What properties are enhanced by chemically treating metallized PET films?

Nov 15,2023

Chemical treatments on metallized PET films enhance several important properties, making them even more versatile and useful in various applications.
1. Improved Adhesion: Chemical treatment enhances the adhesion between the metallized layer and the PET film substrate. This ensures better bonding, preventing delamination or peeling that can occur under stressful conditions. The enhanced adhesion enables the films to withstand rigorous processes like lamination, coating, or printing without compromising their integrity.
2. Enhanced Barrier Properties: Metallized PET films already exhibit excellent barrier properties against oxygen, moisture, and light. Chemical treatments further improve these barrier properties, making the films even more resistant to external elements. This enhancement ensures better preservation of sensitive contents and protects against degradation, extending the shelf life of products in applications such as packaging for food, pharmaceuticals, or electronics.
3. Increased Chemical Resistance: Chemical treatments enhance the resistance of metallized PET films to various chemicals, including solvents, oils, and cleaning agents. This improved chemical resistance makes them suitable for applications exposed to such substances, including industrial environments or household products.
4. Superior UV Protection: Chemical treatment helps enhance the UV resistance of metallized PET films, making them highly effective in shielding against harmful ultraviolet (UV) radiation. This property is crucial in applications where UV protection is essential, such as window films, automotive interiors, or outdoor signage.
5. Enhanced Heat Resistance: Chemical treatments can also enhance the heat resistance of metallized PET films, allowing them to withstand higher temperatures without compromising their structural integrity. This property is particularly valuable in applications where the films may be exposed to high temperatures during processing or use.
6. Improved Electrical Insulation Properties: The chemical treatment of metallized PET films can enhance their electrical insulation properties, making them more suitable for applications requiring insulation against electrical currents. This property is valuable in industries such as electronics, where films are used in capacitors, batteries, or circuit boards.
Overall, chemical treatments applied to metallized PET films improve their adhesion, barrier properties, chemical resistance, UV protection, heat resistance, and electrical insulation capabilities. These enhancements pave the way for a wider range of applications, providing industries with more reliable and efficient solutions.
