BB450 Clean Clear MBB | Transparent Level 100 Moisture Barrier Bag

The BB450 Clean Clear MBB is a premium, high-strength moisture barrier solution specifically engineered for the most demanding cleanroom environments. Unlike standard metalized bags, the BB450 offers a transparent design, allowing for easy content identification without sacrificing the critical moisture and oxygen protection required for sensitive electronic components and medical devices.

Processed to Cleanroom Level 100 and FDA approved, this bag is the industry standard for applications where cleanliness and visibility are non-negotiable.

Key Performance Features

Superior Strength & Impact Resistance: Designed for critical vacuum applications, the BB450 provides exceptional puncture resistance and durability.
Zero-Stretch Construction: The specific orientation of layers during the lamination process ensures the bag maintains its shape and integrity under stress.
Optically Clear: High-clarity film allows for seamless barcode scanning and visual inspection of contents without opening the protective barrier.
Fully Customizable: Available in multiple formats including 2-seal pouches, 3-seal pouches, side gussets, stand-up pouches, and continuous tubing.

Versatile Integration

The BB450 can be outfitted with several functional features to streamline your workflow:

Recloseable zippers for repeated access.
Tear notches for easy, tool-free opening.
Hang holes (Round or Sombrero) for retail or organized storage display.

Custom Quotes & Volume Pricing

Because the BB450 Clean Clear MBB is available in such a wide variety of custom sizes and configurations, it is offered exclusively via Request for Quote (RFQ). This ensures you receive a solution tailored exactly to your dimensions and the most competitive volume-based pricing.

Material Performance Overview

The BB450 series is a high-performance, non-metalized laminate designed to bridge the gap between standard poly bags and opaque foil moisture barriers. By utilizing a specialized co-extruded structure, this film provides an exceptional barrier against water vapor and oxygen while remaining entirely transparent.

High-Integrity Barrier Protection

Moisture & Oxygen Defense: With an MVTR of .224 gms and an OTR of 2.7 cc, the BB450 significantly slows the migration of contaminants, protecting moisture-sensitive devices (MSDs) from oxidation and “popcorning” during reflow.
Vacuum Retention: The “zero-stretch” 5-mil construction is specifically engineered for vacuum packaging applications. Unlike standard polyethylene, this material maintains its shape under high vacuum pressure, ensuring a tight, long-lasting hermetic seal.

Engineered for Cleanroom Purity

Level 100 Certified: Every batch is processed and packaged to meet IEST-STD-CC1246D Level 100 standards, ensuring it is safe for use in semiconductor, medical device, and aerospace cleanrooms.
Optical Clarity: The non-metalized design allows for 100% visual inspection of contents and seamless barcode scanning through the film, eliminating the need to open the bag and risk environmental exposure.

Mechanical Strength

Superior Puncture Resistance: With a tensile strength of 46,000–48,000 psi, this bag is robust enough to handle heavy or sharp-edged components that would typically puncture standard 2-mil or 4-mil cleanroom bags.
Tear Resistance: High tear-initiation values (60 x 10³ psi) ensure that once a seal is made, the package remains intact throughout the rigors of shipping and handling.

Recommended Use Case:

The BB450 is the ideal choice for Medical Device Packaging and Sub-assembly storage where visual verification is required but moisture sensitivity is a critical concern. If your application requires a Faraday Cage for ESD protection in addition to moisture barriers, we recommend looking at the 3710 Clean A/S MBB.

The Right Bag for the Job: Selection Guide

Choosing the correct cleanroom packaging depends on three main factors: Contamination Sensitivity, Physical Durability, and Electrostatic/Atmospheric Protection. Use the guide below to find the ideal material for your application.

1. 7000 Clean Poly – The Industry Standard

Best For: General cleanroom hardware, medical devices, and pharmaceutical sampling.

Why choose it? A “barefoot” resin with zero slip agents or additives that could leach onto your parts.
Key Benefit: High clarity for easy inspection and ultra-low outgassing.

2. 7200 Clean Nylon – For Rugged Protection

Best For: Sharp-edged parts, aerospace fasteners, and heavy machined hardware.

Why choose it? Significantly stronger than polyethylene with extreme puncture resistance.
Key Benefit: Meets strict NASA and aerospace specifications (Level 100) for high-integrity protection.

3. BB450 Clean Clear MBB – For Moisture & Oxygen Control

Best For: Long-term storage and nitrogen-purged applications where visibility is still required.

Why choose it? It provides a chemical barrier against water vapor and oxygen transmission.
Key Benefit: Prevents corrosion and oxidation without the need for an opaque foil layer.

4. 3710 Clean A/S MBB – Total Environmental Protection

Best For: Highly sensitive ESD components that are also susceptible to moisture (MSL items).

Why choose it? This is our most protective bag, combining a moisture barrier with anti-static properties.
Key Benefit: Creates a “safe-room” for your components, shielding them from humidity and static discharge.

5. 8100 Clean Shielding – The “Faraday Cage” Barrier

Best For: Integrated circuits, PCB boards, and components sensitive to external static fields.

Why choose it? Constructed with a buried metal layer to provide a “Faraday Cage” effect.
Key Benefit: Protects the contents from both direct contact discharge and nearby electrostatic fields.
