The aim of the invention is to create polymer films, especially single-layer films, coextrusion films, or laminated films, which are produced or further processed on top of bubble films or flat films, in coating devices and double/bubble installations and can be well processed in a durable manner. Said aim is achieved by providing said polymer films with a matrix polymer, a carrier polymer which is homogeneously spread by means of a lubricant that is bonded therewith, and a quantity of an unbonded lubricant. The proportion of the bonded lubricant in the polymer composition represents up to 3 percent by weight while the proportion of the unbonded lubricant in the polymer composition represents approximately 0.5 to 8 percent by weight. |
