polypropylene corners

[ejp6976]

I framed my first piece(Michael Everett's Standing Jerry OG) My question is I went on the advice of in the DIY framing guide and clicked on the link for the 5/8" archival corners and purchased them. Well, everyone swears by mylar, but now I notice that the corners are polypropylene. I know poly is archival as well, but will they hurt my OG over time? Do I need to reframe and repurchase the mylar corners to be truly archival? I have around 8 other Everett OG's I need to frame so I want to get this right!

thanks

They should be just fine. People swear by that stuff.
