What are the types and application areas of PET silicone oil films?

PET silicone-coated films can be primarily categorized based on silicone coating application and functional characteristics, with common types as follows:

By Silicone Coating Application

- Single-sided silicone-coated film: Silicone is applied to only one side of the PET substrate, while the other side retains the original PET film properties (such as inherent tackiness or printability). Widely used as release paper for adhesive tapes, temporary protective layers for electronic components, etc.

- Double-sided silicone-coated film: Both sides are coated with silicone, providing enhanced overall anti-adhesion properties. Suitable for scenarios requiring double-sided separation, such as preventing interlayer adhesion during certain composite material production processes.

By Application Characteristics

- Low-release silicone-coated film: Features a silicone layer with minimal release force, facilitating easy separation from laminated materials. Ideal for applications requiring low peel strength, such as temporary fixation of precision electronic components.

- Medium Release Force Silicone Film: Features moderate release force with balanced properties, offering broad applicability. Commonly used as a production carrier for standard tapes, labels, and similar products.

- High release force silicone oil film: Features strong release force and relatively firm adhesion to laminated materials, requiring significant force to peel off. Suitable for scenarios requiring long-term temporary fixation or load-bearing, such as processing aids for certain industrial components.

Additionally, further classification may be based on PET substrate thickness, transparency, and other factors to accommodate specific application requirements.

PET silicone release film boasts exceptional anti-adhesion properties, stability, and substrate characteristics, making it widely applicable across various sectors, primarily in the following scenarios:

Electronics Industry

- Release carrier for tapes/protective films: For double-sided tapes, conductive adhesives, and dust-proof protective films used in electronic devices like smartphones and computers. During production, the film's anti-adhesion properties enable molding and peeling while preventing adhesion contamination.

- Processing aid for electronic components: Used to isolate surfaces during temporary fixation and handling of precision parts like flexible circuit boards and display modules, preventing scratches or contamination.

Packaging Sector

- Premium packaging liners: Employed in cosmetics, luxury goods, and precision instrument packaging to prevent adhesion between packaging materials and product surfaces while safeguarding product aesthetics.

- Food Packaging Support: Used in premium packaging for certain specialty foods (e.g., chocolates, candies) to isolate packaging paper from food items or serve as temporary carrier material (must comply with food contact standards).

Printing and Laminating Industry

- Specialized Printing Processes: Functions as a release layer or transfer carrier in techniques like hot stamping and UV printing, ensuring precise pattern transfer and reducing ink adhesion.

- Composite Material Production: Used for interlayer separation in multi-layer composites (e.g., plastic film/fabric laminates) to prevent premature adhesion during manufacturing and ensure composite precision.

Medical and Hygiene Sector

- Medical Product Support: Serves as a release layer for certain medical tapes and dressings, or as packaging separation material for disposable medical supplies, meeting residue-free and hygienic stability requirements.

Industrial Manufacturing Sector

- Mold or Component Protection: Applied to metal or plastic molds during temporary storage or processing to prevent rust and dust contamination. Also used for surface protection of certain industrial components to avoid friction damage during transportation.

Different types of PET silicone release film (e.g., single-sided/double-sided, varying release forces) are flexibly selected based on specific application requirements.
