Material Thickness Test
ASTM F2251 Standard Test Method for Thickness Measurement of Flexible Packaging Material
Material thickness testing evaluates the thickness of formed packaging cavities. Typical packaging formats for this test method include thermoformed trays and form-fill-seal packaging systems. It is useful in sealing validations and evaluating performance after an event, such as distribution or shelf life. It may also be used as an in-process or incoming inspection tool.
