Sažetak
With the aim to preserve food freshness and prevent it from further microbial contamination after bag opening, the multipurpose bag clips were designed and various designs of the bag clips can be found on the market. Once the plastic bag is open, it is not possible to close it again without an additional tool. A review of the market and available literature has identified the potential for the redesign of the existed bag clip in terms of geometry optimization concerning the technological design guidelines of polymers and recyclability and to show the design process of such products. Applying the design theory guidelines, Autodesk Fusion 360 and SolidWorks as tools, and product life cycle assessment (LCA), a polymeric multi- purpose bag clip was designed to the level of a functional prototype. The bag clip consists of four parts, two frames, an insert, and a closure. It is intended for closing and opening candy bags, snacks, and freezer bags. The prototype of the bag clip was 3D printed and functionality was successfully tested. The final product has a mass of 32% less than the initial and it is fully recyclable. According to the LCA, the disadvantage of the proposed bag clip is the high energy consumption for its production
