Q1: Why is a primer necessary for BOPP film before coating or printing?
A: BOPP film inherently has low surface energy and chemical inertness, making it difficult for inks and coatings to adhere directly. This primer modifies the surface chemistry, significantly improving wettability and creating active bonding sites to ensure strong, permanent adhesion and prevent peeling or delamination.

Q2: How is this primer typically applied in the production process?
A: It can be applied via standard coating methods such as gravure, flexo, or roll coating, often in-line before printing or finishing. For optimal results, uniform coverage and controlled drying (thermal or UV-based) are essential to prepare the surface without affecting film properties or causing blocking.

Q3: What performance benefits does it offer in final applications?
A: By ensuring reliable adhesion, it enhances print quality, scratch resistance, and durability of the finished product. It is critical for flexible packaging, high-end labels, and industrial films that undergo mechanical stress, humidity, or chemical exposure, ultimately improving product lifespan and performance consistency.
