High Density Polyethylene Negative Sleeves

For quite a while, I used the HD PolyChron negative storage pages from Light Impressions to store my 35mm negatives. They're made of high density polyethylene, and they're roomy enough to hold sleeved negatives. Unfortunately, it seems that Light Impressions had stopped making that product. In fact, the only HDPE products that they seem to have are print sleeves.

Does anyone know of another source for high density polyethylene negative pages?

Greg,

Take a look at Archival Methods. Specifically:

Thanks, Allen. Those look nice, but I'm looking for a single sheet that will hold an entire roll of 35mm film cut into strips.
