As an important material that combines packaging and promotional functions, printed films have become a key focus for industry optimization in terms of both print quality and durability. In recent years, innovative advancements in surface treatment technologies have provided crucial support for enhancing the performance of printed films. Through the precise application of surface modification processes such as corona treatment, plasma treatment, and chemical grafting, it is possible to significantly increase the surface tension of film materials and improve their adhesion to printing inks and composite adhesives.

Industry test data show that the printed film products, after optimized surface treatment processes, achieve a print adhesion rating of 4B or higher, effectively addressing common issues in packaging printing such as ink shedding and layer separation. Meanwhile, the refined control of the surface treatment process also enhances the scratch resistance and weatherability of the printed films, ensuring that the printed patterns remain clear and intact throughout storage and transportation. During production, companies precisely control the treatment intensity and duration to tailor the surface treatment specifically for different types of printed films, making them compatible with a variety of substrates including PE, PP, and PET.

In terms of application areas, the upgraded printing films are widely used in packaging for industries such as food, daily chemicals, and gifts. While enhancing the aesthetic appeal of product packaging, they also strengthen brand communication effectiveness. With the development of the e-commerce industry, the use of printing films in express delivery packaging and e-commerce gift box packaging has been steadily increasing, placing higher demands on both exquisite print quality and tear resistance. In the future, the integration of surface treatment technologies with digital printing technologies will further enhance the personalized customization capabilities and production efficiency of printing films.

The heat-resistant heat-sealing film technology is well-established and suitable for high-temperature processing and sterilization requirements.

Environmentally friendly inks are becoming widespread in the printing film sector, driving green development in the packaging industry.
