Abstract

620,139. Compound paper. SPOLEK PRO CHEMICOU A HUTNI VYROBU, NARODNI PODNIK. March 7, 1946, No. 7173. Convention date, March 22, 1944. [Classes 96 and 140] A laminated paper for wrapping or for making drinking-vessels consists of three layers, each of a different kind of paper, the middle layer being of a thin waterproof and greaseproof paper and the outer layers being neither waterproof not greaseproof, the three layers being connected by means of a synthetic resin adhesive such as urea-aldehyde resin. The middle layer, which may also be airtight, may be paper impregnated with urea-aldehyde resin, or parchment paper. The inner layer may be of thin, rough and coarse paper, the outer layer of smooth absorbent paper capable of being printed.
