The current situation and development direction of the domestic pharmaceutical paper bucket Market

almost all the bulk drug powders in China's pharmaceutical industry are packaged in paper buckets, which can be selected according to the different varieties of pharmaceutical intermediate powders. This project is a component of the China standard high-speed motor car and high-speed railway key equipment R & D and experimental engineering construction project (approved by the national development and Reform Commission), with different volumes 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 that produce glue for fixing strain gauges are roughly 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, the bursting index is not less than 3.0KPa · m2/g, the horizontal folding resistance is not less than 50 times, and the moisture content is not more 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 of the paper barrel and the circumference of the circle, but inversely proportional to the elastic modulus of the paper barrel, the thickness of the paper barrel and the number of layers. 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 of paper thickness or number of layers and the diameter of paper barrel has better 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. At present, there have been many powerful production enterprises in China, 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 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 each process in the product process is under control, and the control status of the production process should be effectively reviewed regularly, corrective measures should be taken in time, abnormalities and problems should be handled, and assessment records should be made. 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

paper bucket product quality and domestic and foreign standards

with the deepening of China's opening-up policy, more goods are exported overseas. As an outer package, paper buckets also travel across the sea with goods to realize their own value. However, in the process of transportation, there is also the leakage of paper barrels, which is the most serious quality problem of paper barrels, and must cause the height of the enterprise. The leakage of the paper barrel is mainly caused by the heavy load and large deformation of the paper barrel itself during use or handling, resulting in the separation of the barrel body from the barrel bottom, which is mainly manifested in the separation of the bottom of the paper barrel from the joint of plywood or paperboard, resulting in the leakage of items. The main reason is that there are still some problems in the production process, one of which is the material problem. The plywood used has an impact on the product quality, because when the bottom cover of the paper barrel is made of plywood, the thickness of the plywood selected is uneven, and most of the thickness does not meet the requirements. In addition, the bonding strength between plywood layers is low, which is easy to separate from the barrel body, and the dimensional tolerance of plywood cutting is not accurate. Therefore, in the selection of raw materials, plywood materials that meet the standard should be selected, and the cutting size should be strictly controlled within the tolerance range, and quality monitoring should be carried out. The thickness of plywood shall be determined according to the maximum weight of the contents of the paper bucket. When the weight of the contents of the paper bucket is about 50kg, the thickness of the plywood shall not be less than 6mm. The second is the problem of paper barrel production equipment. The connection between the barrel body and the bottom of the barrel in the production process of the barrel mainly depends on the forming process of the bottom seal, so the operation of the equipment forming the bottom seal will affect the overall quality of the barrel. For the operation of the equipment, the size changes of each part of the bottom seal mold should be often checked, because when the mold is closing the bottom of the barrel, the vertical plane of the lock ring mold is easy to deviate, resulting in the uneven combination of the bottom of the barrel, This will affect the coincidence between the barrel bottom and the barrel body

adopting international standards and foreign advanced standards is the technical and economic policy of China's heavy industry and the most effective and economical way of technology introduction

in order to promote the development of paper barrel industry, improve product quality and make the standard level of paper barrel reach the international advanced level, the national standards should meet the international similar standards. In the 1990s, China formulated the national standard gb/t14187 for paper barrels of packaging containers, which absorbed the advanced standards of foreign similar products for paper barrel products, such as the former Soviet Union standard toct13479 "general technical conditions for composite cardboard", and the West German standard din641t1 "packaging materials, fiberboard cover barrels, weather resistant steel bottoms and covers". The above standards mainly focus on specifications, dimensions and requirements for raw materials, but the Soviet Union toct13479 also has performance requirements. However, the products in the standard may be due to their small volume, low strength, falling height of only 200 mm, and the maximum compressive strength of only 1570n. Only the products in the British standard bs1596 "technical specification for fiberboard drums for overseas freight" are closer to our products in terms of structure and capacity. Therefore, the formulation of China's standards mainly refers to the bs1596 standard. According to experts, the manufacturing equipment and technology of fiberboard barrels in Britain today are relatively advanced, and the product quality is relatively good. In order to make the standard level advanced and reasonable, conform to China's national conditions, and meet the use requirements of all aspects, China has appropriately graded the product quality. The index of grade I paper bucket in the national standard is basically consistent with the British standard bs1596, and basically reaches the standard level of international paper bucket. In the national standard of packaging container paper bucket, the stacking performance and drop performance test can best reflect the quality characteristics of paper bucket, and the selected weight of stacking load capacity is 4900n, which is equivalent to the index of British bs1596. The quality performance test method of paper bucket is: place the sample of paper bucket on the stacking ground, place the load plate on the stacking ground, place the load plate in the center of the top surface of the sample, and then without causing impact, Place the weight on the load plate to make it contact the load plate evenly. The error between the total weight of the weight and the load plate and the specified value should be controlled within plus or minus 2%. The stacking load is 4900n, and the 24-hour non leakage, non cracking and permanent deformation shall not affect the stacking capacity of the paper barrel. The stacking test is to simulate the stacking of paper drum packages in the actual storage process. Transportation and stacking requires 3 samples to be stacked with a stacking height of 3 meters. The drop height and method of the drop performance test of the paper bucket adopt the provisions of British bs1596. First, the paper bucket samples are pretreated with temperature and humidity. The temperature and humidity are 20 ± 2 ℃, and the humidity (65 ± 5%) for 48 hours. The bucket is filled with dry sand and sawdust mixture to reach 95% of the specified maximum holding mass and volume, and it is closed. The temperature and humidity of the mixture are consistent with the sample pretreatment conditions. The drop test requires that the number of tests is 6 and the drop height is 0.8m. The pretreated samples are lifted to the predetermined height with the test equipment in the test. After being stabilized, start the drop device so that the sample electrode can continuously monitor its EEG activity and instantly make a free fall movement. Each sample falls once. When falling, first make any point on the bottom edge of each barrel fall to the ground
