Hot melt adhesive is no stranger to packaging, not only is it efficient, but cost effective. There are a few common packaging techniques that are used when applying hot melt. Check out our short descriptions and images above to get an idea on what technique is right for you packaging application.
Regular Slotted Cartons (RSC)
Create durable cartons by using a 1/8" adhesive beads laid approximately 1/2" from the flap edge. Need extra high strength? Use twin beads. Easily apply twin beads using a T shaped nozzle. Having a T nozzle is the most efficient way to lay twin beads and gives you the same results every time. However, you can use a standard nozzle and just lay two beads if extra strength is needed.
Easy Open Techniques on RSC
Hot melt allows you several ways to make a carton easy to open without sacrificing a good seal. These methods make it easy to reuse the carton. We recommend using a 1/8" bead to maintain carton strength. You can also use 1/16" bead, but the carton strength will be reduced.
Full Overlap Cartons (FOL)
The best results can be achieved by laying a 1/8" bead on the front side, on 3 sides or you can lay a double bead. For single bead applications on FOL cartons we find an L nozzle is very convenient. If a double bead is required, it's easiest to use a T nozzle.
