Foil and Film Storage Environment Monitoring Log

Inspection log for monitoring temperature and relative humidity in foil and film storage areas to help prevent curl, blocking, and material degradation and to confirm storage conditions remain within converting limits.

Inspection Details

• Inspection date and time recorded
• Storage area identified
  Record the room, zone, rack, or bay inspected.
• Inspector name or ID recorded
• Inspection frequency met
  Confirm the check was completed according to the site SOP or monitoring schedule.

Temperature Monitoring

• Ambient storage temperature within target range
  Record the current temperature in the storage area.
• Temperature monitoring device present and readable
  Verify the thermometer, data logger, or display is installed, powered, and legible.
• Temperature control equipment operating normally
  Confirm HVAC, dehumidification, or other environmental controls are functioning without alarms or visible malfunction.
• Temperature trend shows no sustained excursion
  Review the recent log or trend data for sustained out-of-range conditions that could affect material quality.

Humidity Monitoring

• Relative humidity within target range
  Record the current relative humidity in the storage area.
• Humidity monitoring device present and readable
  Verify the hygrometer, data logger, or display is installed, powered, and legible.
• Humidity control equipment operating normally
  Confirm humidification, dehumidification, or other environmental controls are functioning without alarms or visible malfunction.
• Humidity trend shows no sustained excursion
  Review the recent log or trend data for sustained out-of-range conditions that could affect material quality.

Material Storage Conditions

• Material is stored off the floor and protected from moisture
  Verify rolls, sheets, or cartons are elevated from the floor and protected from water intrusion, leaks, or condensation.
• Packaging materials show no visible curl, blocking, or edge damage
  Inspect accessible material for visible quality defects associated with poor storage conditions.
• Storage area is clean and free of leaks or condensation
  Check for standing water, roof leaks, pipe leaks, condensation, dust buildup, or other conditions that could affect stored film or foil.

Deficiencies and Corrective Action

• Deficiencies documented
  Record any non-conformance, out-of-range readings, equipment issues, or material concerns observed during the inspection.
• Corrective action assigned
  Describe the action taken or required, including notification, adjustment, quarantine, or follow-up inspection.
• Follow-up required by
  Enter the due date and time for recheck or escalation if conditions were out of range.
