1. Good mechanical performance: compared with other packages, tin cans have much higher strength, good rigidity and are not easy to crack. It can be used not only for small sales package, but also for large transport package.
2. Excellent sealing performance: tinplate cans have superior sealing performance than any other materials. They are resistant to air, moisture, light and taste, and are reliable in sealing, which can protect the product to the maximum extent.
3. Mature process: The production process of tinplate cans appeared very early, its process is quite mature, and its supporting production equipment and tools are also mature, so that the production efficiency can be improved to a greater extent, and the packaging needs of various products can also be met.
4. Fine offset printing: the printing performance of metal materials is far better than that of other materials; Logo, design, text, etc. are very delicate and mellow in printing, which can effectively avoid paint falling and color fading.

The ring cutter set solves the problems of large soil disturbance, low test accuracy, and easy deformation of the ring cutter to some extent, but there are still problems of large shear resistance and slow sampling. The utility model's multi-function combination ring knife not only solves the problems of large soil disturbance, low test accuracy, and easy deformation of the ring knife, but also realizes small shear resistance, quick sampling, and provides soil bulk density, subgrade compaction, and the like. A convenient and quick way. The ring cutter set of the utility model comprises a ring knife shell with an inner ring knife composed of two half-pipes with two convex ends at both ends, and one end of the ring knife shell is connected with a hollow cylindrical knife head. One end of the slope is provided with a slope at the inner and outer walls, and the other end is connected to a base provided with a vent hole. The base of the base is connected to a handle, and the handle is provided with a collar, a connecting rod wire and a load hammer. .
The use of a ring cutter to measure compacted soil compactness, in addition to improving efficiency, also greatly reduces the area of ​​disturbed soil. The results of measurement and analysis show that the area required for the new type of circular knife sampler is basically a constant value, with little change with the detection point, while the area required by the traditional circular knife method for measuring compacted soil compactness is within a certain range. Within the larger changes.
5. Different shapes: tin cans can be made into various shapes according to different needs, such as square cans, oval cans, round cans, horseshoe shaped cans, trapezoidal cans, octagonal cans, etc., which not only meet the packaging needs of different products, but also make the packaging of tin cans more varied.
The Inherent Advantages of Circular Knives in Soil Determination
The application of ring knives in soil bulk density measurement and compaction soil density detection is very common. This is a very classic method. There are certain shortcomings in the method of earth taking with the ring cutter, because of great disturbance in the earth taking process, which destroys the fundamental requirement of collecting the undisturbed soil and makes the test analysis lose its accuracy; the shear resistance is large, sampling is slow, time-consuming and laborious. The efficiency is very low; in the process of earth-fetching, the ring cutter is easily deformed, the soil taking is difficult, and the undisturbed undisturbed soil cannot be collected. The emergence of ring cutters solves this problem.
