Polymer compliance isn’t judged by intent. It’s judged by evidence.

Here’s what customers, auditors, and regulators expect to see.

1. Documented Process Control and Risk Management

You must demonstrate how process risks are identified, assessed, and controlled across molding, extrusion, compounding, or forming operations.

2. Material Traceability and Batch Control

Auditors expect:

• Approved resin and additive records
• Batch and lot identification
• Material movement tracking
• Finished product traceability

Traceability gaps are among the most common audit failures in plastic manufacturing compliance.

3. Change Management and Validation

Changes in raw materials, formulations, tooling, or process parameters must be reviewed, validated, and documented before implementation.

Uncontrolled changes raise immediate red flags.

4. Health, Safety, and Equipment Controls

Auditors review:

• Machine safety measures
• Hazard identification and risk assessments
• Emergency preparedness
• Incident and near-miss records

Missing safety controls are critical nonconformities.

5. Environmental and Waste Management

Plastics operations must demonstrate control over scrap, regrind, emissions, waste handling, and recycling activities.

6. Training and Competency Evidence

Operators, technicians, and quality personnel must be trained for their roles, with records proving competence.

Verbal explanations don’t hold up during audits.

7. Recordkeeping and Data Integrity

Production logs, inspection records, and monitoring data must be complete, accurate, and consistently maintained.

8. Corrective Action and Continuous Improvement

When defects or deviations occur, auditors expect root cause analysis, corrective actions, and verification of effectiveness.

Facilities that learn from issues are always viewed more favorably.
