A recently granted patent (Publication Number: US11866235B2) discloses a unique blank for producing three-dimensional structures made of paper, cardboard, or plastic, such as packages. The blank includes lateral surfaces and bottom/cover tabs connected by mechanically produced creasing lines that displace material without removal. Additionally, grooves formed by a laser intersect with the creasing lines to absorb residual stresses, enhancing the structural integrity of the final product. The grooves can be arranged in decorative patterns or different partial surfaces, providing versatility in design.

Furthermore, the patent extends to the three-dimensional structures and folding boxes produced using the innovative blank. These structures, suitable for storing goods like cigarettes, feature lateral walls connected by creasing lines and grooves produced by lasers. The grooves not only enhance the aesthetic appeal by forming decorative patterns but also contribute to the overall strength and durability of the folding boxes. With the ability to customize the grooves in various shapes and arrangements, the patented technology offers a novel approach to creating visually appealing and structurally sound packaging solutions for a wide range of products.
