Disclosed are polyester shrink films comprising a voiding agent dispersed within a continuous polyester phase. The voiding agent comprises at least one first polymer and at least one second polymer, in which the polymer components have selected physical properties such as glass transition temperature, melting point, tensile modulus, surface tension, and melt viscosity. The resulting shrink films have high opacity, a low coefficient of friction, lower density, low shrink force, and good printability. The films are useful for sleeve label and other shrink film applications, and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations. Also disclosed is a process for separating a void-containing polyester from a mixture of polymers.

The present invention relates to identification documents and smart cards. In one implementation, we provide a smart identification document including a document core. The document core is printed and laminated. The laminated core is milled to create a cavity. An integrated circuitry module is provided in the cavity. In one implementation, the cavity includes an upper cavity and a lower cavity. A laminate layer houses the upper cavity while the lower cavity extends into the document core. The upper cavity's aperture exceeds the aperture of the lower cavity resulting in a ledge in the laminate layer. A portion of the module may rest on the ledge, while another portion of the module may extend into the lower cavity. In another implementation, we provide a contactless smart card including a multi-layered structure. The structure includes a carrier layer including the smart card electronics. The carrier can be permeable (like a mesh or scrim) so that additional layers may be laminated into or through the carrier layer. A multi-layer structure provides a enhanced durability and helps protect the smart card electronics. In still another implementation, we provide a PET-based identification document. The PET-based document includes favorable durability and earth-friendly characteristics.

A phosphor (photo-luminescent) material based authentication system in which a blend (mixture) of at least two, preferably three or more, phosphor materials are used as a photo-luminescent security marking which is applied to or incorporated within an article/document to be authenticated. Preferably, the phosphor materials are each excitable by “eye safe” excitation radiation comprising visible light of wavelength 380 nm to 780 nm. Moreover, when excited the security marking preferably also emits visible light thereby minimizing any risk of damage to an operator's eye in the event of accidental exposure to the excitation radiation and/or light generated by the photo-luminescent marking. The authenticity of the article/document can be authenticated by verification of the composition of the phosphor by exciting the marking and comparing one or more selected parameters of light emitted by the security marking with corresponding parameters of the characteristic emission spectrum of the authentic phosphor blend.

Layers of colored polymers are applied to a surface of a card and are hardened and adhered to a card via light such as ultraviolet or light having a wavelength in the blue spectrum. The layers may be applied to form three dimensional indicia on the surface of the card. For example, letters, numbers, logos, and other indicia (e.g., pictures) may be printed three dimensionally onto the surface of the card. Troughs may be formed via such layering such that indicia is provided as indentations into the added layers. Extensions may be formed via such layering such that indicia is provided as extensions from the added layers. Indicia may be provided via extensions and/or indentations. As such, embossed and/or engraved indicia may be provided on the surface of a card without impacting the structural integrity of the card.

The laminate film may further have additional layers such as a heat sealable layer disposed on one side of the core layer including an amorphous polylactic acid resin and/or a polylactic acid resin-containing layer disposed on the side of the core layer opposite the heat sealable layer, a metal layer, or combinations thereof.

A method of fabricating a tag includes the steps of applying a first patterned adhesive to the surface of the substrate and applying a first electrically conductive foil to the first patterned adhesive. A portion of the first electrically conductive foil not adhered to the first patterned adhesive is removed and a second patterned adhesive is applied to a portion of a surface area of the tag. A preformed second electrically conductive foil is applied to the second patterned adhesive to adhere the second electrically conductive foil to the surface of the substrate and portions of the first and second electrically conductive foils are electrically coupled to each other to form a tag circuit. A second patterned adhesive can be disposed between the first and second electrically conductive foils.

A polyester laminate for an identification document is formed from different polyester materials. One of the polyester materials, such as PCTA, provides a durability property. Another of the polyester materials, such as PETG, provides a layer having a surface with a bonding property for bonding directly to a core without adhesive. The polyester material with the bonding property is selected to enable direct bonding to a printed core layer of TESLIN or polyester through a roll to roll or platen press process.

A biaxially oriented multilayer film comprising a skin layer of polyhydroxyalkanoate, a core layer of polylactic acid polymer and a sealant layer with a metal deposited upon one surface of the skin layer of polyhydroxyalkanoate polymer.

A process of making an improved sheet/card laminate for packaging, signage, displays, transaction cards, ID cards and the like. The process comprises registering flat sheets to a film and then laminating the film or transferring coating(s) from the film to the individual, generally flat sheets via an adhesive. The film or coating(s) may include layered security, functional and/or decorative features.

A multilayer film including a first layer including a polylactic acid polymer, a second layer of a metal primer, deposited upon one surface of the first polylactic acid polymer layer, and a third metal layer deposited on the second metal primer layer. This metal-primed and metallized polylactic acid film exhibits improved moisture barrier properties versus a non-metal-primed and metallized polylactic acid film and can be used as part of a lamination structure for food packaging applications.

A multilayer film having two or more separable adjacent layers. The multilayer film includes adjacent layers formed of compositions of dissimilar primary materials. Optionally, at least one of the layers contains a slip additive to change the release tension between adjacent layers. The multilayer film may include an adhesive layer between layers, with the adhesive layer more adhesion compatible with one of the layers than the other. The multilayer film may be a relatively inexpensive means to produce labels, films, sheets, containers, etc., requiring protection or isolation of one surface without the additional processes of gluing together individual dissimilar layers. Applications include, but are not limited to, the multilayer film being used as a seal to secure containers, including envelopes, and being imprinted and used as a multilayer labeling system. In one preferred embodiment, at least one layer of the multilayer film undergoes a visibly observable change when the at least one layer is released from at least one other layer; the visibly observable change is useful for many purposes, including, but not limited to, serving as a security mechanism within a container seal which, when the seal is broken, provides evidence that the container was opened.

A card formed in accordance with the invention includes a first assembly comprised of multiple plastic layers attached via an adhesive to a metal layer. The multiple plastic layers forming the first assembly are laminated under a first selected temperature and pressure conditions to preshrink the multiple plastic layers, stress relieve the first assembly and render the first assembly dimensionally stable. The laminated first assembly is then attached to a metal layer via an adhesive layer to form a second assembly which is then laminated at a temperature below the first selected temperature to form a card which is not subjected to warpage and delamination.
