Abstract

The invention discloses a fruit preserving carton, wherein a coating layer is coated on the inner surface of the carton, a cold storing agent powder layer is uniformly scattered on the coating layer, then a selective permeable thin film is stuck on the inner surface of the cold storing agent powder layer, and an oxygen absorbent, a carbon dioxide absorbent, an ethylene absorbent and a water absorbent are respectively uniformly flatly laid and placed on the upper surface of a top paperboard cushion layer. The invention further discloses a carton preserving and storing method utilizing the fruit preserving carton, and the method comprises the following steps: placing fruits among partitions of the carton; then laying the top paperboard cushion layer on a paperboard spacing sleeve; uniformly flatly laying packaging bags filled with the oxygen absorbent, the carbon dioxide absorbent, the ethylene absorbent and the water absorbent respectively on the top paperboard cushion layer; and finally sealing the bottom and top of the carton in which fruits are well loaded. By utilizing the fruit preserving carton and the carton preserving and storing method, the preserving and storing quality of the fruits can be significantly improved, the preservation period is prolonged, requirements of food hygiene can be completely met, storage and transportation can be carried out conveniently, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of fruit fresh-keeping storage and transportation packaging, relates to a fruit fresh-keeping carton, and also relates to a fruit fresh-keeping storage method utilizing the carton. Background technique [0002] In the integrated logistics chain of packaging, storage, transportation, and sales of fruits (such as apples and kiwis), the fresh-keeping storage and transportation packaging method is the core technology, which directly affects the edibility, commerciality, storage period and shelf life of the fruit. [0003] In fruit production areas, fruit farmers usually use traditional methods (such as earthen kiln storage method, urn storage method, cold room storage method, etc.) to store fruit, which has poor fresh-keeping effect, small storage scale, and short storage period, which cannot meet the needs of modern transportation and logistics. . In addition, plastic film fresh-keeping bags are also used to s...
