Adhesive Coat Weight Verification Sheet

Inspection template for verifying measured adhesive coat weight against target on a laminating or coating line to control bond performance, process stability, and material usage.

Inspection Details and Line Setup

• Date and time of verification
• Line, machine, or coating station identified
• Product, SKU, or job number identified
• Adhesive lot or batch number recorded
• Substrate roll, web, or material lot recorded
• Target coat weight and tolerance documented
• Measurement method selected

Measurement Equipment and Calibration

• Balance or scale calibration status current
• Measurement device zeroed and functioning properly
• Resolution adequate for specified coat weight tolerance
• Reference standard or check weight verified if applicable
• Environmental conditions acceptable for measurement
• Measurement equipment ID recorded
• Calibration or verification certificate available

Coat Weight Sampling and Results

• Sample location 1 coat weight
• Sample location 2 coat weight
• Sample location 3 coat weight
• Average coat weight within tolerance
• Variation between sample points acceptable
• Measured coat weight trend stable
• Measured values documented in inspection record

Process Controls and Corrective Actions

• Adhesive pump, pressure, or flow setting within approved range
• Coating gap, die setting, or applicator setting verified
• Any out-of-spec result documented as a non-conformance
• Corrective action taken or escalation initiated
• Affected material identified and segregated if required

Review and Sign-Off

• Inspection result reviewed by responsible person
• Production release approved after verification
• Inspector signature
• Supervisor or quality sign-off
