Problems solved by technology
The corrugated boxes used in current logistics usually have a single structure, and only some simple information is printed on the packaging. Because they cannot be reused, consumers often discard them as garbage after receiving the express delivery, which will cause serious damage. Resource waste and environmental pollution

The invention provides a waterproof color-changing corrugated board. The waterproof color-changing corrugated board comprises an inner-layer oil layer, an inner-layer waterproof layer, a corrugated inner paper layer, a corrugated core paper layer, a corrugated surface paper layer, an outer-layer waterproof layer, a microfibrillated cellulose coating layer, a color layer, an outer-layer oil layer and a color-changing layer which are sequentially stacked from inside to outside. The invention further provides a waterproof color-changing corrugated carton. The invention further provides a preparation method of the waterproof color-changing corrugated carton. The corrugated board has the beneficial effects that the damp-proof and waterproof performance of the corrugated board is improved, and the corrugated board can be used under the condition of high humidity or humid environment; and recycling can be achieved, and environmental protection is achieved.
Description
technical field [0001] The invention relates to packaging, in particular to a waterproof and color-changing corrugated cardboard, a waterproof and color-changing corrugated cardboard box and a preparation method thereof. Background technique [0002] With the rapid development of the logistics industry, paper product packaging containers are playing an increasingly important role, among which corrugated boxes are the most used paper product packaging containers in people's production and life. With the advantages of light weight, good cushioning performance, low cost, and easy logistics, corrugated boxes are used more and more widely. However, corrugated boxes are prone to moisture absorption and dampness, resulting in weakened strength, and various physical performance indicators will drop sharply after being exposed to water. Thus directly affecting the use effect and appearance of the carton, leading to an increase in consumer complaints. On the other hand, my country's ...
