Aluminum foil is attached to the outer layer of the laminate film. This is a metal out that is frequently requested by end users. • Light transmittance is 40%, and the contents of the bag can be seen. • The bag is completely shielded from static electricity without generating triboelectricity. • The bag does not have static electricity even if the contents move in the bag. • The bag is completely diffusible from static electricity, so it does not lose its properties regardless of humidity, unlike local treatment. • The special manufacturing method reduces creases and scratches, creating an environment that shields from static electricity. • The weld seal is about 9.5 mm wide, so the inner sealing layer is high performance. Higher quality and durability thanks to a stronger seal than the 3.2 mm wide seal of previous products. • Electrostatic protection symbol and lot number meet ANSI/ESD S541 requirements, helping to improve quality control tracking and identify as ESD packaging. • Lot number engraving provides traceability for quality control. • Poly-carbon compatible, bag free of aminic acid or N-octanoic acid. Corrosion resistance prevents contamination of parts • Tested according to industrial standards, meets or exceeds one or more of the following standards. Electrical and physical requirements of ANSI/ESD S20.20, EIA 541, EIA 625, MIL-STD-1686, and EIA 583
