Where can I get decent Polythene Jointing Tape for DPM?

[zappastix]

Hi

I will have to join 1200 gauge DPM because I cannot find sheets wider than 4 metres.

I have looked around for Polythene Jointing Tape - not very good reports, especially from Screwfix.

What is the recommended width for Polythene Jointing Tape and how do you go about joining?

Do you overlap by a few inches, or edge to edge covered by tape?

Do you know where I can get a half decent Polythene Jointing Tape for DPM sheets?

Thanks.
