In this how to video Robert Hall shows you easy white background lighting methods for product and portrait photography.

White backgrounds can be frustrating and require a lot of effort in post-production if you do not capture them right. For portrait photography, he recommend overexposing a white surface with flash from the sides. Then, use V flats to block any light from coming back into your lens. For products, he recommend a translucent product table so you can light the surface without any shadows.
