amathandizira kulemera, kuyamwa kugwedezeka, kuteteza katunduyo ku kuwonongeka komwe kumachitika, kuposa china chilichonse chothandizira kudzaza zinthu, zotsatira zake zimakhala zabwino kuposa kugwiritsa ntchito thovu pulasitiki ndi zina zotero.

Chikwama cha mpweya chogwiritsidwa ntchito mu chidebe nthawi zambiri chimakhala ndi zigawo zitatu zazikulu: gawo lakunja, gawo lamkati, ndi valavu. Gawo lakunja limapangidwa ndi zinthu zolimba komanso zosabowoka, monga pepala la kraft, polypropylene yolukidwa, kapena kuphatikiza zonse ziwiri. Gawo lamkati nthawi zambiri limapangidwa ndi filimu ya polima yomwe imatha kupirira kuthamanga kwambiri ndikuletsa kutuluka kwa mpweya. Vavu, yomwe ili kumapeto kwa thumba la mpweya, imalola kutsika kwa mpweya ndi kutsika kwa madzi m'thumba.

Chikwama cha mpweya chikayikidwa bwino m'chidebecho, chimadzazidwa ndi mpweya wopanikizika pogwiritsa ntchito chida chapadera, kudzaza malo opanda kanthu ndikupereka chithandizo ndi kukhazikika kwa katunduyo panthawi yonyamula. Chikwamacho chikafika komwe chikupita, valavu imatha kutsegulidwa mosavuta kuti itulutse mpweya ndikutulutsa madzi m'chikwamacho, zomwe zimapangitsa kuti chikhale chosavuta kuchotsa ndikusunga kuti chigwiritsidwe ntchito mtsogolo.
