Protektive Pak Dissipative Impregnated Corrugated Material meets EN 61340-5-1 and Packaging standard EN 61340-5-3, tested per IEC 61340-2-3 and modified IEC 61340-4-8 (ANSI/ESD STM11.31)
Dissipative Impregnated Corrugated
Product in the Work Area
A common problem in the electronics industry is protecting static sensitive product when it is transported or stored outside an ESD Protected Area (EPA).
In addition, the movement of circuit boards or other assemblies containing electronic components within a facility or shipping from subcontractor sites
creates potential for ESD and physical damage. Protektive Pak’s Dissipative Impregnated Corrugated material offers protection from both.

Why Dissipative Impregnated Corrugated Material is the Best Choice for ESD Control Packaging
| |
IMPREGNATED MATERIAL |
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
1 x 106 to <1 x 109 ohms. The conductive layer is in the 5th layer from the surface measuring < 1 x 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 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. |
Dissipative Impregnated Corrugated Material
- Dissipative buried shielding layer mixed in during paper making process - does not rub or scratch off
- Does not lose its ESD properties
- Longer lasting ESD safe package
Coated Material
- Standard Kraft sheet with ESD properties painted or printed on surface
- ESD material is fragile and prone to scratch and rub off
- Not as long lasting

- Carbon added during the paper making process
- Paper is a 6 layer process
- The top surface layer is static dissipative (measures 1 x 106 < 1 x 109 ohms
- Conductive layer is the 5th layer from the surface (measures < 1 x 104 ohms)
- Abrasion test of its thicker construction has shown no loss in particles at 100 cycles, only 1% loss for 200 cycles and 60% loss for 500 cycles.
Similar tests performed on the coated material have shown a 50% loss in particles in only 10 cycles and a 100% loss in 100 cycles.
When dissipative impregnated corrugated container is enclosed (such as a lid in place), the buried shielding layer provides ESD shielding,
protecting contents from electrostatic charges and discharges.
Protektive Pak Impregnated Corrugated
Material Strength
There are two basic test methods to prove the physical strength of corrugated material
- Mullen Burst Test is the puncture resistance measurement for corrugated material
- ECT Test reveals the stacking strength or crushing resistance of corrugated material
Test Results
The industry standard for this material strength should yield:
- 200 for the Muller Test
- 42 for the ECT Test
Mullen Test (Burst Test)
Coated material: 216.8
Protektive Pak Impregnated Material: 284.4
ECT Test (Edge Crush Test)
Coated material: 41.3
Protektive Pak Impregnated Material: 53.3
Summary
The Protektive Pak material had 29% better stacking strength/crushing resistance and 31% better puncture resistance than the coated material.
Protektive Pak’s Impregnated Corrugated Material is physically stronger!
Protektive Pak’s statements are backed by technical data based on independent tests. Independent Testing available upon request.
Returnable Packaging
In-Plant Handlers
Constructed with double thick sides and double or triple thick ends, Impregnated Corrugated containers are built to withstand the abuse
of transportation and continuous reuse, making them a great choice for returnable packaging.
Potentially the least expensive packaging choice over time. Also, because the shielding layer is built into the corrugated material, the boxes will
maintain a quality appearance much longer than painted or coated product.
After transporting product to another facility, the boxes can be reused to ship more product or collapsed and stored for future use.
REDUCE COSTS

REDUCE WASTE
|
| Returnable packaging is much less expensive in the long term |
Eliminate repeated purchases |
"In some situations, packaging may be designed for reuse [and] may be reused numerous times. Examples of these types of ESD protective packaging are hinged containers, boxes, and other rigid or semi-rigid containers. 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." [ESD Handbook ESD TR20.20 section 5.4.3.3.1 Returnable and Reusable Packaging]
ESD Marking and Traceability
"ESD protective packaging shall be marked with the ESD classification symbol as shown in Figure 1 [ESD Protective symbol]” “Packaging should be marked with information that allows traceability to the packaging manufacturer and to the manufacturer's date/lot code information."
[Packaging standard EN 61340-5-3 Packaging marking clause 7.2.1 and Traceability clause 7.23]
