Sealed Frame Package?

Create a Post
A recent test has shown another useful aspect
of sealed packages in framing. A low seal package,
i.e. one with box sealing tape running from the
glazing to the backing board (polypropylene double-wall board) with a strip of sealing foil
between the tape and the side of the mat, was
exposed to a strongly oxidizing atmosphere for
a short period. The seal held out the oxidizing
gas. This suggests that such a lined tape seal
could help to keep pollution out of a frame under
normal atmospheric conditions. This package also
eliminates any need for sealing of the rabbet in
the frame.

Another good "magic wand" I have found is a narrow strip of suede matboard. Picks up fuzzies quick and clean, and won't scratch your mat. :cool:

Jan, I have dust-sealed thousands of pictures and have never had a problem with warping. *knocks wood*
The dust sealing does not pinch or bind the edge, just "seals" it.
And Ellen, when I first started dust-sealing, I would do the ole pro-trim trick. But once you get the hang of it, laying the tape so that it just lays down covering that outer scant 1/8" edge is extremely fast and easy. If you do it "just so," no trimming is necessary.
It's a beautiful thing.

I agree Framing Goddess, I have sealed every frame job done here for the last ten years without a return or problem. I use filmoplast p90 to create the dust seal and overlap the corners about one inch to seal them as well, sam@theponytale.com
 
Received a bit of email on this topic over the past few weeks. So I emailed a sampling of "Industry Experts" on this issue. I received positives on this technique - it's well recomended. It was also pointed out that many conservators at rather high levels are using this technique for many reasons including it being the easiest way to seal a rabbet. However they may be using mylar or metal foil tapes as opposed to 810.
 
When I started this thread about 7 months ago, I thought there would be a clear answer: yay or nay. How very young and naive I was!

It's a compelling procedure and one I'd like to explore - maybe with metal foil tape - certainly not with masking tape as I've often seen.

As several have pointed out, this would, among other things, eliminate the need to seal the frame rabbet and may offer some protection against atmospheric contamination. Most appealing is the protection against "booger migration" from the frame rabbet into the frame package.

Just to make sure I understand: Is the metal foil tape we're talking about the Lineco gray Frame Sealing Tape or similar?
 
About 2 weeks ago I started to do a "Let the 'I told you so s' begin" (try to type "so" in plural without having it look like sos! Anyway..) I had a couple of portraits to frame with a light colored mat. I tried and tried to get all the "stuff" out, but could not. Finally I gave up and tried the taped package method (following info from a post by, I think, John Ranes that I had saved.) It worked like a charm!

Now, I'm kicking myself. Why, oh why hadn't I tried that before! Like I've said often, "Old habits die hard!" :rolleyes:

We have just recently switched to coroplast as a backing/filler. this seems to cut the grumblies way way down. This stuff is Grrreeeeaaaaattt!!!
 
Thanks Edie.

I knew that was hanging around here somewhere.

This topic was brought up in my recent recert class . It was siad to be a bad Idea but with a major differance to something that apperas here. The main differance:

The glazing and plastic backing boards should limit the effects of the tape, but the sides of the package must be isolated from the adhesive. A layer of plastic/metal laminate material such as Marvelseal 360, or Metallized Polyester can be cut into small rolls to create isolating layers that can be used to face the inside of the tape where it goes around the package.
Per Hugh Phibbs

Most of the methods discussed omitted this very important set and as such made the package vey prone to moisture and all the back effects it can cause.this is not to mention that alot of methods use Masking tape and the like which can alos cause problems.
some of the packages amount to poor encapsulation techniques and as such can be harful.
