Peel tabs are widely used on booklet labels for curved surfaces. The idea is that they offer an easy way to get a finger under the tab to open the booklet. We sell against the peel tab as much as possible because we believe this advantage is marginal versus how much cost and time a peel tab takes.
Here are some of the disadvantages of peel tabs: (1) Peel tabs create an extra step in the process. After the booklet press sheets are printed, they must be sent to die cutting equipment to create the tabs which takes more time and costs more money. (2) Peel tabs cover between 15% to 25% of the peel up wing. Less exposed adhesive equals less stick to the liner. The opening wing of this type of booklet label (Lam to Liner) sticks directly to the carrying liner so it is weaker bond to begin with. If you need to serialize your label with a post print process that has a long web path with lots of turns, this makes it more likely that the label will delaminate and get caught in the rollers. The same is true when using label applicating equipment.
Don’t get me wrong, peel tabs are widely used, but at BCL, we are constantly looking for ways to reduce lead times and cost while maintaining a high level product. We believe eliminating the peel tab makes a lot of sense. One caveat– if you are not convinced, and you need a peel tab, we can do it for you, of course.
