Abstract

The invention provides a film, a package and methods for employing the same. The film has a first layer of an elastomer and a second layer of a polyethylene such as a single site catalyst polyethylene. The film can have a third layer of a polyethylene such that the second layer is disposed between the first and third layers. The polyethylene of the third layer also can be single site catalyst polyethylene and, the elastomer of the first layer can be styrene butadiene copolymer. The film has an oxygen transmission rate of up to about 1000, such as 150-450 cc/100 in.sup.2 /24 hr., typically 260-400 cc/100 in.sup.2 /24 hr., with values of 300, 350-360, 400 cc/100 in.sup.2 /24 hr. and even higher exhibited by the film. The film is suitable for packages, for instance, packaging for cole slaw and leafy salad. The film also exhibits excellent clarity, durability, seal strength and machinability.
