Film labels can be made from PET, polyester or polypropylene. Filmic material is very flexible and good for unusual, curved wine bottle shapes. There are different types of film materials, some better for indoor use (for example, Acetate), and some suitable for harsher conditions (Polyester). Clear film or “no label look” film is becoming very popular, especially for beverages that want to emphasize the element of freshness, purity and/or elegance.
