The ASTM (formerly known as the American Society for Testing and Materials) issued a new D8136 standard for measuring the average thickness and thickness variability of plastic film. Offering a better test method, the new standard was developed by ASTM International’s committee on plastics.
ASTM International member Rob Lawrence, a mechanical engineer at SolveTech Inc said “The new test method is more accurate, precise and easier to use than existing test methods.” “The standard will help almost the entire chain in the plastic film industry, and will likely improve quality throughout the industry,” added Lawrence.
According to Lawrence, the new standard will be useful for film buyers, polymer producers and film producers.
“It will be most useful for aiding transactions between film producers and film buyers,” he adds. “It will allow them to be on the same page with each other regarding thickness and variability. It will help the buyer find quality suppliers, and help quality suppliers be recognized for their efforts.”
The committee on plastics allowed companies to participate in a full inter-laboratory study for the standard. In addition, the committee also received feedback from the companies who implemented the standard.
