Special White Latex Glue for Gluing Machine | Paper Mounting & Laminating Glue
Fine mounting glue is a water-based, environmentally friendly adhesive specifically designed for bonding laminated films (BOPP/PP), specialty papers, leather, and PVC to rigid substrates such as chipboard, greyboard, and MDF. It is widely used in the production of high-end gift boxes, liquor boxes, jewelry cases, hardcover books, and other premium packaging applications
Q1: What is the difference between fine mounting glue and ordinary white glue (PVA)?
A: Ordinary white glue (PVA) cannot effectively bond laminated papers (e.g., BOPP/PP film) due to the film’s low surface energy. Fine mounting glue is specially formulated with modified acrylics to provide strong adhesion to such films. Additionally, it offers a longer open time, making it more suitable for manual box-making and large-format mounting, while also providing better heat and cold resistance.
Q2: Why does my mounted product show bubbles or “snowflake” spots after bonding?
A: “Snowflake” spots are usually caused by excessive spray powder on the printed paper or insufficient glue application. You can try increasing the coating weight or wiping off excess spray powder before gluing. Bubbles may occur if the ink layer is not fully dried, the laminating roller temperature is too high, or the adhesive has started to skin over before bonding. Ensure proper drying and apply glue evenly.
Q3: The glue seems to dry too quickly – why is that, and how can I fix it?
A: Fast drying (short open time) is typically caused by: (1) high workshop temperature or strong airflow, (2) too thin an adhesive coating, or (3) a high-solid-content formula. To extend open time, increase the coating weight, reduce air movement, or consult your supplier for a slower-drying version suitable for your conditions.
