Moisture-holding type packing box for storing fruits and vegetables

Abstract

The invention discloses a moisture-holding type packing box for storing fruits and vegetables. The moisture-holding type packing box for storing the fruits and the vegetables comprises a box body, a moisture-holding breathing separating plate and a water holding bag body, wherein the moisture-holding breathing separating plate is parallel to the bottom surface of the box body and is arranged at the bottom part of the box body; the water holding bag body is arranged into a chamber body which is formed through the moisture-holding breathing separating plate and the bottom part of the box body; aplurality of breathing holes are formed in the upper surface of the moisture-holding breathing separating plate; a plurality of through holes are formed in the top part of the box body; a waterprooflayer is arranged on the inner sidewall of the box body; and the water holding bag body is detachably connected to the box body. According to the moisture-holding type packing box for storing the fruits and the vegetables, the water holding bag body is arranged at the bottom part of the box body and is capable of continuously releasing water vapor during transporting and storing, so that sufficient humidity in the packing box is ensured, and as a result, the fruit and vegetable fresh-caring effect is achieved. With the adoption of the moisture-holding type packing box for storing the fruits and the vegetables, a special moisture-holding medium is saved; and a moisture-holding bag body can be recycled, so that the effect of holding moisture to realize fresh caring of the fruits and the vegetables with low cost can be achieved.

Description

technical field [0001] The invention relates to the field of carton packaging, in particular to a moisture-retaining packaging box for fruit and vegetable preservation. Background technique [0002] Cartons are widely used in warehousing and logistics. In recent years, with the rapid development of e-commerce, fresh products such as fruits and vegetables have also been sold online. During the transportation of fresh products, freshness preservation is very important. The commonly used fresh-keeping method is to use dry ice or ice packs to keep the temperature in the box at a low temperature. However, for some fruit and vegetable products that do not need to be stored and transported at low temperature, the cost of this low-temperature preservation method is relatively high, resulting in a certain degree of waste. For fruit and vegetable products, an effective fresh-keeping effect can be achieved by maintaining sufficient humidity. However, there is currently no low-cost f...
