Agafuka k'umwuka gashyirwa mu gikoresho ni ubwoko bw'ibikoresho byo gupfunyikamo bikoreshwa mu gufata no gufunga imizigo mu bikoresho byo gutwara imizigo mu gihe cyo gutwara imizigo. Kagenewe kuzuza ahantu hadafite ibintu cyangwa icyuho kiri hagati y'ibicuruzwa biri mu gikoresho, bikarinda ko bihinduka cyangwa ngo bigende mu gihe cyo gutwara imizigo.

Izi sakoshi ubusanzwe zikozwe mu bikoresho bikomeye kandi biramba nka polyethylene cyangwa polypropylene, kandi zifite valve ituma zishobora guhumeka byoroshye hakoreshejwe umwuka ufunze. Iyo zimaze guhumeka, zishyira igitutu ku mizigo no ku nkuta z'ikigega, bigatuma habaho uburyo bwo gukamura ibintu bitunguranye n'imitingito mu gihe cyo kubitwara.

Amasashe yo mu bwoko bwa "container" akoreshwa cyane mu nganda zikoresha uburyo bwo kohereza ibicuruzwa mu masanduku, nko gutwara imizigo, gutwara imizigo, no gukora. Agira uruhare runini mu kwemeza ko ibicuruzwa bigera aho bigomba kugera bimeze nk'uko byari byapakiwe.

Gukoresha imifuka ya dunnage bifasha mu kunoza umwanya w’ibikapu, kugabanya ibyago byo kwangirika kw'ibicuruzwa, no kunoza imikorere y'ubwikorezi muri rusange. Biza mu bunini butandukanye kandi bikagira imiterere itandukanye kugira ngo bihuze ingano n'ubwoko butandukanye bw'imizigo ya bikapu.
