    Achieve Consistent Color Of PET Bottles With Color Testers

    The color is the essential property which significantly affects the buying behavior of the customers and help to change the perception of the customers. Many Beverages and pharmaceutical companies understand the importance of colors and try their best to ensure the color of their PET (Polyethylene terephthalate) bottles must remain consistent and accurate every time. To maintain the color harmony of the PET bottles, manufacturers make use of measuring technologies such as color testers throughout their process of manufacturing to ensure the quality and color consistency of the products. To ensure the color quality of the products, it is necessary to test the colors of plastic pellets or granules first. This is done necessarily in the PET & Preform production houses to ensure the color value of the pellets within the acceptable range.

    Purpose of Using TP 60CP Color Tester in PET Industry

    The instrument is used to ensure the color values of the products using the transmittance or reflectance measurement curves according to the nature of the samples i.e. opaqueness, transparency or translucency. For example, the opaque closures or caps of PET bottles and the textures top surface of the closures are measured using the reflectance mode of the instruments where are the transparent or translucent part of the bottles is measured efficiently using the transmittance mode of the devices.
