What Evidence Should Qualify Bottle, Preform and Cap Suppliers?
Approve packaging suppliers against the actual food-contact use, drawings, materials, cleanliness, capability and traceability required by the plant. Confirm samples on the real line and finished pack, then define incoming checks and formal notice before material, mold or process changes. A supplier certificate or low defect sample is only one part of qualification and must not be invented or generalized. Applicable food-contact and product rules, approved specifications and ongoing performance control the decision.
Approve packaging suppliers against the actual food-contact use, drawings, materials, cleanliness, capability and traceability required by the plant. Confirm samples on the real line and finished pack, then define incoming checks and formal notice before material, mold or process changes. Begin with legal supplier identity: document legal supplier identity from current site evidence; name the owner, source and review date. Use food-contact evidence next. Test normal and credible adverse food-contact evidence conditions; state the exception and stop rule. Close the controlled drawing stage through controlled drawing evidence, specifically a controlled drawing interface map with closed gaps or named owners and due dates.
Legal supplier identity
Document legal supplier identity from current site evidence; name the owner, source and review date. Legal supplier identity risk: weak legal supplier identity evidence leaves ownership and the decision basis unclear. Retain a dated legal supplier identity basis with source, owner, status and approval.
Food-contact evidence
Test normal and credible adverse food-contact evidence conditions; state the exception and stop rule. Food-contact evidence risk: incompatible food-contact evidence can block startup or permit an unsafe release. Retain a food-contact evidence test showing conditions, raw result, exception and disposition.
Controlled drawing
Trace controlled drawing across physical and responsibility interfaces; close or assign every dependency. Controlled drawing risk: unmapped controlled drawing leaves an interface outside effective control. Retain a controlled drawing interface map with closed gaps or named owners and due dates.

Working comparison: Material specification · Hygiene and storage control · Lot traceability
At material specification, control the approved material specification basis and reopen it after a relevant process, material or site change. Set hygiene and storage control beside material specification; observe hygiene and storage control at the decision point with a named method and verified instrument status. Lot traceability decides the case. Untested lot traceability can fail when routine conditions vary. The material specification table entry pairs its action with the controlled material specification revision and its requalification trigger; the risk for hygiene and storage control is that poorly located hygiene and storage control can hide deterioration until product is affected.
Material specification
Control the approved material specification basis and reopen it after a relevant process, material or site change. For Material specification, compare the result against the controlled material specification revision and its requalification trigger; reject the option if outdated material specification separates the approved basis from the installed condition.
Hygiene and storage control
Observe hygiene and storage control at the decision point with a named method and verified instrument status. For Hygiene and storage control, compare the result against the hygiene and storage control location rationale, method and instrument status; reject the option if poorly located hygiene and storage control can hide deterioration until product is affected.
Lot traceability
Challenge lot traceability at startup and stable production, then reconcile any difference. For Lot traceability, compare the result against startup and stable lot traceability results with approved exceptions; reject the option if untested lot traceability can fail when routine conditions vary.

Credible loss: Change-notification rule · Capability samples · Line trial
Control starts with change-notification rule, passes through capability samples, then tests line trial. A failure of change-notification rule matters because unclear change-notification rule ownership delays containment, investigation and restart. For capability samples, retain a signed capability samples comparison using common assumptions and stated exclusions. At line trial, contain the line trial event before unrepresentative line trial can pass a convenient trial and fail in routine use.
Change-notification rule
Assign change-notification rule to a named role with an escalation path and dated closure. Change-notification rule risk: Unclear change-notification rule ownership delays containment, investigation and restart. Detection and containment use the change-notification rule owner, escalation route and closure entry.
Capability samples
Compare capability samples options on the same assumptions and state every exclusion. Capability samples risk: Non-comparable capability samples options can make weaker evidence appear acceptable. Detection and containment use a signed capability samples comparison using common assumptions and stated exclusions.
Line trial
Verify line trial with representative inputs, operators and credible operating variation. Line trial risk: Unrepresentative line trial can pass a convenient trial and fail in routine use. Detection and containment use the line trial protocol, actual conditions, raw results and approval.
A supplier certificate or low defect sample is only one part of qualification and must not be invented or generalized. Applicable food-contact and product rules, approved specifications and ongoing performance control the decision. Authorize incoming inspection from the incoming inspection trend, investigation trigger and dated review decision. Revisit nonconformance response whenever disconnected nonconformance response can expose product, people or continuity. Keep periodic performance review open; the periodic performance review project must approve periodic performance review only when gaps are closed or retained as named, dated actions. Close periodic performance review with the accepted periodic performance review record with residual actions, owners and due dates.
Incoming inspection
Trend incoming inspection, define the investigation trigger and record the review decision. Acceptance relies on the incoming inspection trend, investigation trigger and dated review decision. Without incoming inspection trends, drift can outrun investigation. Reopen Incoming inspection when that condition occurs.
Nonconformance response
Connect loss of nonconformance response to product hold, safe state and continuity response. Acceptance relies on a cause-and-effect test linking nonconformance response loss to the intended response. Disconnected nonconformance response can expose product, people or continuity. Reopen Nonconformance response when that condition occurs.
Periodic performance review
Approve periodic performance review only when gaps are closed or retained as named, dated actions. Acceptance relies on the accepted periodic performance review record with residual actions, owners and due dates. Open periodic performance review gaps can be mistaken for final acceptance. Reopen Periodic performance review when that condition occurs.

What must be decided about Legal supplier identity?
Document legal supplier identity from current site evidence; name the owner, source and review date. Keep the point open until its evidence owner and review date are named.
Which record supports Material specification?
The controlled material specification revision and its requalification trigger. A file name alone does not prove the actual conditions, result or disposition.
What failure should trigger review of Capability samples?
Non-comparable capability samples options can make weaker evidence appear acceptable. Contain affected product or people, trace the effects and authorize restart against the approved rule.
Who closes Periodic performance review?
Assign it to a named role. Seek specialist, supplier or authority confirmation where the evidence crosses the project team’s competence boundary.
