Abstract
Thin filmed thermoplastic material wall coverings having a preprinted image thereon and provided with a static electrical charge for securing the coverings to a surface. The wall covering may comprise posters, maps, and the like, and the image is printed on the film by means such as silk-screening. The static electrical charge is sufficient to removably secure the film to a wall surface, a window, or the like, and allows for relocation of the covering without damage to the surface upon which it is secured. The coverings may be packaged individually, or be dispensed from a continuous roll. Preprinted maps adherable to a window surface such as a windshield of an automobile are provided.
Claims15
A wall covering having a preprinted image thereon, comprising a thin film of oriented plastic material having a thickness between 0.1 mm and 1 mm, said film having a static charge imparted thereto for removably securing said covering to a surface by means of static electricity.
A thin plastic film, comprising oriented polypropylene in sheet form having a thickness between 0.01 mm and 1 mm, said film having printing thereon and having a static charge imparted thereto for securing said film to a surface by means of static electricity.
A wall covering which is separable from a continuous web of oriented thin plastic film having a thickness between 0.1 mm and 1 mm, said film having first and second parallel transverse perforations spaced from each other across said web so as to define a length of said covering;
- said web of film having a static electrical charge imparted thereto for securing said covering to a surface by means of static electricity.
A transparent thin film of oriented polypropylene plastic having a thickness between 0.1 mm and 1 mm and having the details of a map printed thereon, said film having a static charge imparted thereto sufficient to secure said film to a window of an automobile.
A method of making a wall covering constituted of a thin film of oriented polypropylene plastic having a thickness between 0.1 mm and 1 mm, comprising the steps of:
- preprinting an image on said film;
- and imparting a static electrical charge on said film;
- such that said charge is sufficiently to secure said covering to a surface such as a wall or a window.
