<p>Polyester strapping made from polyester and less than 3 % by weight of a polyolefn additive exhibits improved resistance to longitudinal splitting when the strapping is later placed under tension in packaging reinforcement applications. The polyolefin improves the longitudinal split resistance of the strapping without facilitating unwanted longitudinal stretch of the polyester strapping when under tension. The polyolefin additive may be combined with other conventional additives, or may be used alone in order to minimize costs.</p> |
