Anti-Static Black A4 File Folder with Four-Hole Punch - User Manual

Introduction:

Thank you for purchasing our Anti-Static Black A4 File Folder. Designed with electrostatic discharge (ESD) protection (10^5~10^9 Ω surface resistivity), this folder is ideal for storing and organizing static-sensitive documents in electronics workshops, laboratories, industrial archives, and office environments. The two-hole punch design allows for easy integration into binders or filing systems.

Key Features:

• ESD Protection: Yellow "ESD" label indicates static-safe handling.

• Durable Design: Matte black PP material with reinforced edges.

• Versatile Use: Four-hole punch for binding or standalone filing.

• Multiple Thicknesses: Choose from 25mm, 45mm, or 60mm to suit document volume.

Instructions for Use:

1. Opening & Closing:

• Press the snap closure (if equipped) or gently open the folder from the top edge.

• To close, align the folder edges and press the closure until secure.

2. Document Placement:

• Insert A4 documents directly into the folder's interior pocket.

• For binding, align the two holes on documents with the folder's pre-punched holes and secure with rings or clasps.

3. Labeling (Optional):

• Use the blank area on the front cover or spine to label contents (e.g., project name, date).

• The yellow ESD sticker serves as a visual reminder-do not remove it.

4. Storage & Maintenance:

• Store in a dry, cool area away from direct sunlight or heat sources.

• Wipe the surface with a soft, damp cloth if needed. Avoid abrasive cleaners.

• To maintain ESD properties, keep away from high-static materials (e.g., untreated plastics).

ESD Safety Guidelines:

• Use in static-controlled environments (e.g., EPA zones).

• Ground yourself when handling static-sensitive materials stored in this folder.

• Avoid folding, puncturing, or cutting the folder to preserve ESD performance.

Applications:

• Storing circuit diagrams, PCBA specifications, or assembly manuals in electronics manufacturing.

• Archiving lab reports, calibration records, or quality control documents.

• Organizing technical drawings, ISO documents, or device manuals in industrial settings.

Compliance:

This product is designed to comply with international ESD standards for static-safe document handling.

Note:

For optimal performance, use in environments with controlled humidity (40%-60% RH). If the folder shows signs of wear or damage, replace it to ensure continued ESD protection.
