Description

A fruit and vegetable fresh-keeping carton with refrigeration function

technical field

The utility model belongs to the field of cartons, in particular to a fruit and vegetable fresh-keeping carton with a refrigeration function.

Background technique

As the most important agricultural and sideline products, vegetables and fruits are often packaged in cartons for storage and circulation in the market when they are stored and transported. In refrigerated trucks, and the existing cartons have certain defects when stored in refrigerated warehouses and refrigerated trucks. For example, two kinds of cartons are commonly used in the market now:

One is to use high-strength corrugated paper, core paper, kraft surface paper, and lining paper to compound "high-quality cardboard" in a conventional way, and then form it into a carton; it can be used for packaging under normal conditions, but it can be used in a refrigerator after stacking. It is very easy to collapse the box. The reason is that the water vapor formed on the inner wall of the carton gradually penetrates the paper of each layer of the carton from the inside out, causing the carton to soften due to moisture and cannot effectively protect the integrity of the vegetables and fruits in the box.

The second is to use appropriate corrugated paper, core paper, kraft paper, and lining paper to compound "ordinary cardboard" in a conventional way, and then "coat" the surface of the lining paper layer (the first layer of the inner wall of the box), and make it after molding. Cartons: It can be used for packaging under normal conditions, and it can also solve the problem of "collapsed boxes" after being stacked and used in refrigerators and freezers. However, the water vapor formed on the inner wall of the cartons is blocked by the "film" in the box, resulting in "water accumulation" in the box. It cannot effectively protect the freshness of fruits and vegetables in the box, or even rot.

Therefore, it is necessary to provide a fruit and vegetable fresh-keeping carton with a refrigeration function.
