The silicone primer film can be tightly adhered to silicone products without separation or detachment

PET (Polyethylene Terephthalate) rigid films are widely used in packaging, electronics, and other industries due to their excellent properties. Here are the key characteristics of PET rigid films:

1. **High Strength and Durability**: PET films are known for their high tensile strength and durability, making them resistant to tearing and puncturing.

2. **Transparency**: PET films are highly transparent, allowing for excellent visibility of the packaged product. This makes them ideal for applications where product visibility is important.

3. **Chemical Resistance**: PET films are resistant to many chemicals, including oils, greases, and solvents, which makes them suitable for packaging a wide range of products.

4. **Thermal Stability**: PET films have good thermal stability and can withstand a wide range of temperatures. They are often used in applications that require heat sealing or exposure to high temperatures.

5. **Barrier Properties**: PET films provide excellent barrier properties against gases (such as oxygen and carbon dioxide) and moisture, which helps in preserving the freshness and extending the shelf life of packaged products.

6. **Dimensional Stability**: PET films maintain their shape and size under various conditions, including changes in temperature and humidity. This makes them reliable for precision applications.

7. **Lightweight**: Despite their strength and durability, PET films are lightweight, which helps in reducing transportation costs and makes them easy to handle.

8. **Recyclability**: PET is a recyclable material, and PET films can be recycled, contributing to environmental sustainability.

9. **Printability**: PET films have a smooth surface that is suitable for high-quality printing, making them ideal for packaging that requires branding and labeling.

10. **Electrical Insulation**: PET films have good electrical insulation properties, making them useful in electronic applications such as insulating films for capacitors and other components.

These properties make PET rigid films versatile and suitable for a wide range of applications, including food packaging, medical packaging, electronics, and more.
