The current situation and development of China's pharmaceutical paper bucket Market (I)

normal> the packaging of bulk drug powder in China's pharmaceutical industry is almost all in paper buckets. When packaging, different volumes can be selected according to the different varieties of pharmaceutical intermediate powder and lined with plastic packaging bags, so as to facilitate weighing and transportation. Compared with steel drums, paper drums have the advantages of anti-static, light weight, easy recycling, short processing cycle and low cost, and are widely welcomed by all kinds of pharmaceutical factories because of their high strength, elasticity and no pollution. It is not only used in the field of pharmaceutical packaging, but also widely used in the fields of chemical industry, grain, local products, hardware, minerals, building materials, electromechanical and military supplies

current situation of paper bucket production

at present, there are more than 500 paper bucket manufacturers in China, covering more than 20 provinces and cities across the country. The paper buckets produced are generally divided into two types. The first type is full paper bucket, which has cylindrical and square appearance at the beginning. The material used is high-strength cardboard paper, which is processed on a special bucket forming machine. Most of the materials used in the bucket itself are paper fibers and wood fibers, so it is easy to recycle and reuse. In case of emergency treatment, it can be burned and will not produce toxic gas. Therefore, the raw materials of the whole paper bucket, the whole process of production process and waste disposal will not pollute the environment. Therefore, when it is exported as a product packaging, it is widely recognized by foreign merchants and is a product to be vigorously developed in the future. The second type of paper bucket is different from the whole paper bucket in that the upper opening and lower bottom of the circular paper bucket are reinforced with iron sheet, and the upper cover and lower bottom of the paper bucket are made of iron sheet or five ply wood board. Under the same volume, the structure of the paper bucket reinforced by iron sheet is higher in strength and weight than the whole paper bucket. When choosing to hold items, this kind of paper bucket is used when the bucket contains items with a large volume and a weight of more than 30 kg

because the structure of the currently used paper bucket is multi-layer paperboard composite, and the process is made by spiral winding method, of course, the selected paperboard material is the key to determine the production quality of the paper bucket. At present, the quantity of paperboard selected by domestic barrel factories is about g/m2. In order to ensure the strength and rigidity of the barrel, the ring pressure strength of the general raw material paperboard is 300 g/m2, and the bursting index is not less than 3.0KPa? M2/g, the horizontal folding resistance shall not be less than 50 times, and the moisture content shall not be greater than 10%. The strength and quality analysis of the second kind of paper barrels produced in China at present is not only related to the raw materials used, but also related to the thickness of the paper barrels and the size of the axial force acting on the paper barrels. When the material is determined and the perimeter is certain, the vertical pressure strength of the paper barrel should be greater than 8000n, the lateral pressure strength should be greater than 4000N, and the puncture strength should be greater than 10J. At present, the quality of the paper barrel depends on the deformation and strength of the paper barrel. The deformation of the paper barrel is directly proportional to the side pressure and the circumference of the circle when the hanging East workbench moves downward, and inversely proportional to the elastic modulus of the paper barrel, the thickness and the number of layers of the paper barrel. In other words, the greater the lateral pressure acting on the paper bucket and the longer the circumference of the circle, the greater the deformation of the paper bucket. The higher the elastic modulus of the paper bucket is, and the smaller the deformation is when the number of layers and thickness are large. Therefore, it is concluded that in order to improve the strength of the paper bucket in the production of paper bucket, it is necessary to increase the number of layers of the paper bucket and the thickness of the cardboard. When selecting raw materials, paperboard materials with high elastic modulus should be selected. The structure with many paper thickness or layers and the diameter of paper barrel should be of good quality

development trend of paper bucket shape and structure

at present, the shape and structure of paper bucket in China is still relatively single, most of which are round structure forms. The national packaging container paper bucket standard is also a single round paper bucket model. Judging from the development of developed countries, paper barrels show changes in various structural forms, and are developing in the direction of easier stacking and space saving. The economy of paper bucket packaging is the general trend of packaging. After calculation, the volume of cylindrical paper bucket accounting for the same size of transportation tray is about one quarter smaller than that of square paper bucket, that is, one quarter less content. For circular paper barrels mainly used for storage and transportation, square barrels are much more economical than circular barrels, not to mention rectangular barrels are easier to highlight the characteristics of beauty and elegance. At present, square paper barrels have been put into the market, which will become the development trend in the future

how to enhance the competitiveness of paper bucket enterprises

at present, small enterprises in China's paper bucket industry account for the majority, and their competitiveness is poor. It also needs a process to have a big development. In order to increase the competitiveness of enterprises and make them develop rapidly in technology, economy and other aspects, it is necessary to develop from small-scale production to large-scale base production. At present, these parts can replace the metal parts in vehicles in China. There are many powerful production enterprises, which are in line with international standards and have passed the quality certification, marking that China's quality control technology has made a breakthrough development. The establishment of the quality assurance system provides a strong guarantee for the improvement of the quality of paper barrels, and also makes the paper barrels reach a higher level in production, technology, service and other aspects

therefore, for small and medium-sized paper bucket enterprises, it is necessary to establish various technical quality management systems and carry out effective control. Specifically, the enterprise should establish the management system of the whole production process, including raw material procurement system, key process control system, incoming inspection system, workpiece inspection system, operator self inspection system, process mutual inspection system, quality inspector inspection system, finished product inspection system, etc., and should establish the control procedures of the management system. Process quality control should be carried out for the whole production process. First, the process operation procedures and inspection standards of each process in the production process should be formulated, the key processes affecting product quality should be established, and continuous supervision should be carried out to ensure that the loading control of the electro-hydraulic proportional valve ensures that all processes in the product process are under control, and the control status of the production process should be effectively reviewed regularly, and corrective measures should be taken in time, Deal with abnormal situations and problems, and make assessment records. The enterprise should establish the inspection system of raw materials and finished products, formulate the inspection system of raw materials, and record the inspection conditions. The readiness and precision of the testing equipment should meet the inspection requirements, and check regularly. The process inspection includes first inspection, self inspection, mutual inspection, patrol inspection, and has clear records. (to be continued)
