FIELD: process engineering.
SUBSTANCE: invention relates to production of plywood articles yielding to subsequent forming, method of its fabrication and self-adhesives. Proposed article is produced by jointing plywood sheets together. Note here that said sheets are jointed by self-adhesive made of polyolefin film. Note here that said polyolefin film comprises polyolefin functionalised by maleic acid derivative and including reactive groups of maleic anhydride capable of reacting with OH-groups of wood to form covalent bonds between sheet and film. Note also that said polyolefin film comprises, at least three layers and outer layers 1, 2 represent self-adhesive layers reacting with OH-groups of wood.
EFFECT: higher quality, duration and stability.
