Q1: What is the primary function of blister pack backing adhesive in packaging?
A: It creates a permanent bond between the plastic blister cavity and the paperboard/cardboard backing, ensuring that the product remains securely sealed and protected throughout handling, shipping, and consumer use. This prevents accidental opening and maintains package integrity.

Q2: What types of materials is this adhesive compatible with?
A: It is formulated to adhere to common blister films (PVC, PET, PP, Aclar) and paper-based backings (coated or uncoated cardboard). For optimal performance, surface compatibility should be tested with specific material combinations and printing inks.

Q3: What are the key application and curing considerations?
A: Apply via roller coater, spray, or slot-die system in a controlled thickness. Adhesion strength depends on uniform application, adequate pressure during lamination, and proper drying/curing (often through heat activation or air drying). Production speed, temperature, and humidity may affect bond development and should be optimized through testing.
