Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging boxes, and specifically relates to a packaging box. Background Technology
[0002] With the rapid development of the commodity economy and the increasing demands of consumers for product appearance, packaging boxes, as an important component of commodities, not only serve the function of protecting goods but also directly influence consumers' purchasing decisions. Traditional packaging boxes are mostly made of a single paper material, with simple structure and limited function, making it difficult to meet the modern market's demands for diversified, personalized, and environmentally friendly packaging boxes.
[0003] Currently, common packaging boxes on the market suffer from insufficient functionality. Traditional packaging boxes typically only provide basic containment and protection, lacking additional features such as ease of opening and reusability, making it difficult to meet the packaging needs of special or high-end products. For example, the lid and bottom of the packaging box need to be sealed with tape. When it is necessary to open the packaging box, the tape on the lid needs to be torn off. Because the tape adheres strongly to the lid, tearing off the tape can easily damage the appearance of the packaging box, affecting not only its reusability but also making it difficult to open.
