Anti-block PET Sheet
Intro of Anti-block PET Sheet
Anti-block PET sheet is a specially treated polyethylene terephthalate (PET) film or sheet, mainly used to prevent blocking of materials when stacking or winding. Anti-blocking technology is usually implemented in two ways:
External Silicone Coating: Coat a layer of silicone oil on the PET surface to reduce the surface friction coefficient.
Internal Slip Additive: Add a slip agent (such as silica, silicone or wax) during the production process to make it evenly distributed in the PET substrate.
The product thickness usually ranges from 0.18mm to 1.7mm and is suitable for industrial applications that require high transparency, temperature resistance and anti-blocking properties.

Features of Anti-block PET Sheet
Excellent anti-blocking performance: effectively prevent PET sheets from sticking when stacking or winding.
High transparency (for external silicone oil coating): The silicone oil coating is extremely thin and has almost no effect on optical properties.
Good slipperiness (internal type): Low friction coefficient, easy processing and separation.
Temperature resistance: PET substrate can withstand -40°C to 150°C (higher in the short term).
Chemical stability: Resistant to oil, grease, weak acid and weak alkali, suitable for a variety of industrial environments.
High mechanical strength: Anti-stretching and anti-puncture, suitable for die-cutting, stamping and other processing methods.

Advantages of Anti-block PET Sheet
Comparison item | External silicone oil type | Internal slip type |
Anti-stick effect | Excellent, suitable for high-demand scenarios | Good, may slightly decrease with long-term use |
Transparency | High (very thin coating) | May be slightly lower (depending on additives) |
Permanence | May be weakened by friction or cleaning | More durable (slip agent is evenly distributed) |
Applicable process | Suitable for short-term anti-stick needs | Suitable for long-term storage or high temperature environment |
Cost | Higher (additional coating process required) | Lower (direct production) |
Comprehensive advantages:
✔ Reduce production downtime (avoid material adhesion affecting processing)
✔ Improve automated packaging efficiency (sheets are easy to separate)
✔ Applicable to industries with high cleanliness requirements such as food and medical
