Anti Static PET Film

Films Protection Company manufactures anti static PET film from clear PET/BOPET polyester film with a controlled anti static coating for polyester film applications. It is made for electronic and optical handling where static charge, dust attraction, sheet flatness, and clean converting can affect parts. This anti static clear film is used for display module handling, die-cut PET spacer parts, optical component interleaving, and temporary protection of sensitive surfaces. Surface resistance, static decay, haze, clarity, coated side, and slitting cleanliness can be checked by sample testing.

Product Overview

Anti static PET film is a functional polyester film for clean, flat, and stable handling during electronic or optical processing. The PET/BOPET base gives better stiffness, sheet flatness, tensile performance, and dimensional stability during slitting, stacking, and precision die-cutting. Compared with soft PE-based films, the coated PET film is less likely to wrinkle, stretch, or cling during PET spacer conversion and optical interleaf use.

If a project only says PET polyester film but the defect is caused by dust attraction or static charge, review when PET film and polyester film wording is not enough before choosing between normal clear PET and anti-static PET.

The film can be supplied with one-side or two-side anti static treatment. The coated side is selected according to the contact surface, such as the component, tool, sheet stack, inspection layer, or handling fixture. In a typical factory sample check, the working side can be tested for surface resistance and static decay. Haze, clarity, coating uniformity, roll edge cleanliness, sheet flatness, and slitting dust condition are also observed before mass conversion. A typical clear grade may show haze <=3.0% and light transmittance >=88%, with final values confirmed by grade, humidity condition, coated side, and test method.

Benefits

• Helps reduce static charge during unwinding, slitting, stacking, and part separation.
• Supports clean die-cutting for PET spacer parts, process sheets, and handling layers.
• Gives better flatness and dimensional control than soft film materials used for general packaging.
• Clear appearance allows easier visual inspection of optical and electronic surfaces.
• One-side or two-side coating can match different component contact designs.
• Surface resistance, roll edge cleanliness, and slitting dust condition can be checked before mass conversion.

When Should Surface Resistance and Static Decay Be Checked Before Using Anti Static PET Film?

Surface resistance and static decay should be checked before the PET roll is slit, sheeted, stacked, or die-cut for electronic and optical handling. Readings may change with humidity, test voltage, coated side contact, storage condition, and measurement method. For display modules, optical interleaf sheets, and PET spacer parts, testing should be made on the surface that touches the component. A small batch trial can show dust attraction, static cling, sheet sticking, or difficult part separation after cutting and stacking.

Applications

• Display module handling during clean assembly
• Die-cut PET spacer parts for electronic processing
• Optical part interleaf sheets for surface separation
• Electronic component temporary surface protection
• Cleanroom slitting and sheet conversion
• Clean handling surface protection using anti static PET protective film

How Can Clean Die-Cutting Performance Be Confirmed on Anti Static PET Film?

Clean die-cutting performance should be confirmed through sample cutting before production use. Practical checks include PET thickness consistency, sheet flatness, coating uniformity, roll edge condition, and particle generation after cutting. Because PET/BOPET film is stiffer than softer film materials, it can keep a cleaner shape for spacer parts and optical separation layers. During sample die-cutting observation, check edge dust, burrs, static cling, part lifting, small-piece separation, particle transfer, and edge cleanliness after stacking.

FAQ

How is anti static PET film different from anti static PE film?

Anti static PET film uses polyester film as the base material, so it is clearer, stiffer, flatter, and more dimensionally stable. It is used for electronic die-cutting, optical interleaving, display module handling, and clean surface protection.

Is this film suitable for die-cut PET spacer parts?

Yes. PET film provides stable thickness, clean shape holding, and better flatness during precision converting. Sample die-cutting can confirm edge dust, burr condition, static cling, and part separation.

Can anti static PET film be used for optical components?

Yes. Clear anti static PET film can be used as an optical part interleaf, handling sheet, or temporary protection layer when haze, light transmittance, surface cleanliness, coated side, and sheet flatness are confirmed.

How should surface resistance be confirmed?

Surface resistance should be tested on the required coated side under controlled temperature and humidity. The target range should match the ESD control requirement, contact surface, and handling process.
