How effective is vacuum packing?

The vacuum packaging machine can automatically extract the air in the packaging bag and complete the sealing process after reaching a preset vacuum degree. It can also be filled with nitrogen or other mixed gases, and then complete the sealing process. Vacuum packaging machines are often used in the food industry because the food can resist oxidation after vacuum packaging, so as to achieve the purpose of long-term storage. It has the characteristics of a beautiful appearance, compact structure, high efficiency, and easy operation.

Applicable materials and industries

The vacuum packaging machine uses plastic or plastic aluminum foil film as the packaging material to vacuum liquid, solid, powder, paste, grains, fruits, pickles, dried fruits, chemicals, medicinal materials, electronic components, precision instruments, rare metals, etc. Vacuum-packed items can prevent oxidation, mildew, moth-eaten, rot, and moisture, extending the shelf life. It is especially suitable for tea, food, medicine, shops, research institutions, and other industries.

The advantages of vacuum packing machine

  1. Automatic operation

With the development of science and technology, automatic mechanical equipment has emerged, which has realized the measuring, filling and bag making, printing date, and product output in one step.

  • Improving production efficiency

The automatic vacuum packing machine works efficiently, and it can seal several bags together. There are vacuum room packaging machines and stretch film vacuum packing machines. The latter is fully automatic equipment, suitable for mass production.

  • Slowing food spoilage effectively

Vacuum packaging can create a vacuum environment to inhibit microorganism growth. Little air in the vacuum-sealed bags can prevent food from oxidation and slow down food spoilage, extending shelf life.

Selection principles

There are a variety of vacuum packaging machines, and the following factors should be considered when selecting.

  • (1) Packaging speed: For the sake of improving production efficiency, double-chamber or multi-chamber vacuum packaging machines can be used to improve the overall production schedule compared with single chamber vacuum packer.
  • (2) Whether the packaged items need to be filled with other protective gases. You can choose a multifunctional vacuum packaging machine with the inflatable device if you need it.
  • (3) Requirements for the vacuum degree of the packaged items. If the packaged items need to be preserved in a high vacuum condition, you need to choose a vacuum chamber packaging machine.
  • (4) If the working space is small or low budget, desktop vacuum sealer is a good idea. It occupies small space and easy to move.
