The Top and Bottom labels are placed on the top and the bottom of a package. This is the application of two separate labels. An example would be identification of a product on the top and a bottom label with nutritional values and ingredients.
The C-Wrap label is a panel wrap that stretches from the top, to the front, to the bottom of a container. These labels generally provide product information, branding and pricing information. This particular type of label is sometimes referred to as tamper evident labeling, because it is easy to identify if a package has been opened.
