盛益昌包装，2011。

A folding box is a type of packaging box designed through folding, which can be unfolded and folded, usually made of cardboard, plastic, or other lightweight materials. They can be folded into flat plates during transportation and storage, greatly saving space. When in use, simply unfold and lock the structure according to the preset creases to form a sturdy container. This packaging form not only provides convenient carrying and storage solutions, but also greatly reduces transportation and storage costs. Folding boxes have a wide range of applications in various industries, including food, beverages, electronics, toys, cosmetics, and pharmaceuticals. They are not only used for product sales packaging, but also commonly used for transportation packaging to protect products from damage. In the long run, folding boxes are an economical packaging option. Their production costs are relatively low, and due to their foldable nature, transportation and storage costs are effectively controlled. This enables companies to reduce overall packaging costs while maintaining product quality. With the increasing demand for environmental protection and convenience among consumers, foldable boxes have broad market prospects as an innovative packaging solution. When choosing packaging solutions, enterprises should consider the advantages of folding boxes to achieve the dual goals of economic benefits and environmental responsibility. Through continuous technological innovation and design optimization, folding boxes are expected to play a greater role in the future packaging industry. The environmental characteristics of folding boxes are mainly reflected in their materials and production processes. Most folding boxes use recyclable or biodegradable materials, such as kraft paper, corrugated cardboard, etc., which can be easily recycled or naturally decomposed at the end of their service life, reducing their impact on the environment. In addition, due to the small space occupied by the folding box during transportation, it also reduces carbon emissions during transportation. The design of folding boxes is flexible and diverse, and can be customized according to the shape and size of the product. They can be designed as closed boxes with lids or as open trays to accommodate different packaging needs. In addition, folding boxes can enhance brand image and attract consumer attention through printing and decoration.
