Abstract
A multilayer film, which is particularly suited to packaging of cheese on a Hayssen® RT packaging machine, has a first layer comprising cyclic olefin copolymer having a glass transition temperature of at least 125° C., and a second layer comprising at least one member selected from the group consisting of cyclic olefin copolymer having a glass transition temperature of at least 125° C., polyamide, polyester, and polystyrene. The first and second layers are on opposite sides of a tensile axis of symmetry of the film. The film exhibits from 0 to 45 degrees of transverse edge curl, a yield point of at least 1200 psi at a temperature of 85° C., and an elongation at break of from 0 to 300 percent at 85° C. In addition, a packaging process comprises supplying the film and placing a plurality of product units on the flat film at desired intervals, forwarding the flat film having product units thereon, while forming a tubing from the flat film so that product is inside the tubing, followed by sealing the film along its length and transversely (upstream and downstream of the product), so that the product is a discrete packaged product is formed.
