Quick answer: Prepare a dry-packing enquiry as a system brief: identify the component requirements, barrier bag, sealing process and specified moisture-control accessories. The responsible engineering team must define the process and acceptance criteria; a bag purchase alone is not a validated dry-packing procedure.
Obtain the component requirements first
Ask the component owner or responsible quality team for the applicable packaging and handling requirements. Record the component reference, intended storage and shipment conditions, and the controlled instructions that apply. Mark unknown requirements for engineering confirmation rather than choosing a process from a supplier photograph.
This checklist helps purchasing collect the inputs for review. It does not prescribe baking, floor life, moisture sensitivity classification, desiccant quantity or humidity acceptance limits. Those decisions need the applicable technical documents and the responsible team’s approval.
Specify the barrier bag separately from ESD properties
Identify the proposed laminate, dimensions, thickness and finished format. Ask for the moisture-barrier evidence and its test conditions. If the component also requires ESD protection, list the necessary electrical properties and supporting evidence as separate requirements.
The EOS/ESD Association discusses packaging properties and handling environments; its ESD guidance should not be used as a moisture-barrier rating. Keep electrical requirements, moisture requirements and physical fit together in the brief without treating them as interchangeable.
Collect accessory and sealing references
Where the approved process calls for desiccant or a humidity indicator, record the specified type, supplier reference and handling instructions. Ask the technical team to approve compatibility and placement. Do not infer that an accessory is available from New Solution simply because it appears in a system diagram or purchasing checklist.
For sealing, document the proposed equipment and process reference and ask who will verify seal acceptance. Collect the bag supplier’s relevant processing information for review. Do not copy temperature, dwell time or pressure settings from an unrelated laminate.
Define the opening and receiving workflow
Explain whether the bag remains sealed until use, who receives it and what happens if the seal or package is damaged. Identify the relevant label fields, such as part, lot and packing references, from the controlled process. Keep traceability requirements explicit in the order.
Ask who is responsible for reviewing indicator observations or packaging damage at receiving. Purchasing should record the approved instruction reference and escalation contact, rather than inventing a pass/fail rule for a moisture-sensitive component.
Make the quotation and evidence comparable
- Component and controlled requirement references.
- Storage, transport and receiving workflow.
- Barrier laminate, usable size, closure and packing arrangement.
- Separate moisture and ESD evidence requirements.
- Approved accessory references, with availability to be confirmed.
- Sealing and inspection process references for engineering review.
- Quantity, destination, sample approval and unresolved conditions.
Ask suppliers to identify exactly what their quotation includes. A bag-only offer should not be compared with a complete accessory package without noting the difference. Approve the selected construction and applicable supporting data before placing an order; validate the final process through the responsible technical team.
Frequently Asked Questions
Does this checklist define a dry-packing procedure?
No. It collects purchasing inputs. The applicable component documents and responsible technical team define the process and limits.
How much desiccant should I order?
Obtain the approved requirement for the complete packing system. Do not select a quantity from the bag dimensions alone.
Can a shielding bag be substituted for a barrier bag?
Only after the required properties and exact construction have been reviewed. A shielding description alone does not establish a moisture-barrier rating.
