Abstract
A weighted and holographic plastic spinner blade comprises a plastic elliptical-shaped spinner blade having a body formed in plastic injection molding and, integral to the body, a printed label on a first side of body and a weight at an aft end of body. An ink or foil is hot stamped at a second side of the body to create a holographic image that is visible through the body and printed label, forming visual fish attractant properties. Method of manufacture includes: providing an elliptical-shaped mold; positioning a partially transparent printed label on a first side of mold; positioning a weight member in an aft end of the mold; injecting a polymer composition into the mold to form body; hot stamping foil on second side of the body, the ink or foil forming a holographic image; the holographic image visible through the at least partially transparent printed label and body.
