摘要

A material (1a, 1b) composed of superimposed layers which are mutually anchored and separable, particularly for manufacturing, on automated lines, packagings, bags, envelopes, containers or the like. The material (1a, 1b) according to the invention comprises at least one first layer (2a, 2b) made of cellulose material and at least one second layer (3a, 3b) made of synthetic material. The first layer (2a, 2b) and the second layer (3a, 3b) are connected to each other by means of an adhesive which is interposed between the two layers (2a, 3a; 2b, 3b) and is arranged in mutually spaced adhesive bonding regions (4a, 4b).
