Cortec Introduces EcoShield Paper, Linerboard

Cortec Corp., St. Paul, Minn., USA, has introduced EcoShield® paper and linerboard made from high-quality recycled paper. The packaging product is coated with a water-based barrier coating and is fully recyclable and repulpable.

The paper can be recycled into other types of paper products such as boxes, cardboard, and other corrugated materials. It also can be repulped—made into or mixed with pulp to make new paper products. There is no need to separate the paper base from the coating. This environmentally safe product is oil- and grease-resistant, combining moisture barrier properties and oil and grease resistivity into one step.

In addition to being safe for the environment, the product complies with FDA regulations under the Code of Federal Regulations Title 21 for food contact. It can be used in applications in which direct or indirect food contact may occur. In the manufacturing process, there is no chlorine or other bleaching chemicals, which eliminates package contamination.

The paper also displays a reduced moisture vapor transmission rate (MVTR), meaning it has an MVTR value similar to polycoated papers and better than waxed papers while being biobased and environmentally friendly, the company says.

The coating helps to protect items that are sensitive to moisture. The items may be wrapped in the special paper or packaged in boxes that have been made with the coated linerboard. The product is nontoxic, nonirritating, and nitrite- and amine-free. It does not contain any silicones, chromates, or other heavy metals.

The product was tested according to the Fibre Box Association’s voluntary standard for repulpability and also was tested according to ASTM E-96’s standard for water vapor transmission of materials, Cortec notes..
