Moisture Barrier Foil Bag 15 in. x 9 in. Pack of 150 Bags

Heavy-Duty Foil Moisture Barrier Bag – 15 in. x 9 in., Multi-Layer MylarFoil Laminate, Open-Top Heat Sealable, Electrostatic Discharge (ESD) & Vapor Shield, Cleanroom Compatible 

This premium, laboratory-grade 15 in. x 9 in. moisture barrier foil bag is precision-engineered to provide maximum environmental isolation, vapor protection, and electrostatic discharge (ESD) shielding for highly sensitive biological samples, diagnostic reagents, fine powders, and surface-mount electronic components. Fabricated from a high-performance multi-layer laminate matrix (typically integrating dissipative polyester, pure aluminum foil foil shielding, structural reinforcement nylon, and static-dissipative polyethylene), this 3.6 to 6 mil thick open-top bag delivers an exceptionally low Moisture Vapor Transmission Rate (MVTR) and Oxygen Transmission Rate (OTR). Designed to be permanently closed using commercial thermal impulse or constant-heat bar sealers, this puncture-resistant pouch creates an impenetrable barrier against humidity, ambient oxygen, salt spray, light degradation, and cross-batch contamination during long-term storage or high-stakes transport.

Technical Performance and Material Layering

• Ultra-Low MVTR Aluminum Shield: Features a solid inner layer of high-purity aluminum foil that provides an uncompromising barrier against humidity and gas tracking. This layout yields a Moisture Vapor Transmission Rate (<0.0003 grams/100 sq. in./24 hours) that is up to 80 times more effective than standard thick polyethylene plastic alternatives.

• Comprehensive ESD Discharge Shielding: The exterior and interior polymer surfaces are treated with a permanent static-dissipative matrix (surface resistance of 1 x 10^4 to < 1 x 10^11 ohms). This configuration provides safe Faraday cage shielding (<10 nJ energy penetration) to defend static-sensitive electronic controllers or cleanroom sensors from static shocks.

• Puncture-Resistant Nylon Layering: Incorporates a high-tensile structural nylon layer sandwiched into the laminate core. This reinforcement delivers superior puncture resistance (typically up to 16 lbs / 71 N force limits) and high tear thresholds, preventing sharp multiwell plate corners or tooling pins from piercing the pouch.

• Amine-Free Cleanroom Purity Matrix: Manufactured under strict cleanroom conditions to be completely free of volatile amines, silicones, and heavy metals. This ensures the internal contact lining will not outgas or chemically react with sensitive analytical reagents, fine powders, or bare circuit boards.

Key Benefits and Applications

• Reagent and ELISA Plate Archiving: The premier storage choice for enclosing sensitive multiwell assay blocks, dry chromatography sorbents, and unsealed ELISA plates, blocking room humidity from degrading active target surfaces.

• Fine Powder and Granule Containment: Completely opaque, non-transparent foil design eliminates light degradation hazards, making it the standard baseline selection for packaging fine chemical reagents, compound libraries, and light-sensitive pharmaceuticals.

• Vacuum and Inert Gas Packaging: Tough structural wall pliability allows these pouches to be deployed directly inside automated vacuum chambers or flushed with dry Nitrogen gas before sealing, locking down a permanent moisture-free headspace matrix.

• Electronics Storage Protection: The industry-standard dry-pack container for protecting printed circuit boards, surface-mount microchips, and high-precision laboratory automation sensors from corrosion during transit through high-humidity shipping fields.
