Abstract
A method of wrapping a tray of produce or other articles requiring ventilation is provided. A ventilated package produced in accordance with the method is also provided. In accordance with the method, a sheet of flexible plastic film is applied to an open ended tray. The sheet includes a perforated portion which is bounded by non-perforated lateral edge portions. The sheet is positioned with respect to the tray such that the perforated portion is located over the open end of the tray while the non-perforated lateral edge portions extend over opposing portions of the rim of the tray and down the side walls thereof. The sheet is stretched in such a manner that the non-perforated lateral edge portions are subject to more severe stretching than the perforated portion of the sheet. The sheet accordingly will not tend to tear despite the presence of perforations.
