Vacuum Packer Machines

Vacuum packing machines can be used for the vacuum packing of a variety of things such as:

- meat cuts

- food

- computer chips

You need to ensure that the machine you buy is suitable for the product you wish to pack.

First you need to know about the two different vacuum packer chamber sizes which are:

Effective Chamber Size

The effective chamber size is the space between the sealing bar(s), the sides and the lid.

Absolute Chamber Size

The absolute chamber size is the space between the walls of the chamber.

The effective chamber size is what you need to consider as this is the maximum size of product that could be sealed.

You need to make sure you have space for your vacuum packer machine to fit into your production line/kitchen.

This sounds obvious but it is often overlooked and these machines can be surprisingly large so it's important to make sure it will fit in the space you have.

A powder filter is recommended if the machine will be used to pack fine powders. The filter prevents the powder from going into the vacuum pump.

A liquid filter is recommended if the machine will be used to pack liquids. The filter prevents liquids from going into the vacuum pump.

When it is important to obtain an exact vacuum or gas level a sensor control is a must.

A standard vacuum packing machine normally relies on a time cycle for the vacuum and gas levels, which is accurate enough for most applications.

However, when dealing with products that vary in volume or density, a sensor ensures that each package is under the same level of vacuum.

Adding gas to a package is a way of extending the shelf life of a product. The product, and the space around it in the chamber are vacuumed as normal.

Usually after the vacuuming process the bag is sealed; but with gas flush, the pouch is injected with a gas or gas mixture. When the desired volume of gas is reached the bag is then sealed. This gives a very low residual oxygen percentage and the product is no longer under vacuum pressure.

ESD is the rapid transfer of electrostatic charge between two objects.

During the vacuum and decompressing phase, air flows over machine surfaces and builds up a static load. If electrostatic discharge occurs during packaging of an electronic product, the product could be damaged instantly.

With an ESD equipped vacuum packing machine all the surfaces are made of conductive material that discharges electrical current away to the ground connection of the machine.

There will be no static loaded components inside the machine, so the vulnerable electronic products are protected from electronic damage.

To ensure the protection, the products need to be packed in anti-static bags.
