    摘要： A multilayer, heat-shrinkable film has a first layer that is an outer film layer and that serves as a heat seal layer, and a second layer comprising at least one semi-crystalline polyamide. The first layer contains at least one member selected from the group consisting of (i) polyolefin having a density of from 0.88 g/cm3 to 0.917 g/cm3, and (ii) ionomer resin. The second layer contains at least one semi-crystalline polyamide selected from the group consisting of polyamide 6, polyamide 66, polyamide 6/66, and polyamide 6/12, with the semi-crystalline polyamide making up at least 50 weight percent of the second layer. The film has a total free shrink at 185° F. of at least 35 percent. The film has a total semi-crystalline polyamide content of at least 35 volume percent. The multilayer, heat-shrinkable film exhibits a percent haze as measured using ASTM D 1003-00, and a percent transparency as measured using ASTM D 1746-97, in accordance with the following equation: % Transparency≧5.33 (% Haze)−31.5 The multilayer, heat-shrinkable film can be used to make a packaging article.

    摘要： 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.
