1. Specification approval
Application, structure direction, dimensions, thickness direction, features, artwork and acceptance criteria.
Quality planning
Define the checks before production.
A useful quality plan connects the approved specification to the risks that matter: print, dimensions, lamination, seals, closures, filled-pack handling and machine runnability.
Review checkpoints
Project checkpoints
Quality control is a sequence, not a final glance.
2. Incoming materials
Material identity, visible condition and supplier documents against the agreed project plan.
3. Printing
Artwork version, registration, color reference, text, barcode direction and visible defects.
4. Lamination and curing
Appearance, bonding direction, curing record and project-relevant odor or performance checks.
5. Pouch or roll conversion
Dimensions, seals, gussets, zipper, handle, roll winding, core and unwind direction.
6. Final release
Agreed functional checks, appearance, quantity, labeling, packing and retained reference.
Test methods and acceptance limits are project-specific. OTR, WVTR, seal, drop, leak, migration or machine trials should only be promised when they are included in the approved specification.
