Polythene was the first full-length album by the UK rock band Feeder and was released May 18 1997 on the Echo Label, and then re-issued on October 28 in the same year in an Enhanced CD version, featuring their UK top 40 breakthrough single "High" and its video. The original version of the album was deleted soon after and is relatively rare due to this reason.

After sizeable critical success, the album had moderate commercial success and was certified silver by the BPI in 2003 after the success of their breakthrough album Echo Park (The album passed the required 60,000 in 2001, but Echo applied for the award in 2003).

The album saw Feeder take on more of a grunge rock influenced sound, which wasn't seen on their other albums that followed. Many critics at the time called the band the UK's answer to the Smashing Pumpkins.
