Linx Printing Technologies has launched two innovative inks specifically designed to address the challenges of printing consistently high-quality and easily readable codes on the latest generation of flexible films. These advancements are particularly relevant for the food and beverage packaging industry.
The new Linx Black Strong Plastic-Film Ink 1015 and Linx Black Strong Plastic-Film Ink 3415 have been meticulously formulated to meet the global demand for inks that deliver reliable adhesion on plastic film packaging. They are well-suited for a wide range of pack formats, including plastic flow wraps for dry foods, plastic pouches for food sauces, confectionery, and pet foods.
Simon Millett, inks product manager at Linx Printing Technologies, emphasized how recent legislative changes, such as new plastic taxes, along with evolving retailer and consumer demands, are prompting manufacturers to reduce their plastic usage. This trend has resulted in a shift toward stronger laminated plastic films and increased reliance on recycled and recyclable packaging.
“As a result, we are seeing the introduction of thin flexible plastic wrapping and pouches of OPP, BOPP, HDPE, and LDPE, but these can present a challenge for ink adhesion. Many general-purpose inks do not stick effectively to these lower surface energy plastics,” Millett stated, highlighting the issue. “This means that codes may smudge, scratch, or rub off during production or transit, leading to reworking, rejects, and even fines.”
The two new inks excel in providing excellent adhesion while ensuring readability and supporting printer reliability. Notably, both inks are PFAS-free (per- and polyfluoroalkyl substances) and CMR-free (carcinogenic, mutagenic, reprotoxic), adhering to standards like the EuPIA (European Printing Ink Association) Exclusion Policy. Furthermore, Linx Black Strong Plastic-Film Ink 3415 is a non-MEK version.
To guarantee the inks’ suitability for the global market, Linx conducted extensive testing on various packaging formats from regions including Australia, China, France, the UK, India, the Philippines, and Poland.
“Our team of scientists designed and tested over 100 formulations during the development process to ensure we devised a truly versatile solution for the widest variety of pack types and applications,” noted Dr. Amy Ruddlesden, ink development manager and principal chemist at Linx Printing Technologies.
“The new Linx Black Strong Plastic-Film Inks 1015 and 3415 will help customers ensure full traceability for their products by guaranteeing consistent high-quality, easy-to-read codes on today’s flexible plastic packaging.”
