So I have been using the same tape for a few years without issue, changing it every couple of months as needed. Last change was about a week ago.
Today I had to use some web tac for some hoodies and decided to change the tape after since the buildup was pretty crazy. I have been at it for almost 4 hours now and it's looking like I am going to have to get new rubber. I have tried mineral spirits and press wash and a handful of others things google told me to try for removing pallet tape. The paper is more or less completely off by virtue of dissolving, but the adhesive refuses to come off. The areas where I have been able to kind of scrape/rub away the adhesive are trashed because it is literally rolling up pieces of the rubber...WHAT THE F*CK!? It's like the top layer of the rubber is a separate material and is just flaking off...I can usually just peel the tape off and might have to use a little wipe to get some residue, but never had this issue before.
Any ideas?

ink degrader, but its still a pain in the ass, and a long process.

This will remove the goo. http://www.lowes.com/pd_622047-78-QJLT134___ (http://www.lowes.com/pd_622047-78-QJLT134___)
Spread it on work it with a putty scraper. let it set then scrape it off. will need to hit it several times but the adhesive will come up like a sticky gooey jelly, real messy but it will cut the goo.

tried flashing, tried ink degrader, tried laquer thinner. no go on all fronts. It is literally like the paper adhesive has bound to the rubber. If I take my finger and rub on the adhesive it will eventually kind of ball up and come off, BUT it takes the top layer of rubber with it. Like, the very top of the rubber is slightly dull, and as you rub bright white appears and it is kind of rough. It is hard to describe, but it is definitely part of the rubber...

I had the same problem, go to lowes or home depot and get any of that spray goo remover. spray it on and let it sit, use a putty nice, we had to do it. I had everyone in the company doing it till it was done. A real pain in the ass.

I have a sample of adhesive renover i can give you on monday. It works awesome.

Wow Mimosa, I feel for ya.
When I screw up and wait too long, I use kerosene on two or three layers of paper towels soaking overnight. A smooth putty knife will usually do it. Kero evaporates VERRRRY slowly. That's the key.
I use LOW TAC Transferrite or R-Tape. It is mask for vinyl application. It solved lots of my issues.
Good luck!
<Edit: I mistakenly thought you were Mooseman originally. Mini strokes, I guess :( Still doesn't address why THIS paper change was so drastically different. >

Try spot remover from your spot gun. It gets stuff that mineral spirits and lacquer won't touch.
It's worth a shot. I have used it for some pad print ink that NOTHING would remove. Lots of
other stubborn inks.

yea, sonny nailed it, always pull it when the pallets are heated up. also pull it at a angle..corner to corner.

I change my pallet tape about every other week. Always comes right off.

That's the point. Up to now, it has for Mimosa as well.
"So I have been using the same tape for a few years without issue, changing it every couple of months as needed. Last change was about a week ago."
And while the suggestions for help removing the adhesive are enlightening, the underlying question still remains, "why is this time so damn different"?
We do know that rubber tops make things a little more critical on the regular change thing, but still, only a week?

Sorry, I did not read it all. Dang tapatalk makes it somehow easy to miss the point of the thread. I had one pallet when I got the press that was in bad shape. I tried goof off, screen cleaner, mineral spirits and lots more. I got the best results from acetone. It was still a pain in the butt.

Wanted to update everyone on this. I ended up just putting a few layers of tape over the existing crud and printing what I needed to this last week. It sucked and there were issues with the tape adhering properly over some areas of the crud, but I made it through.
Today I talked to Kevin at River City Graphics about it and he gave me a sample of the stuff you see below. Not sure honestly what it is exactly, but it worked instantly and the pallets are pretty close to completely free of crud now, though there are still some spots that just aren't coming off.
I mentioned in my original post about how the adhesive seemed to have bonded to the top layer of the rubber and the second picture is an extreme closeup of what I was talking about when I would try to rub it off. This area had been cleaned with the Rapid Remover stuff, but the adhesive still would not come off unless I rubbed with my thumb for a while, which led to the top layer rubbing off as you see in the photo. If I rub a random spot that does not have adhesive with my thumb, I can't get the layer to come off like this. It only happens where the adhesive has basically bonded to the rubber. This was happening before I even tried any solvents so it must have been some kind of contamination when I applied the tape originally. The only thing I can think of that I have used in the past on any tough areas is either a clorox wipe or a paper towel with 701, and neither has caused this issue in the past. Has anyone else every seen this? It strikes me as weird...
These pallets were supplied new with my Kruzer from GSG a year and a half ago, and are from Action. (GSG upgraded the size and I didn't realize until months later that they used Action pallets instead of M&R for the upgrade)

