Moisture Barrier Paper


Cortec® presents patented EcoShield® Paper and Linerboard - premium paper in the industry made from the highest quality recycled paper. This innovative, safe and economical packaging product is coated with a water based barrier coating and is fully recyclable / repulpable while displaying barrier properties better than those of wax or polyethylene coated paper or linerboards. 

Contrary to other barrier packaging products EcoShield® Paper can readily be recycled into other types of paper products such as boxes, cardboard and other corrugated materials as well as “repulped”: made into or mixed with pulp to make new paper products. There is no need for costly processes to separate the paper base from the coating. This environmentally safe product also shows excellent oil and grease resistance perfectly combining moisture barrier properties and oil and grease resistivity into one step. In addition to being safe to the environment, EcoShield® is in compliance with FDA regulations under 21 code of Federal Regulations for food contact. It can be used in applications where direct or indirect food contact may occur. In manufacturing process there is no chlorine or other bleaching chemicals which completely eliminates package contamination found with other papers on the market.  Developed in Cortec® laboratories utilizing high-tech, patented, recyclable and repulpable technology, EcoShield® Paper also displays a greatly reduced Moisture Vapor Transmission Rate (MVTR). In other words it has a MVTR value similar to polycoated papers and superior to waxed papers while still being biobased, economical and environmentally friendly.
