Modern gift boxes have a single structure and a variety of renovations. As the most rarely used paper packaging product, the structural situation of corrugated box has also been developed and renovated in the process of application. As a renovated product, high-strength corrugated composite board changes the corrugated horizontal arrangement structure of traditional corrugated board, and adopts the corrugated vertical tight arrangement structure, which can complete the packaging of high-end gift boxes instead of heavy corrugated board, honeycomb board and wood, and can be called a new type of environmental protection packaging materials. As a kind of product outer packaging carton, it is particularly important to improve its waterproof performance.
The waterproof and moisture-proof properties of some corrugated boxes are relatively poor, and it is difficult to regenerate and use cartons covered with film. The new recyclable waterproof carton, by adding hydrolyzable resin, the waterproof and moisture-proof performance of the carton can be better improved, and it can be easily degraded when recycled. It is an ideal process to replace the film coated carton.
It can be said that the renovation of modern product packaging structure is changing from the simple sales packaging and transportation packaging in the past to the functional packaging structure, and now the corrugated box renovation process with anti-corrosion characteristics has come out. The inner paper of high-grade gift box is coated with special materials, which can keep the items in the box for more than 5 years without other anti-corrosion methods. This function comes from the highly active copper element, which can effectively neutralize the corrosive gas.
With the slowdown of the development of circular economy in China, the renovation of the structure of paper products and consumption skills will be carried out in the direction of beneficial ecological protection, energy conservation, material saving, consumption reduction, economy and simplicity. Replacing wood with paper, plastic with paper, glass with paper and metal with paper will become the mainstream of commodity packaging in modern and future times.
