Protektive Pak’s Dissipative Impregnated Corrugated material features a unique characteristic, a buried shielding layer. This provides a better value because unlike dissipative or conductive painted material, the buried shielding layer will not rub/scratch off or lose its ESD properties. This translates into a superior, longer lasting ESD safe package.
Third party testing has been performed on Protektive Pak’s Impregnated Corrugated material demonstrating that the buried shielding layer in our corrugated material provides a better value than dissipative or conductive coated (or painted) material.
- 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 Dissipative Corrugated Material meets the ANSI/ESD S541 recommendation, avoiding rapid discharge when contacting ESD sensitive items –
conductive coated boxes DO NOT!
Protektive Pak Dissipative Impregnated Corrugated Material meets ANSI/ESD S20.20 and Packaging standard ANSI/ESD S541 tested per ANSI/ESD STM11.11 and modified ANSI/ESD STM11.31

Watch our Material Test video:
ElectroStatic Discharge (ESD) is silent, quick and potentially lethal to electronic parts. When electronic parts are not properly handled during manufacturing, assembly, storage, or shipping, damage from ESD can reach into the millions of dollars each year.
For an ESD control container to be effective against ElectroStatic Discharge, it must possess certain electrical characteristics:
- Surface resistance <1 x 1011 ohms per ANSI/ESD STM11.11
- Energy penetration <50 nanoJoules per ANSI/ESD STM11.31
Non-shielding containers might be cheaper, but they are not less costly when it comes to handling ESD sensitive items. Anytime ESD sensitive parts and assemblies are handled, regular containers are not a sound option, even part of the time, as the risk of ESD damage is always lingering. As a result, costs will be incurred, either via ESD damage or as an additional investment in discharge shielding packaging and material handling containers.
The disadvantages of cross-using shielding and non-shielding containers include:
- Increased cost
- Risk from ESD damage
- Handling inconvenience
The cost of a discharge shielding container is far less than the cost associated with damaged parts or extra handling that result with a “less expensive” non-shielding container.
Kaizen or continual improvement programs should often involve the ESD control program. When quality defects occur, many corrective actions will be improvements to the ESD control program to prevent recurrence.
Muda or Waste includes The Seven Wastes: Defects, Overproduction, Transportation, Waiting, Inventory, Motion, and Overprocessing.
We recommend using ProtektivePak In-Plant Handlers as a Kanban system. Just start with the three dimensions of the loaded PCB or other ESD sensitive item and determined the optimal size In-Plant Handler. Go to Tek Search.
We recommend using Protektive Pak impregnated corrugated which has a surface resistance of 1 x 10E6 < 1 x 10E9 ohms and is in the middle of the dissipative range. The ESD Association Packaging standard ANSI/ESD S541 section 7.2.2 includes “Packaging materials that are in intimate contact with devices should be dissipative.”
ProtektivePak In-Plant Handlers reduce ESD and physical defects, and can reduce work-in-process inventory as well as eliminating wasteful non-value added activities. As a Kaban container the In-Plant Handler can replace some or all documents. Instead of planners generating work orders, determine how many In-Plant Handlers to have on the shop floor and when cells are empty they signal the need to manufacture more of a particular item. Knowing the quantity of cells in the In-Plant Handler, one can quickly glance at the number of empty cells and know the count.
Protektive Pak impregnated corrugated has a buried shielding layer. For ESD shielding protection, with the lid in place, the In-Plant Handler can be moved or shipped outside the ESD Protected Area eliminating the need for ESD shielding bags. Per Packaging standard ANSI/ESD S541 section 6.2 Outside an EPA “Transportation of sensitive products outside of an EPA shall require packaging that provides:
- Low charge generation.
- Dissipative or conductive materials for intimate contact.
- A structure that provides electrostatic discharge shielding.”
