Sustainable packaging requires the encouragement of consumers to conscientiously separate waste, especially packaging, which is an essential source of raw materials. The study focuses on multifunctional gift packaging and emphasizes sustainable design. It is based on a mixed-method approach, involving a review of literature, case studies, and user research.
The dissertation is divided into five sequential parts. The research results from the first part were used as the foundational basis for the second part, and so on. Preliminary research found that consumers best separate monomaterials, which are also the most suitable for recycling. Corrugated cardboard was chosen for gift packaging, representing one of the most sustainable monomaterials. Several types of commercially-used corrugated cardboard were analyzed, and their fundamental and mechanical properties were determined. Using thinner, lighter corrugated cardboard made from recycled fibers proved to be a better choice from an environmental perspective, even though it has slightly inferior mechanical properties compared to the sample with the best mechanical properties.
The process continued with structural design, where a uniquely shaped packaging was selected. The main purpose of this special packaging shape is to use its form to create a comprehensive brand image. Elements of multifunctionality and the possibility of re-use were added, and opinions and usage were researched among respondents and focus groups. During the research, an opportunity was identified to use this concept for the local brand "Bled Local Selection", which brings together local producers and craftsmen. The graphic image of the gift packaging was conveyed through labels, as they allow better adaptability for the personalization of different brands. The packaging also featured interactive functionalities, such as QR codes, RFID tags, and Augmented Reality (AR). The inclusion of printed electronics was tested; it was found that it does not significantly affect the recyclability of the packaging, and has a minimal impact on the recycling process.
Design guidelines for interactive sustainable gift packaging include steps that facilitate the transfer of knowledge to the economy, offer a set of starting points for further research, and highlight important aspects of sustainable design in line with increasingly stringent environmental regulations in a circular economy.
