What are vacuum bags?
Vacuum bags come with three enclosed sides and commonly made from biaxially oriented polypropylene, biaxially oriented nylon, or multi-ply polyester film. Vacuum bags are specifically designed for reduced air permeability to hold and maintain a vacuum seal.
Vacuum bag packaging is the most common form of vacuum packaging. Vacuum bags are used in homes and high volume commercial packaging facilities. Vacuum bags are available in multiple sizes, thicknesses, and types to accommodate a variety of products.
The most common vacuum bag thickness is a 3 mil thickness or 3 thousandth of an inch. The 3 Mil thickness is thick enough to obtain a dependable seal for long term storage. Larger products with sharp edges and jagged corners commonly use a 4 mil bag thickness or higher.
The type of vacuum sealer being used often determines the type of vacuum bag. Home-use vacuum sealers often require channeled vacuum bags due to low vacuum pressure. Channeled vacuum bags are textured with small dimples to allow air to escape the bag. Channeled vacuum bags lack the clarity smooth bags do, but provide and excellent vacuum.
See below for descriptions of each type of vacuum bag and a vacuum bag chart to help determine the right type of bag needed.
Standard vacuum bags are smooth and available in multiple thicknesses and sizes. The most common thickness of vacuum bags is a 3 mil thickness. The 3 mil thickness is ideal for most products unless the product has sharp edges or corners such as bones or pointed metal objects.
Channeled Vacuum Bags
Channeled vacuum bags or embossed vacuum bags are used on most residential use vacuum sealers. The surfaces of the bags are textured. The channeled vacuum bags allow air to escape from the bag easier. Channeled bags are also said to have a higher than usual oxygen barrier. Channeled bags are available in a 3 mil thickness with multiple sizes to choose from.
Vacuum Zipper Bags
Smooth and clear vacuum bags with a zipper for easy opening. The zipper is on one end of the bag and the other end of the bag is open to insert products and create a seal. A common use for vacuum zipper bags is meat packaging. Once the zipper bag is opened by the customer, it can be easily reclosed.
Notched Vacuum Bags
Notched vacuum bags are smooth and clear vacuum bags with an easy to open tear notch. Our notched vacuum bags are available in a standard 3 mil thickness. Sizes of notched vacuum bags range from 4 to 12 inch widths.
