Manufacturer Special Water-based Paper Plastic Water-based Manual Sealing Glue
Manual Sealing Glue is a water-based, environmentally friendly adhesive, typically copolymerized from acrylate emulsion, tackifying resin, and various additives. Its main characteristics are non-toxicity, non-irritating odor, non-flammability, and stable chemical properties.
Q1: Can I use manual sealing glue to bond UV-varnished boxes?
A: It depends on the specific product formula. Standard water-based manual sealing glues often specify that they are not suitable for UV-varnished surfaces. However, specialized "UV Sealing Glue" products are available that are formulated with enhanced adhesion for such surfaces. If you need to bond UV-varnished boxes, we recommend selecting a glue specifically designed for UV applications and conducting a test first.
Q2: What should I do if I apply too much glue and it squeezes out after pressing?
A: Glue squeeze-out typically occurs because the adhesive hasn't dried sufficiently before pressing. To prevent this, extend the open time (waiting period) after application to 5-8 minutes, allowing the glue to become tacky and semi-transparent before bonding. If squeeze-out occurs, wipe away the excess immediately with a damp cloth. Ensure bonded products are stored separately to avoid sticking to each other.
Q3: The bond seemed strong right after gluing, but failed after a few days. Why?
A: This issue is often related to poor "holding power" or inadequate aging resistance. Possible causes include: the adhesive contains plasticizers that migrate into the paper substrate over time, causing the glue line to become hard and brittle; or the adhesive itself has poor aging stability. To avoid this, choose high-quality adhesives from reputable suppliers.
