ABSTRACT:
An easy open, hermetically sealed, display package made from a single sheet of thermoplastic, gas barrier, heat shrinkable film is provided. The sheet is folded to form one end of the package, the fold being spaced apart from a seal parallel to the fold line with the material between the seal and the fold line being unshrunken and the remainder of the material being shrunk around the product and sealed on all sides. A unshrunken strip of plastic material having a line of weakness is adhered to the unshrunken portion which is also provided with a line of weakness which also corresponds to the line of weakness in the unshrunken strip. The material on both sides of the line of weakness serves as tear tabs.
