Hi Bud250r. Thank you for your response. Do you happen to know if all Acetate Sheeting is PVC and Acid Free? Also, I am not exactly sure how thick (mils) the Acetate Sheeting would need to be? I think it takes 10 mils to equal .01 inches of thickness. I figure the DANSCO Album Page Plastic Sleeve inserts are somewhere between 20 mils to 30 mils thickness.
