Polyester Film May Simplify Label Converting Process
A manufacturer of polyester and polypropylene films has developed a coextruded polyester label film that prevents migration of silicone to other surfaces. The PET Lumirror PS10 film, developed by Toray Plastics Inc. (North Kingstown, RI, USA) allows label converters to sidestep the need for corona treatment or chemical priming processes.
Corona treatment is typically applied to both sides of a film, which isn’t necessary in some applications. It can even be detrimental, depending on subsequent processing steps. The new label film eliminates issues related to hazardous solvents, volatile organic compounds, and special venting equipment because it does not need to be chemically primed.
The coextrusion comprises a thin layer of amorphous material over a thicker layer of crystalline polyester. The film resists abrasion and features thermal, dimensional, and cure stability. Applications include permanent or semipermanent labels attached to medical devices and release liners for medical tapes and bandages.
“Label converters who must meet stringent silicone bonding requirements, or who seek entry into profitable label markets, can gain significant production and economic advantages with this [technology],” predicts Steve Sargeant, new business development manager for Toray.
