ABSTRACT:
Food products, especially fresh food products such as retail-cut red meat, vegetables and fruits, are packaged with a film having at least one film layer comprising a substantially linear ethylene polymer, preferably a polymer comprising ethylene and at least one .alpha.-olefin comonomer, e.g. 1-octene. The ethylene polymers used in the construction of the film structures used in this invention are prepared by constrained geometry catalyst technology. The film structures can be either mono- or multilayered, oriented or nonoriented, oxygen permeable or impermeable, and prepared by any conventional technique. The food products can be packaged by any conventional method, e.g. stretch overwrap, shrink, vacuum skin, on vacuum forming.
