Abstract: The invention relates to the monitoring of products by means of active radio tags. According to the invention, packagings of products are provided with an active radio tag that detects at least one environmental condition and/or at least one packaging state, and which emits a signal at time intervals, which provides information about a unique identifier and at least one state in which the respective product is found. The signal is picked up by a receiver that extracts the unique identifier and the state information and transmits same together with location information to an external server.

Abstract: A process for making a soft, strong cellulosic sheet weighing from about 2 to about 15 pounds per 2880 sq. ft., comprising selectively treating a face surface of a cellulosic fibrous web with a dilute aqueous solution of a chemical debonding agent in an amount effective to soften a surface zone of the web proximate the treated face surface, whereby a composite strong zone/soft surface zone structure results, with the soft surface zone thereof including the treated face surface and being from about 10 to about 40% of the total thickness of the web, and with the strong zone being effectively untreated by the agent. The cellulosic sheet made by this process is characterized by a strong inner surface zone of from about 50 to about 90% of the total thickness of the sheet, and a soft and pleasing-to-the-touch outer surface zone comprising the remainder of the thickness of the sheet.
