You should not be lifting the vinyl off the backing. Properly done is to squeegee the front of the transfer tape real good, then turn the decal transfer tape down and peel the backing away. It makes a huge difference. If you keep trying to lift the decal off the backing, you will actually lift the wax paper up with the decal, then it will be stuck to your decal. I even write that on my instructions. I never have complaints or problems. Oracal 631 has transfer tape made for it. And it is high tack. https://www.uscutter.com/ORATAPE-HT55-Decorative-Film-Transfer-Tape-for-631-Vinyl
