Q1: What are the advantages of applying blister coating via screen printing compared to conventional methods?
A: Screen printing allows for precise, localized coating application—ideal for spot sealing, custom patterns, or selective barrier enhancement. It enables greater control over film thickness and minimizes material waste, offering design flexibility for specialty packaging that cannot be achieved with full-surface coating techniques.

Q2: Is this coating compatible with common blister films and paperboard substrates?
A: Yes. The formulation is engineered to adhere strongly to standard blister films (PVC, PET) and paperboard surfaces used in packaging. However, pre-application testing is recommended to verify compatibility with specific material combinations and to optimize mesh selection, ink viscosity, and drying parameters for consistent results.

Q3: What are the key drying and processing requirements for screen-printed blister coatings?
A: Due to the typically thicker film applied via screen printing, adequate drying is essential. Forced air drying or low-temperature tunnel drying is recommended to ensure complete curing before thermoforming. Proper curing ensures optimal heat-seal strength, prevents blocking, and maintains coating integrity during subsequent converting steps.
