Patent ID: 7083838

Claim:
A combination product and shrink-wrap packaging film having enhanced optical and mechanical properties so that the product can be seen more clearly through the packaging film and the packaging film is not punctured easily when an outside force is applied thereto, the combination comprising: a product; and a shrink-wrap packaging film having a selected overall packaging film gauge thickness and contacting and substantially surrounding the product and shrunk thereon, the packaging film comprising a first outermost layer of elastomer in a range of about 10% to about 25% of the overall packaging film gauge thickness, a second inner layer of polyolefin in a range of about 50% to about 80% of the overall packaging film gauge thickness and overlying and abuttingly contacting the first outermost layer of elastomer, and a third outermost layer of elastomer in a range of about 10% to about 25% of the overall packaging film gauge thickness and overlying and abuttingly contacting the second inner layer of the polyolefin so that the second inner layer of polyolefin is positioned between the first and the third outermost layers of elastomer, the shrink-wrap packaging film having enhanced optical and mechanical properties for the overall packaging film gauge thickness to allow the product to be seen more clearly through the packaging film and to increase modulus for the packaging film, the enhanced mechanical properties comprising a measurement of shrink in a transverse direction in a range of about 0% to about 60% and in a machine direction in a range of about 60% to about 90%, a tensile modulus in a range of about 50,000 psi to about 120,000 psi, and a tensile strength in a range of about 2000 psi to about 3500 psi, the enhanced optical properties comprising a haze in a range of about 1% to about 10% so that the packaging film is clear and the product can be seen easily through the shrink-wrap packaging film once the packaging film is heated to securely restrain the product with the shrink-wrap packaging film.
