In this diploma thesis we aimed to develop a completely ecological packaging, consisting of cardboard and corrugated cardboard, which would have insulating properties for the transport of temperature-sensitive foods, in our case fresh fish. The aim and goal of our diploma thesis was to develop fully ecological packaging. In the theoretical part, we divided the packaging into individual segments, where it belongs today and what role it plays in modern society. We have described the basic materials used for our product. We reviewed the market for similar products and found that in most cases certain parts of non-ecological elements such as polyethylene and polystyrene are still used. We have replaced these elements with an advanced ecological dispersion varnish. The main feature is a barrier that creates a waterproofness and at the same time is certified for direct contact with food. To test the materials and consequently choose the most suitable one, we chose two corrugated cartons for the outer wrapper, which will consist of a lid and a bottom, and two classic cartons for the inner part. In the experimental part, we tested the basic properties, surface properties, mechanical and structural properties of the mentioned cartons. Mean values, standard deviation and coefficient of variation were calculated. For the production of packaging, we chose sample V1 from corrugated cardboard for the outer wrapper with a weight of 592 g/m2 and sample V4 from classic cardboard with a weight of 300 g/m2 for the inner insert. The final products were designed in the Artios CAD program, and the cut-outs themselves on a Esko Kongsberg cutter. We have successfully developed and produced ecological packaging, with mentioned cardboards. Therefore, finished packaging has great potential in the market, but some improvements would be needed.
