Plastic zip seal bags allow aroma and taste to escape and shorten the flavor life of your herbs and spices. We package our herbs and spices in food grade pet plastic jars. These clear, dense jars allow you to see your herbs and spices while still sealing in all the aroma and flavor so you get maximum life from your ingredients.
