Co-Extruded Plastic Film for Use with a Vehicle Seat

摘要

A plastic film for use as a temporary vehicle seat cover to be installed by an automotive manufacturer. The seat cover protects the vehicle's seat from dirt before the vehicle is purchased by a consumer. The plastic film also has minimal acoustic properties so that the vehicle seat does not interfere with routine automotive acoustic testing known as the Buzz, Squeak, and Rattle test. The plastic film also has a high degree of visual clarity to allow a potential consumer to view the vehicle's seat. The plastic film further has a differential of the coefficient of friction on the opposed sides of the film to minimize movement and noise of the film when a driver is in the vehicle.
