Abstract

The present invention relates to a phonograph record (AKA a vinyl record, or vinyl, or an LP) which is biodegradable, compostable and/or comprises a bioplastic. The record has a resin or polymer composition (or a biodegradable plastic) primarily made of polylactic acid (PLA) with some polybutylene adipate terephthalate (PBAT) which is plant based or derived, for example from raw materials. This can replace the PVC used in prior art records, making the record cheaper and easier to manufacture and reducing the environmental impact. The record can meet the EU compostable standard EN13432.

Abstract

The present invention relates to a phonograph record (otherwise known in the art as a vinyl record, or "vinyl", or an LP) which is biodegradable, compostable and/or comprises a bioplastic. The record has a resin or polymer composition made of a biodegradable plastic which is plant based or derived, for example from raw materials. This may comprise sucrose and/or is sugar based. This can replace the PVC used in prior art records, making the energy use less and the cost of producing the record potentially cheaper and reducing the environmental impact. The record can meet the EU compostable standard EN13432.
