4 Reasons why you should be using Protektive Pak - MaterialFollow article
Last week we talked about what to look out for when using containers to transport or store ESD sensitive items. Have you implemented our 3 tips yet? Today we thought we'd cover a topic that ties in nicely with last week's post: Protektive Pak® Impregnated Corrugated Material. Never heard of it? Don't panic - we're here to help! Protektive Pak® Material is made from static dissipative impregnated corrugated material with a buried shielding layer - it provides static shielding to protect ESD sensitive items from ElectroStatic charges, and ElectroStatic Discharges [ESD].
Introduction to Protektive Pak® Material
So now you're probably wondering what's different about this type of material - loads of companies out there offer similar products, right? That's true - BUT what makes Protektive Pak® Material so unique is that its ESD properties are manufactured into the liners of the material itself. Many other materials have a coating or paint applied that gives them their ESD properties. This in itself is not a problem. However, it becomes an issue if the outer layer of your ESD container is damaged.

Have you ever removed tape from your ESD container or accidently pierced the surface with a sharp object? If you have, chances are you've found the black coat give way to a lighter brown material. That's your ESD properties gone potentially damaging your ESD sensitive devices inside the ESD container. This will not happen with Protektive Pak® Material - even if the outer layer is damaged, your ESD sensitive items are still protected. Not convinced? Check-out this video:

Independent ESD tests have proven that Protektive Pak® Impregnated Corrugated Material is superior! Click here to see the full test report.
The bottom line is:
- Protektive Pak® impregnated corrugated material has a buried shielding layer.
- Protektive Pak® impregnated corrugated material equals or exceeds the discharge shielding capabilities of a coated box.
- Protektive Pak® impregnated corrugated material has discharge shielding capabilities equal to a metal-out shielding bag.
- Protektive Pak® impregnated corrugated material meets the ANSI/ESD S541 recommendation, avoiding rapid discharge when contacting ESD sensitive items - coated boxes DO NOT.
Comparing Impregnated Corrugated Protektive Pak® and Coated Materials
Now that we have talked about the advantages of Protektive Pak® Material - how exactly does it compare to the more common coated materials out there on the market? The below table provides a summary:
|Impregnated vs. Coated Material|
Manufactured by one paper mill with computerized control, resulting in consistent high quality.
|Manufactured without computer controls and applied at various geographical locations, resulting in quality variations.|
Carbon is added during the paper making process. The paper is a 6-layer process. The top surface layer is static dissipative, measuring 107 to 109 ohms. The conductive layer is in the 5th layer from the surface measuring <104 ohms.
|Material is coated or printed with carbon loaded black ink which is then coated with a clear sealer to help coating stay on. Shielding layer is very close to surface and high carbon content can bleed through. Result is very poor and inconsistent static dissipative effectiveness.|
|3||LOWER SULPHUR CONTENT
Manufactured from 100% recycled paper with consistently low sulphur content.
|Manufactured from either recycled or virgin paper or a combination of both. sulphur content may be low or high which can cause corrosion to leads and circuits.|
1,000 Times Thicker: Abrasion tests have shown no loss in particles at 100 cycles, only 1% loss for 200 cycles and 60% loss for 500 cycles.
|Tests have shown a 50% loss in particles in only 10 cycles and a 100% loss in 100 cycles.|
|5||SLOWS RAPID DISCHARGE
Burying the conductive layer under a dissipative surface reduces the potential for a rapid discharge when contacted by a charged device.
|A very conductive surface that may pose a charged device model (CDM) ESD danger to components stored in open bin boxes, in-plant handlers, shippers, totes, nesting trays, etc.|
|6||BETTER SHIELDING EFFECTIVENESS
Shielding effectiveness is equal to or greater than coated conductive materials.
|Some coated products shield poorly due to inconsistent application procedures by some manufacturers.|
More durable structure, 1,000 times thicker, which consistently shields your product from ESD, is also safer and better for the environment.
|Simple structure which can lack consistency of ESD shielding, durability and safety.|
