Width dimension is the flat measurement - Not the diameter.
You are looking at prime, clear, 1.5 mil LDPE plastic tubing. This thickness is good for light applications where the primary function is protection from dirt or moisture.
This is premium, FDA/USDA approved, heat sealable poly tubing which is an excellent alternative to bags. It works for varied length items, as you can cut it to your required length and either tie it or seal it to suit the size prior to storage, or for keeping your items clean and protected from moisture during shipping.
Rolled onto 3 inch cores, you will find this packaging to be convenient for mounting on a wall or table rack. Please contact us for discount pricing of larger quantities.
