    摘要： A heat-shrinkable bag has a means for initiating a manual tear that can be propagated to open the bag and allow a product to be readily removed therefrom, without the use of a knife or scissors or any other implement. The bag is made from a heat-shrinkable multilayer film having a Peak Load Impact Strength of at least 50 Newtons per mil. The means for initiating tearing results in a first tear in the first side of the bag, and a second tear in the second side of the bag. The first tear and the second tear are each capable of being manually propagated through a heat seal and across the bag, or down the length of the bag, with the tear being capable of being manually propagated through and to an opposite bag edge, so that the product inside a package can be readily removed from the bag. A process for making a package and manually opening the package, comprises placing a product inside the bag, sealing the bag closed, shrinking the film around the product, manually initiating and manually propagating the first and second tears, and readily removing the product from the bag.

    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.
