High-opacity papers

Color kraft papers with opacity of 99% or above are ideal for envelopes that will be used to carry sensitive information. The opacity ensures the printed content inside the envelope is not visible from the outside. Because they don’t require reverse surface confidentiality printing, envelopes made from these papers help reduce work processes. The papers are also highly suitable for bag production, including those involving glue application.
