An ‘eye mark’ (also known as ‘eye spot’) is a small rectangular printed area located near the edge of the printed flexible packaging material. A sensor on the form-fill-seal (FFS) machine reads the eye mark to identify packaging material, control the material’s position, and coordinate the separation and cutting of the flexible packaging material. To package products with flexible packaging, the printed material is supplied on a continuous roll and fed into the FFS machine where the sensor reads the eye mark to indicate when to cut individual units, fold the material, seal the sides (creating the packaging’s shape), fill with the product, and then seal the final side. It’s important to note that the eye mark pathway should be clear of obstructing design or text to ensure the sensor reads it properly.
