Plant Consistency

Keeping Packaging Consistent Across Multiple Plants

Multi-site programs drift in spec/appearance; retailers expect identical packs regardless of plant.

Direct answer

Multi-site programs stay consistent through controlled, shared packaging specifications, aligned supplier qualification, and documentation so every plant runs the same material to the same spec; without spec control, plant-to-plant variation shows up as appearance and runnability differences.

Use one controlled working copy

This work often starts during multi-site rollout; plant variation complaint. Name the program, affected SKUs, current document revision, owner, and decision date so different teams do not build from different versions.

  • Record spec control and mark it confirmed, assumed, or still open.
  • Record multi-site and mark it confirmed, assumed, or still open.
  • Record plant-to-plant consistency and mark it confirmed, assumed, or still open.
  • Record documentation and mark it confirmed, assumed, or still open.
  • Record qualification and mark it confirmed, assumed, or still open.

Commercial handoff

Keep annual usage, ordinary order or release quantity, destination, timing, current supplier commitments, ownership, and one-time charges separate from technical requirements. That makes the next RFQ or review easier to audit.

  • Attach the current package, specification, artwork, quote, or order history when available.
  • Name the person who can approve the next step.
  • Write down exclusions and temporary conditions.

Close the loop

Turn every open item into an owner and due date. Preserve the final decision with the evidence used, rather than leaving it in an email thread or meeting memory.
