Using a vacuum sealer is an efficient way to preserve food by removing air from the container, thereby preventing the growth of bacteria and other microorganisms. This method is not only useful for food storage but also for keeping other items dry and secure. However, the effectiveness of a vacuum sealer largely depends on the type of bag used. Not all plastic bags are created equal, and using the wrong type can lead to inefficient sealing, wasted time, and potentially contaminated food. In this article, we will delve into the world of vacuum sealing, exploring the types of plastic bags that are compatible with vacuum sealers and those that should be avoided.
Understanding Vacuum Sealing
Vacuum sealing works by removing the air from a plastic bag or container, creating a vacuum that prevents the growth of bacteria, mold, and other microorganisms. This process can significantly extend the shelf life of food and keep it fresh for a longer period. The vacuum sealer itself is a device that applies pressure to the bag, forcing out the air, and then seals the bag to prevent air from re-entering.
Types of Vacuum Sealers
There are two primary types of vacuum sealers: external and chamber vacuum sealers. External vacuum sealers are the most common type and work by placing the bag outside the sealer, with the sealer removing air from the bag through a port. Chamber vacuum sealers, on the other hand, place the bag inside a chamber, and the air is removed from the chamber, creating a vacuum around the bag before it is sealed. Each type of sealer has its own set of compatible bags, and understanding these differences is crucial for effective use.
Importance of the Right Bag
The plastic bag used with a vacuum sealer is an integral part of the process. The bag must be able to withstand the pressure applied by the sealer and maintain the vacuum after sealing. Not all plastic bags are suitable for vacuum sealing.
