Technology leads paper packaging

in order to make full use of resources and reduce the cost of mailing and transportation as much as possible, the production of low quantity paper, paperboard and packaging carton paperboard is the current development trend of paper products all over the world, which should increase the research and development of substitutes. China has put forward the problem of low quantity in paper, letterpress paper, offset printing paper and paper bag paper, and began to solve it. Among many uses of paper, packaging paper and paperboard should achieve high-quality lightweight and brand diversification. In particular, the corrugated base paper and kraft liner paper with the largest consumption should be added with three low quantitative products according to the large domestic demand for high-grade packaging boxes, that is, the corrugated base paper should be added with 100 g/m2 varieties, and the kraft board should be added with 210 g/m2 and 200 g/m2 varieties

research has a certain difficulty in the process of commercialization. Research on functional special cardboard for food packaging

at present, China produces a single variety of whiteboard, which is not classified to distinguish different packaging materials, nor does it point out that Liu Yanlong needs different functions of packaging materials for different foods to produce special food packaging cardboard. At present, in China, the cardboard used to pack directly imported food, such as pastry boxes and fast food boxes, has no oil resistance, so the leakage phenomenon is quite common after packaging oily food

in the future, we should develop and produce functional special cardboard for packaging solid food and packaging liquid food according to different food packages. The former includes cartons and paperboards for packaging directly imported food such as cakes, lightproof and moisture-proof paper cans and paperboards for packaging salt, and cartons and paperboards for packaging semi-finished food for steaming and baking processing; The latter, such as paper cans and cardboard for packaging milk, fruit juice, etc

develop pollution-free plant separation pulping and papermaking technology

this technology uses catalytic separation technology to separate plant fibers such as rice, wheat and straw in the cooking process, and produce various kinds of paper (corrugated paper, box board paper, packaging paper, etc.) and high-strength fiberboard. After the non fiber parts are treated, plant powder can be obtained to replace grain as feed. In addition to using a small amount of catalyst, no chemical raw materials are added in the production, which greatly saves water than chemical papermaking. The pH value of the discharged water meets the national requirements after being tested by the relevant environmental protection departments

development and application of natural green packaging materials

natural plant fibers (straw, wheat straw, cotton straw, bran shell, etc.) can be used as fast-food boxes. In addition, they can also be rolled or woven into convenience bags. Some natural plant fibers are long and strong, making it easier to weave straw bags. Prices of bamboo and natural irrigation: everyone hopes to buy the most satisfactory products at the lowest price. Wood and wicker fibers can also be woven into baskets Baskets and other packaging containers can be made into natural bamboo tubes to hold fruits, vegetables, tea, etc. bamboo paper packaging boxes can be used as transportation packaging of machinery, electrical appliances and other equipment

natural mineral materials, clay and ceramics can be made into wine, tea and other packaging. Rock particles can be extruded into perlite with light specific gravity. After adding a little adhesive, they can be molded into buffer packaging with different shapes
