What are the surface treatments of white TPU film?

The surface treatment technology of white TPU film is an important means to improve its performance and application range. These processing technologies mainly include:

1. Surface coating: Coating a layer of special materials, such as polyurethane, silicone, etc., on the surface of the TPU film to enhance its wear resistance, anti-pollution or provide a specific surface texture.

2. Surface printing: Print patterns or text on the surface of the TPU film through screen printing or digital printing technology to increase the identification and aesthetics of the product.

3. Surface embossing: A specific texture or pattern is formed on the surface of the TPU film through the embossing process, which not only increases the aesthetics but also provides anti-slip function.

4. Surface frosting: Through frosting treatment, the surface of the TPU film has a matte effect, reducing light reflection, and is suitable for products that require low-key gloss.

5. Surface plating: Electroplating on the surface of the TPU film can give it a metallic luster and increase the high-end feel of the product.

6. Surface heat treatment: The surface structure of the TPU film is changed through heat treatment to improve its heat resistance and chemical resistance.

7. Surface laser treatment: Using laser technology to perform fine processing on the surface of the TPU film, complex patterns and fine text can be produced.

8. Surface chemical treatment: The surface of the TPU film is treated with chemical reagents to improve its adhesion, dyeability or biocompatibility.

These surface treatment technologies can be used individually or in combination to achieve specific performance requirements and appearance. Different processing methods are suitable for different application scenarios, such as outdoor products, shoe materials, medical supplies, etc.
