The inner side of the casserole has a stainless steel body with insulation between the plastic and steel walls.
 Steel is non-toxic and easy to clean. Insulation ensures that food stays hot together. Stainless steel has no odor which helps food retain its original aroma and flavour. 
Since the material is resistant to corrosion and rust, it is safe, durable and effective in storing your foods for longer periods of time.
