First, the packaging bag
The packaging bag is an important technology in flexible packaging. The packaging bag material is a flexible material with high toughness, tensile strength and wear resistance. The general packaging bag structure is a tube-shaped tube structure, one end is sealed in advance, and the other end is sealed after the packaging is completed. The packaging operation generally adopts a filling operation. Packaging bags are widely used in transportation packaging, commercial packaging, interior and exterior, so they are widely used.
Second, the packaging bottle
The bottle is a small container with a large difference in bottleneck size. It is a kind of rigid packaging. The packaging material has high resistance to deformation. The rigidity and toughness requirements are generally high. Individual packaging bottles are between rigid and flexible materials. Although the shape of the bottle can be deformed to some extent when subjected to external force, once the external force is removed, the original bottle shape can still be restored. The structure of the packaging bottle is that the diameter of the bottleneck is much smaller than that of the bottle and is open at the top of the bottleneck; the packaging operation is a filling and filling operation, and then the bottle mouth is closed with a bottle cap. The packaging volume of packaging bottles is generally not large, suitable for beautification and decoration, mainly used for commercial packaging and inner packaging. Mainly package liquid and powder goods. Packaging bottles can be divided into round bottles, square bottles, tall bottles, short bottles, special-shaped bottles, etc. according to their shapes. The sealing methods of bottle mouth and bottle cap are screw type, lug type, crown type, encapsulation type, etc.
Third, packaging cans (tubes)
A packaging can is a kind of packaging container in which the cross-sectional shape of the can body is roughly the same, the can neck is short, and the inner diameter of the can neck is slightly smaller than the inner neck of the can body or there is no can neck, which is a kind of rigid packaging. The packaging material has high strength, and the tank has strong resistance to deformation. The packaging operation is the filling operation, and then the can mouth is closed, which can be used for transportation packaging, outer packaging, and can also be used for commercial packaging and inner packaging.
Fourth, the packaging box
Packaging box is a packaging technology between rigid and flexible packaging. The packaging material has certain flexibility, is not easy to deform, has higher compressive strength, and has higher rigidity than the bagged material. The packaging structure is a cube with a regular geometric shape, which can also be cut into other shapes, such as a round box shape or a sharp corner shape. It generally has a small capacity and has an opening and closing device. The packaging operation generally adopts code loading or filling, and then closes the opening and closing device. The overall strength of the packaging box is not large, and the packaging volume is not large. It is not suitable for transport packaging, suitable for commercial packaging and inner packaging. It is suitable for packaging blocky and various shaped items.
Fifth, packing box
Packaging boxes are an important category in rigid packaging technology. The packaging materials are rigid or semi-rigid materials, which have high strength and are not easily deformed. The packaging structure is the same as the packaging box, but the volume and shape are larger than the packaging box, and the two are usually separated by 10 liters. The packaging operation is mainly to put the code, and then close the opening and closing device or seal one end fixedly. The overall strength of the packaging box is high, the deformation resistance is strong, and the packaging volume is also large. It is suitable for transport packaging and outer packaging. The packaging range is wide, and it is mainly used for solid grocery packaging.
