Superior Environmental Defense for Sensitive Electronics
When moisture-sensitive devices (MSDs) require maximum protection, the 3600 MBB delivers. Engineered with a robust 6.1-mil multi-layer construction (Dissipative Nylon, Aluminum Foil, and Static Dissipative Polyethylene), this bag provides a superior vapor barrier and EMI/RFI shielding for the most demanding environments.
-
Exceptional Moisture Barrier: Maintains an MVTR of < 0.0003 mgs/100 sq. in./24 hrs.
-
Heavy-Duty Durability: 6.1-mil thickness ensures elite puncture resistance (> 21 lbs) for sharp-edged components or heavy assemblies.
-
Clean & Compatible: Amine-free, amide-free, and polycarbonate compatible; safe for use with aluminum, copper, and silver.
-
Standards Compliant: Meets or exceeds EMI/RFI/Static Shielding requirements and is fully RoHS and REACH compliant.
-
Ordering Information: Packaged and sold in boxes of 1,000 bags for high-volume efficiency.

Compliance & Standards
Series Comparison: 3600 vs. 3710
While both series provide industry-leading moisture and static protection, they are engineered for different physical demands. The 3600 Series is a high-performance barrier balanced for versatility, while the 3710 Series is built for extreme structural integrity.
Quick Specifications Comparison
Which Bag is Right for Your Application?
-
Superior Vapor Blocking is Critical: The 3600 offers an incredibly low MVTR (< 0.0003), making it the preferred choice for long-term storage of hyper-sensitive MSDs.
-
Puncture Resistance: With a rating of > 21 lbs, it excels at resisting “poke-through” from sharp component leads.
-
Flexibility: The 6.1-mil construction allows for easier handling and molding around smaller components while maintaining a robust barrier.
Upgrade to the 3710 MBB if:
-
Maximum Tensile Strength: With 40 lbs/in tensile strength, this bag is designed to hold heavy metal assemblies without stretching or tearing.
-
Extreme Environments: The 7.0-mil gauge provides the ultimate physical “armor” for components undergoing rigorous international shipping or rough handling.
-
Vacuum Integrity: The thicker material is less likely to suffer from “draw-down” failures when vacuum-sealed over irregular or bulky shapes.
Summary Guide
Still Unsure? Use the 3600 MBB for standard high-sensitivity electronics and sharp leads. Switch to the 3710 MBB for heavy-weight payloads or when maximum material thickness is your top priority.
