Alarmed closable packaging for pallets

Alarmed closable packaging apt to be applied to a container of goods, made in two separate sections whose edges are provided with closure elements and which, once brought into contact, completely wrap and seal the container of goods, wherein said sections are formed as multilayers comprising at least one first electrically conductive layer, a second electrically conductive layer and an electrically insulating layer placed between said two conductive layers, said electrically insulating layer having such a composition as to recover said electrically insulating layer's thickness after having undergone crushing;

• wherein:
• a support is applied to each of said sections containing at least two conductive attachments, at least one of said conductive attachments being connected to a first of said conductive layers and at least one of said conductive attachments being connected to the second of said conductive layers;
• one electronic device, equipped with one low voltage source and with at least four electrodes, is applied to both sections of the closable packaging by means of said supports, at least two of said electrodes coming into contact with respective ones of said conductive attachments of each support in order to create a continuous low voltage on said first electrically conductive layer of each section and at least two of said electrodes coming into contact with respective ones of said conductive attachments of each support in order to create a continuous low voltage on said second electrically conductive layer of each section;
• said electronic device also acts as a transmitter of a signal to a receiver and is apt to record the change in voltage inside the multilayer section in response to impacts or tears in the closable packaging or to unauthorised removal of the same device from the device's support and to report this event to said receiver.
