Nowadays, among the four pillar packaging materials of paper, plastic, metal and glass, Tianjin paper products are developing rapidly. Its price is very cheap, and it can be recycled while maintaining a green environment. Now the development of packaging materials in China has the following points.

Research and development of functional paperboard for food packaging

At present, the variety of Whiteboard in China is single, there is no classification for different packaging materials, 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 kinds of paperboard specially used for food packaging. Due to the non oil resistance of the packaging paperboard for pastry box, fast food box and other direct entry food, the phenomenon of oil leakage is quite common after packaging oily food. In the future, special functional cardboard should be developed and produced for different foods, such as cartons and paperboards for directly imported foods such as cakes, paper cans and paperboards for semi-finished foods for steaming and baking, and paper cans and paperboards for milk and fruit juice.

Research and development of natural green packaging materials

Natural plant fibers (straw, wheat straw, cotton stalk, chaff, etc.) can be used as fast food boxes, and can also be rolled or woven into convenient bags. Some natural plant fibers are long and strong, and can be easily woven into straw bags. Bamboo, natural shrubs, wicker, etc. can also be woven into baskets, baskets and other packaging containers or made into natural bamboo tubes to hold fruits, vegetables, tea, etc, The bamboo plywood packing box can be used for the transportation and packaging of machinery, electrical appliances and other equipment. Natural mineral materials such as clay, ceramics can be made into wine, tea, etc. packaging, rock particles will be expanded into light weight perlite, adding a little adhesive, can be made into different shapes of cushioning packaging.

Development of plant fiber fast food box

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

Among the numerous packaging materials, paper products are developing rapidly, and quality and price are the first choice. We learned about the development trend of some paper products, summed up to share with you.

High quality and lightweight packaging paper, paperboard and containerboard

In order to make full use of natural resources and reduce the cost of mail and transportation as much as possible, it is the development trend of paper products all over the world to produce a variety of paper, paperboard and packaging paperboard with low quantity. China has put forward the problem of low ration in newsprint, relief and offset printing paper, paper bag paper and so on, and has begun to solve it. In packaging paper and paperboard and other products should also achieve high quality lightweight and variety diversification. In particular, corrugated base paper and kraft liner paper with larger consumption should be added with three low quantitative products on the premise of properly improving the original product quality according to the large demand for high-quality packaging boxes in the domestic market, that is, corrugated base paper should be added with a variety of 100g / m2, kraft paperboard with two varieties of 21g / m2 and 200g / m2.

Development of straw pulp based disposable tableware special cardboard

The main technical features are as follows:

(1) Based on China's raw material resources, aiming at the shortcomings of straw pulp raw materials, this paper adopts the optimization application technology of chemical additives to improve the quality of straw pulp, so as to ensure that its performance is close to the physical properties of wood pulp.

(2) The surface of the paperboard is treated for food packaging, so that the finished paperboard has the functions of hot water resistance, non leakage, non stratification, oil resistance and heat sealing. The economic and reasonable method is to use the original bleached straw pulp to produce paper tableware, and then recycle the waste tableware to produce non food packaging paper, so as to make full use of fiber resources without polluting the environment and increasing the pulping load.
