When I repaired punctures I always left the backing on the patch
because:-

If I was over enthusiastic with the solution it prevented the tube
sticking to the tyre.

It saved time!

Hi, Park tells you to leave the cellophane on, take a look:
http://www.parktool.com/repair_help/FAQGP2.shtml
See the section that has the heading -
Patching an inner tube using the VP-1 Vulcanizing Patch Kit

I had removed the cellophane the first time I used them and then read
the instructions. What do you think?

Life is Good!

Well, that's because the cellophane on these patches is not split and
pulling it off from the edge will lift the patch. Therefore, that has
little to do with REMA patches, patches known as the best available.

I think I'll continue to use REMA patches and will remove the
cellophane as REMA sees fit to do. If you don't, and must use the
tube after patching, the patch cannot expand freely with the tube
whereby the glue joint will be stressed as the tube expands to fill
the tire volume (that is obviously greater than the tube or the tube
would wrinkle on installation). REMA has been in this business for a
long time and does a good job.

You may have seen previous discussions on how to patch tubes here, in
which it was proposed that if the patch peels off, then the glue was
not sufficiently dry. You can try that, but even after five minutes
of drying a patch can be pulled off easily by pulling the cellophane
from one edge. That is why I recommend patching the punctured tube,
using the spare tube that should be in the back-up kit, putting the
freshly patched tube in the back-up kit and letting it cure.

That's enough for tires right now.

That's right. Best patches out there, bar none. Mind you, you'd be going
some to use that many in the rest of your life! >>

I will go through that many in 2-3 years. Thorn

Could be.
I've had a wrinkle too (quiet at the back), but put it down to inflating
the tube before the patch has completely set, when I've been in a hurry.
When I've removed tubes that have had the cellophane left on it has
always deteriorated and gone brittle to such an extent that there are
only a few crumbs left anyway.

Over here in the middle of the Colonies (where it is dry and our wheat
was imported) I'm on at least my fourth box (in 20 years of cycling)
of 100 and that is only after buying the small patch kits by the dozen
prior to that. I've had tubes that had 25 patches on them. The only
reason I threw them away was that the stem pulled out because it was
weakened from so much pumping. In the American Southwest, things just
aren't right if you don't find every one of your bicycles with a slow
leak every time you want to use it.

Thanks to our imported Russian wheat, we are cursed with the dreaded
devil weed - Goatheads! Our childern learn how to patch tires before
they can ride. We are to goatheads what OPEC is to oil except for the
exporting part and the getting rich part. If you every find yourself
west of the Mississippi, look carefully before you take your bicycle
off the pavement. I have watched farmers walking across their fields
grow from 5' 7" to well over NBA height from the goathead stuck to
their shoes! No foolin'! Tanks on manuevers at Ft. Carson have had
their treads flattened from the goatheads! Small childred have had to
have blood transfusions from walking barefoot through playgrounds (and
their parents have been publically humilated for allowing their
childern to go around barefoot). Why, I've even seen ... Be afraid.
Be very afraid.
