The irregularly shaped packaging box with a window is designed in the three-dimensional shape of a house. The front and top of the packaging innovatively adopt a transparent window design, allowing the shape of the contents to be intuitively presented without opening the package. This not only meets consumers’ “visualization” expectations for product quality but also creates a differentiated memory point for the brand. The material used is environmentally friendly cardboard, and corrugated paper can also be adopted to enhance anti-drop performance. It is suitable for various scenarios such as fruit gift boxes, baked pastries, and cultural and creative gifts, empowering the improvement of product value through creative design.
