It is then placed in a sterile package and sealed, protecting it from light and air. There are no chemicals or preservatives used in the process. Milk can be stored at room temperature, but must be refrigerated once opened. Beverage Type: Milk; Flavor: Whole Milk; Packing Type: Tetra Resealable Bottle; Capacity (Volume): 32 oz.
