Product focus Linx Thermochromic inks Linx Thermochromic inks are technically advanced inks that undergo a permanent colour change when subjected to certain wet heat conditions, such as the sterilisation processes employed in the food industry. Canned food products need to go through a Vetort' or sterilisation process for health and safety reasons. In addition, the cans need to be coded with batch codes and 'best before' dates as part of the manufacturing process. With their ability to change colour when exposed to wet heat, Linx Thermochromic inks are able to perform a dual role: • Print variable information such as batch • Act as an easily monitored visua indicator that minimum process parameters have been met In addition, these inks meet USDA regulations about incidental contact with Although Linx Thermochromic inks have been developed primarily for product coding in the food canning industry, they also have properties that are beneficia in other industries, such as engineering components, PVC cabling and extruded plastics. These inks show good resistance to solvent and alkalis after colour change (heating), and have the ability to penetrate and then resist removal by oily or waxy Withstand sterilisation Change colour with wet heat Meet USDA requirements Penetrate oily or waxy coatings Excellent adhesion on a wide range Ideal for food canning and industrial THINKING ALONG YOUR LINES
