How to use hot melt adhesive particles to firmly stick business cards after laminating? Step by step operation guide

Answer directly

The surface of laminated business cards is dense and has low polarity, making it easy to “fake stick” when directly glued. The key is to choose the right adhesive type, treat the surface well, control the temperature and pressure, in order to stick firmly.

Operating Steps

1. Choose adhesive:Used for adhesive film and PVCHot melt adhesive granulesPrioritize high initial adhesion models.
2. Surface TreatmentGently wipe off the release agent with alcohol or polish locally to increase roughness.
3. Temperature controlled melting:Glue according to the manufacturer’s range to avoid excessive carbonization and low leveling.
4. Coating and pressing:The glue line is evenly applied and pressed together for 3-5 seconds during the opening time while still hot.
5. Cooling and shaping:Let it cool down before cutting to prevent displacement.

Sunlifehot melt adhesiveThere are models specifically designed for laminated surfaces, and Guangzhou Sunlife Trading can provide small sample adhesion testing. Before mass production, it is necessary to conduct a tensile test to confirm that there is no delamination before proceeding to the production line.

Frequently Asked Questions

Q: Why did it open again after being pressed down?If the opening time is missed or the pressure is insufficient, adjust the pressing timing.

Q: Can ordinary glue be used for gluing?The adhesion of the film is poor, and the special adhesive is more secure.
