ASTM test method will help measure thickness of plastic film
The new standard (WK54333, test method for measuring plastic film with a non contact capacitance gauge) will support quality control and production of these films.
Doug Lawrence, ASTM member, said: “This proposed standard will help produce thinner and higher quality films. This is great for the sustainability goals of the industry as manufacturers push to reduce material use and waste.”
Lawrence, president of US-based SolveTech, says that the test method will help in getting precise and accurate measurements on thin films. It will also allow for a reproducible set of data points on film samples that correctly characterises the extrusion process.
