AI Technical Summary
Existing aromatic corrugated cardboard boxes suffer from continuous aroma loss during storage and transportation, resulting in a short fragrance retention period, high production costs, difficulty in achieving long-term sealed fragrance storage and on-demand fragrance release, and incompatibility with existing corrugated cardboard box die-cutting equipment, leading to low production efficiency and low yield.
It adopts a combination of multi-responsive aromatic microcapsules and a peelable protective film. The microcapsules use a multi-layer wall structure with alternating temperature-sensitive and humidity-sensitive polymers. The fragrance-enhancing area is set at specific points and covered with a protective film. When the box is opened, the protective film is broken to release the fragrance. The fragrance-enhancing process is integrated with the die-cutting main line equipment.
It achieves effective fragrance locking at room temperature and releases fragrance on demand after environmental triggering, reducing production costs and the amount of microcapsule consumables used, improving fragrance retention time and user experience, adapting to existing production lines, and improving yield.
