ESD Bag Selection When Parts Leave a Protected Area

When an electronics part moves from an ESD protected area to another location, choose its packaging against the complete handling route. A bag already used at a workbench is not automatically approved for the next journey. Write down where the pack is loaded, where it travels and where it will be opened before asking for a substitute.

Separate the required properties

The ESD Association distinguishes low charging, conductive or dissipative properties, and discharge shielding. Its guidance calls for low-charging, conductive or dissipative packaging within an ESD protected area; packaging outside that area also needs discharge shielding. A pink color or an anti-static product name does not establish all those properties. See the ESD Association's packaging guidance and have the person responsible for your ESD program approve the specification.

Keep catalog identity separate from qualification

These two Packrift listings share a stated 3 × 5 inch size but describe different bag formats. The dimensions and order quantities help identify an order. They do not establish an approved substitution between the products.

Listed product details to carry into a qualification request
SKU and product route Listed format Buying unit
STC505 3 × 5 inch, 3 mil, open-end static shielding bag 100 bags per case
PBAS1035 3 × 5 inch, 4 mil, pink flat anti-static poly bag 1,000 bags per case

The descriptions available here do not include the product-specific test documentation needed to qualify either listing for your route. A higher film thickness is not a substitute for that documentation. Neither product is presented here as compliant with your ESD program.

Build a purchase request that can be answered

  1. Name the complete route. For example, record a bench-to-stockroom transfer separately from a shipment to a customer. Identify the actual receiving location; “internal use” is too vague if goods leave the controlled area along the way.
  2. Name the exact candidate. Include STC505 or PBAS1035 and the product link. Ask for documentation tied to that item, rather than accepting a description of an entire bag family.
  3. Identify the approval record. Record who reviews the evidence and where the accepted packaging specification is stored. Purchasing should be able to distinguish an approved item from a candidate still awaiting review.
  4. Separate quantity from suitability. State the required number of bags and the listed case quantity. The 100-bag and 1,000-bag cases are different purchasing units; the smaller order is not evidence of a better technical choice.

Preserve the decision on reorders

Keep the approved SKU, supporting document reference and route description together. If a later request changes the item, destination or packaging, return that change to the responsible reviewer instead of carrying the old approval forward by matching size or color. The anti-static shielding bag guide provides related catalog routes for that review.
