Thickness Testing
Plastic films are often used to encapsulate, preserve and protect products destined for consumers or industry. The thickness of a film affects the material:
- Tensile strength
- Puncture resistance
- Barrier resistance (WVTR, CO2 and O2)
- Visual appeal (Haze & Opacity)

Producing a film of a thickness less than the specification may result in the material not having optimum functionality within the end user application. A film produced with a higher thickness increases the raw material costs for the producer.
It is therefore essential that thickness be accurately controlled.
Test System:
Thickness measuring instrument, often with a high precision LVDT gauging probe which is linear throughout the measurement range and offers highly sensitive/stable measurement circuitry with temperature monitoring with:
- Measurement probe profile according to test standard and target material thickness
- Constant pressure applied to the sample according to test standard
- Defined measurement speed
- Defined measurement dwell time
User Type
- R & D of new materials
- QC testing of production batches
- Incoming material inspection
Applications – all types of films including:
- Barrier films
- PE films
- Lamination films
- Self-adhesive labels
- HDPE films
- LLDPE films
- Shrink Film
- PP Films
Applicable Standards
- ASTM D6988
- ISO 4593
- BS 2782-6 (Part B)
- ASTM D5199