Acetone, I love that stuff, and in the spot gun as well for plastisol spots on shirts.

I'd say you have the wrong stuff for pallet tape. we just took off pallet tape that was long overdue for changing as it had a really thick mat of felt on top from months of use. heated it up a bit with the flash cures and it came off easily. We do signs so we just use our application tape. Tru-Stock perform Plus application tape. i could leave it on for a year and it'd still come off without much issue. Mind you we're not a 24/7 shop or anything like that.
-
I'm using the same stuff I've always used without any problems. TransferRite something or other. It is the same one that Alan uses I believe.
I have Rtape in the shop as well, but I didn't like it. It seemed to distort easily when applying my tac, causing air bubbles and wrinkles. Also shredded when removing if I recall.
-
It could be a combination of the heat and the adhesive starting to break down the surface of the pallet rubber. If the pallet tape roll around too long on the roll in heat it tends to get a little tough to get off.
-
Double or triple layer the tape on the pallets, since I have done this I have had zero problems replacing the top layer.

And lets not forget the alluring aroma, lol.
Seriously though, that's some toxic stuff.

Damn and I though we are the only shop that encounters this pesky problem of getting plenty of air bubbles, especially after applying the glue.
I`m still open for suggestions for the hands down best pallet tape. We used NEwman tape which sucks on an auto, extremly hard to remove and then we have TransferRite tape, don`t ask me which one, and that gets lots of air bubbles.
We actually had to decommission two pallets as the Newman Tape was not coming off really. Well it did in some areas but the whole process takes too long, so those two pallets are collecting dust for a while now.
-
I find that pushing out the air bubbles from tapes like the Transfer Rite is not a big deal when done right away before the tape is really set, and of course, before it's sticky with adhesive.
I use a plastic squeegee like used with body filler (and I think even comes with some adhesives)
-
No bubbles here unless glue is applied.

I don't see how glue would cause tape that is stuck down to rise up and bubble in spots. My first guess would be that it isn't really stuck down everywhere yet, and those bubbles are just waiting to appear.
-
Yeah we use "Conform" tape which is mild in tack and comes off easily without heat.
Apply like you would vinyl on a sign, center out with a plastic vinyl squeegee.
Few small bubbles may need a poke to get air out.
I second the fact if it is stuck, or secured well, there shouldn't be any bubbles showing up.

You got me there. It`s layered, the tape I mean, but still it should not go bubble nuts.

I juts checked the Conform tape, there are different types, there is low, low-medium and high tack. When you say mild tack you mean low? Just asking as I`m really desparate for a tape I can stick right on the pallet and still comes off easily even after printing a few thousand tees on the automatic. You print on an auto or manual press? I never had an issue getting any of or tales of the pallets that are on use on the manual press.

Hey- this says 4050-RLA
Didn't know it came different tacks.
Thanks for making me look closer.
This one works great if not stretched when applying.

There is an interesting read on the R-Tape website as to what is happening to the glue when it gets hot. Here is the link

Anyway, you are using the tape on an automatic or a manual press? That makes a lot of a difference at least in our shop.

Interesting read, when you think about it adhesive , any adhesive, may be a something like unvulcanized rubber. Heat along with an additive or two is the primary element that turns unvulcanized rubber into your car tire...try dissolving your car tire....makes sense
