Resealable bags have a number of applications ranging from food storage, small parts, manufacturing, electronics and many others.

1. Measure Length (L) from the bottom of the bag to the base of the reclosable seal.
2. Measure Width (W) of the bag from side to side.
3. For rigid items, add ½” to the Width (W) of the bag to allow the item to fit through the opening.
4. For thick or bulky items adjust dimensions accordingly.
