Q1: What are the key benefits of using a water-based (aqueous) blister primer versus solvent-based alternatives?
A: This aqueous primer significantly reduces VOC emissions and odor, improves workplace safety, and supports environmental compliance and sustainability goals. It maintains high performance in sealing and matte finishing while offering easier cleanup and compatibility with eco-sensitive production environments.

Q2: How does the matte finish affect printability or post-processing on blister cards?
A: The matte surface provides an excellent, glare-free substrate for printing, ensuring sharp text and vivid graphics without reflection interference. It is fully compatible with standard offset, flexo, or digital printing processes applied before blister sealing, and does not hinder die-cutting, embossing, or other converting steps.

Q3: Are there specific drying or application considerations for water-based primers on paperboard?
A: Due to the water-based formulation, efficient drying is essential to prevent substrate warping or blocking. The use of IR and/or hot-air drying is recommended to ensure complete water evaporation and proper film formation before thermoforming. Coating weight and uniformity should be controlled to achieve consistent matte appearance and sealing strength.
