WHS-B Antistatic Moisture Barrier Bags

WHS-B Antistatic Moisture Barrier Bags are engineered to provide top-tier protection for wafers and sensitive electronics during storage and transport. These multi-layer bags offer advanced defense against moisture, static electricity, and contamination, ensuring product safety in demanding environments.

The multi-layer construction features Anti-static Polyester (12 µm), Aluminum foil (7 µm) for moisture protection, Nylon (15 µm) for puncture resistance, and Polyethylene (115 µm) for strength, with an additional anti-static layer for complete ESD protection. This ensures products are shielded from environmental factors and electrostatic discharge while resisting punctures.

With a low moisture transmission rate, WHS-B bags allow for extended storage without damage. Larger sizes have a block-bottom design to reduce folds and contamination risks.

Compatible with various wafer cassette sizes, they are ideal for cleanroom use with their abrasion-resistant materials.

WHS offers short lead times and small order quantities to meet customer needs. With six standard sizes and customizable options, WHS-B bags provide flexible solutions for high-quality storage and shipping.

Manufactured in an ISO9001 certified facility and CE certified, WHS-B bags meet international standards for quality and safety, offering a cost-effective solution for safeguarding wafers and electronics in the semiconductor and electronics industries.
