White envelopes for correspondence. The envelopes are covered on the inside with a colored layer. This procedure is usually applied to white envelopes made of low-grammage paper and aims to reduce the transparency of the paper. The main advantage of internal printing is increased confidentiality, thus protecting the information inside the envelopes.
