News • Pharmaceutical & Medical Packaging News September/October 2015 16 IC Optix conducted the survey, which included the responses of 125 people. Rittenburg believes that con- veniently placed vision aids could help vision-impaired consumers, and in the survey his company found that 75% of respondents would use a magnifier if included with a product. Rittenburg tells PMP News that his company has patented a new type of label technology integrating a magni- fier lens, and there are some product security benefits, too. "Our technology provides a very unique combination of user functional- ity and product security that provides a value-add feature to the consumer/ patient and that also allows them to get involved in the authentication pro- cess," he explains. The layer featuring the lens can be peeled up to magnify the label, allow- ing patients to read small text, and then reapplied for multiple uses. Fixed or variable information can be printed anywhere on the lens film (topside or underside) or on the label layer beneath the lens film, Rittenburg says. "We are using a standard poly- ester label material (PET) for the lens, which is ink receptive," he says. "The materials for the magnifier label (e.g., film, lacquers, adhesives, etc.) are the same materials that are normally used for label production. Therefore, there are no new materi- als or chemistries being introduced into the process." The magnifier film features the same properties of a typical label sub- strate and can be used on rounded bottles surfaces. "For most applica- tions, a 50-micron thickness would be used, but the lens can be provided on any of the typical film thickness (e.g., 25 µm, 50 µm, 75 µm, etc.)," he explains. "We have found that the 50-µm thickness has the flexibility to wrap on curved surfaces but is stiff enough to easily hold and use as a magnifier once it is peeled from the surface of the label." For cartons, the technology can be provided as a transparent label that can be applied as an over-label, Rittenburg says. "The transpar- ent magnifier label can be placed on cartons or any other packaging that does not normally have a label. The transparent over-label will not obscure any existing text or graphics, and it will provide a peelable magnifier that can be removed and used to read any information on the package, insert, etc.," he explains. "This approach can also be used if a company does not want to make any changes to its pri- mary label and would prefer to simply over-label it with a transparent magni- fier label." In addition to integrating thin-film magnifier, IC Optix's technology can carry "a variety of additional overt and covert microstructures into the magni- fier film, which truly make it a security feature as well as a consumer feature," Rittenburg says. Shown in the pictures on page 14 is a tamper-evident label with a printed lens layer that was developed togeth- er with Securikett, an Austrian label manufacturer that IC Optix has part- nered with. The pictures also illustrate an example of a self-authenticating label in which the micro text on the bottom layer can be read using the lens on the top layer. "The lock-and-key feature of a label having microtext as well as the lens to read the microtext provides a new type of self-authenticating label," he says. "The lens areas on this label are the open circle at the top (provides about 3x magnification) and the smaller clear circle within the C at the bottom part of the label (provides about 6x mag- nifications). Also seen are some of the other difractive microstructures in the top left, top right, of the label." IC Optix ofers "the option of either supplying the completely finished label or providing the magnifier film to the brand owner's label converter for incorporation into finished labels," he continues. "We believe the option for both avenues is important. My experience has been that most large brand own- ers have an established supply base of qualified label converters that they may be reluctant to change because it can be a time consuming and tedious process. Also, if the brand owner just wants to add a magni- fier layer to their current label, then using their current label supplier may be the least expensive and most expedient way to go. For those appli- cations, we can supply the lenses (with any associated microstructures) in roll form, with or without registra- tion, and customized to be compati- ble with their label requirements and manufacturing equipment. Think of the rolls of lenses as comparable to rolls of holographic film that get con- verted into finished labels." IC Optix, along with its partner Securikett, can also supply "a com- pletely finished label, customized to a brand owner's requirements, if that is their preference or if their existing label supplier does not have the capa- bility to produce multilayered labels," he says. The company suggests that build- ing a magnifier lens into a product label could increase a brand's purchase appeal. According to IC Optix's sur- vey, 59% of respondents were more likely to choose the product ofering a magnifier device over a similar prod- uct without such a device if all other factors were equivalent. (Survey results can be found in the full report con- ducted by the company.) — Daphne Allen IC Optix suggests that building a magnifer lens into a product label could increase a brand's purchase appeal.
