Therefore, large-scale studies are conducted and implementation of intelligent packaging. The operation of these packages is the use of interactive, the most colorful indicators to assess the quality of the packaged product. Methods: This article describes intelligent packaging technologies and presents research for different types of oxygen indicators. Results and conclusion: Indicators for the detection of oxygen allows the consumer to provide some information on the suitability of the product for consumption. Apart from that, they are a simple tool that allows you to reduce the costs associated with loss replacement, repair damaged products or their disposal.
