Third Party Testing Proves Protektive Pak’s Impregnated Corrugated Material is Superior

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.

 Proven…

  • 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

Do Protektive Pak In-Plant Handlers Need to Have Lids on While ESD Sensitive Items are in Them?

37150CircuitBoard

 Outside the ESD protected area (EPA), the Protektive Pak lids need to be in place to provide the electrostatic discharge shielding ESD control property which is required by the Packaging standard ANSI/ESD S541. Per section 6.2 Outside an EPA “Transportation of sensitive products outside of an EPA shall require packaging that provides: 1. Low charge generation. 2. Dissipative or conductive materials for intimate contact. 3. A structure that provides electrostatic discharge shielding.”

Inside the EPA, it would still be a good idea to have the lid in place, but it is not a requirement. The Protektive Pak impregnated corrugated has a buried shielding layer. In shielding, we utilize the fact that electrostatic charges and discharges take the path of least resistance. The charge will be either positive or negative; otherwise the charge would balance out and be no charge.

Like charges repel and so the electrostatic charge will reside on the outer conductive surface.

Faraday

A Faraday Cage effect can protect ESDS contents in a container with a shielding layer (this is what a shielding bag has). This Faraday Cage effect protects people in real life when a lightning bolt strikes an airplane or automobile with the charge residing on the outer metal fuselage or car body.

The Faraday cage effect causes charges to be conducted around the outside the surface of the conductor. Since like charges repel, charges will rest on the exterior.

To complete the enclosure, make sure to place lids on boxes or containers, and close shielding bags. Packaging with holes, tears, or gaps should not be used as the contents may be able to extend outside the enclosure and lose their shielding as well as mechanical protection.

How to Properly Use An ESD Shielding Bag

A basic principle of ESD control in a manufacturing environment is that ESD susceptible items should only be removed from ESD protective packaging when they are in an ESD protected area (EPA). Most EPAs are made up of “Islands” of control; the packaging / materials handling system must provide proper protection for ESD susceptible items during transport and storage outside those “islands” of control. When moving ESD susceptible items outside an EPA, it is necessary for the product to be packaged in closed ESD Shielding Packaging.

BagUseLabel

Tip# 1 – Not a Worksurface

Do not use a shielding bag as an ESD worksurface. Although a shielding bag is safe to use around ESD susceptible products, it is not intended to be a worksurface for product. It should be set aside or discarded after removing the product from the bag.

BagUseProbe

Tip# 2 – No Potholders or Tacos

BagUseTaco

Do not use a shielding bag as an “ESD potholder” or “ESD taco.” This type of use offers no ESD protection to the product.

Tip# 3 – Enclose Product

BagUseCircuitBoard

Shielding bags should be large enough to enclose the entire product and closed with a label or zipper style bag. 

Tip# 4 – Remove Charges

BaguseMat

Place closed bag on an ESD worksurface before removing product to remove any charge that might have accumulated on the surface of the bag.

Tip# 5 – Don’t Over-Use

BagUseOveruse

Re‐using shielding bags is acceptable so long as there is no damage to the shielding layer. Bags with holes, tears, or excessive wrinkles should be discarded.

What is Returnable Packaging?

ReturnablePackaging.jpg

“Returnable Packaging,” as defined by Returnable Packaging Association (RPA), is packaging which includes “…reusable pallets, racks, bulk containers, hand-held containers and dunnage that move product efficiently and safely throughout the supply chain. Reusable packaging is typically used by manufacturers/processors and their suppliers/customers in a well-organized supply chain, with very tightly managed shipping loops.”

So what does this mean? Returnable packaging is manufactured of durable materials and is specifically designed for multiple trips and extended life.

When a vehicle leaves a facility to drop off product and then returns to pick up more product, you have what is called a “milk run”. Milk runs are perfect for returnable packaging.

Utilizing returnable packaging cuts down on material costs as well as total cost. There is much less need for repeated purchasing of disposable containers.  The money saved will now go towards your profit line! In addition, returnable packaging cuts down on waste by re-using packaging rather than just using it once and throwing it away. No more dumpsters full of unneeded waste!

Protektive Pak In-Plant Handlers are a great choice for reusable packaging. Made to protect ESD sensitive components, the boxes are constructed with double thick sides and double or triple thick ends and are extremely durable. They withstand the abuse of transporting. After transporting product to another facility, the boxes can be reused to ship more product or collapsed and stored for future use.
