An apparatus for reducing wrinkles in a film includes a first pair of cylindrical rollers including a first roller and a second roller, the first and second roller each in parallel juxtaposed relation to each other, and each having a substantially smooth surface; and a second pair of cylindrical rollers including a third roller and a fourth roller, the third and fourth roller each in parallel juxtaposed relation to each other, and at least one of the third and fourth roller having a chevron pattern disposed on the surface thereof; the first pair of rollers being adjacent to and spaced apart from the second pair of rollers. A method for reducing wrinkles is also disclosed herein.

A method and apparatus for enclosing a product in a tray having an outwardly extending flange is provided. A permeable web is secured to an inner periphery of flange and the secured portion is severed from the web to form a permeable lid. An impermeable web is then secured to an outer periphery of the flange and then severed from the web to form a peelable, impermeable lid. The outer periphery of the flange is protected from damage when the permeable lid is severed from the permeable web by elevating the permeable web above the outer periphery of the flange and severing the web at the elevated portion. If a fresh red meat product is to be packaged, the tray may be at least partially evacuated and then at least partially filled with a gas which is lower in oxygen content than air. Prior to retail sale, the impermeable lid may be removed to cause the packaged meat product to bloom to a red color.

A method and apparatus for improving transverse seal strength in a vertical form-fill-seal machine includes directing a cooling medium on a just formed transverse seal from an area beneath and on either side of the film, in an arcuate pattern to effect cooling during at least a portion of the downward movement of the seal toward a cutting means.
