Abstract: A packaging film including one or more layers of biaxially oriented polypropylene film and an antiblocking agent. The type and amount of antiblocking agent can be tailored such that the film does not visibly scratch an item in contact with the film during normal distribution and handling. For example, the film can be tailored to reduce or eliminate scratches on a polycarbonate polymer surface. In some embodiments, the film is clear and transparent and has a crinkly texture. One or both sides of the film can also be heat sealable. Additional additives or surface treatments can be used to achieve desired effects.
