This item is part of the ShieldPro 1-Gallon Specialty line.  It is a Tamper Evident bag with a zip seal at the top of the bag.

A Tamper Evident bag is open at the bottom, with a perfect pre-sealed Zip Seal at the top.  It is filled from the bottom of the bag and heat sealed. 

It is made of the trademarked ShieldPro 5 Mil material for the best oxygen, moisture and light protection.  A 1-Gallon bag will hold around 5-7 pounds of dry goods.  Most customers can use a standard household clothes iron (on the wool setting) to seal ShieldPro bags, but folks storing large quantities of food may want to look at our KF-150CST heat sealer for the absolute easiest method of sealing.
