Lecta has announced the expansion of its Metalvac range with the Metalvac Seal Oxygen Barrier, a metallized barrier paper aiming to meet industry demands for technical performance, industrial efficiency and sustainability.
Lecta says its Metalvac range offers various paper grades with heat sealability and light, water vapour, oxygen and aroma barriers, as well as resistance to moisture and grease (PFAS-free). The papers are said to ensure efficiency throughout the production process, and the low aluminium content (0.08 gsm) ensures high barrier performance without compromising the material’s recyclability within the standard paper recycling stream.
The new paper is 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, and pet food.
Available in weights of 83 and 93 gsm, the Metalvac Seal Oxygen Barrier paper can be printed in offset, flexography and rotogravure on its coated side, and its metallized backside is heat sealable. Lecta adds that it also ensures “very good” performance on horizontal and vertical form-fill-seal machines as well as optimal conversion into common flexible packaging formats such as sachets, flowpacks and doypacks.
Lecta introduced its Linerset FP barrier base paper for converters and printers in March, designed for flexible packaging and seeking to offer a strong translucent alternative for bags, pouches and wrapping applications. The material is said to be suitable for a wide range of applications including food and industrial packaging and is available in a variety of grammages.
In related news, Delfort unveiled its new heat and cold-sealable barrier paper designed to protect foods such as ice cream, chocolates and sweets and provide an alternative to traditional materials. The paper apparently provides robust protection against external elements to ensure the taste, appearance and texture of foods.
