These are PVC, so they are not archival safe for longterm use?

I'm not sure about that. I do know it's the only way PSA will accept cards. That's why I got them.

Francisco, I use Print File archival preservers and have for many years. I don't know what they are made of but they are a clear plastic. Pictures show through fine and I have never had a photo damaged. I highly recommend.

I read that they are BPA/PVC free but I would double check the company's website to confirm.

The statement was probably written by their lawyers to avoid problems with PVC piping. I use these on PVC in my irrigation system and on hydraulic controls on my tractor with success. I wrap the pipes and the heat tapes with aluminum foil then pipe wrap insulation to disperse the heat and to avoid losing the heat to the environment. I'm not sure I would put up with the risk of shorts and subsequent fire for an in house application. Peter

my guess is not - since it doesn't say so on the package. I know we've left them outside through storms and they hold up very well, but I don't think that's really a test to their degradability.

This is a food-grade PVC. It retains heat better than other materials to assist in drainage (if that's what you need) and it's resistant to chemical sterilization. I won't say that it is safe, but I will say I've been using them for years and I'm still alive. This mold is also carried by JayBee Industries, makers of "The Vat" pasturizer. If Bob trusts it, so do I.

What exactly makes PVC "Eco safe?" Are these mats available in retail outlets?

They really wouldn't be safe in these. You have to use a box or they will warp or break. I purchase records on this site and the ones in boxes sometimes don't even make the trip because they get tossed around in shipping.

We've had them on the shelf for 2 years before using them and they hadn't changed at all. I think you'd be fine to store them.

They are dry, no need to freeze, and keep a very long time. Store them carefully because they are brittle and over time some may crack. They are still useable, but your summer rolls won't come out as pretty

Not likely, unless you load them with bricks or lead ingots, than they may fail. I've never have one fail after 5+ years of all weather use.

I have records with similar sleeves on them that are close to 30 years old. The sticky stuff lasts for resealing just fine, unless dirty. A rare few have torn, usually from being man-handled or trying to fit a fat double album in them. Highly recommended.

I agree with J. Marshall about the material. We use these to send confidential business documents to an offsite storage facility because they are much sturdier than even "better" bankers boxes. Whenever we recall those from storage, the plastic is tearing & breaking. These seem to hold up way better. Hope this helps!

These do not appear to be homemade. I would rate the quality as so-so, will probably last you a few years if they are stored inside.

No, they are not labeled as 'food safe' and, most likely, should not be utilized as such. PVC has been shown to leach pthalates and dioxins (both of which can cause hormonal and developmental issues). With that said, PVC has been used in household plumbing for decades with little consequence, so the decision lies with the end user. I think your best bet would be a polypropylene bulkhead.

I am not sure they are labelled as archival, but I love to store my photos in them. I have not had any problems.
