One general observation that can be made is that many cannabis product containers are small.
For example, oils, tinctures, and topicals can be sold in bottles of just a few ounces. Depending on the type of edible, they can be packaged in small or individual packs and containers.
Other cannabis products, like flowers and concentrates, tend to be sold in packaging for small quantities due to regulations.
Smaller packaging does not have room for multiple labels so applying one label is a more ideal option.
Inkjet printers are able to customize labels in multiple sizes, some as small as 1.5 inches wide, allowing businesses to accommodate changes to regulations and designs as they occur.
