Which label stock is best for oil-based products?

If the product is oil or water-based or will be used in a damp environment (like in the shower or bathroom), the best material to choose would be one of the vinyl options or the clear gloss label. These are all made of plastic and will not break down or rub off if in contact with moisture, or be affected by oily products the way that the paper label stocks could. For additional strength and protection, lamination or UV coating can be added after printing to seal the surface.
