Plastic bag clip sealer is a very simple yet useful tool that you need it daily to seal plastic bags. It locks the opening of the part you tore off and seal it so that it is completely air tight to prevent leakage. This is particularly important for food such as biscuits or potato chips, because leaving it open will make it lose its crunchiness and eventually turn soggy.
Bag clipper serve as an alternative to seal a bag air tight. It helps preventing moisture from getting into the food. Although it is not as securely tight as sealing the bag completely using heat, it can be re-opened and closed again many time with ease, making it very handy to use on daily basis.
