1. Polymer Film Substrate:

The foundational material for deep-dyed films is commonly a polyester polymer film known for its durability, flexibility, and optical clarity.

2. Dyeing Process:

In the manufacturing of deep-dyed films, a crucial step involves saturating the polymer film with a specialized colored dye selected for its ability to withstand sunlight exposure and maintain color durability.

3. Coating and Laminating:

Post-dyeing and additional coating processes may enhance film performance. For instance, a scratch-resistant coating may be added for improved durability, and laminating layers might increase strength or provide UV protection.

4. Curing or Fixing the Dye:

To ensure color stability, the dyed film undergoes a curing or fixing process, which is crucial for preventing color fading or bleeding, particularly in sunlight.

5. Quality Control:

Throughout the manufacturing process, rigorous quality control measures are implemented, testing optical properties, thickness, adhesion strength, and other relevant characteristics of the deep-dyed film.

6. Cutting and Packaging:

After passing quality control, the film is typically cut into sheets or rolls of the desired size, ready for packaging and distribution.
