Plural of bagging; the act of putting items into bags, or the material used for making bags.
From 'bag' plus the gerund/action suffix '-ing' (Old English '-ing', from Proto-Germanic), then pluralized with '-s.' The '-ing' form represents an action or process.
Bagging as a material—burlap and canvas bags—was so essential to commerce that 'baggings' became a specific category of industrial goods. Entire supply chains existed just for producing the bags themselves, which seems quaint now when plastic bags seem free and infinite.
