Logistics Packaging Container Technology (1)

4. Bottles.
Bottles are small containers with large differences in bottle neck sizes. They are rigid packages. The packaging materials have high resistance to deformation, and the rigidity and toughness requirements are generally high. Individual bottles are interposed between rigid and flexible materials. The shape of the bottle can be deformed to a certain degree when subjected to external forces. Once the external force is removed, the bottle shape can be restored. Bottle structure is bottleneck diameter is much smaller than the bottle, and open at the top of the bottleneck; packaging operation is filling operation, and then close the bottle cap. The packaging volume of the bottles is generally not large, and it is suitable for beautifying decoration, mainly for commercial packaging and internal packaging. The main packaging liquid, powder goods. Bottles can be divided into round bottles, square bottles, high bottles, low bottles, and shaped bottles according to their appearance. Bottle caps and bottle caps are available in threaded, lug, crown, and enveloping styles.
5. Packaging cans (tubes)
The packaging can is a packaging container with roughly the same cross-sectional shape in various parts of the can body, a short neck of the can and a small inner diameter of the can neck which is smaller than the inner neck of the can body, and is a kind of rigid packaging. The packaging material has high strength and the tank has strong anti-deformation ability. The packing operation is a filling operation, and then the tank opening is closed. It can be used as a transport package, an external package, or a commercial package or an internal package. There are three main types of cans (tubes):
(1) Small packaging cans. This is a typical tank, which can be made of metal or non-metal materials. Its capacity is not large. Generally, it is sold and packaged, and the tank can be assembled and beautified in various ways.
(2) Medium-sized packaging cans. The appearance is also a typical tank body with large capacity. It is generally used as a raw material for chemical raw materials and native products, and plays a role in transportation and packaging.
(3) Container tanks. This is a large tank with cylindrical, spherical, ellipsoidal shapes, both horizontal and vertical. Container tanks are often large tanks with small tank necks. They are filled with filling operations, and irrigation operations and discharge operations are often not performed in the same tank. Another unloading export. Container tanks are typical transport packages suitable for packing liquid, powder, and granular cargo.
