摘要： Molecularly oriented films, and compositions used therein, comprise blends of a first EVA copolymer having a relatively low VA content, and a second EVA copolymer having a relatively high VA content. The blend exhibits a balance of properties which permit ready processability for orientation, while affording high levels of strength, particularly at elevated temperatures. Consequently laminates may be produced which are well suited for shrink packaging of meat, especially when a high oxygen barrier resin provides one layer thereof.

摘要： The invention discloses an ink-based-image-bearing substrate. This substrate includes a coextruded thermoplastic film having at least one layer made from a polymer derived from polypropylene and another layer made from an acidic functional group-bearing polymer. The layer which includes the polymer derived from the polypropylene is oriented in at least the machine direction. The layer which includes the acidic function group-bearing polymer is the print-receiving layer. The acidic functional group bearing-polymer is preferably ethylene-acrylic acid or ethylene-methacrylic acid, and the acidic functional group-bearing polymer-containing layer has a softening point in a range of 180° to 220° F. Liquid toner ink is electrostatically printed on the layer which includes the acidic functional group-bearing polymer. Additionally, the invention includes a method for providing the ink-based-image-bearing substrate.
