Abstract
A novel thermoplastic baling wire suitable for baling waste destined for either recycling or for refuse derived fuel, having recyclable properties and good self-knotting properties comprises recycled thermoplastic material is polyethylene terephthalate comprising 6%±2% by weight of polyethylene. A method of manufacture of said baling wire comprises preparing a masterbatch of recycled polyethylene terephthalate (rPET) including one or more multi-functional acrylic oligomers to obtain a modified recycled polyethylene terephthalate; combining said modified rPET with a phthalocyanine based nucleating agent; transitioning said modified rPET from molten to solid state; and extruding said modified rPET material into an elongate band.
Claims26
