Adhesive Changed?

I've been buying this custom tape for a couple years now and I love it - looks great on my parcels and easy to use! My most recent order, however, seems to have a different formulation. The adhesive barely sticks, no matter what amount of water I use, and I keep having to re-stick the tape down. My boxes haven't changed, and the last bit of tape from my previous order works fine. Definitely will have to find a new supplier for this product as the new stuff isn't fit for purpose.
