Abrasion refers to the scuffing, wearing, or scratching of a part against its package or external surfaces. In the context of packaging, abrasion describes the damage caused by friction, which can occur during handling, transportation, or storage. This friction can lead to the deterioration of both the product and its packaging, compromising the integrity and appearance of the item. Effective packaging design aims to minimize abrasion by using protective materials and cushioning to reduce friction and safeguard the contents.
