### Packaging and Label Design  
Implementing eco-design was the guiding principle for construction solutions in drafting multipurpose and reusable gift packaging. The basic packaging design was taken from the FEFCO box styles, specifically folder type 0427 and telescope type 0331, which were modified to strengthen the box on one side or at the bottom or top. Seven versions of the packaging were then designed in such a way that each version was upgraded [1; 8]. The final version of the packaging was designed by drafting with parametric components from a single piece of board, which was then further developed into a more complex shape. The unconventional packaging design was achieved using structural elements of a folder-type box. The final shape of the packaging was developed through an iterative design process based on modified FEFCO 0427 and 0331 box styles to ensure durability, material efficiency, and ease of assembly. Packaging sizes were optimized for efficient material utilization, minimizing waste from the B1 format sheets while maintaining compatibility with various products such as spirits, confectionery, and specialty goods [1; 8]. Composed of three pieces, it was an easy-to-assemble box without the need for glue. The simplification and recyclability approach eliminated lamination and adhesives, ensuring that the single-wall E-flute corrugated cardboard used was 100% recyclable. To enhance functionality, the handle was constructed from reinforced corrugated cardboard, eliminating the need for an additional gift bag. A retractable handle made from corrugated cardboard was incorporated into the basic packaging structure, as shown in Figure 2a. The gift packaging was designed to accommodate various products by simply adding different interior fittments. Additionally, modular interior fittments allowed secure placement of different product types, preserving both the aesthetics and structural integrity. By utilizing boxes of different shapes, volumes, and dimensions, an exhibition product display was created, which could also serve as a promotional stand (Figure 2b). After fulfilling its primary purpose, the packaging can be repurposed as a nesting box for solitary bees, enabling sustainable reuse. This transformation was achieved by adding perforations to the front and back sides of the packaging (Figure 2c). A total of four different bottle label designs (Figure 3) and interactive packaging labels presented in two different layouts--vertical and horizontal (Figure 4)--were developed. The label design followed eco-design principles by minimizing ink use through monochromatic printing, utilizing cut-out logo designs to reduce material consumption, and employing FSC-certified biodegradable paper. The selection of FSC-certified paper and biodegradable labels aligned with the principle of choosing materials for recyclability, ensuring sustainable material use and minimal environmental impact. More detailed descriptions of the labels can be found in previous publications [1; 28]. These designs were created based on the existing visual identity of the Tr'glay brand while adhering to eco

Tr'glav is a premium Slovenian brand, a small, traditional, family-run distillery from Bled specializing in spirits with a long-standing heritage passed down through generations. In line with its commitment to sustainability, the brand follows an eco-design approach focused on minimizing environmental impact by utilizing locally sourced ingredients, maintaining small-scale sustainable production, and implementing economical packaging solutions. The packaging was made from fully recyclable materials, while the glass bottles could be returned and refilled, supporting a circular economy model which reduces waste and promotes resource efficiency. The commitment to eco-design extended to the bottle labels as well.
