Having struggled to get PLA to stick for a few days I tried standard white masking tape.

Works great in an unheated bed. I use the widest I can find. Lasts about half dozen prints and easy to refresh.

Interesting, you might want to put that down on the wiki page: [reprap.org] also a link to the specific one you used would be helpful since there can be such large discrepencies between different brands.
