ESD Anti Static PET Protective Film

Clear Adhesive Film Company is a manufacturer of ESD Anti Static PET Protective Film for circuit board handling, display panel inspection, and static-sensitive component protection. The film uses clear PET backing, an ESD control coating, and low tack adhesive to manage charge build-up during peeling, transfer, temporary masking, and assembly. With controlled surface resistance typically tested at 10^6-10^9 ohm/sq, it supports clean removal, surface visibility, and stable anti-static performance in real production handling.

Product Overview

This film is developed for production surfaces where static charge, dust attraction, adhesive transfer, and inspection visibility must be controlled together. It is not positioned as a broad finished-goods cover. Its role is temporary ESD-controlled protection during circuit board handling, display module checking, component transfer, inspection, and assembly preparation.

The PET backing gives the film strength for slitting, laminating, cutting, and workstation movement. The anti-static treated surface helps release charge generated by peeling, contact, and roll unwinding. In typical factory checks, surface resistance is commonly measured within 10^6-10^9 ohm/sq, but results can vary with coating design, humidity, dwell time, operator handling, and test method. Sample testing on the real production surface is recommended before mass use.

For panel inspection and process checking, the clear PET structure allows operators to see markings, defects, alignment points, and edges while the film remains applied. Standard transparent grades typically show 88%-91% light transmittance and haze below 3.5%. Clear Adhesive Film Company supplies roll stock, slit rolls, and converted formats with stable unwinding, neat roll edges, and narrow roll slitting typically controlled around +/-0.5 mm, depending on width and roll structure.

Benefits

ESD control coating helps reduce static accumulation during peeling, handling, inspection, and assembly.
Controlled surface resistance at 10^6-10^9 ohm/sq supports static dissipative process protection.
Low tack acrylic adhesive, typically 3-25 g/25 mm, holds the film flat without aggressive bonding.
Clear PET backing keeps circuit markings, panel surfaces, defects, and inspection points visible.
Lower dust attraction helps keep particle-sensitive production surfaces cleaner between workstations.
Stable release, clean slitting edges, and +/-0.5 mm narrow-roll tolerance support accurate converting.

Production Line

How does controlled surface resistance help during PCB and display panel handling?

During PCB handling, panel inspection, and component transfer, the film needs to do more than simply cover the surface. Charge can be created when the film is peeled from the roll, laminated onto a surface, touched by operators, or moved between workstations. The static dissipative coating helps release this charge in a controlled way. In sample observation, stable resistance within 10^6-10^9 ohm/sq and lower dust attraction are useful where particles, handling marks, or sudden discharge risks may affect assembly quality.

What makes low tack adhesive important for temporary electronic surface protection?

Low tack adhesive is important when the film is used as a temporary process layer on PCB surfaces, display panels, glass covers, and component areas that require clean handling. It should stay flat during movement, inspection, cutting, and assembly support, but it should not behave like permanent bonding tape. Controlled adhesion, commonly referenced around 3-25 g/25 mm, supports surface holding and clean removal. Dwell time, temperature, pressure, removal speed, and removal angle should still be confirmed with samples.

FAQ

Is this film mainly for scratch protection?

It may help reduce handling marks, but its main value is ESD-controlled surface protection with controlled resistance, lower dust attraction, and clean temporary coverage during electronic processing.

Can the surface resistance be customized?

Yes. The common test range is 10^6-10^9 ohm/sq. Coating design can be adjusted, and final resistance should be confirmed under actual handling conditions.

Will the low tack adhesive leave residue?

It is designed for clean removal after short-term process protection. Residue performance still depends on surface material, dwell time, pressure, temperature, and removal speed.

Can this film be supplied in slit rolls or die-cut formats?

Yes. Clear Adhesive Film Company supplies jumbo rolls, slit rolls, and converted formats for circuit board processing, panel inspection, and static-sensitive component protection.
