AQUAPAL 9573F is a UV-active water-based adhesive engineered for side seam applications in bag, sack and envelope production. This specialised formulation bonds difficult liner papers and coated boards whilst providing UV detection capability for quality control systems, with high penetration characteristics and resistance to drying on nozzle tips.
The white UV-active formulation enables automated quality inspection systems to verify adhesive presence and placement across production.
Coated papers and clay-coated boards present challenges for water-based adhesives due to their low porosity and surface treatments. AQUAPAL 9573F has been formulated specifically to penetrate these surfaces sufficiently to create reliable bonds whilst maintaining the clean running characteristics needed for continuous production on both bag and envelope manufacturing lines.
The UV-active properties allow manufacturers running automated inspection systems to verify that adhesive has been applied correctly to every product. The formulation fluoresces under ultraviolet light, allowing inspection systems to verify adhesive presence and placement without affecting the visual appearance or performance of the finished product. This reduces the risk of defective products reaching customers and supports quality management systems that require documented verification of critical process steps.
Resistance to drying on nozzles reduces downtime and maintains consistent application, particularly valuable in intermittent application scenarios. The rheology has been optimised for precise bead application through roller, spray or nozzle systems. This precision reduces adhesive waste, minimises squeeze-out that can cause blocking or jamming, and supports tight tolerances needed for modern designs with windows and speciality features.
AQUAPAL 9573F is formulated for side seam bonding applications where quality verification and difficult substrates are involved. Side seam adhesives bond the overlapping paper layers that form the body of bags, sacks and envelopes, creating the structure that will be folded and sealed. The UV-active additive enables quality control without affecting product appearance or performance.
The formulation provides good wet tack for immediate bonding during folding operations whilst developing high ultimate bond strength as the adhesive dries. The white colour provides good contrast for visual quality control during application, whilst remaining unobtrusive on finished products. The low viscosity supports fine-line application methods that minimise adhesive consumption whilst maintaining adequate bond strength. The adhesive provides good open time for positioning whilst developing adequate grab for production flow.

Handle according to standard water-based adhesive safety protocols. Wear protective gloves and safety glasses during handling and application. Maintain adequate ventilation in application areas. Avoid prolonged skin contact and wash affected areas thoroughly with soap and water if contact occurs. The UV-active component does not create additional safety concerns beyond standard adhesive handling. Keep away from food, drink, and animal feeding stuffs. Consult the Safety Data Sheet for complete safety information, including first aid measures and environmental precautions. Store in original containers and dispose of waste according to local regulations.
Apply AquaPAL 9573F at room temperature through properly maintained side seam application equipment. Clean equipment promptly with warm water before adhesive dries. UV-inspection systems should be calibrated according to manufacturer specifications to detect the fluorescent additive reliably. For UV inspection system integration or application optimisation, technical support is available.
