Abstract

The invention relates to a room-temperature fresh keeping packaging box for juicy peaches and belongs to the technical field of packaging products. The room-temperature fresh keeping packaging box for the juicy peaches comprises an upper cover and a lower box, wherein the paper base material inner layer of the upper cover is coated with a polymer W film layer; the paper base inner layer of the lower box is sequentially coated with a polymer OC film layer and a buffering material layer from the inner side to the outer side; and vent holes are formed in the top surface and the four side surfaces of the upper cover and the bottom surface and the four side surfaces of the lower box. The shelf life of the juicy peaches packaged by the room-temperature fresh keeping packaging box for the juicy peaches reaches 6-12 days, the juicy peaches are ruddy and are full of juice, and the fragrant flavor of the juicy peaches is still kept.

Description

technical field [0001] The invention relates to a fresh-keeping packaging box, in particular to a normal-temperature fresh-keeping packaging box for juicy peaches, a preparation method and application thereof, and belongs to the technical field of packaging products. Background technique [0002] Peach has soft flesh, thin skin, bright color, juicy and sweet taste, and rich aroma, but it softens quickly after ripening, making storage and transportation very difficult. At present, there are three main types of fresh-keeping methods for peaches: 1) cold storage method: store at -0.5°C to 0°C and a relative humidity of 90%, but chilling damage is very prone to occur; Humidity is 85%~90%, the volume fraction of carbon dioxide is 5%, and the volume fraction of oxygen is 1% and preserves in the atmosphere environment, and storage cost is higher, and equipment investment is bigger; 3) chemical treatment method: this method can cooperate with In the above two processes, the peaches...
