Abstract: A stock size intended to be added as a solution to the pulp stock in connection with the manufacture of paper or board in order to improve the characteristics of the paper or board, e.g.), to reduce the absorption of liquids, to increase the dry strength and wet strength. The stock size contains a polymer, which is based on styrene maleic acid and stabilised with a polysaccharide, such as cationic starch. The stock size is advantageously prepared in a steam jet cooker. The stock size is suitably used as a stock size in the manufacturing of liquid packaging board.

Abstract: An intermediate for a mailer type business form is provided that is Z-folded to produce a mailer type business form with built-in reply envelope. The mailer type business form is adapted to be used either as a mailing label or as a one-piece mailer. The mailer is of compact size, for example, about 7 inches×4 inches so as to facilitate its use as a mailing label on relatively small packages. First and second panels of the mailer define a reply envelope when the mailer is Z-folded. The third panel of the mailer is adapted to include invoice and/or remittance advice and may include a line of weakness to define a stub that can be inserted in the reply envelope with a check. The intermediate is printed in a rotated format to provide two forms about fourteen inches and also has rewettable glue and additional cohesive to create a postal compatible reply envelope.
