Abstract
The twine comprises-includes a mixture of at least 95 wt. % polypropylene and at most 5 wt. % additives. The twine is characterized by up to 8% vol. smectic phase. The percentage of the smectic phase is characterized using X-Ray Diffractometry (XRD). The additives are selected from, impact modifier, polyethylene, pigment, and UV stabilizer. The twine is characterized by a ratio between a specific work to a relative stiffness, of between 40 to 55 [J*mm/KgF].
