Vacuum packaging is a process in which air is removed from a package and sealed. This process removes the oxygen and slows the spoilage of food. Vacuum packaging also increases the shelf life of food by reducing water vapor transmission.
Vacuum Packaging Machines
There are two types of vacuum packaging machines: chamber and external devices. Chamber machines create a vacuum inside the package itself, while external appliances draw air out of the entire packaging area.
Vacuum packaging has many benefits, including longer shelf life of food, slows dehydration and spoilage of dry goods, prevents freezer burn in frozen foods, highly efficient storage for bulk products (reducing packaging costs), and easier stacking of goods in stores and storage areas.
Vacuum packaging products are unsuitable for long-term storage, but only to make food last longer after opening.The vacuum packaging process involves removing air from a package which can be done through a chamber machine or an external machine. Chamber machines use a pump to clear the air, while external devices use a combination of vacuums and air pressure.Chamber machines can be broken down into two different types: hand-held chamber vacuum packaging machines and chamber vacuum packaging systems. Hand-held chamber vacuum packing machines are intended for one or two packages at a time, while a chamber system is used in production lines to give a continuous flow of packets.
External machines can also be broken down into two different types: table-top external vacuum packaging machines and floor standing external vacuum packaging machines. Table-top devices are smaller and compact, while floor-standing machines have a higher output.
Vacuum packaging is not suitable for long-term storage and should only make food last longer after opening. There are many different types of vacuum packaging machines, each with its benefits and drawbacks. So, before investing in a vacuum packaging machine, research the different types to find the best one for your needs.
