High quality and lightweight packaging paper, cardboard and box board paper

In order to make full use of the natural resources and reduce the cost of post and transportation, it is the development trend of paper products in the world to produce a variety of low quantitative paper, cardboard and box cardboard. China has put forward low quantitative problems in newsprint, letterpress and offset printing paper, paper bag paper and so on, and has begun to solve them. High quality, lightweight and variety should also be realized in packaging paper, cardboard and other products. Especially for the corrugated base paper and kraft linerboard paper, according to the large demand of domestic market for high-grade packing boxes, three low-quality products should be added on the premise of properly improving the quality of the original products, namely, one new variety of 100g / ㎡ for corrugated base paper, 21g / ㎡ for kraft paperboard and 200g / ㎡ for kraft paperboard.

Research and development of functional special cardboard for food packaging

At present, there is a single variety of white board paper in China, which is not classified for different packages, 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 is no special type of paperboard for food packaging. Many kinds of food boxes use white paper with gray background. Because of the lack of oil-resistant property, the oil seeping phenomenon is very common after the oil-containing food is packed. In the future, we should develop and produce functional special cardboard for packaging different foods, such as the cardboard for packaging directly imported foods such as cakes, the cardboard for packaging semi-finished products such as steamed and baked foods, the cardboard for packaging milk, fruit juice, etc.

Development of vegetable fiber fast food box

With the enhancement of people's awareness of environmental protection and the actual needs of life, disposable paper fast food boxes and other food packaging products are popular. However, the paper fast food box has a high cost, so it is very necessary to develop a fast food box with straw, wheat straw, bagasse, chaff shell and other crop fibers as raw materials. This kind of product is competitive in price. After being used and degraded, it can raise fertile soil in the field. When collected, it can also be used as livestock feed. The resources are fully utilized, which has good economic and social benefits.
