Self Sealing Esd Ziplock Bags Self Sealing Esd Ziplock Bags

Moisture-proof bags, also known as aluminum foil bags and metallized bags, are laminated by multiple layers of aluminized polyester and polyethylene, which sometimes provide moisture-proof, corrosion and shielding protection for sensitive components. Bags are heat sealable and suitable for vacuum packaging. Most of them contain polyester (PET) to prevent punctures. The metal layer provides electrostatic discharge (ESD) shielding. Bags are primarily used to package ESD sensitive devices before placing them on a circuit board.
