What is a Vacuum Sealer Used for?

A vacuum sealer is a device used to remove air from packaging and create a vacuum-sealed environment.

Vacuum sealers are commonly used for food preservation as well as for packaging purposes in various industries.

Vacuum sealing helps extend the shelf life of perishable items, prevents frostbite, and preserves the freshness of the contents.

What are the common functions of the vacuum sealing machine?

1. Vacuum seal

The main function of a vacuum sealer is to remove air from the package and create an airtight seal.

Vacuum sealers use a combination of vacuum and heat sealing to achieve this.

2. Adjustable vacuum setting

Vacuum sealers often have adjustable vacuum settings to accommodate different types of products.

This allows you to control the vacuum level according to the specific requirements of the item being sealed. Some machines also have a manual seal option that seals bags without a vacuum.

3. Sealing function only

In addition to vacuum sealing, many machines have a sealing-only function. This feature allows you to seal bags or sachets without excluding air, which is great for sealing delicate or fragile items that might be crushed by the vacuum process.

4. Various sealing options

Vacuum sealers are available with different sealing options such as single or double seals. Double seal provides an extra layer of protection and ensures a more secure seal.

5. Built-in bag cutter and roll storage

A built-in bag cutter makes it easy to customize the size of the bag to your needs.

The roll storage unit is used to store rolls of vacuum-sealed bags or sachets.

6. Wet and dry food settings

To accommodate different types of food, many vacuum sealers have settings designed specifically for sealing wet or dry foods.

The humidity setting adjusts the sealing time and pressure to prevent liquid from being drawn out during the vacuuming process.

7. External vacuuming

Some vacuum sealers have an external vacuum feature that allows you to vacuum seal containers or jars with compatible accessories. This extends the machine's versatility beyond just sealing bags.

Summarize

So when you choose a vacuum sealing machine, you can consider factors such as expected use, price range, frequency of use, sealing ability and available functions to choose a vacuum sealing machine that suits your specific needs.
