Abstract
A biaxially-oriented plastic netting for use in wrapping articles includes diamond-shaped apertures formed by strands of the netting located at an acute angle to the longitudinal direction in which the web is tensioned for wrapping articles. Strips or strands of edge material are disposed along each longitudinal edge of the netting, and these strips are stretchable to an elongation for permitting the strands in the longitudinally extending central region of the netting to realign into a taught condition without substantial stretching. The strips or strands of edge material are sufficiently resistant to increasing elongation, after the strands in the longitudinally extending central region have become taut, to transmit tension forces to the strands along the longitudinally-extending edges of the netting, to thereby render the strands adjacent each longitudinal edge taut under the tension forces imparted to the netting when the netting is disposed in wrapping engagement with articles to be wrapped.
