Benefits of Protektive Pak Impregnated Corrugated vs. Coated Material

  Impregnated vs. Coated Material
1 CONSISTENT QUALITY
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.
2 STATE-OF-THE-ART TECHNOLOGY
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 stayon. 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 SULFUR CONTENT
Manufactured from 100% recycled paper with consistently low sulfur content.
Manufactured from either recycled or virgin paper or a combination of both. Sulfur content may be low or high which can cause corrosion to leads and circuits.

4 GREATER DURABILITY –
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.

7 BETTER VALUE
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.

Per ESD Handbook TR 20.20 paragraph 5.4.3.3.1 Returnable and Reusable Packaging “In some situations, packaging may be designed for reuse [and] may be reused numerous times. The initial cost of these packages may be relatively expensive. However, if the appropriate collection and recycling system is used, the container may be the least expensive choice over time.”

About Protektive Pak

Protektive Pak is a leading manufacturer of ESD Material Handling and Packaging solutions. We offer a complete line of ESD Packaging products for transporting, storing and shipping of static sensitive assemblies. Our products include Storage Containers, Circuit Board Shippers, Open Bin boxes, Reel Storage Containers, Trays, Foam, Tape, Shielding Bags and much more! We also have custom manufacturing capabilities to your meet your special needs, including Thermoforming requirements. Protektive Pak offers a unique “Impregnated” corrugated material that provides greater durability than “painted” corrugated material. The buried shielding layer protects ESD sensitive items (ESDS) and minimizes sloughing and rub-off contamination. We also offer Plastek Industrial Fluted Plastic, an economical alternative to injection molded products and ideal for use where corrugated and /or paper products cannot be used.
