Stupid question about a bath looking for an easy answer

[hp1701]

I've recently had a new bathroom suite fitted with a plastic bath. Took off the blue and black plastic at installation. Now several weeks later have discovered that round the plug hole air bubbles are forming underneath a clear plastic layer of polythene. If this covers the whole bath, it's securely attached most everywhere else. So is it more packing material to be removed, or a problem I need to sort out?
Thanks

Sounds like the protective plastic cover, it should be taken off after installation / tiling etc. Watch out for leakage on the bath waste if the fitter did'nt pull it back a bit.
