Four Fast Facts About Case & Carton Sealing

1) Hot melt is the most popular bonding adhesive when it comes to case and carton sealing.

2) It’s about sealing the flaps.

Application of the adhesive is typically an end of the line process and involves the adhesive being applied at an elevated temperature to open flaps, which are then placed in contact with the remaining flaps and compressed to form the final bond. Often times the adhesive is applied to a minor flap, which is then bonded to a major flap.

3) In your environment, pay attention to the following factors:

Full adhesive equipment melt tanks (stable application temperature)

Glue bead patterns (length, width,)

Air and surface (substrate) temperatures

Application speeds (ranging from beads for medium speeds, to dots applications for precise, high-speed)

Carton sizes (big or small)

Set times (can be a function of amount of adhesive used)

4) How do you know if you’ve done it right?

In most cases, if you try and open the carton and the corrugated flap shreds apart, you’re not creating the optimal experience for recipient. Most people prefer a box or carton that maintains its integrity during shipping and receiving, but also easily opens when the flaps are pulled apart. But if you need a seal that’s harder to open than Fort Knox, by all means go for it!
