Description
ZXCOOL offers high-performance customized moisture barrier aluminum foil bags designed to provide comprehensive protection for sensitive electronic components during storage, handling, and long-distance transportation. Engineered with a four-layer laminated structure, these bags deliver superior defense against moisture, electrostatic discharge (ESD), electromagnetic interference (EMI), oxygen, and light penetration.
Each bag is constructed using PET/AL/NY/PE (Polyester/Aluminum/Nylon/Polyethylene) or PET/AL/PE composite materials, creating a robust Faraday cage effect that effectively shields contents from static and electromagnetic fields. The aluminum foil layer provides an exceptional moisture vapor barrier, with a Water Vapor Transmission Rate (WVTR) of ≤0.0006 g/100in²/24hrs, ensuring your valuable components remain dry and corrosion-free throughout their lifecycle.

David –
We procure moisture barrier aluminum foil bags for our semiconductor exports, and ZXCOOL’s product has been a game-changer. The four-layer construction (PET/AL/NY/PE) delivers outstanding WVTR performance – we measured below 0.0006 g/100in²/24hrs, which keeps our ICs perfectly dry even after weeks in sea containers with high humidity. The ESD shielding property is a bonus, eliminating the need for separate anti-static packaging. Heat-sealing is consistent, and the material is puncture-resistant, so we’ve had zero damage claims since switching. Third-party RoHS and halogen reports were provided upfront, saving us time on compliance checks. Custom sizing and logo printing were handled smoothly. This bag is now our standard for all moisture-sensitive components.
