Compared to aluminum cans, the space for saving steel cans is not very large, and the advantage of paper cans instead of aluminum cans is very obvious. Paper cans cost only about 20% of aluminum cans, can be produced in small batches, and also suitable for small and medium enterprises.
The engineering and technical personnel of the Beijing Institute of Advanced Technology Research successfully developed the first paper can production line equipment in China. The paper cans production line is based on cheap grass pulp as the main raw material, similar to the principle of alloys, with appropriate auxiliary materials made of slurry, through the selection of different molds, die-casting in the die-casting line. This article comes from China's largest can trade After the website of China Packaging Bottles Co., Ltd., it is dried and shaped, and then it is finished and coated to form a readily degradable paper can. Its strength, hardness, toughness are very good, superior performance. This technology has been granted a number of national patents and has been strictly examined by the national technical supervision and inspection department, which is considered a revolution in the fields of environmental protection and materials.
In Shangzhi City, Heilongjiang Province, the use of abandoned straw resources in rural areas has led to the development of paper cans made from straw pulp. They have passed the quality supervision and inspection of packaging products in China in terms of pressure resistance, leakage, falling, sealing, and aluminum cap separation. The test of the center has successfully passed the beer filling test. This project can produce 720 million cans of paper cans.
Paper cans are not much different from aluminum cans in terms of appearance and use, but their excellent properties have injected new vitality into the can market. Experts expect that the annual demand for Chinese paper cans will gradually reach 15 billion, and the development prospects are broad.
