Estimating the term…
A method for the production of plastic products includes a loading step in which plastic material in granular form is inserted in a containing element, and a heating step, in which the plastic material in granular form is heated until the melting temperature is reached. The method also includes an extrusion step in which the plastic material is conveyed toward extrusion means and extruded to form at least one layer of a film of plastic material and a printing step in which, by means of printing means, at least one layer of printing material is deposited on the film of plastic material to define information associated with the film of plastic material. During the printing step the printing means deposit electrically conductive material on the film of plastic material, according to a predetermined conformation able to define a predetermined electric circuit. The electric circuit comprises electronic memorization means configured to memorize at least predetermined information associated with the type of plastic product to be made.
A method for the production of plastic products comprising:
A plastic product for non-rigid containing elements, comprising at least one layer of plastic film, wherein said layer of plastic film comprises a printed portion in which information relating to the plastic film itself or to the use of the containing elements made with said plastic film is associated, wherein said printed portion comprises electrically conductive material, having a predetermined conformation defining a predetermined electric circuit, said electric circuit comprises electronic memorization means able to memorize at least predetermined information associated with the type of containing element.
An apparatus for the production of plastic products, comprising:
