摘要： An object is coated with a plastics film by a process in which a preformed solid plastics film is brought into contact with an object, the film is stretched over the object and substantially all the film made to adhere substantially permanently to the object. Thus, a tacky plastics film may be held in a frame and the object pushed through the film. Alternatively the object may be conveyed on a moving belt to a position adjacent to a heated plastics film and the film brought into contact with the object. The plastics film may for example be an ethylene-vinyl acetate copolymer.
