Polypropylene Baler Twine is made by twisting and compounding one or more PP films. The composite twines have strong elasticity and strength, and are now widely used for bundling crops’ straw and pasture. Polypropylene twines are the twines used regularly within the agricultural industry and its associated trades, particularly for use within baling machines. Our twine is not only an efficient product to use within the agricultural industry but also as a cost-effective way to bale waste.
