Part 1

What this upload proves

The document supports single-use plastic free packaging identification for supplies where the offeror chooses or is asked to make that representation.

It belongs in the product, supply-chain, and catalog-claim lane.

Part 2

How to prepare it cleanly

Start by naming the proof role, file owner, source system, date pulled or signed, and whether the file is required, conditional, or optional for the selected offer.

Then compare the file against the pricing workbook, SAM record, eOffer narrative, and category/SIN instructions so the package tells one story.

  • Claim is limited to products or packaging that actually qualify.
  • Evidence is retained for verification.
  • Catalog or Advantage visibility claims are not overstated.
Part 3

What to watch before upload

Making a broad packaging claim without product-specific evidence can create compliance risk.

Use filenames that help the reviewer understand the document before opening it. A clear file name with document type, company, SIN or category when relevant, and date is usually better than an internal shorthand.

The upload goal is calm review: current file, clear purpose, no contradictions.
Examples

What this looks like in practice
