These bags are made of a foil-laminate material similar to Mylar but heavier duty. They have a zip-lock type opening on the top and the sides are pressed together and can be trimmed off to make the bag fit better into the chamber. The bottom is folded over. SWP Bags are durable and are designed to be reused many times. They are normally lost in the orchard before they wear out.
These bags are designed for use in Stem Water Potential Readings. For more information about Stem Water Potential and what it means to you, contact us at firstname.lastname@example.org
