A product bundle plastic film shrink wrapper and method of forming same is described. The shrink wrapper comprises a plastic film having shrink properties and formed from a blend having from about 5% to 10% polybutene-1. The plastic film forms a wrapper for the bundle by being shrunk wrapped about the bundle with a lap seal formed by overlapped film end portions of the film in a section of the wrapper. The polybutene-1 provides for the lap seal to have a shear force sufficient to hold the product bundle together and low peel force to permit separation of the overlapped film portion by sliding fingers of a user's hand in an unsealed gap of the lap seal and sliding the fingers along the lap seal whereby to easily remove the wrapper from the product bundle.
