What are the tips for using hot melt adhesive for cardboard packaging

Hot melt adhesive is not unfamiliar to cardboard packaging, as it is not only efficient but also cost-effective. Some packaging adhesives, equipment options, and packaging techniques were used when applying hot melt adhesive;. This article helps you understand the technology of hot melt adhesive suitable for your cardboard packaging.

Conventional slotted cardboard box (RSC)

Use 1/8 inch beads approximately 1/2 inch from the edge of the flip cover to create durable cardboard boxes. Do you need extra high intensity? Use double beads. Use a T-shaped nozzle to easily apply double beads. Having a T-shaped nozzle is the most effective way to lay double beads and can provide you with the same results every time. However, if additional strength is required, you can use a standard nozzle and place two beads.

Easy Open Technology on RSC

Hot melt adhesive allows you to easily open cardboard boxes through various methods without sacrificing good sealing. These methods can easily reuse cardboard boxes. We recommend using 1/8 “beads to maintain the strength of the cardboard box. You can also use 1/16” beads, but it will reduce the strength of the cardboard box.

Fully Overlapping Carton (FOL)

The best effect can be achieved by placing 1/8 “beads on the front and 3 sides, or you can lay double beads. For single bead applications on FOL cartons, we found the L nozzle very convenient. If beads are needed, using a T-shaped nozzle is the simplest.

Hot melting point adhesive to save costs;

Upgrading your batch dispensing to include hot melt dispensing and stitching systems can save you a lot of money. Traditionally, hot melt adhesive is used to seal packaging with solid line dispensing, but this innovative process allows for a series of point and line dispensing, typically using 50% less adhesive.  

The upgrade package can be installed within three hours without the need for new cans or nozzles, and achieves more reliable and durable dispensing.
