<p>[QUOTE="Daggarjon, post: 716551, member: 4230"]from what i have been told, not all Mylar is archival suitable, but all Mylar-D is. In most cases, when a company compares Prolar to Mylar, they pointedly say Mylar-D, not just Mylar. Melinex-516 is another compund often compared to Mylar-D- becuase that translates to being archive capable. It gets tougher when choosing a product, because the public at large and the companies who make products for us to buy dont have a clue to the differences betwen Mylar and Mylar-D. So when i buy flips or sleeves, i look for the Mylar, Prolar or Melinex-516 'logo' or brand - this basicaly assures me the product is a polyester film (unless the seller is flat out lying). It always concerns me when a company does not feel safe enough to imprint their company on the flip/sleeve. It woulnt be too difficult to imprint a small logo or bandname on the very edge so as not to interfere with the viewing of the item within. </p><p><br /></p><p>So when i researched and wrote this thread, i didnt know anything except how PVC was bad. Along the way i learned alot about the different chemical compounds, alot of different brands, and how it really doesnt matter how much we spend on a particular product knowing its the same product as something else that sells for half the price. Knowing the chemical the product is made from is alot more important the blindly trusting the company who manufactures it!</p><p><br /></p><p>I know what i buy is safe, for now.[/QUOTE]</p><p><br /></p>
