Nowadays, eco-design of products is becoming one of the most important directions at packaging development. Efficient use of materials, use of materials from renewable sources, design for recycling and reuse are especially important. In our research, we were interested in the development of sustainable, biodegradable protective paper packaging. In order to make packaging resistant against water, paper was coated with a biodegradable biopolymer, instead of using synthetic polymer. The base packaging paper was coated with a PLA solution, which was obtained by dissolving PLA pellets in dichloromethane. Two different concentrations were used. Technological and surface properties of coated paper were determined. The results of analyses have shown that sustainable packaging paper with good surface properties and barrier against water can be obtained by coating it with a PLA solution. Comparison with a commercial packaging paper has shown, that for PLA coated paper even higher water resistance was obtained.
