    Clariant has teamed up with pigment supplier Merck and resin producer SABIC to develop laser-marking technology and materials to ease the recycling process for LDPE, LLDPE packaging film.

    The results of the collaboration will be presented at K 2019.

    Chun-Yip Pang, Clariant’s Global Product Manager Additive Masterbatches – Laser, said: “This collaboration is focused on eliminating the printing ink used for tracking, shelf-life, bar codes and other variable information that must be placed on almost any package on the market. Less ink means less contamination when it comes to recycling.”

    The collaboration demonstrates a complete supply-chain solution for laser-marking of films. As the resin supplier, SABIC contributes the polymer technology that delivers the properties required in the film packaging. SABIC can also supply a wide variety of polymers in its portfolio as a certified circular polymer, contributing even more to sustainable packaging.

    Laser-sensitive Iriotec pigments and marking expertise are provided by Merck, while Clariant developed the additive masterbatch formulations for use in film extrusion.

    Because most plastics are transparent to the radiation used in laser-marking, the additives are necessary for a visible reaction in the film. The marks are permanent and resistant to water, oil, grease or fatty foods. They can be applied to the surface of a mono-layer film, or a laser-sensitive layer can be placed behind a laser-transparent surface layer.

    The additives provide excellent contrast and allow high-speed marking.

    At K 2019, the collaborators will show several examples of laser-marked packaging films and pouches.

    For this year’s K Show, Marchante SAS reaffirms its commitment to productivity, efficiency and high-quality machinery, and will proudly celebrate Director Inocente Marchante’s 40 years in the Biax industry.

    Marchante began his carrier in the Biax industry in 1979 and has been hailed as a game-changer in production processes and machinery developments for more than 150 lines worldwide for BOPP, BOPET, BOPS, BOPA, PETG.

    As the Technical Director in charge of technological process of plastic materials, stretching and transformation, he is the inventor of the first Mechanical Simultaneous systems on the market, and firmly believes in simultaneous stretching for the sake of production simplification, energy cost reduction, and the transition to promising material developments.

    Gathering biax experts, he founded family-owned company Marchante SAS to support film producers through their projects. He began implementing sophisticated films and delicate processes, of which the Simultaneous Stretcher MASIM, for packaging, food, automotive and energy industries, is one.

    The MASIM is a modular Simultaneous Stretching system that has proved its efficiency in terms of high homogeneity results and optimum mechanical properties for delicate films such as Battery Separator film for Lithium based batteries, PA, or PE, and is now available for PS, PI or PTFE.

    The clips are designed to stretch thin film down to 5μm, and mostly to reduce edge waste creation during production due to the very short distance clip-to-clip before and after stretching.

    With the thinnest clips on the market, film thickness and flatness is ensured from inlet to outlet without turbulence, thus producing an optimal width of high grade film.

    As a manufacturer of machinery for bi-oriented film producers, Marchante SAS pursues engagement towards and with a more efficient and cleaner industry. To this end, the company is developing a process to produce sheets for thermoforming, with 100 per cent rPET.
