Speed-E is a brand of offset papers designed for the printing of books, textbooks, posters, advertising materials etc. The paper is manufactured in Kwidzyn, in the production plant owned by the International Paper Polska – Kwidzyn Sp. z o.o. limited liability company. The wood used for its production has the FSC Mixed certificate which means that at least 70% of raw material used is FSC-certified, while the uncertified rest is the so-called Controlled Wood. Cellulose fibres are bleached without the use of the most environmentally harmful gaseous chlorine (ECF paper), as are other paper products made in the Kwidzyn plant.
