Abstract: An opaque plastic yard sign is formed from translucent outer layers that carry the indicia of the sign. Between the translucent outer layers is an opaque inner layer which is bonded to the two outer sides by lateral seals, and bonded to one of the outer layers by a horizontal bottom heat seal, leaving an opening for insertion of a wire frame. Preferably the liner includes an upper flap to provide added strength and rigidity to the upper portion of the sign. This reduces the overall cost of the sign while at the same time preventing light transmission from one side through the other without the need of coextruded films.
