Seeing stripes show through your glued box wraps?  Well, that certainly won't make for a clean finished product. Chances are if you're reading this post, you've experienced glue bleeding through your substrates. 

Whether you're using liquid glue or animal glue (hide glue), bleeding can happen if the glue is not applied correctly. Glue bleeding is a result of applying more glue than recommended to your substrates. Yes, you heard us right. We are selling glue and at the same time telling you to apply LESS of it.

Here's why...

Applying too much glue can cause several issues for your production. As we've mentioned, you may begin to experience glue bleeding through your substrates. This will not only be frustrating, but also cost your team money in rejected finished boxes.

You may also start to experience warping. These glue formulas are water-based, and introducing more water than necessary could cause your substrates to curl, making them difficult to bond properly.  

Increasing the glue application amount beyond recommended settings will also start to create a mess on your equipment, both at the roller and the belt. The last thing you want to do is stop production to constantly clean your machine. Over applying glue will force your team to clean the equipment more often. 

Finally, applying too much glue is a waste of your money and raw materials! You could end up running through your glue twice as quickly if you're applying two times the recommended glue film thickness. 

What's the easiest way to make sure you're applying the recommended amount of glue? We recommend that you use a mil depth gauge. This little tool will help you to accurately measure the glue film thickness being applied at the roller, and help ensure you're not adding more than needed or recommended. 

Not sure how much glue you should be applying? Reach out to our technical team. We would be happy to go over the technical specification for your glue.
