Lecta launches Metalvac Seal Oxygen Barrier paper

Lecta has expanded 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 barriers against light, water vapor, oxygen and aroma, as well as resistance to moisture and grease (PFAS-free). These metallized papers offer 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 designed as a more sustainable alternative to existing plastics, foils, and laminates used for packaging food products, including snacks, sweets, chocolate confectionery, coffee, tea, infusions, spices, seasonings, 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. Its high-vacuum metallized backside is heat-sealable.

Metalvac Seal Oxygen Barrier 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.

The new product is recyclable within the standard paper and cardboard recycling stream, in accordance with CEPI V2 recyclability standards. It also aligns with circular economy principles and represents an efficient, more sustainable alternative for multiple flexible packaging applications.

The entire Metalvac range is produced in accordance with Good Manufacturing Practices (GMP) and Food Safety (FSSC 22000) standards, which are essential for the food sector, as well as environmental management standards ISO 14001 and EMAS, energy efficiency standards ISO 50001, quality management standards ISO 9001, and occupational health and safety standards ISO 45001. Additionally, it is available upon request with PEFC or FSC C011032 Chain of Custody forest certifications.
