Description

Technical Field

[0001] The utility model belongs to the technical field of food packaging boxes, and in particular relates to an environmentally friendly and easy-to-open food packaging box. Background Art

[0002] For example, food packaging boxes are needed during the storage and transportation of fruits and other foods. Ordinary fruit boxes often focus on cost-effectiveness and convenience in design and material, but this also means that they have certain limitations in barrier properties and preservation functions. First, since the materials of most ordinary fruit boxes do not have good sealing properties, air and moisture can easily penetrate, which in turn accelerates the metabolism of fruits and causes them to rot prematurely. Secondly, fruits release ethylene gas during picking, transportation, and storage. This is a natural plant hormone that can promote fruit ripening, but it also accelerates the aging process of fruits. Ordinary fruit boxes have almost no effective control measures for this.

[0003] In addition, the shelf life of ordinary fruit boxes is relatively short. For some fruits that are not easy to preserve, such fruit boxes often cannot provide adequate protection. For example, some tropical fruits such as mangoes and bananas mature quickly and require specific environmental conditions to extend their shelf life. In this case, ordinary fruit boxes may not be able to meet these special needs, causing the fruit to deteriorate in a short period of time.
