Antigrasa TMSL ECO-7 FC: Greaseproof and Heat-Sealable Barrier for Food Packaging
The Antigrasa TMSL ECO-7 FC coating is a high-performance functional technical barrier designed for flexographic application. This advanced system prevents the penetration of oils and greases while enabling the direct heat-sealing of the packaging (paper, cardboard, or hybrid structures), complying with the most stringent food contact requirements. By forming a sealing and repellent layer, it preserves the visual and mechanical integrity of the substrate, eliminates the formation of stains or grease halos, and allows for highly reliable heat closures. Its application reduces the need to laminate additional layers, minimizing conversion costs and facilitating the transition towards more sustainable, monomaterial packaging.
Operational Advantages on Press
- Superior oil and grease repellency: Prevents the appearance of transparencies, stains, and the structural weakening of the substrate caused by lipid absorption, ensuring excellent shelf appeal for the final packaging.
- Direct and consistent heat-sealing: Enables secure heat sealing with a wide process window (temperature, time, and pressure), achieving high seal strength (peel/tear resistance) ideal for demanding logistics and end-use.
- Printability and process optimization: Creates a uniform surface that reduces mottle and provides excellent ink anchorage. It guarantees stable performance in subsequent conversion processes such as die-cutting, creasing, and folding.
- Efficiency and sustainability: Facilitates the development of monomaterial designs (heat-sealable paper/cardboard), reducing the use of laminated plastics and simplifying the packaging structure. Water-based option with low VOC emissions.
- Maximum safety and food compliance: Formulated for direct and indirect food contact. It maintains total sensory neutrality (no alteration of odor or taste) and ensures minimum migration levels according to testing.
