摘要:
An easily opened package is provided, formed of a substantially rigid, foldable sheet, such as cardboard, and having an opening on one side of the sheet. A plastic film is sealed about the opening and is stretchable to form a pouch for receiving an item to be stored in the package. To form the package, the plastic film is heated and stretched about the item and the cardboard sheet is folded over and sealed together. Prior to forming the package, a pair of opposing cuts are formed in the edges of the film, the cuts facilitating tearing of the film when it is desired to open the package. To further facilitate opening, indicia can be placed on the edges of the cardboard sheet to indicate the point at which tearing is easiest, or notches can be cut in one side of the sheet.
