Lohmann’s proprietary GL-187®—a non-migratory, inert pressure sensitive adhesive—was developed specifically for diagnostic needs and has become the industry standard for assay-based diagnostic testing devices. Over the past 25 years, it has been used in more than 8 billion test strips! GL-187® can be laminated to various rigid plastic films needed for diagnostic tests including PVC (vinyl), polyester, and polystyrene as well as custom materials and laminates, and is easily die-cut. Typical applications include backing cards and rolls and cover tapes—either printed or unprinted.
