Embodiments described herein relate to articles and methods for forming liquid surface films on the interior surfaces of containers for holding one or more products comprising one or more Bingham plastic materials. Bingham plastic materials behave as a solid under no or low shear stress, and behave as viscous liquids when an applied shear stress exceeds a yield stress. In some embodiments, a container for containing a product includes an interior surface and a liquid disposed on the interior surface. Before introduction of a product into a container, the liquid may be surrounded by air. The liquid-air interface in contact with the interior surface makes a contact angle, &#x3b8;, with respect to the interior surface of the container, of about 0&#xb0;. After a product has been introduced to the container, the liquid is at least partially covered by the product. The liquid-product interface in contact with the interior surface, makes a contact angle, &#x3b8;, with respect to the interior surface, of less about 60&#xb0;. The subscript 'o' denotes the liquid, subscript 's' denotes the interior surface, subscript &#x201c;a&#x201d; denotes air, and subscript &#x201c;p&#x201d; denotes a product. In some embodiments, the contact angle &#x3b8;can be less than about 50&#xb0;, less than about 40&#xb0;, or less than about 30&#xb0;.
