Description

TECHNICAL FIELD

[0001] The utility model relates to packing material technical field, concretely relates to a ventilative fruit packing box. BACKGROUND

Especially for the position of fruits in the carton, it cannot be effectively limited, and then the shaking condition may occur, causing the collision damage of fruits. When packing fresh fruits, vegetables and other fresh goods, these goods will produce carbon dioxide, water vapor and heat during storage and transportation.
