ProPoly and Eco Select fibers are refined to achieve an equally functional barrier prior to additional barrier treatments, providing inherent oil/grease resistance. The paper fiber refining process creates a ‘tortuous path’ barrier from which it is more difficult for oil to escape. And, by starting with a superior sheet, high-performing barriers can be built with less fluorochemical treatment.
ProPly and Eco Select papers are also highly char resistant, which is particularly important for increasingly popular single-serve bags that generate heat more quickly due to their smaller size. The papers are also flexographic printable offering a high degree of ink holdout, helping to eliminate bleed through that can build up during processing.
The company’s Eco Select papers further provide a ‘natural’ look conveying eco-responsibility to consumers and can be Forest Stewardship Council (FSC) certified, meaning the paper is sourced from responsibly managed, sustainable forests.
