Abstract: This invention relates to a multilayer biodegradable film which is particularly suitable for the manufacture of packaging and is also characterised by appreciable optical transparency properties in addition to high level mechanical properties.

Abstract: A machine for packaging groups of tissue products including a dosing element equipped with a plurality of passageways each configured for receiving a row formed by a predetermined number of products for defining a layer of a group of products. A detection device associated with the dosing element detects a filling parameter relative to a number, dimension and/or orientation of the products occupying the passageways and generates a signal representing the filling parameter. A processing and control unit receives the signals representing the products and processes the signals to compare with signals relating to a reference layer for deriving an acceptance condition, wherein the layer is consistent with the reference layer and suitable for the packaging, or for eliminating the layer of products released from the dosing element. A rejection system ejects the layer when it is in the eliminating condition.
