You’re wearing a brand new pair of shoes when you step on a wad of chewing gum. You can feel the gum stretching up from the ground as you lift your foot, revealing a stringy mess. Isn’t it the worst?

In the world of packaging, industrial adhesives can behave in a similar way, which we refer to as “chewing gum failure.” If you’re seeing pop-opens in your plant, there’s a possibility it could be a chewing gum failure. Like chewing gum, the adhesive appears stringy and is visible on both sides of the substrate.   

What Causes “Chewing Gum Failure?”

There are a few reasons this type of case and carton failure might occur:

  1. The adhesive is too hot
  2. There’s too much adhesive
  3. The adhesive is too slow
