1. Food vacuum packaging machines. This type of vacuum packaging machine requires temperature control before vacuum sealing. The equipment comes with a cooling system, making it ideal for applications with high freshness requirements.

2. Medical vacuum packaging machines. These machines should feature a vacuum extraction method that allows products to be stored for extended periods. Since medical vacuum packaging machines are used in high-standard environments such as dust-free and sterile workshops, they can also be applied to food packaging requiring sterility for optimal results.

3. Vacuum packaging machines for electronic products. Using vacuum packaging for electronic products helps protect internal metal components from moisture and oxidation discoloration.

4. Tea vacuum packaging machines. This is an all-in-one machine that integrates weighing, outer packaging, and inner packaging. The advent of tea vacuum packaging machines marks a significant advancement in domestic tea packaging, truly achieving standardization in tea packaging.

a) Packaging speed. To improve production efficiency, dual-chamber or multi-chamber vacuum packaging machines can be selected to accelerate the overall production process.

b) Whether the packaged items require filling with other protective gases. A multifunctional vacuum packaging machine with a gas-filling device can be chosen.

c) Vacuum level requirements for the packaged items. If the items need to be preserved under high vacuum conditions, a chamber vacuum packaging machine should be selected.

d) Requirements of the vacuum packaging machine based on the composition and state of the packaged items.
