Which position should be glued with hot melt adhesive particles for hanging tags and cards? A case study of improving the yield of a clothing accessory factory

Background: Hang tags are always glued in logistics

A clothing accessory factory produces brand tags and hanging cards, using Hot melt adhesive granules Stick the cardboard and rope buckle firmly. The complaints are concentrated on: about 6% of the hang tags have peeled off after transportation, and customers have failed to scan the code for price verification.

The problem with the original method

• Glue is applied to the center of the rope buckle seat, with the force point deviating, making it easy for the entire piece to fall off when torn;
• The coating amount fluctuates, with excess causing glue to overflow and dirty the surface, and less causing virtual adhesion;
• The surface of the cardboard is covered with film, and ordinary glue has poor penetration.

Renovation Plan

Guangzhou Sunlife trade technician suggests that the adhesive should be applied to the “two ear positions” of the rope buckle seat instead of the center, so that the tension can be dispersed along the ear positions; Replace with specialized granules with high initial adhesion and adhesive film surface; The coating amount is fixed at 0.25 g/point and controlled by a dispensing valve. Sunlife hot melt adhesive provides a comparison sample for bonding laminated cardboard, confirming that the damaged surface of the new material is on the paper fiber.

Result

Stick to the right position and select the right adhesive, which is more effective than simply adding the right amount of adhesive.
