Subject: Yupo and Denril synthetic papers
I am looking for technical research or aging studies performed on Yupo 100% polypropylene paper and Denril vellum drafting film. I would appreciate finding technical information including knowledge of coatings, additives such as optical brighteners or plasticizers.
