Third party analysis commissioned in 2016 revealed that the typical silicone coated paper carrier of self adhesive labels meets the biodegradability and compostability requirements of EN 14046:2003 and EN 13432 standards. Paper is made from fully renewable natural resources, is recyclable and biodegradable in a short time. The study intended to assess the impact of coating a silicone layer on the paper surface – an operation typically performed by Ahlstrom-Munksjö’s customers – on the biodegradability and compostability of the material. Release papers are coated with a layer of silicone to serve as the release carriers of self-adhesive labels through printing, cutting and application to a wide range of products.
These tests prove that silicone coated release papers remain both biodegradable and compostable, like the paper substrate they are based on. Recycling always represents a preferred end of life option, and surveys report that paper recycling rates in Europe are the highest among various materials, even in the specific field of release liners. Additionally, thanks to biodegradability, the environmental impact of residual paper release liner waste, eventually not recycled at the end of its life cycle, will be lower than that of materials based on non-renewable resources. The study was performed by Ecol Studio, an environmental analysis laboratory accredited by Italy’s National Accreditation Body Accredia, in compliance with ISO 17025:2005 standards and EN 45000 European norms.
