In order to make full use of natural resources and reduce the cost of mail and transportation as much as possible, the production of a variety of paper with low quantities, cardboard and packaging boards are the development trend of paper products in the world.

Quality lightweight of packaging paper, cardboard and box board

In order to make full use of natural resources and reduce the cost of mail and transportation as much as possible, the production of a variety of paper with low quantities, cardboard and packaging boards are the development trend of paper products in the world. Low quantities of newsprint, relief printing paper, offset printing paper and paper bag paper have been raised and solved in China.

We should also achieve quality lightweight and variety diversification in packaging paper and paperboard products. Especially for the corrugated base paper and kraft carton paperboard with the largest consumption, according to the large demand for high-grade packing boxes in the domestic market, three low-quantity products should be added on the premise of improving the quality of the original products, that is, one variety of corrugated base paper should be added, and two varieties of kraft cardboard should be added, that is, one variety of corrugated base paper should be added, and the other two varieties of kraft cardboard should be added.

Developing functional packaging cardboard for food packaging

At present, there is a single variety of Whiteboard in our country, and there is no special food packaging board for different food needs. Although there are regulations on the raw materials and hygienic indexes of food packaging paper in China, there are no special varieties of cardboard used for food packaging. Grey white cardboard is used in many food boxes.

Owing to the non-oil-resistant property of the packaged cardboard for the direct-imported foods such as pastry boxes and fast food boxes, the phenomenon of oil leakage is quite common after the oily foods are packed. In the future, special functional cardboard should be developed for packaging different foods, such as carton cardboard for directly imported foods such as pastries, canned cardboard for packaging semi-finished products for steaming and baking, canned cardboard for packaging milk and fruit juice, etc.

Development of plant fiber snack box

With the increasing awareness of environmental protection and the actual needs of life, disposable paper fast food boxes and other food packaging products are welcomed. But paper fast food boxes are expensive, so it is necessary to develop fast food boxes with straw, wheat straw, bagasse, chaff and other crop fiber as raw materials. These products are competitive in price. They can be used to raise fertile soil after degradation. They can also be collected as livestock feed. The resources are fully utilized and have good economic and social benefits.
