How Vacuum Packing Machine Works?

Publish Time:2024-02-20 14:13Author:Visit:323

Vacuum packaging machines work by removing air from a package or container and sealing it to create a vacuum seal.

Here's a step-by-step explanation of how it usually works:


1. Prepare

Place items to be vacuum packed in a dedicated vacuum bag or container.

The bag is usually made of a flexible, airtight material such as polyethylene or nylon.


2. Seal

Place the open end of the bag over the seal strip of the vacuum packaging machine.

A vacuum packaging machine then uses heat to seal the bag, creating an airtight seal.


3. Vacuuming

After the bag is sealed, the machine starts the vacuuming process. The vacuum packaging machine uses a vacuum pump to draw the air out of the bag, creating a vacuum environment inside.


4. Seal (again)

After most of the air is removed, the vacuum packaging machine automatically switches to the sealing function.

The vacuum packer seals the bag again, this time creating a double seal to ensure the vacuum is maintained.


5. release

The vacuum packer releases the bag from the seal and the vacuum-packed item is ready for storage or shipping.


What are the advantages of vacuum packaging machines?

(2) Preserve the flavor of food

Vacuum packaging also helps preserve the freshness, flavor and texture of food.
