Lecta, a company specializing in the design and development of paper-based solutions for flexible packaging, is expanding its flagship Metalvac range with Metalvac Seal Oxygen Barrier— a new metallized barrier paper that meets the current industry demands for technical performance, industrial efficiency, and sustainability.
The Metalvac range offers various paper grades with heat-sealability and light, water vapor, oxygen, and aroma barriers, as well as resistance to moisture and grease (PFAS-free). These metallized papers stand out for their excellent runnability and adaptability to standard packing lines on the market, ensuring efficiency throughout the production process.
Its low aluminum content (0.08 gsm) ensures high barrier performance without compromising the material's recyclability within the standard paper recycling stream.
Metalvac Seal Oxygen Barrier is an innovative barrier paper, intended as a more sustainable alternative to existing plastic, foil, and laminate solutions used for packaging food products such as snacks; sweet and chocolate confectionery; coffee, tea, and infusions; spices and seasonings; ingredients and other powdered products; pet food, and more.
This new barrier paper is available in weights of 83 and 93 gsm and can be printed — in offset, flexography, and rotogravure — on its coated side, while its high-vacuum metallized backside is heat-sealable.
It offers excellent barrier properties (both flat and folded) against water vapor (WVTR), oxygen (OTR), aroma, mineral oils (MOSH/MOAH), and grease (PFAS-free), while also ensuring very good performance on horizontal and vertical form-fill-seal machines (HFFS/VFFS), as well as optimal conversion into common flexible packaging formats such as sachets, flowpacks, doypacks, and more.
Metalvac Seal Oxygen Barrier is recyclable within the standard paper and cardboard recycling stream, in accordance with CEPI V2 recyclability standards. This new metallized barrier paper also aligns with circular economy principles and represents an efficient, more sustainable alternative for multiple flexible packaging applications.
