Abstract
A laminated, adhesive backing material for application to the rear surface of mirrors to prevent shattering thereof. The backing material of this invention is a three layer laminate which includes a central reinforcing layer sandwiched between two outer layers. The central reinforcing layer typically includes a polyester scrim, while the two outer layers typically are formed of polypropylene. An adhesive layer is provided on the outer surface of one of the outer layers of the laminate. The backing of this invention exceeds a 400 foot/pound test requirement. This backing material is manufactured by heat sealing the central reinforcing layer between the two outer layers and thereafter applying the adhesive to the outer surface of one of the outer layers.
