The polyester is polyethylene terephthalate (PET) or polybutylene terephthalate (PBT), both from waste. The base layer is a flat primary layer, preferably a textile and preferably consists of plastic, a polyolefin and/or a polyester of terephthalic acid, preferably a polyester of terephthalic acid from waste.
