Abstract: An anti-counterfeit card includes a substrate on which an anti-counterfeit membrane is attached. The substrate includes a sheet of plastic with two transparent surface layers formed on two opposite sides thereof. Printing may be selectively carried out on the two sides of the plastic sheet and the outer surfaces of the surface layers. The anti-counterfeit membrane includes a hologram film on which serration defining a hologram is formed so as to make it difficult to counterfeit the card. A method for manufacturing the anti-counterfeit card is also disclosed. A method for manufacturing the anti-counterfeit card is also disclosed, comprising the steps of providing a substrate; providing an anti-counterfeit membrane which comprises a hologram film; and attaching the anti-counterfeit membrane to the substrate to form the anti-counterfeit card.

Abstract: A multi-layer packaging foil having a hologram membrane therein, includes a bottom structure made of plastic material and a top structure made of aluminum foil with a hologram membrane sandwiched therebetween. The hologram membrane is composed of a layer of resin and a thin layer of aluminum with a serration defining a hologram formed thereon so that when the packaging foil is viewed from the bottom structure side, a 3-D image is generated by the serration. Also provided herein is a method for manufacturing the multi-layer packaging foil, including the steps of applying a resin layer on a plastic bottom structure with a thin layer of aluminum covered thereon, forming a serration defining a hologram on the aluminum and resin layers by means of a serration forming roller and adhesively attaching a top structure which comprises an aluminum foil over the serration.
