Nanometer freshness retaining paper box at room temperature

Abstract

The present invention provides a nanometer freshness retaining paper box at room temperature. The nanometer freshness retaining paper box comprises a box body and a plurality of ethylene absorption cloths arranged in the box body, an inner surface of the box body is coated with a nanometer freshness retaining layer, the nanometer freshness retaining layer comprises the following raw material components: nanometer diatomaceous earth, sodium bicarbonate, polyethyleneimine, an antibacterial agent and deionized water, and surfaces of the ethylene absorption cloths are successively coated with a water content evaporation inhibitor and an ethylene adsorbent. By a reasonable box body interior design and a ratio of coating materials, the nanometer freshness retaining paper box effectively improvesa preservation effect of fruits and vegetables at room temperature, significantly improves oxidation preventing, micro-organism preventing, corrosion preventing, water retaining and freshness retaining abilities, can extend the shelf life of different varieties of agricultural products for 3-20 days, and has a good market promotion value.

Description

technical field [0001] The invention relates to the technical field of fruit fresh-keeping cartons, in particular to a nanometer room-temperature fresh-keeping carton. Background technique [0002] As the personalized demand for commodities becomes more and more widespread, functional corrugated boxes are attracting more and more attention. The so-called functional corrugated boxes refer to packaging containers with special functions made of corrugated cardboard, which generally have many advantages, such as Light weight, good structural performance, scientific and environmental protection, etc., its internal corrugated structure is similar to an arched structure, which can play a role in cushioning and shock absorption for the packaged products, and has good mechanical properties. At the same time, it has many good protection functions for packaged items, such as moisture-proof, heat dissipation, fresh-keeping, refrigeration, easy handling, etc., lower transportation costs,...

AI Technical Summary

Problems solved by technology

At present, the existing fruit and vegetable fresh-keeping cartons generally place fresh-keeping agents in the cartons, but the fresh-keeping range is small, difficult to control, and the fresh-keeping is uneven, and it is still prone to spoilage and deterioration. In recent years, there are also some coating fresh-keeping technologies, namely in The surface of fruits and vegetables is coated with an edible film that has a fresh-keeping effect, but there are still many problems, such as the thickness of the coating is not easy to control, the drying time is too long, and it is easy to breed microorganisms, etc., and the coating on the surface of fruits and vegetables is not easy to be accepted by consumers
