Which materials are not suitable for packaging of external vacuum packaging machines

Although the external vacuum packaging machine is a widely used vacuum packaging machine. However, considering its work performance, processing capacity and other factors, it is not suitable for vacuum packaging processing of all materials. For example, the following categories. The size of the packaging bag is too small. This is because the external vacuum packaging machine is vacuumed, and the air nozzle is inserted into the packaging bag, although the action is completed in an instant. However, a small amount of gas will still flow in when the action is executed, which will affect the vacuuming effect. Therefore, once the size of the packaging bag is too small (for example, the sealing end is less than 10CM), the corresponding vacuum packaging effect will be poor. For the packaging of smaller size materials, we recommend that you choose our company's small vacuum packaging machine or double chamber vacuum packaging machine. If the liquid content is too high, we generally do not recommend that you use an external vacuum packaging machine for vacuum packaging of materials with too high liquid content. This is also because the machine is vacuumed through the air nozzle, so once the liquid content is too high, it may cause the liquid to be drawn into the vacuum pump through the air nozzle and the vacuum tube, which will affect the working efficiency of the vacuum pump. Cause damage to the vacuum pump. For powder materials, when a traditional external vacuum packaging machine (without filter) is used for vacuum packaging of powder materials, it will also cause the powder to flow into the vacuum pump with the nozzle and pipe, which will affect the efficiency of the vacuum pump and cause the vacuum pump. Damaged, for the vacuum packaging of powder materials, we recommend that you choose the powder vacuum packaging machine. Materials packed in textured bags will still have gaps after being stacked, so when vacuuming and sealing them with an external vacuum packaging machine. It may cause unclean and incomplete suction, which will affect the effect of vacuum-sealing packaging. If it is the packaging material of the textured bag, you can use the internal pumping vacuum packaging machine to process it. Materials that cannot be placed horizontally The traditional external pumping vacuum packaging machine cannot vacuum-pack materials that cannot be placed horizontally, such as pure bodies or materials with a large volume and a large weight. For such materials, we recommend that you choose a vertical external vacuum packaging machine, or a vacuum packaging machine that can tilt or place the materials vertically.

In the office, various are considered essential since they are used to achieve particular tasks in the office. Among these , automatic packaging machinery, flexo machine manufacturer, and packing machine factory are widely used.
