Laminate Bond Strength Test Record

Records peel bond strength results for laminated film samples pulled from production and verifies the measured bond strength meets specification to reduce delamination risk during converting and end use.

Inspection Identification

• Production lot or work order identified
  Record the lot number, work order, or batch identifier for the laminated film sample.
• Sample date and time recorded
  Capture when the sample was pulled from production.
• Sample source identified
  Select where the sample originated.
• Sample identification label present and legible
  Verify the sample label matches the production record and is readable.
• Specification or acceptance criteria referenced
  Enter the minimum acceptable peel strength and any special acceptance criteria.
• Test method referenced
  Document the method used for the peel bond strength test.

Sample Condition and Preparation

• Sample condition acceptable before test
  Confirm the sample is intact, not visibly damaged, and suitable for testing.
• Conditioning environment recorded
  Record conditioning temperature, humidity, and duration if required by the method.
• Specimen dimensions recorded
  Enter specimen width or other required dimensions used for the peel test.
• Number of test replicates prepared
  Record the number of peel test replicates prepared for the sample.
• Specimen edges and bond area prepared per method
  Verify the specimen was cut, separated, and prepared according to the approved method.

Test Setup and Apparatus

• Test machine or force gauge identified
  Record the instrument ID used for the peel test.
• Instrument calibration current
  Confirm the test instrument calibration is current and traceable.
• Crosshead speed or pull rate recorded
  Enter the pull rate used for the peel test.
• Grip or fixture setup matches method
  Verify the grips, fixtures, and alignment match the approved test method.
• Test environment recorded
  Record ambient temperature and humidity during testing if required.

Peel Strength Results

• Replicate 1 peel strength
  Enter the measured peel strength for the first replicate.
• Replicate 2 peel strength
  Enter the measured peel strength for the second replicate.
• Replicate 3 peel strength
  Enter the measured peel strength for the third replicate.
• Average peel strength
  Record the calculated average peel strength across all replicates.
• Failure mode observed
  Select the dominant failure mode observed during peel testing.

Compliance Review and Disposition

• Results meet specification
  Confirm the measured peel strength meets the minimum acceptance criteria.
• Delamination risk acceptable for converting and end use
  Assess whether the laminate is suitable for downstream converting and intended end use.
• Non-conformance documented if out of spec
  If any result is below spec, confirm a non-conformance or deviation record was opened.
• Inspector signature
  Inspector or lab technician sign-off.
