7000 Clean Poly: High-Purity Virgin Polyethylene for Critical Environments
The 7000 Clean Poly is a premium, general-use packaging film specifically engineered for the most demanding cleanroom applications. Manufactured from Pure Virgin Barefoot Polyethylene, this film is free from slip agents, antiblock, and antioxidants, ensuring an ultra-pure barrier that will not leach chemicals or contaminants onto your sensitive components.
Processed to IEST-STD-CC1246E Level 100 cleanliness standards, the 7000 Series provides a high-clarity, reliable solution for aerospace, medical device, and semiconductor packaging where material integrity is non-negotiable.
Key Performance Features
-
Barefoot Resin Purity: Contains no additives or processing aids, eliminating the risk of “greasing” or outgassing on high-value parts.
-
Exceptional Clarity: The transparent, high-gloss finish allows for effortless visual inspection and barcode scanning without compromising the cleanroom seal.
-
Strong & Versatile: Despite its high purity, the 7000 Series maintains the rugged durability required for vacuum sealing and industrial handling.
-
Critical Environment Quality: Meets the stringent particulate and non-volatile residue requirements necessary for critical scientific and defense hardware.
Configuration & Ordering
The 7000 Clean Poly is available in a wide variety of stock sizes to support your production workflow.
-
Formats: Available as individual bags, continuous lay-flat tubing, or sheeting.
-
Thickness: Offered in 2 mil and 4 mil gauges for customized puncture resistance.
-
Quantity: Sold in 1,000 bag increments for high-volume efficiency.

Product Specifications
The 7000 Series is a high-clarity, virgin polyethylene film engineered for the most demanding contamination-controlled environments. Unlike standard poly bags, the 7000 series is “barefoot” resin—manufactured without slip agents, antiblocks, or antioxidants—ensuring a leach-free, ultra-pure barrier for sensitive aerospace, medical, and semiconductor components.
Performance Highlights
-
Ultra-Low Outgassing: Ideal for high-vacuum applications and sensitive optical or electronic hardware.
-
Superior Clarity: High-visibility film allows for easy part identification without compromising the protective seal.
-
Structural Integrity: Engineered for high puncture resistance and tensile strength to handle heavy or sharp-edged components safely.

| Seal Strength | ASTM – D882 | 20 – 60 psi |
Quality & Compliance
To ensure the highest level of purity, every 7000 Clean Poly bag is:
-
Extruded and converted in a controlled environment.
-
Cleaned and packaged within an ISO Class 5 (Class 100) cleanroom.
-
Vacuum-sealed in double-poly liners to prevent contamination during transit and storage.
Note: For applications requiring static dissipation, please refer to our 7100 Clean A/S Poly series.
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.
Best For: General cleanroom hardware, medical devices, and pharmaceutical sampling.
Best For: Sharp-edged parts, aerospace fasteners, and heavy machined hardware.
Best For: Long-term storage and nitrogen-purged applications where visibility is still required.
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.
Best For: Integrated circuits, PCB boards, and components sensitive to external static fields.
