Hot Melt Packaging Techniques

Hot melt adhesives are an economical way to bond multiple substrates and can be applied using many different types of applicators. They can be extruded, rolled, or sprayed either manually or automated with a hand, spray, ribbon, or roll applicator. They are typically used in many applications, including packaging. 

Check out our short descriptions (along with the graphic) to get an idea of what technique is suitable for your packaging application.

Regular Slotted Container (RSC): This is the most common. For the Regular Slotted Container, all of the flaps have the same length, and the two outer flaps are one-half the container’s width so they can meet in the center. They always require glue, tape, or staples to close. Because of this highly efficient design, there is little manufacturing waste. Create durable cartons by using 1/8″ adhesive beads laid approximately 1/2″ from the flap edge. Need extra high strength? Use twin beads.

The Full Overlap (FOL): carton is a heavy-duty box for heavy-duty purposes. The flaps on this style extend to the opposite side of the box when folded, completely overlapping each other, adding stacking and structural strength to the box—this makes it ideal for storing or shipping heavy items. The best results can be achieved by laying a 1/8″ bead on the front side, on three sides, or you can apply a double bead.
