A removable adhesive tape comprising a highly extensible and substantially inelastic backing and a layer of pressure-sensitive adhesive. The backing has a high tensile strength, has a lengthwise elongation at break of at least about 150% with less than about 50% elastic recovery after stretching. The adhesive can be a normally tacky and pressure-sensitive adhesive and is coated on at least one surface of the film backing. The adhesive is preferably highly extensible, does not separate from the backing during stretching, and has higher cohesion than adhesion to any suitable substrate. After being applied to a substrate, the adhesive tape of the present invention becomes firmly bonded, but can be easily removed without damaging the substrate by simply stretching it in a direction substantially parallel, i.e. less than about 35.degree., to the surface of the substrate.
An assembly comprising a container including first and second relatively moveable panels positioned in a closely adjacent closed position to close the container, and being moveable to an open position with said relatively moveable panels spaced apart to open said container, said relatively moveable panels including attached portions having surfaces that are closely adjacent in said closed position;
