Modern gift box packaging has a single structure and a variety of refurbishment situations. As the most commonly used paper packaging product, corrugated cardboard boxes have been constantly developed and renovated in their construction process. High strength corrugated composite boards, as refurbished products, have changed the traditional horizontal arrangement structure of corrugated cardboard and adopted a vertical and tight arrangement structure of corrugated cardboard. They can replace heavy-duty corrugated cardboard, honeycomb cardboard, and high-end gift box packaging made of wood, and can be called a new type of environmentally friendly packaging material. As a cardboard box for product packaging, improving its waterproof performance is particularly important.
The waterproof and moisture-proof performance of some conventional corrugated cardboard boxes is relatively poor, and there are significant difficulties and difficulties in using recycled film coated cardboard boxes. The new type of recyclable waterproof cardboard box can improve its waterproof and moisture-proof performance by incorporating hydrolyzable resin. When recycled, it is easily degraded, making it a fantasy process to replace laminated cardboard boxes. It can be said that the renovation of modern product packaging structure is shifting from simple sales packaging and transportation packaging to functional packaging structure. Nowadays, the corrugated cardboard box renovation process with anti-corrosion features has emerged. The inner layer of high-end gift boxes is coated with special materials, which can allow the items inside to be fully preserved for more than 5 years without other anti-corrosion methods. This function is derived from the highly active copper element network, It can effectively neutralize corrosive gases. With the slowdown of China's circular economy pace and the renovation of paper product structure and consumption techniques, it will be carried out in the direction of beneficial ecological protection, energy conservation, material saving, consumption reduction, economy, and simplicity. Using paper instead of wood, paper instead of plastic, paper instead of glass, and paper instead of metal will become the mainstream of modern and future commodity packaging.
