Assign the inputs before requesting a trial
Make a list of the bulk product, pouch or film, any sheet, artwork and shipping cartons. Identify which party supplies each input and who approves its specification. Ask which samples or documentation the proposed filling team needs. For buyer-supplied materials, confirm the acceptance checks and what happens if supplied stock does not meet the agreed specification.
Use a filled, sealed sample
Check how the pouch looks, opens and dispenses when it contains the proposed product. Include filled width, height, marking position and visible seal issues in your review. For a sheet mask, inspect the folded placement. Ask both parties to agree on the methods and limits for fill-weight, seal or leakage checks before comparing trial results.
Release artwork against the actual pack
Compare the printed design to the approved pouch drawing and the physical filled sample. Check the location of the cut edge, seal, tear notch and lot marking. If the appearance or placement changes during the trial, agree who updates the file and review a corrected proof. Store the final artwork reference alongside the approved trial sample code.
Separate cost and acceptance decisions
Request a quote with quantities per artwork version and any one-time artwork or setup costs shown separately. Confirm what happens to leftover bulk and packaging, and who records the final packed count. Ask for the milestones that affect completion, including receipt of customer-supplied materials and sign-off of the final sample. Confirm standalone filling scope against the project before committing.
