12mic CLEAR/HOLOGRAPHIC pet with primer coating for good printinga and coating

The application of primer coating to PET film is a crucial process that solves adhesion problems through a combination of chemical and physical mechanisms. Its core value lies in improving adhesion and process compatibility, supporting the high-quality application of PET in printing, packaging, electronics, optics, and other fields.

PET film primer coating is a key process that solves the adhesion problem through a combination of chemical and physical effects. Its core value lies in improving adhesion and process compatibility, supporting the high-quality application of PET in printing, packaging, electronics, optics, and other fields.
Main Functions:
Significantly improved adhesion: Solves the "difficult adhesion" problem of PET, preventing inks, adhesives, and functional coatings from peeling off easily. Adhesion tests can achieve a zero rating (no peeling with tape).
Optimized subsequent process compatibility: Improves printability, allowing ink to spread evenly and resulting in vibrant colors; enhances lamination strength, ensuring the stability of PET composite with other films, paper, and metal foils.
Enhanced durability and protection: Improves the coating's water resistance, chemical resistance, temperature resistance, weather resistance, and anti-aging properties, reducing the impact of environmental factors on PET products.
Maintains substrate characteristics: High-quality primers are transparent and have low haze, without affecting the original advantages of PET such as gloss, transparency, and mechanical strength.
Common Applications: Covering multiple industries
PET film treated with primer is widely used in applications requiring strong adhesion and high stability:
Printing and packaging: Food/pharmaceutical packaging films, labels, hot stamping films, transfer films, etc. Compatible with solvent-based, water-based, and UV inks, improving print clarity, abrasion resistance, and weather resistance, preventing pattern peeling.
Composite packaging and lamination: Vacuum metallized PET film, PET/PE/PET composite film, self-adhesive materials. The primer enhances the bonding strength between PET and the aluminum layer, adhesive layer, and other films, preventing delamination and bubbling.
Functional films and electronics: Optical films (such as diffusion films, hardening films), PET for flexible circuit boards, battery separators. The primer improves the adhesion of functional coatings (such as UV curing layers, conductive coatings), ensuring optical performance and usage stability.
Other industrial applications: PET hot stamping foil, decorative films, release films, etc., improving compatibility with heat transfer adhesives and back adhesives, and enhancing product durability.
